Additional Task agreed to at the May 2009 Wireless Interim There is recognized value in assessing the feasibility and performance of multiple 802 wireless technologies coexisting in the TV white space and make recommendations to the working groups The SG plans the following tasks Evaluate how well the unaltered 802 standards would coexist in TVWS Receive and review contributions on possible coexistence mechanisms for operation in the TV white space Receive and review contributions on the complexity and effectiveness of the various coexistence mechanisms Provide procedural recommendations to the EC on coexistence in the TVWS Provide technical recommendations, to the working groups considering MAC/PHY projects in the TV white space, on what features could be supported in the drafts to enable coexistence between 802 wireless standards in the TV white space Request and review feedback from the WGs on these recommendations Work with the WGs on incorporating these coexistence mechanisms into the drafts Slide 8 Eldad Perahia (Intel)

Schedule for Additional Deliverables May 2009 Schedule for Additional Deliverables May to July Conference Calls Announce to WGs our plan to develop a document on recommendations to the WGs on coexistence mechanisms in the TV white space Receive and review contributions on how well unmodified 802 standards would coexist in the TV white space Receive and review contributions on possible coexistence mechanisms July Plenary Receive and review presentations on the complexity and effectiveness of the various coexistence mechanisms Select which coexistence mechanisms to recommend to the working groups Request an extension of the study group until November July to September Conference Calls Prepare and review a document with recommendation on features required in the drafts to support the recommended coexistence mechanisms September Wireless Interim Review and approve the document with the recommendations for the working groups Deliver the recommendation document to the working groups November Plenary Review feedback from the working groups Slide 9 Eldad Perahia (Intel)

May 2009 Future Work After completion of the current tasks the Study Group will consider other tasks Possible future deliverables Coexistence metrics document Incumbent protection document Recommendations to the Executive Committee Development of a PAR on coexistence in the TV white space Other recommendations If needed the study group will request an extension after the November Plenary The current plan is to request an extension at the July plenary Slide 10 Eldad Perahia (Intel)
