L band (NATO)

From Wikipedia, the free encyclopedia

Not to be confused withL band (IEEE).

NATO L band
Frequency range	40–60GHz
Wavelength range	7.5–5mm
Related bands	K / V band (IEEE) SHF / EHF (ITU)

TheNATO L band is the obsolete designation given to theradio frequencies from 40 to 60GHz (equivalent towavelengths between 7.5 and 5 mm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line toNATO 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.
