Silicon Alley

Silicon Alley is a nickname for an area with a concentration of Internet and new media companies in Manhattan, New York City. Originally, the term referred to the cluster of such companies extending from the Flatiron District down to SoHo and TriBeCa along the Broadway corridor, but as the location of these companies spread out, it became a general term referring to the dot com industry in New York City as a whole.
The term was in most common use in the late 1990s, when companies such as Agency.com, Razorfish, Medscape, inet-d and The Mining Company (now About.com), became success stories with successful private buyouts or IPOs.
The first publication to cover Silicon Alley was @NY, an online newsletter founded in the summer of 1995 by Tom Watson and Jason Chervokas. The first magazine to focus on the venture capital opportunities in Silicon Alley, AlleyCat News co-founded by Anna Copeland Wheatley and Janet Stites, was launched in the fall of 1996. Courtney Pulitzer branched off from her @The Scene column with @NY and created Courtney Pulitzer's Cyber Scene and her popular networking events Cocktails with Courtney. First Tuesday, co-founded by Vincent Grimaldi de Puget and John Grossbart, became the largest gathering of Silicon Alley, welcoming 500 to 1000 venture capitalists and entrepreneurs every month. It was an initiative of law firm Sonnenschein and the Kellogg School of Management, as well as other corporate founders, including Accenture (then Andersen Consulting), AlleyCat News and Merrill Lynch. Silicon Alley Reporter started publishing in October 1996. It was founded by Jason Calacanis and was in business from 1996-2001. @NY, print magazines, and the attending media coverage by the larger New York press helped to popularize both the name, and the idea of New York City as a dot-com center.
In 1997, over 200 members and leaders of Silicon Alley joined NYC entrepreneurs, Andrew Rasiej and Cecilia Pagkalinawan to help wire Washington Irving High School to the internet. This response and the Department of Education's growing need for technology integration marked the birth of MOUSE, an organization that today serves tens of thousands of underserved youth in schools in five states and over 20 countries. After the bubble burst, Silicon Alley Reporter was rebranded as Venture Reporter in September 2001 and sold to Dow Jones. Self-financed AlleyCat News ceased publication in October 2001.
A couple of years after the internet bust, Silicon Alley began making its comeback with the help of NY Tech meetup and NextNY. Since 2003 Silicon Alley has seen a steady growth in the number of start-ups and has joined the ranks of Boston and San Francisco as one of the three leading technology centers in the United States. As of 2007 Google's second largest office is located in New York. And, as of 2009, New York's Silicon Alley has become the startup leader in advertising, new media, financial technologies such as Eyeblaster, DoubleClick, Roo, IAC, meetup.com and a slew of web 2.0 companies. According to the National Venture Capital Association, 247 venture capital deals worth $1.4 billion closed in New York in 2009, despite the recession and rocky market. New York still ranks third behind Silicon Valley and Boston in the number of deals and overall investment rates, but New York is holding its own against the other big hubs and possibly beginning to increase its share.
Silicon Alley has also become the home to a significant number of European, Australian, and particularly Israeli startups that have taken advantage of New York City's central location and the 7 hours time difference between the developing team in Israel and the business team in New York that is more manageable than the 10 hours difference between Israel and California's Silicon Valley.
The name is derived from Silicon Valley, California.

WorldCall
TypeMultimedia Service Provider
IndustryTelecommunication
Founded1996
Headquarters Pakistan
Key peopleSalman Taseer
Websitewww.worldcall.pk
WorldCALL is a telecommunication operator in Pakistan which provides services such as Cable TV, Broadband Internet, 3G EVDO Internet, pay-phone services, dial-up Internet cards and wireless telephone. It was established in 1996 by First Capital Securities Corporation .

History

In 1996, First Capital Securities Corporation began to incubate a payphone operation called Worldcall Payphones Limited. At that time, notable development was being done to improve the payphone infrastructure in the country. The first payphone was installed in June 1996. Now, Worldcall has over 70,000 payphones all over the country and the company has become one of the largest fixed line payphone operator and the pioneers of “Supervised Payphones” business model in Pakistan.

Prepaid Calling Cards

In 1998 prepaid calling cards were launched by Worldcall Phonecards under the brand name "Hello". In the following year the group established dial-up internet services through Worldcall Dot Com.

Overseas Operations

In 1999 Worldcall Telecom Lanka established the Groups' first overseas presence when payphone operations were established in Sri Lanka.

Cable and Internet Services

In 2000 Worldcall Multimedia established a Hybrid Fiber Coaxial (HFC) scalable network in Lahore thus becoming the first Multi-service operator in the country, providing cable television and Internet-over-cable. In cable TV in Lahore, Worldcall was the last entrant and by far the largest. In 2003 the company launched an HFC network operation in Karachi under Worldcall Broadband Limited (WBL). These were the largest and only national networks capable of triple play (cable TV, high speed internet/data and telephony) until the introduction of Wateen Telecom. The broadband division also offers metro fiber lease to a number of other telecom / cellular operators as well as corporates. Currently Worldcall is one of the few operators who are providing Digital Cable in Lahore, Karachi and Islamabad.

Wireless Local Loop Services

Worldcall Telecom Limited acquired Wireless Local Loop (WLL) licenses/spectrum in the post deregulation auction to provide WLL telephony in all 14 telecom regions of Pakistan primarily in the 1900 MHz band. It has partnered with Samsung for a CDMA 2000 1x solution (with EVDO option). WTL started service from Lahore in June 2005 which is now available in over 40 cities. WTL also acquired an LDI license and service commenced at the end of 2004. WTL has increased competition due to rights to dark fibers in a national long haul network which is being built across Pakistan.

