BDA – What is it?

First responders rely on two-way radio communication to keep people and property safe.  Often they face a dangerous loss of communication that presents a clear and present hazard.   Factors that can lead to a loss of signal include the location of and proximity to the nearest public safety antenna, various obstructions, the building materials used, low e-glass, underground locations, RF or radio frequency interference – just to name a few.


Over 98.5% of first responders report dead spots in buildings. In the last 2 years alone, over 56% of responders reported a loss of communications. The problem is real – Our Emergency Responder Radio Communication Enhancement Solution (ERRCES) can provide 100% coverage insuring the best possible outcomes for everyone.

Our solution is currently the only UL 2524 listed bi-directional amplifier. The BDA boosts the signal from the public safety antenna and distributes it where needed through a Distributed Antenna System or (DAS). This amplification boosts signals in both directions making sure no communication is lost.


BDA – Why is this system important to you?

Current codes requirements call for a minimum of 95% coverage throughout all new buildings. The National Fire and Protection Association or NFPA requires 99% building coverage of all “critical areas” in a building.
By 2022, all buildings will be required to meet the standards as laid out by the governing authorities.
