Abstract:
Methods and systems for mobile phone location within a digital distributed antenna system (DAS) are provided. In one embodiment, a method comprises: receiving a request for location services from a subscriber unit located within a digital DAS, the digital DAS including a first partition of bandwidth for transporting digitized RF signals of one or more modulated signals and a second partition of bandwidth for an Ethernet pipe transporting IP formatted data; routing the request for location services to a subscriber locator center; instructing locator receivers within a geographical area of the digital DAS to listen for a signal from the subscriber unit; listening for the signal at a first locator receiver; when the signal is observed, recording a time the signal was received and generating subscriber unit ranging data; and transmitting subscriber unit ranging data back to the subscriber locator center in an IP formatted message via the Ethernet pipe.
