What is a DAS System Used for?

Are you looking for a Public Safety DAS System for your facilities? Before buying or installing these systems in your building, you must know their work and uses. This blog will discuss a Distributed Antenna System and how it works. Let’s get started:

What is a Public Safety DAS System?

Public Safty Distributed Antenna Systems use BDA technology to provide improved two-way radio service through an antenna system. It ensures that first responders can maintain reliable and uninterrupted wireless communications within a building during natural disasters, medical emergencies, fires, and other life-threatening events. 

A BDA System is an in-building communication system that helps bring wireless signals into the structure from outside, amplifies those signals with a signal booster, and then distributes the amplified signals through a Public Safety DAS System.

How Does a DAS System Work?

A distributed antenna system improves cellular wireless signal with the installation of antennas and other components. A DAS is a network of antennas that sends and receives cellular signals on a carrier’s licensed frequencies, and after that, they improve voice and data connectivity for end-users. 

  • A Signal Source

A distributed antenna system distributes signals. However, it usually doesn’t produce the cellular signal itself. A DAS needs to be provided a signal from somewhere. 

  • Distribution System 

Once received, the cellular signals need to be distributed throughout the building. There are 4 types of distribution systems: active, passive, hybrid, and digital. 

Public Safety Distributed Antenna System

With the high demand for Public Safety DAS Systems, enterprises have started installing DAS Systems to extend coverage and increase capacity for mobile network connectivity for their staff and visitors who leverage the power of cellular wireless connectivity. DAS Systems are helpful for large buildings with high occupancy. The best thing about these systems is that they help with high-altitude buildings that struggle with atmospheric interference. 

For instance, hospitals could benefit from Public Safety DAS, which takes strong wireless signals and distributes them through difficult-to-cover areas and a high density of users. In addition to this, remote worksites and large campuses can use a DAS to connect outlying regions of their operations with public cellular services. 

Significance of Installing and Upgrading Public Safety DAS Systems

The State of Florida has released deadlines that mandate the compliance and testing of Public Safety Distributed Antenna Systems for owners of the building. It will ensure first responders can connect with each other when dealing with emergencies. Buildings requiring Public Safety DAS include:

  • Office buildings
  • Malls and retail centers
  • Parking areas 
  • High-rise buildings
  • Hotels and restaurants
  • College and school campuses
  • Arenas and stadiums

Building owners need to ensure their buildings have broad signal coverage. They must ensure to meet Public Safety DAS requirements. It is not enough to meet minimum compliance standards. It is the responsibility of building owners to safeguard each individual in and around their building. Building owners who get DAS systems installed in their buildings must comply with rules and regulations, help first responders during emergencies, and save lives with DAS systems. 

System Designing and Installing DAS Systems

DAS Systems providers offer different services, including site surveys, system designing, installation, and testing. 

  • Wireless communications service providers usually work with contractors or building owners to conduct a site survey, so that they can offer a DAS estimate. 
  • Once collecting all the requirements of a DAS System, they create a final design using iBwave software. 
  • After finalizing the system design, the DAS System installation will be done. 
  • After the installation of the system, it is the responsibility of technicians to test the system to check if it works properly. 
  • Once the building gets approval from the AHJ for the new system, it will receive its temporary certificate of occupancy. 
Benefits of Distributed Antenna Systems
  • Enhanced Network Coverage 

DAS identifies the problem of weak mobile network reception inside buildings. Distributing signal coverage throughout the building ensures that staff, clients, and visitors have consistent mobile service coverage. 

  • Improved Data Capacity

With the increased use of mobile data, DAS can enhance data capacity. It is crucial for businesses that rely on mobile data for operations, such as shopping centers, hotels, and office buildings, where several users may be accessing data services at the same time. 

  • Emergency Services

DAS Systems can support public safety communication systems, making sure that emergency responders can maintain communication in emergencies. These benefits make DAS an important consideration for businesses looking to enhance their in-building wireless communication capabilities. 


The blog covers detailed information regarding Distributed Antenna Systems to ensure first responders and emergency personnel have reliable and uninterrupted communication in emergencies. You can contact BDA Compliance to get the DAS System installation done at your premises.
