What is a Public Safety signal booster?
A Public Safety signal booster, also called a Bi-Directional Amplifier (BDA), boosts the radiofrequency of the portable radios of first responders including police and fire to ensure reliable communication without any dead spots inside buildings. A BDA enhances all public safety frequencies including 700, 800 and 900 MHz to improve the quality of communications of first responders including portable radios and cell phone signals.
