Progress of Japanese Committee July 2007 Progress of Japanese Committee Shigeru Fukunaga OKI Shigeru Fukunaga, OKI

July 2007 Abstract We have discussed the 950 MHz regulation in informal meetings since February. Short carrier sense for LR-WPAN Channel allocation for sub carrier RFID systems Formal committee of MIC was restarted in July. Shigeru Fukunaga, OKI

MIC committee Date: 5th July 2007 Conclusion Final draft of regulation was proposed, and discussed. There was no objection for LR-WPAN. Only one proposal of miner change There were some comments for regulation of sub carrier RFID systems. Draft of final report was reviewed. Almost all parts of LR-WPAN were finished. We will get consensus in next committee. Shigeru Fukunaga, OKI

Draft of Regulation for LR-WPAN (1/3) July 2007 Draft of Regulation for LR-WPAN (1/3) Same to Montreal meeting Maximum power 1mW, 10mW Frequency band 1mW: 950.8 – 955.8 MHz 10mW: 954.0 – 955.0 MHz In Progress 1mW 10mW Shigeru Fukunaga, OKI

Draft of Regulation for LR-WPAN (2/3) July 2007 Draft of Regulation for LR-WPAN (2/3) Same to Montreal meeting Signal bandwidth Less than (200×n) kHz (n: number of unit channels, n=1,2,3) Channel mask In Progress 1mW 10mW -39ｄBm/100kHz -20dBm fc -20dBc 200kHz fc-200kHz 0dBm -26dBm/200kHz fc+200kHz -39ｄBm/100kHz -10dBm fc -20dBc 200kHz fc-200kHz 10dBm -18dBm/200kHz fc+200kHz Shigeru Fukunaga, OKI

Draft of Regulation for LR-WPAN (3/3) July 2007 Draft of Regulation for LR-WPAN (3/3) Carrier sense level: -75dBm Carrier sense time: 10ms Exceptional rules ch1 – ch6, ch21 – ch24 128 us (in case of less than 10% duty ratio) No carrier sense (in case of less than 0.1% duty ratio) ch7 – ch20 & in case of response signals Transmission control After sending less than 1s, it has to pose more than 100ms. In Progress Shigeru Fukunaga, OKI

Draft of Regulation for RFID July 2007 Draft of Regulation for RFID Two specific channels will be defined for sub carrier RFID systems. RFID reader/writer does not need carrier sense. In Progress 954MHz 952MHz 30dBm -39dBm/100kHz 955MHz 10dBm 950MHz -29dBm/100kHz 0dBm 952.2 (ch7) 952.4 (ch8) 952.6 (ch9) 952.8 (ch10) 953.0 (ch11) 953.2 (ch12) 953.4 (ch13) 953.6 (ch14) 953.8 (ch15) 954.0 (ch16) 954.4 (ch18) 954.6 (ch19) 954.8 (ch20) 955.0 (ch21) 955.2 (ch22) 955.4 (ch23) 955.6 (ch24) 954.2 (ch17) 951.0 (ch1) 951.2 (ch2) 951.4 (ch3) 951.6 (ch4) 951.8 (ch5) 952.0 (ch6) -20dBm/100kHz -10dBm/100kHz 950.8MHz 956MHz 955.8MHz -55dBm/100kHz Shigeru Fukunaga, OKI

Future procedures in MIC July 2007 Future procedures in MIC Final consensus in next committee Approval of parent committee Release of formal draft of 950MHz regulation after parent committee Public comment for one month Some procedures in MIC for more than 4 months Amendment of ministerial ordinance Shigeru Fukunaga, OKI
