What is DAS?

DAS Stands for Distributed Antenna Systems. DAS is a network of spatially separated antennas that receive their waves from one central antenna, providing a wireless network within a geographic area or structure.

With a standard in-building DAS System, the cellular source is usually at a higher elevation, and it provides the wireless signal to the building.

Signals are transmitted into the building through head-end equipment which converts the Radio frequency signals to digital pulse signals.

Wireless distribution then disperses the digital signals throughout the building by way of fiber cabling, and are received by remote node locations that convert them back into Radio frequency signals and radiate them through multiple, strategically situated antennas for reliable in building wireless coverage.

For larger applications or for stadiums, cellular coverage is usually not an issue. The problem is when you have 80,000 fans at a football game the capacity of the macro environment cannot adequately service so many simultaneous connections.

DAS Systems for stadiums are fed through a carrier installed network of base stations.

This enables the integrator to sectorize the DAS Systems into many smaller areas, enabling many small cells which enhance the capacity and coverage.

A DAS system supports numerous wireless technologies, as well as public safety systems. It offers the capabilities for each industry’s unique specifications, be it healthcare, hospitality, enterprise, or alike, and allows access to radio communication for first responders in case of emergencies.

In-building cellular is now one of the leading verticals in the technology sector.

DAS and small-cell solutions are critical to the build out of wireless services, including wireless broadband. Today, consumers demand consistent wireless broadband coverage and capacity across every setting. To meet this demand, the cellular network is moving closer to the consumer, using a variety of licensed and unlicensed technologies working in tandem.

Today’s networks employ a variety of technologies from cellular towers, rooftop antennas, microcells, picocells, Wi-Fi and Distributed Antenna Systems. Together, these heterogeneous networks or (HetNet) technologies knit together the nation’s wireless networks.

Reliable wireless distribution is an integral part of business and pleasure, and it is only high quality wireless communication systems that can deliver an optimal wireless network system.  So it’s important to find a company that has the knowledge, expertise, and professionalism to handle your in building wireless installation.

    Thanks for the definition of DAS. I am in no way someone who knows much about computing or how things work, so the explanation of DAS and what it involves is highly appreciated! 🙂

    The definition and information regarding DAS is valued, as I have heard of the system before, but I had yet to find anywhere that actually explained it in a way that I could fully understand. I am more than interested in potentially having this installed into the office where I work, as we really do need an upgrade from our current low performance system…
