Abstract:
1. A method of a wireless access node within a network characterizing uncoordinated interference, comprising: the wireless access node collecting air-time usage history at the wireless access node, comprising the wireless access node receiving and monitoring signals over time that are greater than a threshold; the wireless access node receiving air-time usage history of at least one neighboring wireless node, wherein the air-time usage history of the at least one neighboring wireless node is obtained by the at least one neighboring wireless node monitoring over time, signals received by the at least one neighboring node greater than a threshold; the wireless access node estimating an impact of uncoordinated interference, comprising comparatively analyzing the collected air-time usage of the wireless access node and the received air-time usage of the at least one neighboring wireless node, comprising synchronizing the collected air-time usage of the wireless access node and the received air-time usage of the at least one neighboring wireless node, and generating a histogram of available air-time based on the comparative analysis; and the wireless access node identifying gaps of the available air-time based at least in part on the comparative analysis, and increasing its transmission bit rate and number of transmitted data packets during the identified gaps.
