  • Publication number: 20050226273
    Abstract: A technique for multiple receiver aggregation that allows for multiple immediate responses of acknowledgements or block acknowledgements. The technique uses a spoofed network allocation vector (NAV) implemented within an aggregate's PLCP header to protect the aggregate and all of the immediate responses from multiple receivers. The immediate responses are scheduled, the information indicating the scheduled offset time and granted transmission duration for response of each receiver being included in the physical sublayer data unit (PSDU) headers within the aggregate.

  • Publication number: 20050165919
    Abstract: In accordance with one embodiment, an article of manufacture embodied in a computer-readable medium for use in a processing system for modeling configurations of a wireless local area network is provided. The article of manufacture includes a characteristic and configurations receiving logic for causing the processing system to determine a set of original characteristics and configurations of the wireless local area network. As well, a simulation logic for causing the processing system to simulate an outcome based upon a set of configurations in accordance with a goal. In other embodiments, the goal may be user defined or based upon historical data. Further, a configuration creation logic for causing the processing system to create a set of new configurations based upon the outcome and a management logic for causing the processing system to apply the set of new configurations to the wireless local area network are provided.

  • Publication number: 20050027840
    Abstract: A wireless local area network is disclosed which includes a plurality of wireless access points each having a predetermined coverage area, and a plurality of wireless clients for establishing a wireless link with at least one wireless access point. Some or all of the wireless clients are within the respective coverage areas of at least a portion of wireless access points. A load balancer is provided for balancing distribution of wireless clients among wireless access points. The load balancer includes a tracking implementation for tracking at least one telemetry parameter of each wireless client's wireless link with each respective wireless access point. A goal implementation is included for comparing one or more telemetry parameter against at least one predetermined goal to obtain a fitness measure.
