Public Safety: In Building Radio Coverage

What is a public safety signal booster or BDA?

A BDA, or public safety signal booster, transmits and receives critical communications during a crisis. 

It is a device that receives, amplifies, and retransmits signals from wireless stations, ensuring the firefighters and other public safety personnel can effectively communicate with their base stations on the outside.

In essence a BDA rebroadcasts a signal that may have otherwise been lost in one of your building’s dead zones.

Why do I need a public safety signal booster or BDA?

To ensure the safety of your employees and customers, new buildings are required to prove they provide adequate radio coverage on the Public Safety Radio System, which is the communication channel used by first responders.

Fire marshals have a mandate to enforce that your building meets standards of radio communication for emergency response.

If your building fails to meet emergency responder radio coverage standards during inspection, your building occupancy certificate may be denied, costing you time and money to rectify the problem.

MCA can guide you through the process of adhering to local code regulations in radio communication for your particular AHJ (authority having jurisdiction).

MCA Solutions for In-Building Communication for Public Safety


BDA Connectivity the need

The Need

Your new building requires a reliable radio signal to ensure that first responders can communicate inside your building.

BDA No Radio Signal the issue

The Problem

The materials used to build your building (cement, metal, and certain types of glass) prevent radio signals from penetrating all areas of your building.

BDA Save on costs

The Consequence

Local fire marshals will not provide a certificate of occupancy unless certain standards of radio communication are met, leading to costly delays.

What Codes and Standards Does My Building Need to Meet?

*Please note that codes vary by location, but the standards below offer general guidelines.

NFPA 72:

As outlined by the National Fire Protection Association (NFPA): “NFPA 72 provides the latest safety provisions to meet society’s changing fire detection, signaling, and emergency communication demands. In addition to the core focus on fire alarm systems, the Code includes requirements for mass notification systems used for weather emergencies; terrorist events, biological, chemical, and nuclear emergencies; along with other threats”

IFC 510.4.21:

This section of the International Fire Code states that “buildings and structures which cannot support the required level of radio coverage shall be equipped with a radiating cable system, a distributed antenna system with Federal Communications Commission (FCC)-certified signal boosters, or another systems approved by the fire code official in order to achieve the required adequate radio coverage.”
