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 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 ...
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.
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (most recent version, Edition of 2020). [2]In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is within the responsibility of the ...
