Frequency allocation is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation of RF bands and their standardization.
The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) as 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks.
HAVE QUICK is an ECM-resistant frequency-hopping system used to protect military aeronautical mobile (OR) radio traffic.
The NATO A band is the obsolete designation given to the radio frequencies from 0 to 250 MHz during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement. However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electromagnetic Warfare (EW) activities, or in military operations, this system is still in use.
The NATO I band is the obsolete designation given to the radio frequencies from 8 000 to 10 000 MHz 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, Electromagnetic Warfare (EW) activities, or in military operations, this system is still in use.
The NATO F band is the obsolete designation given to the radio frequencies from 3 000 to 4 000 MHz 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, Electromagnetic Warfare (EW) activities, or in military operations, this system is still in use.
The NATO M band is the obsolete designation given to the radio frequencies from 60 to 100 GHz during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).
Land mobile service is – in line to ITU Radio Regulations – a mobile service between base stations and land mobile stations, or between land mobile stations.
Mobile service is – in line to ITU Radio Regulations – a radiocommunication service between mobile and land stations, or between mobile stations (CV).
In telecommunications, a fixed service is a radiocommunication service between specified fixed points.
Aeronautical mobile service is – according to Article 1.32 of the International Telecommunication Union's (ITU) Radio Regulations (RR) – defined as "A mobile service between aeronautical stations and aircraft stations, or between aircraft stations, in which survival craft stations may participate; emergency position-indicating radiobeacon stations may also participate in this service on designated distress and emergency frequencies."
Aeronautical mobile (OR) service is – according to Article 1.34 of the International Telecommunication Union's (ITU) Radio Regulations (RR) – defined as "An aeronautical mobile service intended for communications, including those relating to flight coordination, primarily outside national or international civil air routes".
The NATO C-band is the obsolete designation given to the radio frequencies from 500 to 1000 MHz 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, Electromagnetic Warfare (EW) activities, or in military operations, this system is still in use.
The NATO D band is the obsolete designation given to the radio frequencies from 1.0 to 2.0 GHz 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, Electromagnetic Warfare (EW) activities, or in military operations, this system is still in use.
The NATO E band is a designation given to the radio frequencies from 2000 to 3 000 MHz during the cold war period. Since 1992 detailed frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to generically identify military radio spectrum requirements, e.g. for crises management planning, training, Electromagnetic Warfare (EW) activities, radar or in military operations, the Nato band system is often used.
The NATO G band is the obsolete designation given to the radio frequencies from 4 000 to 6 000 MHz 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 H band is the obsolete designation given to the radio frequencies from 6 000 to 8 000 MHz 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 J band is the designation given to the radio frequencies from 10 to 20 GHz. 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 K band is the obsolete designation given to the radio frequencies from 20 to 40 GHz 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 N band is the designation given to the radio frequencies from 100 to 200 GHz used by US armed forces and SACLANT in ITU Region 2.