Wi-Fi,wireless internet

Wi-Fi logo,

Wi-Fi,waɪfaɪ, is a trademark of the Wi-Fi Alliance. It is not a technical term. However, the Alliance has generally enforced its use to describe only a narrow range of connectivity technologies including wireless local area network (WLAN) based on the IEEE 802.11 standards, device to device connectivity [such as Wi-Fi Peer to Peer AKA Wi-Fi Direct], and a range of technologies that support PAN, LAN and even WAN connections. Derivative terms, such as Super Wi-Fi, coined by the U.S. Federal Communications Commission (FCC) to describe proposed networking in the former UHF TV band in the US, may or may not be sanctioned by the Alliance. As of November 2010 this was very unclear.
The technical term "IEEE 802.11" has been used interchangeably with Wi-Fi, however Wi-Fi has become a superset of IEEE 802.11 over the past few years. Wi-Fi is used by over 700 million people, there are over 750,000 hotspots (places with Wi-Fi Internet connectivity) around the world, and about 800 million new Wi-Fi devices every year. Wi-Fi products that complete the Wi-Fi Alliance interoperability certification testing successfully can use the Wi-Fi CERTIFIED designation and trademark.
Not every Wi-Fi device is submitted for certification to the Wi-Fi Alliance. The lack of Wi-Fi certification does not necessarily imply a device is incompatible with Wi-Fi devices/protocols. If it is compliant or partly compatible the Wi-Fi Alliance may not object to its description as a Wi-Fi device though technically only the CERTIFIED designation carries their approval.
Wi-Fi certified and compliant devices are installed in many personal computers, video game consoles, MP3 players, smartphones, printers, digital cameras, and laptop computers.
This article focuses on the certification and approvals process and the general growth of wireless networking under the Wi-Fi Alliance certified protocols. For more on the technologies see the appropriate articles with IEEE, ANSI, IETF , W3 and ITU prefixes (acronyms for the accredited standards organizations that have created formal technology standards for the protocols by which devices communicate). Non-Wi-Fi-Alliance wireless technologies intended for fixed points such as Motorola Canopy are usually described as fixed wireless. Non-Wi-Fi-Alliance wireless technologies intended for mobile use are usually described as 3G, 4G or 5G reflecting their origins and promotion by telephone/cell companies.


Wi-Fi certification

See also: Wi-Fi Alliance
Wi-Fi technology builds on IEEE 802.11 standards. The IEEE develops and publishes some of these standards, but does not test equipment for compliance with them. The non-profit Wi-Fi Alliance formed in 1999 to fill this void — to establish and enforce standards for interoperability and backward compatibility, and to promote wireless local-area-network technology. As of 2010 the Wi-Fi Alliance consisted of more than 375 companies from around the world. Manufacturers with membership in the Wi-Fi Alliance, whose products pass the certification process, gain the right to mark those products with the Wi-Fi logo.
Specifically, the certification process requires conformance to the IEEE 802.11 radio standards, the WPA and WPA2 security standards, and the EAP authentication standard. Certification may optionally include tests of IEEE 802.11 draft standards, interaction with cellular-phone technology in converged devices, and features relating to security set-up, multimedia, and power-saving.
Most recently, a new security standard, Wi-Fi Protected Setup, allows embedded devices with limited graphical user interface to connect to the Internet with ease. Wi-Fi Protected Setup has 2 configurations: The Push Button configuration and the PIN configuration. These embedded devices are also called The Internet of Things and are low-power, battery-operated embedded systems. A number of Wi-Fi manufacturers design chips and modules for embedded Wi-Fi, such as GainSpan. 

The name Wi-Fi

The term Wi-Fi suggests Wireless Fidelity, resembling the long-established audio-equipment classification term high fidelity (in use since the 1930s) or Hi-Fi (used since 1950). Even the Wi-Fi Alliance itself has often used the phrase Wireless Fidelity in its press releases and documents;the term also appears in a white paper on Wi-Fi from ITAA. However, based on Phil Belanger's statement, the term Wi-Fi was never supposed to mean anything at all.
The term Wi-Fi, first used commercially in August 1999, was coined by a brand-consulting firm called Interbrand Corporation that the Alliance had hired to determine a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'".Belanger also stated that Interbrand invented Wi-Fi as a play on words with Hi-Fi, and also created the yin-yang-style Wi-Fi logo.
The Wi-Fi Alliance initially used an advertising slogan for Wi-Fi, "The Standard for Wireless Fidelity", but later removed the phrase from their marketing. Despite this, some documents from the Alliance dated 2003 and 2004 still contain the term Wireless Fidelity. There was no official statement related to the dropping of the term.
The yin-yang logo indicates the certification of a product for interoperability. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs. X.25 was an important early WAN protocol, and is often considered to be the "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.
Academic research into wide area networks can be broken down into three areas: Mathematical models, network emulation and network simulation.
Performance improvements are sometimes delivered via WAFS or WAN optimization.

Uses

Internet access


A roof-mounted Wi-Fi antenna
A Wi-Fi enabled device such as a personal computer, video game console, smartphone or digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more (interconnected) access points — called hotspots — can comprise an area as small as a few rooms or as large as many square miles. Coverage in the larger area may depend on a group of access points with overlapping coverage. Wi-Fi technology has been used in wireless mesh networks, for example, in London, UK.
In addition to private use in homes and offices, Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients. Enthusiasts or authorities who wish to provide services or even to promote business in selected areas sometimes provide free Wi-Fi access. As of 2008 more than 300 metropolitan-wide Wi-Fi (Muni-Fi) projects had started. As of 2010 the Czech Republic had 1150 Wi-Fi based wireless Internet service providers.
Routers that incorporate a digital subscriber line modem or a cable modem and a Wi-Fi access point, often set up in homes and other premises, can provide Internet access and internetworking to all devices connected (wirelessly or by cable) to them. With the emergence of MiFi and WiBro (a portable Wi-Fi router) people can easily create their own Wi-Fi hotspots that connect to Internet via cellular networks. Now many mobile phones can also create wireless connections via tethering on iPhone, Android, Symbian, and WinMo.
One can also connect Wi-Fi devices in ad-hoc mode for client-to-client connections without a router. Wi-Fi also connects places that would traditionally not have network access, for example bathrooms, kitchens and garden sheds.

City-wide Wi-Fi
Further information: Municipal wireless network

In the early 2000s, many cities around the world announced plans for city-wide Wi-Fi networks. This proved to be much more difficult than their promoters initially envisioned with the result that most of these projects were either canceled or placed on indefinite hold. A few were successful, for example in 2005, Sunnyvale, California became the first city in the United States to offer city-wide free Wi-Fi.
In May, 2010, London, UK Mayor Boris Johnson pledged London-wide Wi-Fi by 2012. Both the City of London, UK and Islington  already have extensive outdoor Wi-Fi coverage.
Campus-wide Wi-Fi
Carnegie Mellon University built the first wireless Internet network in the world at their Pittsburgh campus in 1994, long before Wi-Fi branding originated in 1999. Many traditional college campuses provide at least partial wireless Wi-Fi Internet coverage.

Drexel University in Philadelphia made history by becoming the United State's first major university to offer completely wireless Internet access across the entire campus in 2000.

Direct computer-to-computer communications
Wi-Fi also allows communications directly from one computer to another without the involvement of an access point. This is called the ad-hoc mode of Wi-Fi transmission. This wireless ad-hoc network mode has proven popular with multiplayer handheld game consoles, such as the Nintendo DS, digital cameras, and other consumer electronics devices.
Similarly, the Wi-Fi Alliance promotes a pending specification called Wi-Fi Direct for file transfers and media sharing through a new discovery- and security-methodology.

