Channel Sharing Agreement
In telecommunications, frequency sharing or channel sharing is the assignment to or use of the same radio frequency by two or more stations that are separated geographically or that use the frequency at different times. It reduces the potential for mutual interference where the assignment of different frequencies to each user is not practical or possible. Channel sharing in digital television U.S. mobile data usage in 2017 was 40 times that in 2010, forcing frequencies to be reallocated. The FCC's 2016 auction allowed two or more stations to share a single 6 MHz television channel while retaining their licenses and all rights. NBC sold the spectrum of three of its stations in the 2017 FCC auction: WNBC WNBC (channel 4) is a television station in New York City that serves as the flagship (broadcasting), flagship of the NBC network.

Telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.

Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies that humans can hear (though these are not electromagnetic) and the lower limit of infrared frequencies, and also encompasses the microwave range. These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conduct ...

User (telecommunications)
In telecommunications, a user is a person, organization, or other entity that uses the services provided by a telecommunication system, or by an information processing system, for transfer of information. A user functions as a source or final destination of user information, or both. A user ''may'' also be the subscriber, i.e. the customer paying for the service. User is also a person or process accessing an AIS by direct connections (e.g., via terminals) or indirect connections. "Indirect connection" relates to persons who prepare input data or receive output that is not reviewed for content or classification by a responsible individual. See also * User (computing) A user is a person who uses a computer or network service. A user often has a user account and is identified to the system by a username (or user name). Some software products provide services to other systems and have no direct end u ... References * {{FS1037C MS188 * National Information Syst ...

2016 United States Wireless Spectrum Auction
The 2016 United States wireless spectrum auction, officially known as Auction 1001, allocated approximately 100 MHz of the United States Ultra High Frequency (UHF) spectrum formerly allocated to UHF television in the 600 MHz band. The spectrum auction and subsequent reallocations were authorized by Title VI (The Spectrum Act) of the payroll tax cut extension passed by the United States Congress on February 17, 2012. Background The 2008 United States wireless spectrum auction, dealing with allocations for UHF television in the 700 MHz band, generated $19.6 billion from companies such as AT&T and Verizon Communications. This auction re-allocated the UHF space formerly occupied by channels 52–69, after the completion of the primary digital television transition in the United States from NTSC to ATSC in 2009. In effect, the digital transition had eliminated 25% of the space allocated for UHF television in the United States. Wireless broadband internet access intere ...
