eXtreme Radio Service

eXtreme Radio Service (eXRS) is a proprietary personal communication technology marketed by TriSquare in the United States. The radios, which are similar to other walkie-talkies, use the Part 15 low power communication 915 MHz band, and employ frequency-hopping spread spectrum FM technology to attempt to address some of the perceived shortcomings of FRS radios. Since the frequency in use is rapidly changed in a pattern defined by the channel number, transmissions cannot be monitored by commercially available radio scanners.
