The 800 MHz frequency band is a portion of the electromagnetic spectrum, or frequency band, that encompasses 790–862 MHz.. Being a part of the spectrum known as "UHF Bands IV and V" (i.e. 470 MHz to 862 MHz) it was allocated by the ITU to Broadcasting as the primary user in Region 1 and was used for analogue television broadcasting before changing to digital terrestrial television in many ...
In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.
In the United States, FM broadcasting stations currently are assigned to 101 channels, designated 87.9 to 107.9 MHz, within a 20.2 MHz-wide frequency band, spanning 87.8–108.0 MHz. In the 1930s investigations were begun into establishing radio stations transmitting on "Very High Frequency" (VHF) assignments above 30 MHz.
“We have been discussing adopting 800-MHz radios since at least 2008, so that makes 16 years at a minimum.” ... Hillsdale County voters to decide on 800-MHz radio needs Aug. 6. Show comments ...
In 2004 the FCC developed a new band plan where narrowband operations are provided in 806–816 and 851–861 MHz ranges while wideband operations are allowed in 817–824 MHz and 862–869 MHz separated from narrowband services by a 1 MHz wide guard band. [6] The wideband services part of the SMR band was called ESMR (Enhanced SMR).
The Michigan State Police already operate on the 800 MHz band and the Hillsdale County Sheriff’s Office received funding from the state to make the transition already.
With the Federal Communications Commission's pending release of the first 800 MHz [note 1] band licenses, the LEAA funded a project to develop required capabilities and standards needed in trunked public safety two-way radio systems. The report defined proposed methods for frequency reuse, coordination, and interference reduction. [2]
Class R: VHF, 100 kW low-band (channels 2–6), 325 kW high-band. (channels 7-13) Class S: VHF, more than 100 kW low-band/325 kW high-band. Notes: Official definitions of these classes are difficult to locate. The values above are inferred from the Industry Canada database. There is some ambiguity about the difference between Classes C and D.
