BDA Systems

The Challenge

There are reportedly over 6 million commercial buildings in the United States. Occupants need to be able to call 911 from inside those buildings, and first responders need to be able to communicate when inside those buildings.

To overcome this challenge we use bi-directional amplifier (BDA) systems. A BDA system is a signal-boosting solution to enhance in-building radio frequency signal coverage for public safety radios and cellular devices.

Who needs a BDA system?

Any building with poor radio coverage for emergency responders must have a BDA system, as per IFC Section 510-2017 and NFPA-72.

In an emergency, it is vital that all buildings support wireless communications for first responders. Compliance is essential to ensure a high level of life-safety protection for both the people inside the building and the first responders.

Compliance deadlines vary, but many jurisdictions already require coverage testing and BDA systems to fix poor coverage and make a building code compliant.

In-building radio requirements

IFC Section 510-2017 – All buildings must have approved radio coverage for emergency responders within the building based upon local AHJ public safety communications requirements.

NFPA-72 – Chapter 24 of NFPA-72, Emergency Communications Systems states that radio coverage shall be provided at 99% throughout areas deemed critical and 90% in general.
