November 2003 Tim Wakeley – HP, et al Slide 2 doc.: IEEE 802.15-03-0497r0 Submission Comments on Nortel Document Document Abstract –Suggests that FCC UWB regulations be modified to protect 802.11 devices 802.15.3a Initial Comments –802.11 and 802.15 are both part 15 devices –IEEE should not ask FCC for special protection for some classes of unlicensed devices –We agree with FCC rules and should allow the IEEE to develop proper coexistence rules between its standards through 802.19 –802.15.3a is aware of other licensed and unlicensed services and is designing for coexistence and interference mitigation –We do not want to restrict future UWB applications
