3. 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

4. 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.

7. 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

8. 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.
