Basic exchange telecommunications radio service
Encyclopedia
In telecommunication
, a basic exchange telecommunications radio service (BETRS) is a commercial service that can extend telephone
service to rural areas by replacing the local loop with radio
communications
. In the BETRS, non-government ultra high frequency
(UHF) and very high frequency
(VHF) common carrier
and the private radio service frequencies are shared.
Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
