Submission March 2005 R. Aiello, C. Razzell, G. ShorSlide 2 MB-OFDM proposal update: Clarification of regulatory situation Roberto Aiello, Charles Razzell, Gadi Shor

doc.: IEEE /168r0 Submission March 2005 R. Aiello, C. Razzell, G. ShorSlide 3 Summary Freescale and Motorola claimed that MB-OFDM systems must transmit at reduced power The number one reason for voting against the MB- OFDM proposal was regulatory compliance MBOA-SIG worked diligently for two years at great financial expense to obtain clarification for the FCC –The mechanism for clarification was a waiver request FCC granted the MBOA-SIG waiver in March 2005 –MB-OFDM transmitters may tested under normal operation –MB-OFDM systems can transmit at full power –Gated measurement is waived

doc.: IEEE /168r0 Submission March 2005 R. Aiello, C. Razzell, G. ShorSlide 4 September IEEE /343r1 During the San Francisco IEEE meeting XSI made a presentation on FCC rules: Slide 3 of 03153r9P802-15_TG3a-XtremeSpectrum-CFP-Presentation.ppt –The issue today is NOT whether or not there is more or less interference –The issue is, what are the rules. Side interest is WHY did NTIA and FCC specifically write rules for frequency hoppers Slide 5 from 03153r9P802-15_TG3a-XtremeSpectrum-CFP-Presentation.ppt; XSI claimed that MB-OFDM needs to reduce its transmit power by 4.7 dB to be FCC compliant, MB-OFDM should transmit at -46 dBm/MHz (instead of dBm/MHz) 3168 MHz 3696 MHz 4224 MHz 4752 MHz Time Band-3 Band-2 Band-1 Band-2 Avg Pwr = 1/3 of “hopping-on” Power

ShorSlide 5 Waiver Highlights Waiver is granted Waiver broadly accepts in situ compliance testing for all indoor/handheld UWB systems –All tests to be done with hopping, sequencing, or gating as the system will be used in practice –Exception for now: MHz Waiver in force until FCC finalizes rule- making proceeding on these issues

doc.: IEEE /168r0 Submission March 2005 R. Aiello, C. Razzell, G. ShorSlide 6 Conclusions The FCC agrees with the MB-OFDM SIG Motorola and Freescale requests for denial of the waiver were not accepted The FCC ruling eliminated the #1 reason stated for voting against MB-OFDM Your vote for MB-OFDM is requested!
