The NATO D band is the obsolete designation given to the radio frequencies from 1.0 to 2.0 GHz (equivalent to wavelengths between 30 and 15 cm) during the cold war period. Since 1992, frequency allocations, allotment and assignments are in line with the NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crisis management planning, training, electronic warfare activities, or in military operations, this system is still in use.
