M band
}} M band can refer to two different regions of the electromagnetic spectrum, in the radio and near-infrared. ==Radio== The NATO M band is the range of radio frequencies from 60 GHz to 100 GHz in the system of letter designations for frequency bands used by NATO for electronic countermeasure (ECM) applications. This is equivalent to wavelengths between 5 mm and 3 mm. The NATO M band is a subset of the EHF band as defined by the ITU. The NATO M band intersects with the V (50–75 GHz) and W band (75–110 GHz) of the older IEEE classification system.
