M band (NATO)

"M band" redirects here. For other uses, see M band (disambiguation).

NATO M band

Frequency range	60–100 GHz
Wavelength range	5–3 mm
Related bands	V / W (IEEE) EHF (ITU)

The NATO M band is the obsolete designation given to the radio frequencies from 60 to 100 GHz (equivalent to wavelengths between 5 and 3 mm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).[1]

However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare activities, or in military operations, this system is still in use.

The NATO M band is also a subset of the EHF band as defined by the ITU.[2] It intersects with the V (50–75 GHz) and W band (75–110 GHz) of the older IEEE classification system.[3]
