This page will provide links to the candidate Coexistence Mechanism proposals that are contributed to TG2. Again, there are two classes of Coexistence Mechanisms: Collaborative and Non-Collaborative Mechanisms. If it is possible for the WPAN™ and the WLAN to exchange information between one another then it is possible to develop a Collaborative Coexistence Mechanism where the two wireless networks negotiate to minimize mutual interference. If there is no method to exchange information between the two wireless networks then you can use a Non-Collaborative Coexistence Mechanism. Submissions of both types of mechanisms are encouraged. Depending on the operating environment one technique may be preferred over the other.

Session #12/Orlando Update: The Task Group selected -01/252r0 as the Adaptive Frequency Hopping Non-Collaborative Coexistence Mechanism. The Task Group voted to drop the Transmit Power Control in the 802.11 Non-Collaborative Mechanism since it is being handled in 802.11h. There is interest in pursuing the Data Rate Scaling Mechanism if we find resources to work on it.
