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 ...
Further GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983. In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the "1900 MHz band".
Many GSM phones support three bands (900/1,800/1,900 MHz or 850/1,800/1,900 MHz) or four bands (850/900/1,800/1,900 MHz), and are usually referred to as tri-band and quad-band phones, or world phones; with such a phone one can travel internationally and use the same handset. This portability is not as extensive with IS-95 phones, however, as IS ...
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).

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]
