Frequency bands suitable for satellite communications
ITU defines frequency bands, which are used for satellite communications.UHF (Ultra High Frequency) or decimeter wave frequency band, the frequency range is 300MHz-3GHz.This frequency band corresponds to IEEE UHF (300MHz-1GHz), L (1-2GHz), and S (2-4GHz) frequency bands.UHF frequency band radio waves are close to the line-of-sight propagation, easily blocked by mountains and buildings, etc., and i……
