Read moreWhat is the radio spectrum used for?
Radio spectrum is used to carry information wirelessly for a vast number of everyday services ranging from television and radio broadcasting, mobile phones and Wi-Fi to communications systems for the emergency services, baby monitors, GPS and radar.
Read moreWhat is frequency spectrum in communication system?
Frequency spectrum of a signal is the range of frequencies contained by a signal .
Read moreWhy radio frequency is used in communication?
They can easily cover obstacles in their path and reach their destination due to the large wavelength of the signals . Nowadays, radio communication is used in multiple applications and several fields, including military and commercial use of the radio spectrum.
Read moreWhat radio frequency is used in radio communication?
Frequency bandwidths also are allocated, ranging from 300 hertz for radiotelegraphs to 10 kilohertz for voice-grade radiotelephones to more than 500 megahertz for multichannel digital radio relays in the telephone network to about 850 megahertz for cellular telephones .
Read moreWhat is ultra high frequency band?
UHF, abbreviation of ultrahigh frequency, conventionally defined portion of the electromagnetic spectrum, encompassing radiations having a wavelength between 0.1 and 1 m and a frequency between 3,000 and 300 megahertz . UHF signals are used extensively in televison broadcasting.
Read moreWhat devices use very high frequency?
Relevant high-frequency devices include modern computer processors, microwave devices based on magnetization dynamics , and mechanically resonant nanoscale systems. Effectively, these devices take a signal in, process or modify it, and send the signal out.
