Why Do I need a BDA?Why Do I need a BDA?

When cell phone and two-way radio coverage is impaired inside structures, tunnels and other obstructed areas.

Safety reasons, it is important to have radio, paging or cellular coverage inside a building that has spotty or no coverage.

Allow cell phone and two-way radio users to operate handsets within a building or weak coverage area while maintaining clarity and quality

What does a BDA What does a BDA system consist of?system consist of?

One or more Amplifiers located inside the building

An internal and external antenna network.

How does it work?How does it work?

The external antenna, usually located on the roof of the building needing coverage, receives the signal coming from the radio site, and brings it into the amplifier. This antenna also radiates a signal back to the radio site thus the term, bi-directional. The internal antenna network, radiates a signal into the building in all needed locations, and receives the signal from the radio being used in the building, back to the amplifier.
