Abstract

A method for operating a plurality of different wireless networks operating at least in part in overlapping frequency bands includes monitoring, by a first wireless transmitter, activity in the overlapping frequency bands. The first wireless transmitter determines whether a channel in the overlapping frequency bands is idle for a predefined time period. Based on the channel being idle for the predefined time period, it is determined that the first wireless transmitter has a transmission opportunity on the channel. The first wireless transmitter measures an amount of time until a next frame boundary on the channel and, based on the amount of time until the next frame boundary being below a threshold, reserves the channel for a fixed duration of time. Based on the amount of time until the next frame boundary being above the threshold, the first wireless transmitter skips the transmission opportunity on the channel.
