Public Safety DAS & BDA Requirements

As a result of the crucial element when it comes to public safety, building and property owners are faced with numerous challenges before the construction project can be approved. Public safety is one of the main considerations in public buildings. That is why it is important that you look for experience and reliability when searching for distributed antenna system companies.

Both the International Fire Code (IFC) and the National Fire Protection Association (NFPA) have imposed some requirements on those buildings that have been recently constructed. A newly constructed building with a minimum area of below 50,000 square feet must have a minimum signal strength of 95 dBm. The certificate of occupancy will only be rewarded once all the safety standards are met.

Booster systems, Bi-directional amplifier systems, advanced public safety in-building wireless, and DAS all help in complying with these safety requirements. The cost of installing such equipment can become expensive once a building is completed compared to when it is still under construction.

Deployment Process

There are a couple of factors to consider when installing DAS and BDA in terms of public safety. That is why a construction manager should consult with a wireless provider for assistance as the deployment is technical in nature and requires experienced personnel.

A DAS installation will usually require two antennas: The directional antenna which is aimed towards the donor, while the other antenna is meant to distribute signals throughout the entire building. The best way of ensuring maximum signal strength for safety requirements is by putting the donor antenna in the line of sight of the source. The distribution antenna needs to be as close to the service area as possible because of emergency and safety purposes.

Compliance Requirements

In order to meet safety requirements, the DAS needs to provide adequate communication for first responders during an emergency situation. The majority of municipal and state laws are governed by the codes that impact the DAS and BDA installations. For instance, you might find that a state requires exceptionally high-levels of in-building signals which should pass yearly fire inspections.

There are a couple of safety codes that are in existence that govern the installation of DAS and BDA systems. These codes are usually enforced by the local authority in a municipality or a state. There are three primary organizations that are in charge of enforcing and regulating public safety, regardless of the jurisdiction.

DAS can be divided into two: Class A and Class B. The type of Class that is appropriate for you will depend on the unique circumstances. Class A boosters have the ability to filter out undesirable channels and maintain stable output levels. DAS boosters are usually categorized under class A because they meet these requirements. Class B boosters have challenges when it comes to coverage. This is because they can undergo fairly major fluctuations in power output. This impact to coverage and communication can sometimes drastically affect the radio communication channels used in emergency instances. 

After deciding the booster that fit your needs, it is important to make sure it conforms to the local state safety guidelines. For more information, you can check out
