Why BDAs Are Required

Radio signals are weakend by concrete, below-ground structures, RF interference, distance from public safety radio repeater, and more, all of which may severely harm radio communication. This creates a very real hazard to both building occupants and emergency responders themselves.

To solve this problem, both International Building Code and International Fire Code require the installation of bi-directional amplifiers to upgrade the in-building radio signal and provide reliable communications for fire, police, EMS and other public safety personnel.
