  • Patent number: 7555301
    Abstract: A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. In one embodiment, channel allocation techniques for increasing one or more of throughput and coverage in a wireless communications environment.

  • Publication number: 20080186933
    Abstract: An approach for providing wireless network services using a WAP group includes establishing a WAP group that represents a logical grouping of WAPs. Communications between WAPs in the WAP group and clients are performed using a shared BSSID. One of the WAPs in the WAP group is designated as a master WAP and the other WAPs in the WAP group are designated as slave WAPs. The master WAP assigns WAPs in the WAP group to provide wireless networking services to clients. The assignment is performed based upon the performance of communications channels used to carry communications between the clients and the WAPs in the WAP group and current loads of the WAPs in the WAP group. The assignments may be dynamically changed over time, based upon changes in the performance of the communications channels and/or changes in WAP loading.

  • Publication number: 20080186932
    Abstract: According to an approach for mitigating the effects of rogue WAPs in wireless local area networks, a determination is made of one or more clients that are communicating with a rogue WAP. For example, messages may be intercepted and examined to identify messages that are sent by or to rogue WAPs. Information that identifies the one or more clients is then extracted from the messages and stored in a client list. Communications between the one or more clients and the rogue WAP are then disrupted. Embodiments of the invention include, without limitation, disrupting communications using deauthentication and by spoofing Address Resolution Protocol (ARP) responses.

  • Publication number: 20080020801
    Abstract: To manage a group of wireless base stations (WBS), a network administrator accesses one of the WBS, which serves as the management point. The management point WBS distributes parameters to each WBS to configure each WBS. Each WBS has logic thereon to that allows the WBSs to discover one another and self-organize into one or more clusters of WBSs. The WBSs cooperate to select one of the WBS as a master of each cluster. Furthermore, the logic on each WBS provides for a failure mechanism such that if the master becomes inoperable, another WBS is promoted to master. These self-organized clusters of WBSs collaborate to provide a variety of services, such as fast handoff of client devices, load balancing, and rogue device detection/mitigation. Based on the foregoing, there is no single point of failure.
