Consistent Comparison Information
It would help voters to easily see how proposals compare
Based on Criteria document (03/031r9)
Range, Implementation complexity, Multiple Piconet Support, Regulatory Approval, Etc.
Propose a subcommittee to prepare a comparison matrix for presentation at the beginning of the July meeting.
Process is to use conference calls or set up an ad hoc for presenters to contribute to the summary matrix.

Patent Policy
All proposers agree to adhere to the IEEE Patent Policy:
The Patent Holder is prepared to grant a license to an unrestricted number of applicants on a worldwide, non-discriminatory basis and on reasonable terms and conditions to comply with the [Proposed] IEEE Standard.
The Patent Holder is prepared to grant a free license to an unrestricted number of applicants on a worldwide, non-discriminatory basis to comply with the [Proposed] IEEE Standard.

7. May 2003
Regulatory Approval
All proposals adhere to the current FCC rules regarding operation of UWB systems between 3.1 and 10.6 GHz.
Most proposals also have provisions for modifying their spectrum usage to account for worldwide regulatory rules still being developed in Europe and Asia.
John Barr/Gregg Rasor, Motorola, Jim Allen, Appairent

8. May 2003
Use of the MAC
All proposals assume that the MAC will be used.
Some proposals required no changes
Some proposals require specific PHY support modifications
Additional MAC changes not required to support a particular PHY should be addressed as a separate addendum.
