Why choose a license-free radio over a licensed radio?
License-free radios operating under FCC spread spectrum ISM band regulations tolerate interference from neighboring radios and interference from sources other than radios, making them less prone to signal loss. Here’s why: The radio spectrum is divided into frequency bands, with each band divided into frequency channels. The bands and channels are regulated around the world as licensed or license-free. The term ‘licensed radio’ refers to a radio that is licensed by a government agency to operate on one channel in one geographic area at one time. The intent is to protect the licensed radios from other radio interference by limiting the radios on a channel. Unfortunately, while government agencies can control radio users, they cannot control interference that is generated on licensed frequencies by non-radio emission sources such as motors, drives, arc welders, power lines, etc. The term ‘license-free radio’ refers to a radio operating with government permission on a specified frequency
