Spectrum is a range of electromagnetic radio frequencies used for transmission of voice, data and images . Mobile telecom operators send and receive frequencies to enable communication between two phones. The defence services and railways also use the spectrum .
Read moreWhich part of the spectrum is used for communication?
Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.

Read moreWhat is the difference between band and wavelength?
is that wavelength is the length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as , and corresponds to the velocity of the wave divided by its frequency while waveband is a range of radio wavelengths or frequencies; for …
Read moreWhat is meant by band in radio spectrum?
In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum , which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit.
Read moreWhat is spectrum and why is it auctioned?
A spectrum auction is a process whereby a government uses an auction system to sell the rights to transmit signals over specific bands of the electromagnetic spectrum and to assign scarce spectrum resources .
Read moreWhat is spectrum 2G 3G 4G?
The amount of spectrum used for the transmission of a radio signal. For example, a 2G (GSM) channel is 200 kHz wide , a 3G (WCDMA) channel is 5 MHz wide and a 4G (LTE) channel can be up to 20MHz wide.
