Distributed Antenna Systems (DAS)

In today's rapidly developing digital world, widespread wireless coverage is becoming less of a convenience and more of a necessity. This trend spans across organizations in a variety of sectors, including educational institutions, medical facilities, corporate offices, lodging facilities, and sports stadiums, just to name a few. Despite advancements in technology, single network antennae are often unable to project the signal to all areas of a larger facility. Especially when there are a lot of walls and floors for the signal to pass through. So how can organizations combat this problem to get an uninterrupted signal in all areas of their facilities? The answer lies in the installation of distributed antenna systems (DAS) from In-Building Cellular.

How Does Distributed Antenna Systems Work?

Rather than using a single antenna to distribute the wireless signal, a DAS installation involves placing multiple antennae at strategic locations throughout the facility. Because of the overlap between the antennae, the signal comes from multiple sources and is less likely to be disrupted or weakened by passing through various structures and obstacles. The result is a stronger, more consistent signal in more areas than with a single antenna.

How Is DAS Installation Beneficial?

Using a DAS solution has a host of benefits for the organization employing it, including:

  • Improved on-site networking
  • Better control of bandwidth
  • Provides connection access to unwired areas
  • Reliable in-building cellphone coverage
  • Fewer "dead zones"
  • More satisfied clients, employees, and guests

What is the signal path of a DAS?

  • Signal Source - Service provider (DAS, though powerful, is incapable of producing a standalone signal)
  • Donor Antenna - This antenna receives the incoming signal from the service provider and transfers the signal to the POI Tray.
  • POI Tray - Collects and combines RF signals
  • Head-End Unit - Provides further signal filtration and amplification based on signal frequencies.
  • Radio Units - Receive signals from the head-end unit, segregate based on frequencies, amplify them, and transmit them to nearby regions through antennas.

All of these signals are transferred through fiber optic cables which are low in signal attenuation, so there is no/very little signal loss or loss of signal gain even when placed at a great distance from the carrier feed. These are the basics of a distributed antenna system, however, depending on the industry and individual situation, these systems can change in complexity. Generally speaking, these are the basics of how a DAS will work. Contact us today to see how a DAS can benefit your business, facility, home, or other application.
