wavelength
In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats.
In other words, it is the distance between consecutive corresponding points of the same ''phase (waves ...
s 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).
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.
It intersects with the
V (50–75 GHz) and
W band (75–110 GHz) of the older
