A distributed antenna system (DAS) is a network of antennas in a building or office park that helps to boost cellular signal capability or radio frequencies used by first responders. As you can see, a public safety DAS is critical for emergencies, but there are many facts that people don’t know about these sorts of networks. Here are three facts about distributed antenna systems you need to know.

It Works in Many Different Areas

As you know, public safety DAS helps first responders communicate during emergencies, making it an ideal system to install in a school, office, or government building. However, DAS also helps boost Wi-Fi and cellular signal capabilities, so it can benefit almost any location that receives plenty of foot traffic.

Some examples of places that could benefit from installing DAS are event spaces that hold large conferences or trade shows, airports, hospitals, concert venues, sporting arenas, hotels, and even subways and railroad stations. Whether for business or safety, DAS is a valuable technology to have near you.

DAS Can Be Passive or Active

There are two main types of DAS: passive and active. A passive system works by transmitting a signal through a network of antennas scattered throughout a property.

These antennas will rebroadcast a signal from a nearby cellular tower, which gives a strong connection to all the mobile devices within the vicinity. In addition, passive systems use less expensive equipment and less power than active DAS, so it’s a much more affordable solution for maintaining strong cellular connections in each area.

Active DAS is more suited to sites where cellular connectivity is highly demanded. An active DAS transmits signals throughout a wide area by broadcasting them from a central location. The equipment costs and electric needs of an active DAS are greater than those of a passive one, but the technology is also more effective and durable.

The Installation Costs for DAS Can Vary

When you want to install DAS in your area, you will most likely want to reach out to a consultant that can provide the best recommendation for the space. Generally, you can go with a passive DAS for places that are less than 100,000 square feet, but you’ll need an active system for areas that are 500,000 square feet or greater.

The cost of an active DAS is typically somewhere between $2 and $4 per square foot, while a passive system is usually $1 to 30 cents per square foot. When performing a cost analysis, keep in mind that the power requirements of an active DAS are far greater than those of a passive one.

Overall, DAS is a fascinating technology that can provide many benefits to almost any public space. After learning three must-know facts about distributed antenna systems, you should have a greater appreciation for how advanced our society has become.
