Cellular DAS

Indoor & Outdoor DAS

Industry data shows that 80% of all wireless calls are made indoors. Seamless indoor wireless coverage is essential in today’s environment. Indoor DAS (Distributed Antenna Systems) is a common solution for malls, stadiums, public halls, and other buildings. Outdoor DAS applications use essentially the same technologies; popular applications include open-air public spaces, stadiums, university campuses, and urban areas.

A DAS amplifies and distributes cellular and/or two-way public safety radio signals throughout areas that otherwise experience poor service. These systems are designed to enhance wireless signals in any combination of indoor and outdoor areas, with the end purpose of providing better cellular and two-way radio service in key areas.

The services carried on the DAS can be fed by either a bi-directional amplifier (BDA) connected to an outdoor antenna (an “off-air” feed) or fed through a carrier-installed, dedicated signal source. In any case, the DAS will then distribute the signal throughout the target area on a series of antennas fed via a network of cable and/or fiber.

As part of turnkey service offering Communications Electronics designs, installs, commissions and maintains DAS for all types of facilities using carrier-grade equipment. In fact, we will even facilitate the agreements with each of the wireless phone carriers before building your system to ensure approval.

Small Cell Distribution

Distributed Antenna Systems (DAS) for mobile telephony have been evolving for years, beginning as a solution for simply providing coverage to underserved spaces but evolving into a solution that can provide dedicated voice and data capacity to targeted areas.

Historically, DAS solutions have distributed cellular signals by amplifying an off-air Bi-Directional Amplifier (BDA; typically used for smaller DAS installations) or conventional base station hardware that is used for macro sites (for larger DAS installations). Neither of these are ideal solutions in most cases: BDAs simply push the traffic from buildings onto the macro network, straining capacity and increasing interference in the network; macro base stations are very expensive, relatively large, and use far more power than typically necessary.

Enter the “Small Cell”. The term refers to a class of base stations that are cost-effective and require much less power. Initially, these were stand-alone items (e.g. femtocells, picocells) often used to provide service to a small targeted area, but today mobile operators are marrying them with DAS solutions to provide the best of both worlds – dedicated capacity at a relatively low cost of deployment. Today, Small Cells compete with traditional DAS architectures to provide mobility solutions to capacity-starved spaces.

Like any wireless technology, Small Cells are not the right solution in every case but they provide ample reasons to be considered. We would be happy to share our expertise and help you determine if these would be a fit for your wireless solution.
