WHAT IS A LICENSE RADIO?

Before delving into the details of "Licence Radio," it's crucial to grasp the concept of a license and why it is imperative to obtain one. Our discussion primarily centers around radio communication or wireless communication. For the transmission of signals or information, be it voice or data, from one location to another, we require a carrier, much like an aircraft that serves as a means of transporting people or goods. In the world of radio communication, this carrier takes the form of a specific radio frequency spot. This spot frequency serves as a line for communication between individuals or entities in separate locations.

Given that numerous individuals and organizations within a country need to utilize such wireless pathways concurrently and in significant quantities, a multitude of frequency allocations are necessary. The aggregation of all these frequency allocations is called "Frequency Spectrum." Depending on the diverse range of wireless devices in use, this entire spectrum is subdivided into distinct groups known as "Frequency Bands." Such frequency bands are:

a) VHF Low Band (66-88MHz);
b) VHF High Band (136-174MHz);
c) UHF Band (380-512MHz);
d) License-free Band (446-446.2 MHz).

To put it precisely, a "license" in this context serves as official permission or authorization granted by a regulatory body, such as the DOT in India, to utilize specific radio frequencies for wireless communication purposes. This license is a legal requirement to ensure orderly and interference-free communication in an environment where multiple users are vying for access to the limited radio spectrum resources.
