20110148709 | SIGNAL PATH DELAY DETERMINATION - Propagation time for a target signal path is determined by detecting and processing a plurality of unknown signals received at two locations. A third location is established, such that the propagation time between the third location and one of the two locations is known, and the signal path between the third location and the other of the two locations is the target signal path. The two locations are monitored for any signals that may be detected. Signals received at the two locations are processed to determine which signals have a common source, and of the signals having a common source, the signal having the greatest delay between times of reception at the two locations is selected. The selected signal is used to determine the propagation time between the two locations. | 06-23-2011 |
20120046048 | SYSTEM AND METHOD FOR PROVIDING LOCATION INFORMATION FOR A MOBILE HANDSET - A system that facilitates determination of a location of a mobile handset. The system includes three or more location measurement units that each correspond to a sector of the cell site. The location measurement units transmit location related information to a computation component.

20100112996 | REMOTE ELECTRICAL TILTING ANTENNA SYSTEM MEASUREMENT VIA DOWNLINK ANTENNA - A technique for operating an antenna system includes using a downlink antenna to provide radio frequency information to a central antenna controller and adjusting operating parameters of the antenna system based thereon. In at least one embodiment of the invention, an apparatus includes a central antenna control facility configured to communicate at least one operation parameter to a first antenna facility associated with a first antenna in a first cell coverage area. The at least one operation parameter is determined at least partially based on information associated with a signal received from the first antenna by a downlink antenna in a second cell coverage area. | 05-06-2010 |
20100151907 | SHARING ANTENNAS FOR INCREASED MULTIPLE-INPUT UPLINK RECEPTION - The claimed subject matter facilitates sharing antennas among carriers co-located at a base station such to increase throughput of the individual carriers. Thus, the carriers can effectively receive multiple-input/multiple-output (MIMO) from mobile devices though the individual antennas of the carrier alone are not sufficient to receive such signals. A co-sharing interface is provided that takes signals from antennas of one carrier and forwards the signals to a second co-located carrier. In this regard, a carrier can receive signals from a related set of antennas as well as the co-sharing interface component (from a set of antennas related to a disparate carrier) and process the signals in conjunction. Thus, the signals can be disparate portions of a MIMO signal. In addition, the co-sharing interface can modify the signals as defined by the carrier receiving the signals from the interface, such as by applying gain control, alarming, bypass circuitry, and/or amplification. | 06-17-2010 |

20140155095 | Enhanced Location Based Services - Location information (e.g., GPS information) pertaining to the location of a device may be integrated into a distributed antenna system (DAS) to enhance location based services. This may be accomplished via a system that filters and combines GPS information with DAS information. Utilization of the enhanced location based services system may enhance accuracy performance of indoor location services and improve round-trip time (RTT) location responses associated with network assisted GPS (e.g., A-GPS) location requests for services from indoor calls. | 06-05-2014 |
