  • Publication number: 20150264617
    Abstract: Systems and techniques for managing interference in wireless networking environments. Stations waiting to transmit are controlled so as to avoid undue interference with transmitting stations—for example, by restricting the use of a higher CCA threshold or otherwise requiring deference. Low power transmitting stations may be identified so that a monitoring station will defer its transmission even if the transmitting station is not in the monitoring station's BSS. Alternatively or in addition, stations may be configured to manage behavior that has a higher interference potential—such as by restricting the duration for which a station may use a higher CCA threshold.

  • Patent number: 9137832
    Abstract: A provided apparatus is caused to direct establishment of a connection of the apparatus with a core network via a wide area radio access network (RAN), where the core network is coupled to an external network. The apparatus is also caused to select or receive selection of a local area network that is coupled to the same or different external network via one or more local gateways (L-GWs). The apparatus is caused to request selection of a L-GW of the one or more L-GWs from the core network via the wide area RAN, and in response, receive an identity of a selected L-GW. Further, the apparatus is caused to direct contact with the selected L-GW based on the identity, and establishment of a connection of the apparatus with the selected L-GW. The apparatus may thereby be connected to the external network via the local area network and selected L-GW.
