Ultra High Frequency
Full Form of UHF
What is UHF?
UHF, or Ultra High Frequency, refers to the radio frequency band ranging from 300 megahertz to 3 gigahertz, which sits between the VHF and SHF bands in the electromagnetic spectrum. In India, UHF plays a vital role in terrestrial television broadcasting, with Doordarshan and several private channels transmitting signals on this band. It is extensively used by mobile network operators for 4G LTE services, by police and security forces for walkie-talkie communication, and by aviation authorities for certain navigational aids. The Indian Navy and Air Force also rely on UHF equipment for tactical communications across border regions. UHF signals travel well in urban environments, penetrating buildings and obstacles more effectively than higher frequency bands, which makes them ideal for densely populated Indian cities such as Mumbai, Delhi, and Kolkata. Cable TV operators and DTH service providers depend on UHF frequencies to deliver content to millions of households across the country. The band is regulated by the Wireless Planning and Coordination Wing of the Department of Telecommunications. Students preparing for competitive exams like JEE, NEET, or UPSC often come across questions on the electromagnetic spectrum, including UHF characteristics and applications, in the physics and general science sections.