Future directions
As of 2010 Wi-Fi technology has spread widely within business and industrial sites. In business environments, just like other environments, increasing the number of Wi-Fi access points provides network redundancy, support for fast roaming and increased overall network-capacity by using more channels or by defining smaller cells. Wi-Fi enables wireless voice-applications (VoWLAN or WVOIP). Over the years, Wi-Fi implementations have moved toward "thin" access points, with more of the network intelligence housed in a centralized network appliance, relegating individual access points to the role of "dumb" transceivers. Outdoor applications may utilize mesh topologies.

Advantages and challenges

Operational advantages
Wi-Fi allows the deployment of local area networks (LANs) without wires for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs.
As of 2010 manufacturers are building wireless network adapters into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in even more devices. Wi-Fi has become widespread in corporate infrastructures.
Different competitive brands of access points and client network-interfaces can inter-operate at a basic level of service. Products designated as "Wi-Fi Certified" by the Wi-Fi Alliance are backwards compatible. "Wi-Fi" designates a globally operative set of standards: unlike mobile phones, any standard Wi-Fi device will work anywhere in the world.
Wi-Fi operates in more than 220,000 public hotspots and in tens of millions of homes and corporate and university campuses worldwide. The current version of Wi-Fi Protected Access encryption (WPA2) as of 2010 is considered secure, provided users employ a strong passphrase. New protocols for quality-of-service (WMM) make Wi-Fi more suitable for latency-sensitive applications (such as voice and video); and power saving mechanisms (WMM Power Save) improve battery operation.

Limitations
Spectrum assignments and operational limitations are not consistent worldwide: most of Europe allows for an additional two channels beyond those permitted in the U.S. for the 2.4 GHz band (1–13 vs. 1–11), while Japan has one more on top of that (1–14). Europe, as of 2007, was essentially homogeneous in this respect.
A Wi-Fi signal occupies five channels in the 2.4 GHz band; any two channels whose channel numbers differ by five or more, such as 2 and 7, do not overlap. The oft-repeated adage that channels 1, 6, and 11 are the only non-overlapping channels is, therefore, not accurate; channels 1, 6, and 11 do, however, comprise the only group of three non-overlapping channels in the U.S.
Equivalent isotropically radiated power (EIRP) in the EU is limited to 20 dBm (100 mW).

Reach
See also: Long-range Wi-Fi
Wi-Fi networks have limited range. A typical wireless router using 802.11b or 802.11g with a stock antenna might have a range of 32 m (120 ft) indoors and 95 m (300 ft) outdoors. The IEEE 802.11n however, can exceed that range by more than two times.[28] Range also varies with frequency band. Wi-Fi in the 2.4 GHz frequency block has slightly better range than Wi-Fi in the 5 GHz frequency block. Outdoor ranges - through use of directional antennas - can be improved with antennas located several kilometres or more from their base. In general, the maximum amount of power that a Wi-Fi device can transmit is limited by local regulations, such as FCC Part 15 in USA.
Due to reach requirements for wireless LAN applications, Wi-Fi has fairly high power consumption compared to some other standards. Technologies such as Bluetooth (designed to support wireless PAN applications) provide a much shorter propagation range of <10m and so in general have a lower power consumption. Other low-power technologies such as ZigBee have fairly long range, but much lower data rate. The high power consumption of Wi-Fi makes battery life in mobile devices a concern.
Researchers have developed a number of "no new wires" technologies to provide alternatives to Wi-Fi for applications in which Wi-Fi's indoor range is not adequate and where installing new wires (such as CAT-5) is not possible or cost-effective. For example, the ITU-T G.hn standard for high speed Local area networks uses existing home wiring (coaxial cables, phone lines and power lines). Although G.hn does not provide some of the advantages of Wi-Fi (such as mobility or outdoor use), it's designed
 for applications (such as IPTV distribution) where indoor range is more important than mobility.
Due to the complex nature of radio propagation at typical Wi-Fi frequencies, particularly the effects of signal reflection off trees and buildings, algorithms can only approximately predict Wi-Fi signal strength for any given area in relation to a transmitter.
 This effect does not apply equally to long-range Wi-Fi, since longer links typically operate from towers that broadcast above the surrounding foliage.

Mobility


Speed vs. Mobility of wireless systems: Wi-Fi, HSPA, UMTS, GSM
The very limited practical range of Wi-Fi essentially confines mobile use to such applications as inventory-taking machines in warehouses or in retail spaces, barcode-reading devices at check-out stands, or receiving/shipping stations. Mobile use of Wi-Fi over wider ranges is limited, for instance, to uses such as in an automobile moving from one hotspot to another (known as Wardriving). Other wireless technologies are more suitable as illustrated in the graphic.

Data security risks
The most common wireless encryption-standard, Wired Equivalent Privacy (WEP), has been shown to be easily breakable even when correctly configured. Wi-Fi Protected Access (WPA and WPA2) encryption, which became available in devices in 2003, aimed to solve this problem. Wi-Fi access points typically default to an encryption-free (open) mode. Novice users benefit from a zero-configuration device that works out-of-the-box, but this default does not enable any wireless security, providing open wireless access to a LAN. To turn security on requires the user to configure the device, usually via a software graphical user interface (GUI). On unencrypted Wi-Fi networks connecting devices can monitor and record data (including personal information), but such networks may use other means of protection, such as a virtual private network or secure Hypertext Transfer Protocol (HTTPS) and Transport Layer Security.

Population
Many 2.4 GHz 802.11b and 802.11g access-points default to the same channel on initial startup, contributing to congestion on certain channels. To change the channel of operation for an access point requires the user to configure the device.

Channel pollution
For more details on this topic, see Electromagnetic interference at 2.4 GHz.
Market forces may drive a process of standardization. Interoperability issues between non-Wi-Fi brands or proprietary deviations from the standard can still disrupt connections or lower throughput speeds on all devices within range, including any non-Wi-Fi or proprietary product. Moreover, the usage of the ISM band in the 2.45 GHz range is also common to Bluetooth, WPAN-CSS, ZigBee, and any new system will take its share.
Wi-Fi pollution, or an excessive number of access points in the area, especially on the same or neighboring channel, can prevent access and interfere with other devices' use of other access points, caused by overlapping channels in the 802.11g/b spectrum, as well as with decreased signal-to-noise ratio (SNR) between access points. This can become a problem in high-density areas, such as large apartment complexes or office buildings with many Wi-Fi access points. Additionally, other devices use the 2.4 GHz band: microwave ovens, security cameras, ZigBee devices, Bluetooth devices and (in some countries) Amateur radio, video senders, cordless phones and baby monitors, all of which can cause significant additional interference. It is also an issue when municipalitiesor other large entities (such as universities) seek to provide large area coverage.

