  • Patent number: 9014727
    Abstract: A mobile device communicates position samples of one or more reference position with respect to one or more other communication device such as access points to a location server communicatively coupled to a reference database. The location server determines whether to utilize the one or more reference position in the reference position database based on the communicated samples. The mobile device scans the position samples, which indicate position information of the one or more other communication device and/or whether the position information is reliable for use. The scanned position samples are accumulated and transmitted to the location server. The location server updates records for the one or more reference positions with respect to the one or more other communication device in the reference position database based on the accumulated position samples received. The updated records are utilized to determine a fast position fix for the position device.

  • Publication number: 20150089029
    Abstract: A system and method supporting the automatic conversion of multimedia information from a first format to a second format in a broadband access gateway and/or network-based server are disclosed. The broadband access gateway and/or network-based server may convert multimedia information that is in a format that an access device is not capable of processing. The gateway and/or server may automatically detect the format incompatibility, and may automatically convert or arrange for conversion of the multimedia information to a format that is compatible with the access device, based upon compatibility information associated with the access device. The conversion may be based upon a set of user-defined quality of service criteria, and may be subject to the control of digital rights management parameters associated with the requested multimedia information.

  • Patent number: 8983472
    Abstract: A method and system supporting handoff of a multimedia call session using background network scanning is disclosed. A mobile multimedia handset may engage in the exchange of a multimedia information stream via a first wireless network, and may sniff a portion of radio frequency spectrum for a second wireless network. Information about available services and network quality of service for the second network may be received by querying the second wireless network or from advertising by the second wireless network. Hand-off between the two networks may be based upon the results of the comparison and one or more user-defined criteria, and the handoff may be synchronized according to predefined events in the stream of multimedia information.

  • Patent number: 8964895
    Abstract: A wireless local area network (WLAN) transmitter includes a baseband processing module and a plurality of radio frequency (RF) transmitters. The processing module selects one of a plurality of modes of operation based on a mode selection signal. The processing module determines a number of transmit streams based on the mode selection signal. The processing of the data further continues by converting encoded data into streams of symbols in accordance with the number of transmit streams and the mode selection signal. A number of the plurality of RF transmitters are enabled based on the mode selection signal to convert a corresponding one of the streams of symbols into a corresponding RF signal such that a corresponding number of RF signals is produced.
