What is LFR ?
License-Free Radios (LFR) are radio devices that operate on specific frequencies without the need for a license from the Department of Telecommunications (DoT). These radios are designed to be used for short-range communication, making them ideal for use in small businesses, factories, and other similar settings.
The DoT has designated specific frequency bands for LFRs to operate on, including the 136-174 MHz VHF band and the 403-470 MHz UHF band. These frequency bands are well-suited for short-range communication, with a range of up to 3-5 kilometers depending on the terrain and obstacles in the area.
