Consider the amount of time that is spent in buildings on our phones. Because our devices need to be constantly connected to a network, we need technology that is capable of handling a massive amount of mobile connectivity. Distributed Antenna Systems (DAS) are constructed in almost every type of indoor and outdoor space to increase mobile connectivity in these spaces. Since the need for mobile connectivity is at such a premium these days, any space without a mobile connection will get left behind. DAS systems are the solution to connectivity problems. In this blog, we will go into detail about how a distributed antenna system works and why you should consider it for any of your infrastructure projects.

WHAT IS A DISTRIBUTED ANTENNA SYSTEM?

A DAS is a network of antennas that sends and receives signals on a carrier’s licensed frequencies, which will then improve voice and data connection for users. During installation, the system is connected to the building through a series of fiber optic cables. Indoors, remote units are deployed throughout the building to boost indoor systems and push the signal towards the antennas.

HOW DAS WORKS

To simplify things, the antennas themselves have two basic components: a signal source and a distribution system. A signal source feeds the signal into a DAS system. The signal usually comes from different types of signal sources: off-air (through an antenna on the roof), an on-site Base Transceiver Station and small cells. A distribution system distributes the cellular signal throughout the building. Four different types of systems can be used, like active, passive, hybrid and digital.

WHY YOU NEED A DISTRIBUTED ANTENNA SYSTEM

There can be a variety of reasons for why you need to deploy a DAS system, but it generally comes down to whether the occupants of your building are connected or not. Without a DAS system, cellular signals are sent from a Verizon or AT&T tower (or whoever the carrier is) that must then permeate the building and be shared by everyone using the signals from that same tower. Signal degradation is highly likely in this case, which leads to dropped calls and poor cellular coverage.

But in a lot of cases, the signal will never even reach the inside. Most buildings are constructed with concrete, steel, and reflective glass, all of which blocks the cellular signals. So even if the carrier towers are connecting phones outside of the building, the signal can be lost once the user goes through those doors.
