What is a BDA System?
The Bi-Directional Amplifier (BDA) System is a signal-boosting solution designed to enhance in-building radio frequency signal coverage for public safety radios. These two-way radio signal boosters are used to bring facilities into compliance with both local code and Emergency Responder Radio Coverage (ERRC) code. These systems are often referred to as ERCES or Emergency Responders Communication Enhancement Systems. Ensuring that radio signals can effectively permeate all areas of your facility increases the safety of everyone inside.
Code Compliance
The National Fire Protection Association (NFPA) is the foremost authority on fire, Electrical, and related hazards. NFPA 1225 addresses in-building communication for first responders. Many municipalities and other Authorities Having Jurisdiction (AHJ) have adopted NFPA 1221 and more recently 1225 in their building codes and thus require in-building communication for first responders. Codes vary by local, but these codes often apply to new building permits and sometimes require the retrofitting of existing public buildings.
What can a BDA System do for my Facility?
Public safety personnel responding to incidents depend on constant radio communication with dispatch and each other. Weak radio signals inside a building can delay or impede the ability of first responders to provide adequate help. Countless after-action reviews cite that poor communication reduced the effectiveness of an emergency response. By investing in one of these systems, you’re increasing the safety of employees, visitors, and anyone else inside your facility, as well as protecting those who rush onto the scene to help in emergencies.
How does it work?
A Distributed Antenna System, or DAS, refers to the collection of parts used to amplify and distribute a radio signal throughout a building or other desired area. The system will pull the desired signal from the external macro radio system and then amplify it with a repeater or bi-directional amplifier (BDA). Transmission lines run through the building carry the signal to antennas which are strategically placed throughout the building
Improving in-building coverage is more than pumping in higher signals. Too much signal can cause interference and degrade communication in other areas. Successful DAS solutions use the best-fit components for the building and are optimized to deliver just the right amount of signal in each area without interfering with adjacent areas or the external macro radio system.
State-of-the-art Signal Mapping Technology
At Tele-Rad, we can provide you with a detailed signal mapping that can detect where the signal is weakest in your facility. After assessing what is needed within the building, bi-directional amplifiers can be used to improve radio communications in buildings where signals are degraded due to obstacles that obscure the signal.

Who needs a BDA System?
Many facilities now require BDA installation with new or building renovation permits and certifications. Any building where first responders, maintenance, and security personnel need to maintain constant two-way communications.
- Governmental Buildings
- Hospitals
- Hotels
- Manufacturing Plants
- Schools and Campuses
- Stadiums and Arenas
Tele-Rad proudly partners with Motorola Solutions as well as other top-tier vendors who assist with engineering and design for these solutions, as well as providing durable components. If you’re interested in learning more about this process, don’t hesitate to contact us! If you already have a BDA system installed, we would also be happy to work with you to put together a system support agreement, ensuring that it is regularly tested and optimized for many years to come.
