US Patent 7082320 Integration of wireless LAN and cellular distributed antenna

A system and method for supporting wireless in-building communications uses a wireless local area network access point, a cellular distributed antenna system, and a cellular radio base station coupled to the cellular distributed antenna system. The cellular radio base station provides cellular communication service via the cellular distributed antenna system. A coupler couples the wireless local area network access point to the cellular distributed antenna system in reverse mode, such that the wireless local area network access point provides wireless local area network service via the cellular distributed antenna system.
