Distributed antenna system information


A diagram contrasting a single antenna configuration with DAS
A typical DAS node for the Videotron 3G network in Montreal, Quebec
DAS deployed by Transit Wireless in New York City Subway to provide WiFi, cellular voice and data coverage. The RF node with three antennas was at the platform and another antenna near the stairs on the far side.

A distributed antenna system (DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level, and node installations are compact. A distributed antenna system may be deployed indoors (an iDAS) or outdoors (an oDAS).[1]
