Abstract:
1. A method for supplying a location based service or location based application generated in an outdoor environment to a mobile unit positioned in an indoor environment, comprising the steps of: a) determining the mobile unit location by access point (AP)-based positioning; b) relaying data related to the mobile unit location through a distributed antenna system (DAS) to an external location server (ELS) by transmitting the data through a cellular communication link; c) providing the location based service or location based application generated in the outdoor environment from the ELS to the mobile unit; d) toggling the determining the mobile unit location from AP-based positioning to external network-based positioning when the mobile unit moves from the indoor environment to an outdoor environment; and e) toggling the determining of the mobile unit location from external network-based positioning to AP-based positioning when the mobile unit moves from the outdoor environment to the indoor environment, wherein the cellular communication link includes a cellular network coupled to the DAS through a base server.
