Abstract
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.
