UHF Band

The IEEE UHF band, or Ultra High Frequency band, refers to a segment of the radio frequency spectrum that ranges from 300 MHz to 3 GHz. This band is widely utilised for various forms of communication, including television broadcasting, mobile phones, satellite communication, and Wi-Fi. Due to its higher frequency, the UHF band allows for the transmission of large amounts of data over relatively short distances, making it ideal for urban environments where signal penetration through buildings is essential. In Australia, the UHF band is particularly significant for television broadcasting, with channels typically allocated within the 470-820 MHz range. Additionally, UHF frequencies are used for two-way radios, such as those employed by emergency services and other professional communication systems. The propagation characteristics of UHF signals, which include a shorter wavelength, enable better performance in densely populated areas, although they are more susceptible to obstacles and may require line-of-sight for optimal transmission.
