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 HF frequency used for?
The band is used by international shortwave broadcasting stations (2.310 – 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services , among other uses.
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 low frequency used for?
The Low Frequency (LF) band is mostly used for AM broadcasting in Europe as well as in areas of Northern Africa and Asia . Similar to VLF, LF can also be used for navigational radio beacons. It can also be used for maritime ship-to-shore communication, as well as transoceanic air traffic control.
Read moreWhy do we use higher frequency?
Increasing the frequencies will give everyone more “room” to transmit radiowaves . Increasing data rates, because having a higher carrier frequency also allows to widen the communication channel. Miniaturization (higher frequencies = lower wavelengths = smaller antennas and systems)