Hardware


Standard devices

OSBRiDGE 3GN - 802.11n Access Point and UMTS/GSM Gateway in one device


USB wireless adapter
A wireless access point (WAP) connects a group of wireless devices to an adjacent wired LAN. An access point resembles a network hub, relaying data between connected wireless devices in addition to a (usually) single connected wired device, most often an ethernet hub or switch, allowing wireless devices to communicate with other wired devices.
Wireless adapters allow devices to connect to a wireless network. These adapters connect to devices using various external or internal interconnects such as PCI, miniPCI, USB, ExpressCard, Cardbus and PC Card. As of 2010, most newer laptop computers come equipped with internal adapters. Internal cards are generally more difficult to install.
Wireless routers integrate a Wireless Access Point, ethernet switch, and internal router firmware application that provides IP routing, NAT, and DNS forwarding through an integrated WAN-interface. A wireless router allows wired and wireless ethernet LAN devices to connect to a (usually) single WAN device such as a cable modem or a DSL modem. A wireless router allows all three devices, mainly the access point and router, to be configured through one central utility. This utility is usually an integrated web server that is accessible to wired and wireless LAN clients and often optionally to WAN clients. This utility may also be an application that is run on a desktop computer such as Apple's AirPort.
Wireless network bridges connect a wired network to a wireless network. A bridge differs from an access point: an access point connects wireless devices to a wired network at the data-link layer. Two wireless bridges may be used to connect two wired networks over a wireless link, useful in situations where a wired connection may be unavailable, such as between two separate homes.
Wireless range-extenders or wireless repeaters can extend the range of an existing wireless network. Strategically placed range-extenders can elongate a signal area or allow for the signal area to reach around barriers such as those pertaining in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput limited by the "weakest link" between the two nodes in the chain from which the connection originates to where the connection ends.

Distance records
Distance records (using non-standard devices) include 382 km (237 mi) in June 2007, held by Ermanno Pietrosemoli and EsLaRed of Venezuela, transferring about 3 MB of data between the mountain-tops of El Águila and Platillon. The Swedish Space Agency transferred data 420 km (260 mi), using 6 watt amplifiers to reach an overhead stratospheric balloon.

Embedded systems


Embedded serial-to-Wi-Fi module
Increasingly in the last few years (particularly as of 2007), embedded Wi-Fi modules have become available that incorporate a real-time operating system and provide a simple means of wirelessly enabling any device which has and communicates via a serial port.This allows the design of simple monitoring devices. An example is a portable ECG device monitoring a patient at home. This Wi-Fi-enabled device can communicate via the Internet.
These Wi-Fi modules are designed so that implementers need only minimal Wi-Fi knowledge to provide Wi-Fi connectivity for their products.

Network security

The main issue with wireless network security is its simplified access to the network compared to traditional wired networks such as ethernet.[citation needed] With wired networking one must either gain access to a building (physically connecting into the internal network) or break through an external firewall. Most business networks protect sensitive data and systems by attempting to disallow external access. Enabling wireless connectivity provides an attack vector, particularly if the network uses inadequate or no encryption.
An attacker who has gained access to a Wi-Fi network router can initiate a DNS spoofing attack against any other user of the network by forging a response before the queried DNS server has a chance to reply.

Securing methods
A common but unproductive measure to deter unauthorized users involves suppressing the access point's SSID broadcast. This is ineffective as a security method because the SSID is broadcast in the clear in response to a client SSID query. Another unproductive method is to only allow computers with known MAC addresses to join the network. But intruders can defeat this method because they can often (though not always) set MAC addresses with minimal effort (MAC spoofing). If eavesdroppers have the ability to change their MAC address, then they may join the network by spoofing an authorized address.
Wired Equivalent Privacy (WEP) encryption was designed to protect against casual snooping, but is now deprecated. Tools such as AirSnort or Aircrack-ng can quickly recover WEP encryption keys. Once it has seen 5-10 million encrypted packets, AirSnort can determine the encryption password in under a second; newer tools such as aircrack-ptw can use Klein's attack to crack a WEP key with a 50% success rate using only 40,000 packets.
To counteract this in 2002, the Wi-Fi Alliance approved Wi-Fi Protected Access (WPA) which uses TKIP as a stopgap solution for legacy equipment. Though more secure than WEP, it has outlived its designed lifetime and has known attack vectors.
In 2004, the IEEE ratified the full IEEE 802.11i (WPA2) encryption standards. If used with a 802.1X server or in pre-shared key mode with a strong and uncommon passphrase WPA2 is still considered[by whom?] secure, as of 2009.

Piggybacking
Main article: Piggybacking (Internet access)
Piggybacking refers to access to a wireless Internet connection by bringing one's own computer within the range of another's wireless connection, and using that service without the subscriber's explicit permission or knowledge.
During the early popular adoption of 802.11, providing open access points for anyone within range to use was encouraged[by whom?] to cultivate wireless community networks, particularly since people on average use only a fraction of their downstream bandwidth at any given time.
Recreational logging and mapping of other people's access points has become known as wardriving. Indeed, many access points are intentionally installed without security turned on so that they can be used as a free service. Providing access to one's Internet connection in this fashion may breach the Terms of Service or contract with the ISP. These activities do not result in sanctions in most jurisdictions; however, legislation and case law differ considerably across the world. A proposal to leave graffiti describing available services was called warchalking. A Florida court case determined that owner laziness was not to be a valid excuse.
Piggybacking often occurs unintentionally, most access points are configured without encryption by default, and operating systems can be configured to connect automatically to any available wireless network. A user who happens to start up a laptop in the vicinity of an access point may find the computer has joined the network without any visible indication. Moreover, a user intending to join one network may instead end up on another one if the latter has a stronger signal. In combination with automatic discovery of other network resources (see DHCP and Zeroconf) this could possibly lead wireless users to send sensitive data to the wrong middle-man when seeking a destination (see Man-in-the-middle attack). For example, a user could inadvertently use an insecure network to log in to a website, thereby making the login credentials available to anyone listening, if the website uses an insecure protocol such as HTTP.

