What are Cellular DAS / BDA systems and who needs them?

Boost cellular coverage across your building, even in areas that were previously lacking signal, like stairwells or underground tunnels. A Distributed Antenna System (DAS) is a network of antennas designed to boost and sustain wireless signals throughout a facility where there may otherwise be little or no coverage. A Bi-Directional Amplifier (BDA), also known as an in-building amplifier, is a device that amplifies in-building and external cellular signals .

A well-designed in-building amplifier system can bring in cellular signals from outside your building and distribute wireless coverage across that structure. Consistent coverage in your facility is crucial to maintaining operational efficiency and keeping people safe in emergencies. Both staff and visitors benefit when there is a reliable cell signal across the entire building.

Why choose Air Comm to install your DAS/BDA system?

Air Comm has been designing communication systems since 1973. Our team of signal experts can perform grid testing to verify existing cell signal conditions. Based on those results, we can design and install a cellular DAS/BDA system that provides the most reliable and efficient wireless coverage possible. Our engineers work with industry-standard software to design systems that will perform in any situation.

A poorly designed cellular DAS is a common problem in this industry. We've seen systems that interfere with nearby Public Safety radio sites. Another common problem is inexperienced installers not coodinating with cell carriers, often resulting in poor system performance.

Air Comm knows this technology better than anyone, and we'll use that knowledge to make sure that your project is successful.
