North Atlantic Treaty Organisation - this page is a stub

The North Atlantic Treaty Organization (NATO) — French: Organisation du traité de l'Atlantique nord (OTAN) — also known as North Atlantic Alliance, is an intergovernmental military alliance between 30 North American and European countries. The organisation implements the North Atlantic Treaty – signed on 4 April 1949 – and has its headquarters in Evere (Brussels, Belgium), whilst the headquarters of the Allied Command Operations (SHAPE) is near Mons (Belgium) [1]. It is the successor to the Western Union (WU), also known as Brussels Treaty Organisation (BTO) [3].

Within NATO, there are several ways to identify a specific frequency band, some of which stem from the Cold War era. Although these band designators are now obsolete, they are still used in practice. Below are some of the designator systems used by NATO. In addition, regular ITU band designators like HF, VHF and UHF are also used, as are IEEE band designators.


Band Frequency Remark
A 0 - 250 MHz VLF, LF, MF, HF, VHF — fixed/mobile comms, navigation
B 250 - 500 MHz VHF, UHF — fixed/mobile comms, satellite, meteo, nav.
C 500 - 1000 MHz UHF — fixed/mobile comms, radiolocation
D 1 - 2 GHz UHF — aeronautical comms, radio navigation, satellite
E 2 - 3 GHz UHF — fixed/mobile comms, radiolocation, nav. satellite
F 3 - 4 GHz SHF — radiolocation
G 4 - 6 GHz SHF — fixed/mobile comms, radiolocation
H 6 - 8 GHz SHF — fixed/mobile satellite
I 8 - 10 GHz SHF — radiolocation
J 10 - 20 GHz SHF — fixed/mobile comms, radiolocation
K 20 - 40 GHz SHF, EHF — fixed/mobile satellite, radiolocation
L 40 - 60 GHz EHF — fixed/mobile satellite, radiolocation
M 60 - 100 GHz EHF — fixed/mobile satellite, radiolocation
N 100 - 200 GHz US Military / SACLANT

  1. 225 - 400 MHz
  2. 610 - 960 MHz
  3. 1350 - 1850 MHz
  4. 1350 - 2700 MHz
  5. 4400 - 5000 MHz
