Review of the 88 Expanded Band authorizations made by the Federal Communications Commission on March 17, 1997. [5] In the table below: For the "Original Standard Band Assignment" entries, the FCC's March 17, 1997 notification listed station's call signs and frequencies as of June 30, 1993, dating to when the stations initially notified the commission that they were interested in participating.
LMR Narrowbanding is the result of an FCC Order issued in December 2004 [3] mandating that all CFR 47 Part 90 business, educational, industrial, public safety, and state and local government [4] VHF (150-174 MHz) and UHF (421-470 MHz) Private Land Mobile Radio (PLMR) licensees operating legacy wideband (25 kHz bandwidth) voice or data/SCADA systems to migrate to narrowband (12.5 kHz bandwidth ...
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...
Unlicensed Personal Communications Services or UPCS band is the 1920–1930 MHz frequency band allocated by the United States Federal Communications Commission (FCC) for short range Personal Communications Services (PCS) applications in the United States, such as the Digital Enhanced Cordless Telecommunications (DECT) wireless protocol.
In 2007, the FCC began requiring that devices operating in channels 52, 56, 60 and 64 must have Dynamic Frequency Selection (DFS) capabilities. This is to avoid communicating in the same frequency range as some radar. In 2014, the FCC issued new rules [10] for all devices due to interference with government weather radar systems. Fines and ...
The FCC is also responsible for reallocating bands of frequencies to different allocations. As new technologies develop the demand for frequency bands changes and makes some bands more desirable than previously. [8] When this occurs, the FCC may make a decision to move an application to a different band of spectrum to make room for something else.
In 1986, the FCC allocated an additional 5 MHz of spectrum for each channel block, raising the total amount of spectrum per block to the current total of 25 MHz. [3] The wireline/non-wireline distinction for Cellular Service licensees no longer exists. The 1850–1990 MHz PCS band is divided into six frequency blocks (A through F). Each block ...
Class A power was doubled to six kilowatts, and the frequency restrictions noted above were removed. As of late 2004, a station can be "squeezed in" anywhere as long as the location and class conform to the rules in the FCC separation table. [4] The rules for second-adjacent-channel spacing do not apply for stations licensed before 1964.
