N band (NATO)

Not to be confused with N band, in infrared astronomy.

NATO N band

Frequency range	100–200 GHz
Wavelength range	3–1.5 mm
Related bands	V / W (IEEE) EHF (ITU)

The NATO N band is the designation given to the radio frequencies from 100 to 200 GHz (equivalent to wavelengths between 3 mm and 1.5 mm) used by US armed forces and SACLANT in ITU Region 2.

The NATO N band is also a subset of the EHF band as defined by the ITU.

Particularities

The NATO N band is not subject to the NATO Joint Civil/Military Frequency Agreement (NJFA). However, military requirement, which may apply to the NATO operations in ITU Region 1, are subject to coordination with the appropriate frequency administration concerned.
