What’s really the difference? BDA vs. DAS

Industrial BDA/DAS

What's the difference? BDA vs. DAS

What even are they? Both BDA (bi-directional amplifier) and DAS (distributed antenna systems) can be categorized as Emergency response solutions in terms of enhancing communication and reception. When the ability to communicate is critical, much like in an emergency, both BDA and DAS solutions offer the reliable communication you need to interact safely and keep up operations. Both solutions have the same goal of amplifying connection, but one amplifies it from the outside of the building in (BDA) and one from the inside of the building out (DAS).

Are they just for emergencies? Short answer….NO! There are undoubtedly adverse effects on your radio signals if you have a concrete or metal framing structure. Oftentimes, these structures interfere with the flow of connectivity and impact your signal. A perfect example is loss of signal while in a stairwell or parking garage. These types of environments aren’t suited to solely support connectivity. While they’re imperative for communications in an emergency like a fire or a bad storm, today, businesses across the country are seeking stronger and more consistent connectivity for their employee’s day-to-day work environment. To summarize, while these systems can be a life-saving measure in a pinch, they can also be the solution to maintain your organization’s infrastructure as your business ebbs and flows throughout its operations.

What’s the difference between BDA & DAS? While they are different, it’s easier to remember the similarities than the differences between BDA & DAS. DAS is a system of antennas that distribute a connection throughout large areas or buildings. BDA is a more extensive antenna system that incorporates both system’s functionalities. Different industries and markets call for different approaches depending on the size, area and use cases, but essentially both systems maximize communication in interchangeable ways. 

Do you need one? If you’re not sure where to start, there are site surveys that test your building’s radio frequency as the first step before amplifying your coverage. Did you know most states are required to follow federal registration guidelines before implementing one of these solutions and require a minimum amount of coverages? To check your state’s regulations, visit the FCC’s website today. Don’t hesitate! Repair your building’s in house cellular reception today, with STARCOMM’s BDA & DAS solutions.
