A method wherein a message packet is received at a node in a 1st wireless communication system, wherein said 1st wireless communication system determines whether it is experiencing interference with a 2nd wireless communication system, and wherein said 1st wireless communication system takes action to reduce said interference. Reducing said interference might include reduction in signal strength, change in message coding, and other actions, in response to a set of selected interference thresholds. Different protocol effects might be changed in response to one or more said thresholds, with the effect that distinct wireless communication systems may operate in relatively close proximity with a minimum of interference.
