A Distributed Antenna System is a network of components that distributes wireless signals throughout a building from a central point. The system takes wireless signals, distributes them using a cabling infrastructure and transmits the signal through remote antennas to provide seamless wireless communications where you need it most.
What is the purpose of a DAS?
A DAS improves wireless in-building coverage for anyone who uses a cell phone, two-way radio (i.e. fire fighters and police officers) or a wireless LAN laptop.
Where can a DAS be useful?
Anywhere people need indoor wireless coverage. When it comes to wireless communications, your building is not your friend. The steel, concrete and leaded glass used in most large structures absorbs wireless radio signals. The strong outside wireless signal quickly becomes non-existent on the inside. Some environments that can benefit from a DAS include: airports, campuses, convention centers, high-rise buildings, trains, shopping centers and sporting arenas.
What wireless technologies does a DAS support?
Dependent on manufacturers, DAS can support many types of technologies ranging from 380 MHz to 5.8 GHz. Wireless applications include private security, public safety, paging, wireless telemetry, cellular, PCS and 802.11a/b/g.
