Abstract
A method is provided for accommodating periodic interfering signals in a wireless network. In this method, a network scans a transmission medium to locate any interfering signals. If it finds interfering signals, the scan determines their period, and the network alters the period of its superframes such that: either the period of the superframes is equal to the period of the interfering signals; the period of the superframes is an integer multiple of the period of the interfering signals; or the period of the interfering signals is an integer multiple of the period of the superframes. The network then alters the position of the superframes relative to the position of the interfering signals to arrange things such that no portion of the interfering signal interferes with a superframe beacon, such that that a maximum amount of contiguous channel time is provided in each superframe, or both.
