Distributed Antenna Systems – What they are and Why Companies Need Them.

During the September 11th attacks, EMS personnel discovered that communication systems and protocols that distinguished each department were hampered. A lack of interoperability, overwhelm from simultaneous communication, and damaged network infrastructure from the attack were making effective and efficient EMS communications extremely difficult.

As a result, state and local building authorities have been mandating a solution to ensure this never happens again. Public safety wireless systems or Distributed Antenna Systems (DAS) are being installed into new and existing commercial structures to ensure EMS responders have continuous communication.

What is a Distributed Antenna System?

Distributed antenna systems (DAS) are a network of unobtrusive antennas throughout a building, which produce a world-class quality of wireless radio service. Think of it like a radio tower inside of a building that is powerful, secure, and reliable. There are many benefits, but for an EMS responder, it means they will have a much needed reliable communication system for continuous operation during fires, floods, and other emergencies.

How do Distributed Antenna Systems Work?

A DAS is a network of antennas that are sending and receiving signals on a carrier’s frequency, which results in improved voice and data connectivity for end-users. A DAS has two primary components:

  • Signal Source – As the name implies, a DAS “distributes” signals. But it doesn’t generate the signal. A DAS needs to be fed a signal from a source. The four most common sources are off-air (via an antenna on the roof), an on-site BTS (Base Transceiver Station), and small cells.
  • Distribution System – Once the signal is received, it’s distributed throughout the building. There are four main types of distribution systems – active (using fiber optic or ethernet cable), passive, hybrid, and digital.

Benefits of Using a Distributed Antenna System  

  • More Coverage
  • Better Coverage
  • Consistent Coverage
  • Fewer Coverage Holes
  • Reduced Power Use

Who Can Benefit from a Distributed Antenna System?

  • High-rise Buildings
  • Shopping Malls
  • Health Care Facilities
  • And More

Need a Distributed Antenna System for Your Building?

Communications Solutions, Inc. is offering CommScope’s DAS systems, in Jacksonville and the Northeast Florida area, which are designed to be flexible, scalable, and efficient. CommScope offers end-to-end wireless solutions like their ION-E and ION-U systems that support multiple operators, frequencies, and technologies. They feature plug-and-play simplicity that easily speeds and scales your most complicated hardware deployments.

ION-E is an all-digital system that runs on economical Category 6A and fiber-optic cables. ION-E’s simplicity and IT-friendly deployment make it ideal for enterprise buildings.

ION-U combines low and high power DAS technology to cover large indoor spaces, sprawling outdoor spaces, or both. ION-U’s range and capacity make it the preferred choice for airports, stadiums, and other large venues.