Federal Communications Commission


Federal Communications Commission
FCC
US-FCC-Seal.svg

US-FCC-Logo.svg
logo
Agency overview
FormedJune 19, 1934
Preceding agencyFederal Radio Commission
HeadquartersWashington, D.C., United States
Annual budgetUS$352.5 million (FY 2011)
Agency executiveJulius Genachowski, Chairman
Website
www.fcc.gov

The Federal Communications Commission (FCC) is an independent agency of the United States government, created, Congressional statute (see 47 U.S.C. § 151 and 47 U.S.C. § 154), and with the majority of its commissioners appointed by the current President. The FCC works towards six goals in the areas of broadband, competition, the spectrum, the media, public safety and homeland security, and modernizing the FCC.
The FCC was established by the Communications Act of 1934 as the successor to the Federal Radio Commission and is charged with regulating all non-federal government use of the radio spectrum (including radio and television broadcasting), and all interstate telecommunications (wire, satellite and cable) as well as all international communications that originate or terminate in the United States. It is an important factor in U.S. telecommunication policy. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions. Due however to close geographic proximity to the United States, the FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC has a 2009 proposed budget of $466 million which is funded by $1 million in taxpayer appropriations and the rest in regulatory fees. It has 1,899 "full-time equivalent" federal employees.

Mission and strategy

As specified in section one of the Communications Act as amended by the Telecommunications Act of 1996 (amendment to 47 U.S.C. §151) it is the FCC's mission to "make available so far as possible, to all the people of the United States, without discrimination on the basis of race, color, religion, national origin, or sex, rapid, efficient, Nation-wide, and world-wide wire and radio communication services with adequate facilities at reasonable charges." The Act furthermore provides that the FCC was created "for the purpose of the national defense" and "for the purpose of promoting safety of life and property through the use of wire and radio communications."
Consistent with the objectives of the Act as well as the 1993 Government Performance and Results Act (GPRA), the FCC has identified six goals in its 2006-2011 Strategic Plan. These are:
Broadband: "All Americans should have affordable access to robust and reliable broadband products and services. Regulatory policies must promote technological neutrality, competition, investment, and innovation to ensure that broadband service providers have sufficient incentives to develop and offer such products and services."
Competition: "Competition in the provision of communication services, both domestically and overseas, supports the Nation's economy. The competitive framework for communications services should foster innovation and offer consumers reliable, meaningful choice in affordable services."
Spectrum: "Efficient and effective use of non-federal spectrum domestically and internationally promotes the growth and rapid development of innovative and efficient communication technologies and services."
Media: "The Nation's media regulations must promote competition and diversity and facilitate the transition to digital modes of delivery."
Public Safety and Homeland Security: "Communications during emergencies and crisis must be available for public safety, health, defence, and emergency personnel, as well as all consumers in need. The Nation's critical communications infrastructure must be reliable, interoperable, redundant, and rapidly restorable."
Modernize the FCC: "The Commission shall strive to be highly productive, adaptive, and innovative organization that maximises the benefits to stakeholders, staff, and management from effective systems, processes, resources, and organizational culture."

History

Communications Act of 1934
In 1934 Congress passed the Communications Act, which abolished the Federal Radio Commission and transferred jurisdiction over radio licensing to a new Federal Communications Commission, including in it also the telecommunications jurisdiction previously handled by the Interstate Commerce Commission. Title II of the Communications Act focused on telecommunications using many concepts borrowed from railroad legislation and Title III contained provisions very similar to the Radio Act of 1927.
[edit]Report on Chain Broadcasting
In 1940 the Federal Communications Commission issued the "Report on Chain Broadcasting." The major point in the report was the breakup of NBC (National Broadcasting Company), which ultimately led to the creation of ABC (American Broadcasting Company), but there were two other important points. One was network option time, the culprit here being CBS. The report limited the amount of time during the day, and what times the networks may broadcast. Previously a network could demand any time it wanted from an affiliate. The second concerned artist bureaus. The networks served as both agents and employees of artists, which was a conflict of interest the report rectified.

The "Freeze" of 1948
In assigning television stations to various cities after World War II, the FCC found that it placed many stations too close to each other, resulting in interference. At the same time, it became clear that the designated VHF channels, 2 through 13, were inadequate for nationwide television service. As a result, the FCC stopped giving out construction permits for new licenses in October 1948. Most expected this "Freeze" to last six months, but as the allocation of channels to the emerging UHF technology and the eagerly-awaited possibilities of color television were debated, the FCC's re-allocation map of stations did not come until April 1952, with July 1, 1952 as the official beginning of licensing new stations.
The FCC's "Sixth Report & Order" ended the Freeze. It would take five years for the U.S. to grow from 108 stations to more than 550. New stations came on line slowly, only five by the end of November 1952. The Sixth Report and Order required some existing TV stations to change channels, but only a few existing VHF stations were required to move to UHF, and a handful of VHF channels were deleted altogether in smaller media markets like Peoria, Fresno, and Bakersfield to create markets which were UHF "islands." The report also set aside a number of channels for the newly emerging field of educational television, which hindered struggling ABC and DuMont's quest for affiliates in the more desirable markets where VHF channels were reserved for non-commercial use.
The Sixth Report and Order also provided for the "intermixture" of VHF and UHF channels in most markets; UHF transmitters in the 1950s were not yet powerful enough, nor receivers sensitive enough (if they included UHF tuners at all - they were not formally required until the 1960s All-Channel Receiver Act), to make UHF viable against entrenched VHF stations. In markets where there were no VHF stations and UHF was the only TV service available, UHF survived. In other markets, which were too small to financially support a television station, too close to VHF outlets in nearby cities, or where UHF was forced to compete with more than one well-established VHF station, UHF had little chance for success.
Denver had been the largest U.S. city without a TV station by 1952. Senator Edwin Johnson (D-Colorado), chair of the Senate's Interstate and Foreign Commerce Committee, had made getting Denver the first post-Freeze station his personal mission. He had pressured the FCC, and proved ultimately successful as the first new station (a VHF station) came on-line a remarkable ten days after the Commission formally announced the first post-Freeze construction permits. KFEL (now KWGN-TV)'s first regular telecast was on July 21, 1952.

Telephone monopoly to competition
The important relationship of the FCC and the American Telephone and Telegraph (AT&T) Company has evolved over several years. For many years, the FCC and state officials agreed to regulate the telephone systems as a natural monopoly. The FCC controlled telephone rates to limit the profits of AT&T and ensure nondiscriminatory pricing. In the 1960s, the FCC began allowing other long-distance companies, namely MCI, to offer specialized services. In the 1970s, the FCC allowed other companies to expand offerings to the public. A lawsuit in 1982 led by the Justice Department after AT&T underpriced other companies, resulted in the split of the Bells from AT&T. Beginning in 1984, the FCC implemented a new goal that all long-distance companies had equal access to the local phone companies' customers.

