Small Cell Distributed Antenna Systems

Distributed Antenna Systems (DAS) provide a way to efficiently distribute wireless connections inside buildings or other structures where steel columns and layers of concrete can interfere with wireless signals. Cellular coverage supplied by antennae is often not sufficient to provide reliable coverage for building interiors. A supplemental, in-building system such as a distributed antenna system, or DAS is often required to provide service and to deliver a reliable cellular signal throughout the structure or across multiple buildings. A distributed antenna system is a solution to the question, “Why does my cell phone quit working when I go into this building?”

The use of a DAS will allow indoor facilities to provide cellular coverage in previously unreachable areas.  As more new buildings are constructed to Leadership in Energy and Environmental Design (LEED) certification standards or other energy efficient building standards required by local building codes, cellular dead zones within buildings have become more prevalent.  The thicker walls and Low-E glass windows save energy, but can also block cellular signals from coming into the buildings presenting a challenge to cellular service quality. 

Public safety personnel utilize wireless communication systems in buildings when responding to police, fire and rescue calls.  Ensuring indoor cell coverage in elevators, stairwells, basements, tunnels and parking structures is an important reason to use a DAS.

Optical Telecom has experience in DAS installations in challenging venues such as secure facilities, underground and tunnel systems as well as large arenas, office buildings, historic buildings and convention centers.  Please contact us for more information.
