The attenuation by heavy rain and snow sometimes results in outage of the radio communications at the SHF frequency band and above. g. around 12 GHz. Taking the above properties into account, different portions of the radio spectrum are better suited to different purposes. A radio spectrum channel has a bandwidth giving the width of the range of frequencies on which an information signal travels. A broader bandwidth is required in order to convey higher data rate information. This suggests that the higher frequency bands in the spectrum are more suitable for broadband communications.
The UHF band is used for TV broadcast services. It is also used for two-way communication systems, including cellular radio systems and TErrestrial Trunked RAdio (TETRA) systems, known as walkie-talkies. The band is also used for fixed wireless links and medium-range radars. The UHF band has a relatively short wavelength compared to VHF or lower bands. This leads to smaller sizes of antenna and transceiver device. Since the UHF radio waves can go through the ionosphere, the satellite communication systems also use this band, including the Global Positioning System (GPS) and mobile satellite systems.
