2. doc.: IEEE 802.15-01/158r0 Submission March, 2001 Tod Sizer, Lucent Technologies / Bell LaboratoriesSlide 2 Coexistence Working Group Charter Work within the Bluetooth community as well as with cross industry groups (e.g. IEEE) to quantify the detrimental effects which Bluetooth and other wireless products will have on the performance of both. This information will be imperative for members of the Bluetooth community to advise their customers of the realistic performance one can expect in different environments as well a build products which span between Bluetooth and other wireless products. In addition, it will be used to disseminate SIG sponsored information on issues of coexistence to regulatory bodies. Develop methods of Bluetooth operation that will be used to improve coexistence between systems in the shared radio band. These will be issued as Best Practices white papers, improvements to the Bluetooth specifications, or formal profiles as necessary. To work closely with the Radio 2.0 Working Group to evaluate coexistence issues in new proposed radio designs.

We are interested in more interactions in the areas: –Coexistence Mechanisms –MAC layer simulations (esp. with new coexistence mechanisms employed)
