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 from the FCC
The mechanism for clarification was a waiver request
FCC granted the MBOA-SIG waiver in March 2005
MB-OFDM transmitters may be tested in normal operational mode
MB-OFDM systems can transmit at full power
Gated transmissions may also be measured with gating active

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)

5. Waiver Highlights Waiver is granted
March 2005
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
R. Aiello, C. Razzell, G. Shor

6. Conclusions The FCC agrees with the MB-OFDM SIG
March 2005
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!
