BDA – What is it?

BDA is a system that helps to enhance in-building radio frequency signal coverage for public use. 

Do I need it?

All facilities now require wireless signal testing with the possibility of an installation of a BDA System if the signal doesn’t meet the safety requrements.


Reliable radio coverage is essential for first responders during emergencies.


All existing commercial buildings in Florida need to comply with required minimum radio strength for the fire department communications and two way radio system enhancement communications as required by the Florida Fire Prevention Code by January 1, 2022.


If your building has inadequate coverage, in the event of a public emergency such as a fire, the First Responders will not be able to communicate effectively to all team members at all times.  This could potentially lead to enhanced risk of injury, death, and loss of property. 

What is a BDA System?

A Bi-Directional Amplifier System (BDA) is a “reliable in-building public safety radio coverage infrastructure system used to safeguard emergency communications”.

Primary use of a BDA System?

A BDA System is primarily used to address the performance of emergency responders’ portable radios and maintain wireless communications with the first responders inside buildings and emergency personnel outside the building during medical emergencies, fires, etc.  

Building construction, size, and construction features (such as Low-E windows) can absorb or block radio communications.  With adequate levels of signal strength, efficient communications can save the lives of first responders and building occupants alike. 

How could a BDA System save lives?

First Responders heavily rely on radio communication and reliable radio coverage during emergencies is essential.

A notable time when a system failed was during the 9/11 attacks.  Clear warnings from emergency command centers were received by first responders around the buildings instructing crews to pull fire fighters out due to obvious structural damage.  These warnings were sent 21 minutes before the second tower fell.  Even though the ground crews communicated that information through the radio system, the lack of signal strength inside the buildings contributed to hundreds of lives being lost that day.

Is my facility required to be tested for a BDA System?

All facilities now require BDA testing and installation with new or building renovation permits and certifications.  Any building that is identified and inspected under local ordinances and/or is requiring public safety permits should be tested. 

What types of facilities are required to be tested for a BDA System?

Examples of facilities that should schedule a BDA test are…

  • Airport Terminals
  • Apartment Buildings
  • Assisted Living Facilities
  • Commercial Buildings
  • Convention Centers
  • Government Guildings
  • Hospitals
  • Hotels
  • Manufacturing Plants
  • Parking Garages
  • Retail Shopping Malls
  • Schools and Campuses
  • Stadiums and Arenas
  • Storage Facilities
  • AND MORE!!!
Why are BDA Systems required?

Within the last two years, 56% of fire departments have experienced communication failures during an emergency incident.  If a building has areas where emergency signals are not sufficient for reliable communications, a distributed antenna system (DAS) will amplify and distribute the signals to the needed areas. 

What is a DAS?

A Distributed Antenna System (DAS) has the ability to amplify and distribute signals to needed areas.  They are used when a system is installed but coverage isn’t equal.  The installation of a DAS would help distribute the RF signal throughout a building, stadium, hospital, or other defined ares.
