How Do Distributed Antenna Systems Work?

Distributed antenna systems, also called DAS, are used in large or complex venues and buildings to improve cellular coverage. When optimized and installed correctly, they can connect someone at the top of a skyscraper to security guards in the basement. DAS essentially gets the most out of your current wireless signal. It will amplify your signal where it’s needed most. In this article, we’re going to take a closer look at exactly how distributed antenna systems work and why you might consider one for your building or venue. 

How does DAS Work? 

You already know that a distributed antenna system essentially amplifies and optimizes your current wireless signal. The system gets the signal from your service carrier and can even be used with multiple carriers by using multiple antennas in the areas that need extra attention. A DAS solution is designed for each unique property. Your installation partner takes into account every aspect of your structure, including materials, type of ceiling, and the size of rooms. They test and document the weakest areas throughout your property to inform the overall design. 

How Do DAS Installers Configure the System? 

Because no two buildings are the same, there is no standard set-up for a distributed antenna system. Even buildings with the same architecture and square footage will have unique surroundings and limitations to consider. Your DAS installer will take into account your feedback and site surveys to determine where to best position the equipment. The DAS installer will optimize each location for signal quality and data rates. 

How Does the DAS Signal Spread? 

DAS do not create a signal; they amplify the existing one. DAS can use fiber optics, digital, or passive mechanisms to deliver the amplified signal throughout the building. Your installation partner may suggest an off-air signal if you have a strong donor signal and local tower. With this system, you can use an antenna on the roof to carry signals from a cell carrier. 

Who Can Benefit from a Distributed Antenna System? 

Typically DAS is installed when an area is too large to handle the data demands of the people using a property. Bandwidth can quickly get maxed out when thousands of people are all using their electronic devices at the same time. Sports arenas are a classic example. Buildings that have tenants with complex network demands are also good candidates. DAS is also a solution when physical barriers are present. Hospitals with fortified construction and high altitude skyscrapers benefit from DAS. Even energy-efficient glass can block a signal, making DAS the only solution. 

Choosing the DAS Partner 

Distributed antenna systems provide you with the capacity that users need to enjoy devices no matter where they are on your property. Most importantly, it keeps tenants and guests connected during an emergency.
