What is a distributed antenna system used for?

 

What is DAS, in short

A distributed antenna system (DAS) is a radio frequency (RF) network that distributes cellular signals through large indoor environments. The spaces can vary from convention centers, stadiums, and airports where there’s high demand for cellular service due to many people using their phones and other devices at once.

A cellular DAS consists of all the components necessary to receive and send radiofrequency signals, including antennas, cabling, amplifiers, and other electronics housed in a single room or small area.  

So, what is DAS?

 

What makes up a DAS System

A distributed antenna system (DAS) is a network of antennas, amplifiers, and several other components. These allow wireless service providers to deliver cellular data within buildings without extensive infrastructure.

DAS architecture consists of multiple antennas, typically mounted on the ceiling or walls in locations where coverage and capacity are needed. Fiber optic cables and electronics are also called upon to distribute the signal throughout the facility where required; these form an integral part of active and passive DAS systems.

These components include an antenna tower located on the rooftop or nearby areas outside the building. This tower transmits signals from cellular towers through fiber optic cables to an indoor unit (IDU), which receives and distributes radio frequency (RF) signals throughout the building.

A typical DAS network has several benefits over traditional wireless systems, such as improved coverage, higher capacity, and lower cost per bit delivered and provides an equal signal strength distribution across a given space.

 

How is a DAS System used

DAS is ideal for significant, crowded indoor events and venues where there may be many different wireless carriers with users all trying to connect at once. This can result in bad phone reception, a congested network or slow data speeds that make it difficult for people trying to communicate via their phones or tablets during an event.

Cellular DAS systems and other types of DAS are used to distribute radio-frequency signals from a central point to multiple locations. These systems also enable public safety agencies to access critical communication in the field.

Public safety agencies always look for ways to improve communication, particularly in rural areas where infrastructure can be subject to underdevelopment or increased risks of failing.

 

The main takeaways 

A DAS solution is a cost-effective and efficient way to provide wireless coverage in large, crowded areas. A DAS is easy to install and requires less power than traditional cell towers or repeater systems. 

Access to the internet at all times is essential for consumers as much as it is for public safety agencies and businesses. Therefore, it’s important that they have access everywhere they go so that they can always communicate with others quickly and effectively!