Telecommunications Act of 1996
In 1996 Congress enacted the Telecommunications Act of 1996, in the wake of the break-up of AT&T resulting from the U.S. Justice Department's antitrust suit against AT&T. In part, the 1996 legislation attempted to create more competition in local telephone service by requiring Incumbent Local Exchange Carriers to provide access to their facilities for Competitive Local Exchange Carriers.
This policy has thus far had limited success and much criticism. See. e.g. Robert Crandall The development of the Internet, cable services and wireless services has raised questions whether new legislative initiates are needed as to competition in what has come to be called 'broadband' services. Congress has monitored developments but as of 2009 has not undertaken a major revision of applicable regulation. The Local Community Radio Act in the 111th Congress has gotten out of committee and will go before the house floor with bi-partisan support, and unanimous support of the FCC.


Connection permissivity, indecency crackdowns
The inauguration of Ronald Reagan as President of the United States in 1981 accelerated an already ongoing shift in the FCC towards a decidedly more market-oriented stance. A number of regulations felt to be outdated were removed, most controversially the Fairness Doctrine in 1987. The FCC also took steps to increase competition to broadcasters, fostering broadcast alternatives such as cable television. It's worth also noting that in terms of indecency fines, there was not action taken by the FCC from FCC v. Pacifica until 1987, about ten years later.
In the early 2000s, the FCC began stepping up censorship and enforcement of indecency regulations again, most notably following the Janet Jackson "wardrobe malfunction" that occurred during the halftime show of Super Bowl XXXVIII. However, the FCC's regulatory domain with respect to indecency remains restricted to the public airwaves, notably VHF and UHF television and AM/FM radio.
On June 15, 2006, President George W. Bush signed into law the Broadcast Decency Enforcement Act of 2005 sponsored by Senator Sam Brownback, a former broadcaster himself, and endorsed by Congressman Fred Upton of Michigan who authored a similar bill in the United States House of Representatives. The new law stiffens the penalties for each violation of the Act. The Federal Communications Commission will be able to impose fines in the amount of $325,000 for each violation by each station that violates decency standards. The legislation raised the fine tenfold over the previous maximum of $32,500 per violation.

Organization

The FCC is organized into seven Bureaus and eleven Staff Offices.

Bureaus
'The Bureaus' include processing applications for licenses and other filings, analyzing complaints, conducting investigations, developing and implementing regulations, and participating in hearings.
The Consumer & Governmental Affairs (CGB) develops and implements the FCC's consumer policies, including disability access. CGB serves as the public face of the FCC through outreach and education, as well as through their Consumer Center, which is responsible for responding to consumer inquiries and complaints. CGB also maintains collaborative partnerships with state, local, and tribal governments in such areas as emergency preparedness and implementation of new technologies.
The Enforcement Bureau (EB) is responsible for enforcement of provisions of the Communications Act 1934, FCC rules, FCC orders, and terms and conditions of station authorizations. Major areas of enforcement that are handled by the Enforcement Bureau are consumer protection, local competition, public safety, and homeland security.
The International Bureau (IB) develops international policies in telecommunications, such as coordination of frequency allocation and orbital assignments so as to minimize cases of international electromagnetic interference involving U.S. licensees. The International Bureau also oversees FCC compliance with the international Radio Regulations and other international agreements.
The Media Bureau (MB) develops, recommends and administers the policy and licensing programs relating to electronic media, including cable television, broadcast television, and radio in the United States and its territories. The Media Bureau also handles post-licensing matters regarding direct broadcast satellite service.
The Wireless Telecommunications Services (WCS) such as Advanced Wireless Services (AWS) and fixed, mobile, and broadcast services on the 700 MHz Band.
The Wireline Competition Bureau (WCB) develops policy concerning wireline  telecommunications. The Wireline Competition Bureau's main objective is to promote growth and economical investments in wireline technology infrastructure, development, markets, and services.
The Public Safety and Homeland Security Bureau was launched in 2006.

Offices
The FCC's Offices provide support services to the Bureaus. Though the Bureaus and Offices have their individual functions, they regularly work together on FCC issues.
The Office of Administrative Law Judges (OALJ) is responsible for conducting hearings ordered by the Commission. The hearing function includes acting on interlocutory requests filed in the proceedings such as petitions to intervene, petitions to enlarge issues, and contested discovery requests. An Administrative Law Judge, appointed under the Administrative Procedure Act, presides at the hearing during which documents and sworn testimony are received in evidence, and witnesses are cross-examined. At the conclusion of the evidentiary phase of a proceeding, the presiding Administrative Law Judge writes and issues an Initial Decision which may be appealed to the Commission.
The Office of Communications Business Opportunities (OCBO) promotes telecommunications business opportunities for small, minority-owned, and women-owned businesses. OCBO works with entrepreneurs, industry, public interest organizations, individuals, and others to provide information about FCC policies, increase ownership and employment opportunities, foster a diversity of voices and viewpoints over the airwaves, and encourage participation in FCC proceedings.
The Office of Engineering and Technology (OET) advises the Commission concerning engineering matters.
Its chief role is to manage the electromagnetic spectrum, specifically frequency allocation and spectrum usage. OET conducts technical studies of advanced phases of terrestrial and space communications and administers FCC rules regarding radio devices, experimental radio services, and industrial, scientific, and medical equipment.
OET organizes the Technical Advisory Council, a committee of FCC advisors from major telecommunication and media corporations.
OET operates the Equipment Authorization Branch, which has the task of overseeing equipment authorization for all devices using the electromagnetic energy from 9 kHz to 300 GHz. OET maintains an electronic database of all Certified equipment which can be easily accessed by the public.
The Office of General Counsel serves as the chief legal advisor to the Commission. The General Counsel also represents the Commission in litigation in United States federal courts, recommends decisions in adjudicatory matters before the Commission, assists the Commission in its decision making capacity and performs a variety of legal functions regarding internal and other administrative matters.
The Office of the Inspector General (OIG) recommends policies to prevent fraud in agency operations. The Inspector General recommends corrective action where appropriate, referring criminal matters to the United States Department of Justice for potential prosecution.
The Office of Legislative Affairs (OLA) is the FCC's liaison to the United States Congress, providing lawmakers with information about FCC regulations. OLA also prepares FCC witnesses for Congressional hearings, and helps create FCC responses to legislative proposals and Congressional inquiries. In addition, OLA is a liaison to other Federal agencies, as well as state and local governments.
The Office of the Managing Director (OMD) is responsible for the administration and management of the FCC, including the agency's budget, personnel, security, contracts, and publications.
The Office of Media Relations (OMR) is responsible for the dissemination of Commission announcements, orders, proceedings, and other information per media requests. OMR manages the FCC Daily Digest, website, and Audio Visual Center.
The Office of the Secretary (OSEC) oversees the receipt and distribution of documents filed by the public through electronic and paper filing systems and the FCC Library collection. In addition, OSEC publishes legal notices of Commission decisions in the Federal Register and the FCC Record.
The Office of Strategic Planning & Policy Analysis (OSP), essentially a think tank within the FCC, identifies policy objectives for the agency. OSP works closely with the FCC Chairman and is responsible for monitoring the state of the communications industry to identify trends, issues and overall industry health. OSP acts as expert consultants to the Commission in areas of economic, business, and market analysis. The Office also reviews legal trends and developments not necessarily related to current FCC proceedings, such as intellectual property law, the Internet, and electronic commerce. Previously OSP was called the Office of Plans and Policy (OPP). Catherine Bohigian has been the chief of the OSP since 2005.
The Office of Workplace Diversity (OWD) develops policy to provide a full and fair opportunity for all employees, regardless of non-merit factors such as race, religion, gender, color, age, disability, sexual orientation or national origin, to carry out their duties in the workplace free from unlawful discriminatory treatment, including sexual harassment and retaliation for engaging in legally protected activities.

