Using Distributed Antenna Systems to Extend WLAN Coverage

—Many of the WLAN hotspots are significant in size and achieving good coverage may be challenging. The current standard for providing coverage is to distribute individual WLAN access points in the target area. Due to the fact that the in-building environment has many challenges, such as walls and elevators, the number of access points needed by using this method may become significant. There are several benefits of implementing the WLAN over a distributed antenna system (DAS). For example, the WLAN coverage and capacity can be improved and the coverage area can be shaped in a more efficient way. Furthermore, the integration of WLAN with the existing cellular DAS will reduce hardware and related installation cost and services dramatically compared to two stand-alone networks.
