Patent ID: 8004975

Claim:
A method of providing adjacent channel interference avoidance in a wireless network including a plurality of nodes, the wireless network having a control channel and at least one data channel, the method comprising: defining two sets of Radio Frequency (RF) channels used by the wireless network, the first set having at least one channel and the second set having a plurality of channels, and wherein said first set and said second set have mutually non-adjacent channels; designating a channel in said first set as the control channel, said control channel being non-adjacent to channels in said second set, said control channel used by all nodes of said wireless network; and utilizing said channels of said second set as data channels for data transmissions by all nodes of said wireless network, and wherein a multi-radio node having more than two radios refrains from reserving a data channel if the node is transmitting on said node's adjacent channel on another collocated radio, and a multi-radio node having more than two radios does not accept a request for a data channel if the node is receiving on said node's adjacent channel on another collocated radio.
