NATO G band

The G band in the modern (NATO/EU) sense is the range of radio frequencies from 4 GHz to 6 GHz in the electromagnetic spectrum. This is equal to wave lengths between 7.5 cm and 5 cm. The G band is in the SHF range of the radio spectrum.

The G band is in the C band of the older classification system.

IEEE G band

The modern IEEE G band covers frequencies from 110 to 300 GHz (2.7 mm—1.0 mm) and includes the 118 GHz oxygen and 183 GHz water lines used for atmospheric sounding. It is also referred to as mm in the 1984 IEEE Standard for Letter Designations for Radar-Frequency Bands.

Obsolete IEEE G band

With the older system, the G band covers frequencies from 140 to 220 MHz (1.5 m—1.2 m) and is in the modern A band.
