The NATO I band is the obsolete designation given to the radio frequencies from 8,000 to 10,000 MHz (equivalent to wavelengths between 3.75 and 3 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).[1]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.
