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 1and was used for analogue television broadcasting before changing to digital terrestrial television in many countries. As such it is also referred to as "digital dividend" spectrum. In Europe and to some extent elsewhere, the band corresponds to UHF channel 61–69. In most territories the band was also used by Services Ancillary to Broadcasting (SAB) or Services Ancillary to Programme Making (SAP), both often now referred to as PMSE (Programme Making and Special Events) in the form of professional wireless microphones, radio talkback systems and wireless monitor systems.
The European Parliament approved May 2010, At Japan on 2012, the change of use of the 800 MHz band making it available for purposes other than broadcasting (television) – e.g. mobile broadband.
From the year 2013 the 800 MHz band can be used to deliver wireless broadband services, inEurope.
