Distributed Antenna Systems: DAS in a Nutshell

June 11, 2014 at 5:17 pm  •  Posted in das  •  0 Comments

Today’s wireless users expect (and often need) to communicate everywhere they go, from parking garages to elevators, and everything in between. Here are a few stats to drive the point home:

  • 200,000 text messages are sent every second, worldwide
  • Average smartphone usage grew 81% in 2012
  • 80% of all worldwide data connections initiate inside a building

In true zombie-like fashion, most of us are cemented to our devices round the clock. (I’m often guilty of this.) While many Americans want 24/7 coverage, some need it. For first responders and healthcare professionals, swift communication saves lives.

In this blog post, I’ll give you a brief overview of Distributed Antenna Systems (DAS), a few applications for DAS, and info on how Graybar can help. Keep reading for more.

Distributed Antenna Systems (DAS) in Action

In laymen’s terms: DAS was designed to expand wireless coverage within and between structures, allowing cell phones and radios to function, regardless of position. DAS distributes cellular coverage through a system of cables and antennas, breaking through structural obstacles and heavy-duty building materials like steel and concrete.

There are a wide range of wireless services supported by DAS, from cellular phones, to public safety radios, and wireless medical telemetry services, to name a few. Here are a few real-world applications for DAS:

1. Business Applications

Did you know that some eco-friendly building materials can interfere with wireless and data signals?

Let’s say you’re a contractor building a brand-new conference center, or even a hospital. A well-functioning Distributed Antenna System is crucial to the success of both of these organizations. The conference center will need reliable coverage for conference attendees to do business, and the hospital will need top-notch coverage for quick communication and access to patient information. Both buildings need the proper bandwidth to enable data transfer, and certain building code may even require it. Clients and end-users demand reliable wireless coverage, and smart contractors are wise to this need.

2. Public Safety & First Responders

First responders depend on reliable communication to keep the public safe.

Blocked radio reception is a big problem, and could mean the difference between saved vs. lost lives. The events of 9/11 reinforce the necessity for reliable coverage at all times, regardless of location. First responders like firefighters, paramedics, and police keep us safe. Let’s help them do their job with Distributed Antenna Systems that work when it counts.

3. Hospitals & Healthcare

Healthcare facilities are an environment that demands reliable coverage. Lives depend upon it.

Healthcare workers need to communicate and access patient information, and quickly. In the hospital, every second counts. Lead-lined X-ray rooms, glass shielding, and metal and concrete create unreliable RF (radio frequency) coverage. Distributed Antenna Systems are crucial to overcoming coverage hurdles in hospitals and healthcare facilities.
