Distributed Antenna System Basics



Distributed Antenna Systems, or DAS, as they are frequently abbreviated, are networks in which separate antenna nodes provide wireless service. This is in contrast with a single, larger antenna node providing service to the same area. DAS provide increased reliability, as a single outage only leads to a partial loss of coverage, as illustrated in the graphic above. Along with increased reliability, DASs operate on reduced overall power consumption, as each separate node requires substantially less energy than a single, larger node.
