System and method for location of mobile devices in confined environments
First Claim
1. A distributed antenna system, comprising:
- a master unit;
a plurality of remote units in communication with the master unit; and
a plurality of sensors in a sensor network, the sensors associated and co-located with respective remote units, each sensor of the plurality of sensors including;
a controller;
receiver circuitry configured for receiving signals from a device that is remote to the sensor and respective remote unit;
the controller configured for using the received signals to determine position information for the sensor and respective remote unit;
the receiver circuitry of a sensor including an RF receiver integrated with a respective remote unit and operable to receive RF signals from mobile devices for providing RF communications in the distributed antenna system.

Abstract
The sensor network may include a location capture processing unit; and a plurality of sensors in communication with the location capture processing unit. Each sensor of the plurality of sensors includes a controller and a RF receiver configured to receive RF signals. The RF receiver is in communication with the controller. A localization engine is configured to receive beacon signals transmitted by other sensors in the sensor network. The localization engine is in communication with the controller. The controller of each of the plurality of sensors is further configured to determine a position of its respective sensor using either RF receiver or localization engine or both. The plurality of sensors communicates their position to the location capture processing unit.
