Bi-Directional Amplifier (BDA)

BDA SYSTEMS
BDA systems, also known as an Emergency Responder Communication Enhancement Systems (ERCES) or Bi-Directional Amplifier, is a signal-boosting solution designed to enhance in-building radio frequency (RF) signal coverage for public safety radios. Depending on the type of commercial or industrial facility you manage, you might find it difficult to communicate with every part of your building. This can be especially problematic for Emergency Responders who use their handheld radios when they need to make important or time-sensitive communications to other emergency responders. Building code requires that you correct this with a BDA system.

Buildings requiring a BDA system include:

Hotels
Factories
Industrial
Storage Facilities
Schools and Universities
Apartment Communities

Are BDA System May Be Required By Law? An in-building DAS system increases the safety of building occupants. In cases of emergency, a public safety DAS system or ?I-BAND? network facilitates indoor 911 calls and is better equipped to handle the multitude of simultaneous calls that would otherwise overwhelm the available wireless coverage. It also provides first responders with improved communication. Public safety personnel such as firefighters and policemen require a reliable wireless network to communicate ? whether by voice or by data content. This is especially true in critical areas such as stairwells, where unaided radio frequency signals are weakest. For these reasons, in-building amplification systems are already being required in certain municipalities.

As you can see in the illustration, using the BDA system the responders are able to communicate with ground command without any issue.
