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 |
20110009085 | E911 Services Using Distributed Nodes - Distributed node systems and methods provide emergency call services to users indoors. A distributed node can be located in a building and configured to receive call requests from users in the building. The distributed node can transmit call requests to a central node that relays the call requests to a wireless network. The distributed node can also transmit node identifying information with the call request, which may be relayed to the wireless network. The wireless network can determine that a call request is a request for an emergency call and obtain location information and emergency services provider routing information based on a node identifier. The wireless network can transmit the location information to the emergency services provider using the emergency services provider routing information and set up the requested call. | 01-13-2011 |
