Quick Guide to Bi-Directional Amplifiers and Distributed Antenna Systems for Public Safety Communications

Commercial and residential buildings present unique communication challenges for emergency responders and poor radio communication can have tragic consequences in an emergency situation. Many first responders rely on radios to communicate in buildings, but these radios often don’t work well in larger scale residential or commercial buildings. This can lead to dangerous situations when first responders can’t communicate with each other.

Modern construction and materials have made it difficult for police and fire emergency responders to reach dispatch or incident managers. Responses can be delayed due to poor radio coverage, which could lead up to having severe consequences if not addressed immediately.

The need for in-building coverage is increasing as more people live and work inside larger buildings. The problem becomes especially critical when these areas are densely populated, making it difficult to communicate with those inside and outside the facility during emergencies such as fires or natural disasters.

For public safety, legal statutes may require strict in-building two-way radio coverage. Let Diversified help you by describing an effective communications strategy so that all of your questions and concerns will be answered before making any decisions.

Bi-Directional Amplifiers (BDA) and Distributed Antenna Systems (DAS)

First responders need a way to communicate instantly because situational awareness could mean the difference between life or death. All large residential and commercial buildings should provide wireless coverage for public safety and emergency responders with bi-directional amplifiers (BDA) and distributed antenna systems (DAS) installed throughout large residential structures and office buildings.

The benefits of a BDA & DAS system are immense. Not only will first responders be able to communicate more effectively, but they’ll also have access the latest information about an emergency situation so that dangers resulting from poor communication can quickly be mitigated or eliminated.

A strong signal improves radio communications in-buildings which saves time. Whether that be for firefighters fighting fires or police officers responding to a call. Emergency responders being informed by their dispatchers can save time, and lives.

Most recently, many municipalities have building code requirements addressing the requirement of BDA and DAS installations. These are necessary for ensuring that your business or residential building can operate in compliance with local regulations while also protecting against potential dangers.

The National Fire Protection Association (NFPA) code 72 chapter 24 states that 90% of in-building coverage is obligatory. However, the requisite jumps to 99% for more dangerous areas such as elevator lobbies, exit stairs and passageways, and fire pump rooms. Moreover, the International Fire Code (IFC-510) code necessitates 95% in-building wireless signal coverage with a minimum signal strength of -95 dB. All public safety communication BDA/DAS systems also need to function under high heat and humidity, while being able to run on battery power for 24 hours.
