The Citizen Band Radio Service (CBRS) is a two-way, short distance, voice communications service that provides a cheap, reliable means of communication.
The service is for public access and available to everyone with no right of exclusivity to any one party and operates under a class licence.
Class licences do not need to be applied for nor is any fee due.
There are a total of 80 channels with a bandwidth spacing of 12.5 KHz. Previously the band had only 40 channels with a bandwidth of 25 KHz.
With the use of repeater stations, communications distances between CBRS increases.
Transmitter power is limited to 5 watts.
