Public Safety Two-Way Radio ERRC Signal Booster BDAs and DAS

A two-way radio signal booster is not necessarily needed. The only way to know the answer is to have your building tested. Codes merely require adequate two-way radio clarity and coverage. If your building has sufficient clarity and coverage to meet your local code, you do not need a system.

Unfortunately, no. Cellular boosters are only FCC approved to rebroadcast the cellular carriers’ frequencies. Two-way radio or FirstNet are not supported. However, depending on your local codes, you may be able to add two-way or FirstNet coverage to your existing cable and antenna infrastructure.

The number of devices that can make use of the better cell signal provided by our public safety cell phone signal boosters depends on the power of the booster. As a general rule, if you buy a commercial system, you should not have to worry much about capacity.

A major cause of poor signal is building material. We strongly recommend a system design before making any major equipment purchases, as our expert team of designers are well-versed in signal loss from internal obstructions.

Each Authority Having Jurisdiction (AHJ) has their own codes and requirements. Each city does have requirements for in-building emergency radio coverage. In fact, most cities and counties have codes regarding expected coverage indoors for first responder two-way radios.

No. There are strict requirements for the training and expertise necessary to correctly install ERRC (Emergency Responder Radio Coverage) systems. This project is best left to the experts.

That is not entirely correct, there are exceptions. Most codes require testing and coverage if your building has one (or more) of these three characteristics:

• Is more than 3 stories
• Has any subterranean space
• Has an aggregate of 50,000 sqft or more

We offer 2-3 year warranties on all our systems, a year on all labor, and lifetime technical support. Should your system require maintenance, we also are able to come back to your site and make any necessary adjustments or changes to make sure it’s working as optimally as possible.

Signal Boosters also guarantees the professionalism of our employees and will schedule their visits based on what works for you. The installation of your radio signal booster will be conducted in such a manner as not to inconvenience your normal operation.

BDA systems work by capturing weak radio signals from a donor antenna placed outside the building, amplifying these signals using bi-directional amplifiers, and then redistributing the boosted signals throughout the facility using a network of antennas connected to the Distributed Antenna System (DAS) or BDA/DAS setup. This process is also reversed for outgoing signals, ensuring seamless two-way communication.

These enhancement systems, like the Cel-Fi by Nextivity GO RED FirstNet and other cell boosters, are specifically designed to maintain strong signal strength and reliable connections, even in challenging environments such as large buildings or areas with poor signal coverage. To comply with local regulations and codes require, BDA systems must be FCC certified and meet specific criteria set by the Fire Protection Association (NFPA) to ensure public safety and effective communication for emergency responders.

While BDA and DAS cell phone boosters share similarities, they are not the same. A Bi-Directional Amplifier (BDA) is a specific component within a Distributed Antenna System (DAS) that helps amplify and improve signal strength for radio communication. A DAS, on the other hand, is a complete network of antennas, including BDAs, that work together to distribute and ensure reliable signal coverage throughout a building or facility — similar to the Uniden Hero First Net and other cell phone signal boosters.

A Distributed Antenna System (DAS) is a network of strategically placed antennas connected to a central source that works together to enhance radio frequency (RF) signal coverage within buildings or large facilities. DAS systems are designed to improve signal strength, ensure seamless communication for emergency responders, and meet code compliance requirements set by authorities like the National Fire Protection Association (NFPA). DAS systems often include Bi-Directional Amplifiers (BDA), like the Comba CriticalPoint Public Safety 700/800 MHz and other cell boosters, to improve signal strength and maintain a reliable connection.

The primary difference between a DAS and a BDA system lies in their function and composition. A Distributed Antenna System (DAS) is a comprehensive network of antennas and components designed to distribute and enhance radio frequency (RF) signals within a building or facility, much like the Westell Public Safety 700 MHz Digital Repeater and similar cell phone boosters. In contrast, a Bi-Directional Amplifier (BDA) is a specific component within a DAS that focuses on amplifying and improving signal strength for two-way radio communication. While both systems contribute to ensuring reliable connectivity and meeting code compliance requirements, BDAs are a part of the larger DAS network.
