Indoor Public Safety DAS: Everything You Need To Know

Technology Blog

A commercial building's good network and communication coverage are key to ensuring tenants run their operations smoothly. Besides comfort, it enhances safety in emergencies like a fire outbreak by enabling efficient communication and coordination between paramedics, law enforcement, and firefighters. However, achieving good network coverage can be challenging, especially if your building is big with many rooms and floors or it's situated in a place with network barriers. Installing an indoor public safety distributed antenna system (DAS) helps deal with network barriers and maintain effective communication. Below is a guide to understanding how in-building public safety DAS works.

What's an Indoor Public Safety DAS? 

Indoor public safety DAS are connectivity systems that ensure wireless communication and reception in the interior of large or complex building structures by transmitting cellular signals between multiple discrete antennas or nodes. The multiple antennas help eliminate gaps in coverage as there are more propagation channels in operation. The system uses both passive and Active DAS configurations. A passive DAS uses amplifiers and splitters to capture outside cellular signals and distribute them into the building. On the other hand, an active DAS configuration creates signals using ethernet and fiber-optic cables installed in a building.

How's Indoor Public Safety DAS Installed? 

Like any other building project, installing an indoor public safety DAS starts with an in-depth survey of the building. That includes checking logistical issues such as the complexity of the structure and materials used for your building, dead zones, carrier strength, and aesthetic requirements of the building and surrounding area. The installation company then creates an installation plan based on the information gathered and starts the installation process. They also have to adhere to regulatory requirements to ensure the type of DAS systems installed suits the building. Examples of such requirements are fire and water-proof tools, the ability to support frequency update requirements, battery backup and 24-hour performance, and the availability of system monitoring fire alarms. 

Is Indoor Public Safety DAS Coverage Mandatory for All Buildings?

In-building public safety DAS coverage is not mandatory for all buildings. However, many local states are increasingly changing building codes to make buildings with high safety requirements mandatory. Examples of such buildings include office buildings, schools, storage unit facilities, large parking structures, malls, high-rises, hotels, hospitals, stadiums, and transit centers like airports and train stations. It is therefore important to install a DAS system to ensure adherence to regulations and avoid future issues with law enforcement. 


In-building public safety DAS installation is important in enhancing the safety of the occupants of your building during emergencies. Moreover, it's a great investment that ensures you move with modern demands of connectivity and compliance with regulations.

Understanding Technology Every Day

After I started having problems following other technologies, I realized that I needed to work harder to stay on top of new information. I began focusing more seriously on reading different literature about technology, and it was really cool to see just how much different companies could help. We updated our software programming and installed some new equipment, and it was nice to see how much of an improvement things made. I wanted to start this website to help other people to understand and apply new technology each and every single day. Read more on this blog to find out what you might have missed along the way.