Broadcast licensing



An additional logo
As a regulator of over-the-air broadcast station s, FCC has one major regulatory instrument, revoking broadcast licenses, but short of that has limited leverage except for fines. (see FCC MB Docket 04-232). Sanctions run a report-basis system. Additionally, broadcast licenses are to be renewed if the station meets the "public interest, convenience, or necessity". However, the Federal Communications Commission now rarely checks except for some obvious and outstanding reason; the burden of proof would be on the complainant in a petition to deny. Fewer than 1% of station renewals are not immediately granted, and only a small fraction of those are ultimately denied.
The Federal Communications Commission also licenses amateur radio operators and repeater stations, and does use its power to fine amateur radio operators who flagrantly violate its rules. It also licenses commercial operators who operate and repair certain radiotelephone, television, radar, and Morse code radio stations. In recent years it has also licensed people who maintain or operate GMDSS stations. While the FCC maintains control of the written and Morse testing standards, it no longer administers the exams, having delegated that function to private organizations.
The FCC has been criticized for awarding a digital TV (DTV) channel to each holder of an analog TV station license without an auction, as well as trading auctionable spectrum to Nextel to resolve public safety RF interference problems. Conversely, it has also been criticized for forcing stations to buy and install all new equipment (transmitters, TV antennas, and even entirely new broadcast towers), and operate for years on both channels at once. This was at great expense to every TV station, and without government compensation for the regulatory taking, despite 20 billion dollars brought in by taking more than 25% of the TV broadcast band (and the part most valuable for mobile TV, the future of broadcasting) away and auctioning it. On June 12, 2009, all full-power analog terrestrial TV licenses in the U.S. were terminated, with terrestrial television subsequently available only from the digital channels and a few low-power LPTV stations, leaving stations and the viewing public with millions of dollars in useless analog equipment, and with a reduced audience that could not or would not get the necessary DTV converter boxes. See DTV transition in the United States.

Controversies

Unreleased reports

2003 study of commercial radio concentration
In 2003, the FCC Media Bureau produced a draft report analyzing the impact of deregulation in the radio industry.The report stated that from March 1996 through March 2003, the number of commercial radio stations on the air rose 5.9 percent while the number of station owners fell 35 percent. The concentration of ownership followed a 1996 rewrite of telecommunications law that eliminated a 40-station national ownership cap.
The report was never made public, nor have any similar analyses followed, despite the fact that radio industry reports were released in 1998, 2001 and 2002. In September 2006, Senator Barbara Boxer, who had received a copy of the report, released it.

2004 study of television media concentration
In 2004, the FCC ordered its staff to destroy all copies of a draft study by Keith Brown and Peter Alexander, two economists in the FCC's Media Bureau. The two had analyzed a database of 4,078 individual news stories broadcast in 1998, showed local ownership of television stations adds almost five and one-half minutes of total news to broadcasts and more than three minutes of "on-location" news.
The conclusion of the study was at odds with FCC arguments made when it voted in 2003 to increase the number of television stations a company could own in a single market. (In June 2004, a federal appeals court rejected the agency's reasoning on most of the rules and ordered it to try again.)
In September 2006, Senator Barbara Boxer, who had received a copy of the report "indirectly from someone within the FCC who believed the information should be made public," wrote a letter to FCC Chairman Kevin Martin, asked whether any other commissioners "past or present" knew of the report's existence and why it was never made public. She also asked whether it was "shelved because the outcome was not to the liking of some of the commissioners and/or any outside powerful interests?" Boxer's office said if she does not receive adequate answers to her questions, she will push for an investigation by the FCC inspector general.

Action by FCC Chairman
In a letter in response to Senator Boxer, FCC Chairman Martin said "I want to assure you that I too am concerned about what happened to these two draft reports." The letter also said "I have asked the inspector general of the FCC to conduct an investigation into what happened to these draft documents and will cooperate fully with him." Martin added that he was not chairman at the time the reports were drafted, and that neither he nor his staff had seen them.

NSA wiretapping
When it emerged in 2006 that AT&T, BellSouth and Verizon may have broken U.S. laws by aiding the National Security Agency in possible illegal wiretapping of its customers, Congressional representatives called for an FCC investigation into whether or not those companies broke the law. The FCC declined to investigate, however, claiming that it could not investigate due to the classified nature of the program– a move that provoked the criticism of members of Congress.
"Today the watchdog agency that oversees the country's telecommunications industry refused to investigate the nation's largest phone companies' reported disclosure of phone records to the NSA," said Rep. Edward Markey (D-Mass.) in response to the decision. "The FCC, which oversees the protection of consumer privacy under the Communications Act of 1934, has taken a pass at investigating what is estimated to be the nation's largest violation of consumer privacy ever to occur. If the oversight body that monitors our nation's communications is stepping aside then Congress must step in."

Diversity
With the major demographic shifts occurring in the country in terms of the racial-ethnic composition of the population, the FCC has also been criticized for ignoring the issue of decreasing racial-ethnic diversity of the media. This includes charges that the FCC has been watering down the limited affirmative action regulations it had on the books, including no longer requiring stations to make public their data on their minority staffing and hiring. In the second half of 2006, groups such as the National Hispanic Media Coalition, the National Latino Media Council, the National Association of Hispanic Journalists, the National Institute for Latino Policy, the League of United Latin American Citizens (LULAC) and others held town hall meetings in California, New York and Texas on media diversity as its affects Latinos and minority communities. They documented widespread and deeply-felt community concerns about the negative effects of media concentration and consolidation on racial-ethnic diversity in staffing and programming. See El Diario La Prensa's editorial on media diversity. At these Latino town hall meetings, the issue of the FCC's lax monitoring of obscene and pornographic material in Spanish-language radio and the lack of racial and national-origin diversity among Latino staff in Spanish-language television were other major themes. President Obama appointed Mark Lloyd to the FCC in the newly created post of Associate General Counsel/Chief Diversity Officer.

