L band
L band (20-cm radar long-band) is a portion of the microwave band of the electromagnetic spectrum ranging roughly from 0.39 to 1.55 GHz. It is used by some communications satellites, and by terrestrial Eureka 147 digital audio broadcasting. In the U.S., the L band is held by the U.S. Military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions. DAB is typically done in the 1452–1492-MHz range as in Canada, but other countries also use VHF and UHF bands.
The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.
The different NATO "L band" is defined as frequency band between 40–60 GHz (5–7.5 mm).
