About Distributed Antenna Systems (DAS)

As wireless technology has become more commonplace, users are demanding connectivity in every venue, including challenging environments like dense indoor structures such as high-rise buildings, arenas, tunnels, airports and across large outdoor stadiums and campuses. Individuals, businesses and public safety professionals require uninterrupted access to voice and data – no matter where they are. Because construction techniques and materials can block or degrade internal and external wireless communications, a Distributed Antenna System (DAS), consisting of many antennas tuned to precisely match the areas of a building or venue can help boost service. DAS can be used to extend wireless coverage within structures and enable radios and cell phones to work regardless of their position within the building.

As more buidings are constructed to LEED or other high energy efficiency standards dictated by local building codes, a challenge has arisen to in-building wireless connectivity. Distributed Antenna Systems or DAS wireless systems are instrumental in overcoming the radio-frequency (RF) issues associated with LEED or "green" buildings. One significant challenge created by the design and materials criteria is in-building wireless connectivity. The same qualities that meet LEED standards are contrary to the dissemination of adequate radio frequency (RF) signals. Low emissivity glass makes windows more energy efficient but effectively blocks RF signals. That very desirable energy saving also creates in-building cellular issues. DAS wireless systems can help.
