    摘要: The principles of the present invention provide for providing contention free quality of service to wireless stations. A station indicates to an access point that higher priority data (e.g., time constrained data) is to be sent to the access point. The access point receives the indication and selects a slot time for the station based on the number of other stations that have also indicated higher priority data. A slot time is selected such that the station can check for access to a common wireless link before any stations with lower priority data (e.g., data without time constraints). The access point sends the selected slot time to the station and the station receives the slot time. When the station receives an indication that an application has higher priority data to send, the station checks the common wireless link for availability at the selected slot time.

    摘要: Described is a determination of whether interference in a wireless network has achieved a threshold level that adversely impacts communication bandwidth. If so, action is taken to mitigate the effects of the interference and thereby improve the bandwidth. The action that is taken may be in the form of at least one mitigation solution, including mitigating by packet fragmentation, mitigating by changing the wireless network's current operating frequency, mitigating by changing a power level, mitigating by transmit dodging, and/or mitigating by pre-selecting at least one transmission criterion based on an observed pattern. A framework is provided to coordinate mitigation of interference-related problems, and includes an interferer decision mechanism that receives RF interference related-data and evaluates the interference data against a threshold. Mitigation is employed when the threshold is achieved on the current operating frequency.
