A Bi-Directional Amplifier (BDA) is an amplifier which amplifies radio frequency (RF) signals in two directions simultaneously, both from a subscriber up to the radio repeater system and back down. BDAs improve indoor coverage for radio communications, cellular signals, and are occasionally used for improvements in outdoor coverage.
A BDA is a signal amplifier device that sustains two-way communications and amplifies the signal. BDAs work in both transmitter and receiver mode throughout a facility–including it’s stairwells, underground tunnels, parking garages, and other challenging areas. In short, it is a signal boosting solution designed to enhance indoor signals coverage for public safety radios.
These systems are frequency band specific in that they are built to amplify one or more frequencies / channels within a specific frequency band.