Use of white space
On October 15, 2008, FCC Chairman Kevin Martin announced his support for the use of white spaces within the radio frequency spectrum. White spaces are airwaves that will go unused after the federally mandated transformation of analog TV signal to digital. He said he is "hoping to take advantage of utilizing these airwaves for broadband services to allow for unlicensed technologies and new innovations in that space." While technology innovators such as Google and Microsoft are vying for the use of this white-space to support innovation in Wi-Fi technology, broadcasters and wireless microphone manufacturers fear that the use of white-space would "disrupt their broadcasts and the signals used in sports events and concerts." Cell phone providers such as T-Mobile USA have mounted pressure on the FCC to instead offer up the white-space for sale to boost competition and market leverage.
On November 4, 2008, the FCC unanimously agreed to open up unused broadcast TV spectrum for unlicensed use.

Network neutrality
Main article: Network neutrality in the United States
The FCC has claimed some jurisdiction over the issue of network neutrality (see Network neutrality in the United States) and has laid down guideline rules that it expects the telecommunications industry to follow. On February 11, 2008 Rep. Ed Markey and Rep. Chip Pickering introduced HR5353 "To establish broadband policy and direct the Federal Communications Commission to conduct a proceeding and public broadband summit to assess competition, consumer protection, and consumer choice issues relating to broadband Internet access services, and for other purposes." On 1 August 2008 the FCC formally voted 3-to-2 to upholding a complaint against Comcast, the largest cable company in the US, ruling that it had illegally inhibited users of its high-speed Internet service from using file-sharing software. The FCC imposed no fine, but required Comcast to end such blocking in 2008. FCC chairman Kevin J. Martin said the order was meant to set a precedent that Internet providers, and indeed all communications companies, could not prevent customers from using their networks the way they see fit unless there is a good reason. In an interview Martin stated that "We are preserving the open character of the Internet" and "We are saying that network operators can't block people from getting access to any content and any applications." Martin's successor, Julius Genachowski has maintained that the FCC has no plans to regulate the internet, saying: "I've been clear repeatedly that we're not going to regulate the Internet." The Comcast case highlighted broader issues of whether new legislation is needed to force Internet providers to maintain network neutrality, i.e. treat all uses of their networks equally. The legal complaint against Comcast related to BitTorrent, software that is commonly used for downloading larger files.

Proprietary standards
The FCC has also been criticized for ignoring international open standards, and instead choosing proprietary closed standards, or allowing communications companies to do so and implement the anticompetitive practice of vendor lock-in, thereby preventing a free market.
In the case of digital TV, it chose the ATSC standard, even though DVB was already in use around the world, including DVB-S satellite TV in the U.S. Unlike competing standards, the ATSC system is encumbered by numerous patents, and therefore royalties that make TV sets and DTV converters much more expensive than in the rest of the world. Additionally, the claimed benefit of better reception in rural areas is more than negated in urban areas by multipath interference, which other systems are nearly immune to. It also cannot be received while in motion for this reason, while all other systems can, even without dedicated mobile TV signals or receivers.
For digital radio, the FCC chose proprietary HD Radio, which crowds the existing FM broadcast band and even AM broadcast band with in-band adjacent-channel sidebands, which create noise in other stations. This is in contrast to worldwide DAB, which uses unused TV channels in the VHF band III range. This too has patent fees, while DAB does not. Enormous expense is involved in converting each station, largely from these fees, and so it is completely prohibitive for community radio and most other non-commercial educational stations.
Satellite radio (also called SDARS by the FCC) uses two proprietary standards instead of DAB-S, which requires users to change equipment when switching from one provider to the other, and prevents other competitors from offering new choices as stations can do on terrestrial radio. Had the FCC picked DAB-T for terrestrial radio, no separate satellite receiver would have been needed at all, and the only difference from DAB receivers in the rest of the world would be in software, where it would need to tune S band instead of L band.
In mobile telephony, the FCC abandoned the "any lawful device" principle decided against AT&T landlines, and has instead allowed each mobile phone company to dictate what its customers can use.

Local broadcasting
After being successful in opening the FM band as a superior alternative to the AM band by allowing colleges and other schools to start ten-watt LPFM stations, the FCC banned new ones around 1980, at the behest of the powerful commercial radio stations of the National Association of Broadcasters, and the then-new National Public Radio. The exception to the ban is for NAB/NPR member stations (and now religious radio) to construct broadcast translators, which raises issues about equal protection of free speech, because it bans technically-identical stations just for originating their own programming. Commercial station groups are now also using "translator" stations to circumvent caps on local media ownership, be feeding them a signal that is also broadcast on an AM station or "HD" channel that cannot otherwise be heard.
The concept of the city of license has also become a nearly meaningless legal fiction over the years, as stations no longer have any requirement to air any local content.

FCC broadcasting tower database

The FCC database of broadcasting towers provides information about the height and year built of broadcasting towers in the USA. It does not contain information about the structural types of towers or about the height of towers used for non-broadcasting purposes like NDBs, LORAN-C transmission towers or VLF transmission facilities of the US Navy, or about towers not used for transmission like the BREN Tower. These are instead tracked by the Federal Aviation Administration as obstructions to air navigation.

FCC commissioners

The FCC is directed by five commissioners appointed by the U.S. president and confirmed by the U.S. Senate for five-year terms, except when filling an unexpired term. The president designates one of the commissioners to serve as chairperson. Only three commissioners may be members of the same political party. None of them may have a financial interest in any FCC-related business.

Current chairman and commissioners

Headquarters

The FCC leases space in the Portals building in southwest Washington, DC. Construction of the Portals building was scheduled to begin on March 1, 1996. In January 1996 the General Services Administration signed a lease with the building's owners, agreeing to let the FCC lease 450,000 square feet (42,000 m2) of space in Portals for 20 years, at a cost of $17.3 million per year in 1996 dollars. Prior to its current arrangement, the FCC had space in six buildings by 19th Street NW and M Street NW. The FCC first solicited bids for a new headquarters complex in 1989. In 1991 the GSA selected the Portals site. The FCC had wanted to move into a more expensive area along Pennsylvania Avenue.
