1. A method for reducing interference between neighboring wireless networks operating on channels with different bandwidths, comprising the steps of:
detecting, by a first device in a first network, interference from a device on a second network, wherein the said second network is operating on a channel band that forms a part of the channel band that the said first network operates on; constructing, by the said first device, an interference notification frame for notifying the presence of the said first network; broadcasting, by the said first device, on the channel that the said second network operates on, the said interference notification frame; protecting, by the said first device, the broadcast of the said interference notification frame from collision on the channels of both networks by precluding the said interference notification frame with transmission of appropriate protection frames on the channels of both networks; and detecting, by a second device in the said second network, the presence of the said first network upon receiving the said interference notification frame. |
