Bi-Directional Amplifier System (BDA):


Bi-Directional Amplifier Systems is a technology that facilitates two-way radio communications across multiple sections of a facility, such as stairwells, parking garages, underground tunnels, and other areas notorious for dead zones or poor coverage. Examples of facilities that rely on a BDA include hotels, hospitals, and manufacturing plants.


We offer BDA systems installation and maintenance for your existing or newly constructed building. Our skilled team of technicians handle everything from mapping out placement and deployment to ensuring all compliance requirements are met. Our state-of-the-art equipment ensures teams can stay connected and communicate in emergency situations.


By boosting and repeating signals across a multitude of frequencies. BDAs comprise a vital part of a Distributed Amplifier System (DAS), the network consisting of a series of amplifier nodes connected to a common transport medium. The collective term for a BDA/DAS system is what’s typically referred to as wireless In-Building Solutions. These two-way radio signal boosters are designed to assist facilities with maintaining Emergency Responder Radio Coverage (ERRC) code compliance.


When a BDA is operational, it will seek out and capture the wireless signal that is being used in the facility, which usually comes from a rooftop amplifier. Once the signal is captured, the BDA will amplify it. Think of it as a concert in a large venue. The microphone captures and “amplifies” the performer’s voice or instrument so that everyone can hear them clearly regardless of where the audience member is seated.


A BDA not only provides essential communication, but it also ensures that first responders are able to communicate, it can boost business productivity, and it is able to address virtually all major cellular carriers within a single structure.
