The NATO M band is the obsolete designation given to the radio frequencies from 60 to 100 GHz (equivalent to wavelengths 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). [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.

The NATO M band is also a subset of the EHF band as defined by the ITU. [2] It intersects with the V (50–75 GHz) and W band (75–110 GHz) of the older IEEE classification system. [3]

Frequency allocation

Frequency allocation is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, which is 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) at 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks.

The radio spectrum is the part of the electromagnetic spectrum with frequencies from 30 Hz to 300 GHz. Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio waves is strictly regulated by national laws, coordinated by an international body, the International Telecommunication Union (ITU).

Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band, and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmW or mmWave. Millimetre-length electromagnetic waves were first investigated by Bengali Indian physicist Jagadish Chandra Bose during 1894–1896, when he reached up to 60 GHz in his experiments.

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, Electronic warfare activities, or in military operations, this system is still in use.

The NATO B band is the obsolete designation given to the radio frequencies from 250 to 500 MHz during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).

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, Electronic warfare 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, Electronic warfare activities, or in military operations, this system is still in use.

The Q band is a range of frequencies contained in the microwave region of the electromagnetic spectrum. Common usage places this range between 33 and 50 GHz, but may vary depending on the source using the term. The foregoing range corresponds to the recommended frequency band of operation of WR22 waveguides. These frequencies are equivalent to wavelengths between 6 mm and 9.1 mm in air/vacuum. The Q band is in the EHF range of the radio spectrum.

Aeronautical mobile (OR) service

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 L band is the obsolete designation given to the radio frequencies from 40 to 60 GHz during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).

The NATO E band is a designation given to the radio frequencies from 2 000 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, Electronic warfare 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 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.

NATO Joint Civil/Military Frequency Agreement

NATO Joint Civil/Military Frequency Agreement (NJFA) and is the universal NATO common civil/military treaty to regulate the military access to the radio frequency spectrum in the range of 14 kHz to 100 GHz in peacetime, during exercises, in times of crisis, and in military operations. This document has been the basis for the frequency utilisation in NATO-Europe since 1982. Nations and organisations, e.g. partnership for peace countries, are invited to participate as deemed to be necessary.

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.
