6. Submission May, 2010 Masashi Shimizu NTT doc.: IEEE 802. 15-10-0304-01-004f User requirements 433MHz can be use just international logistics. It means user or this products will be limit for international logistics companies. Low cost High reading rate Automatic Identifying the container number Seal monitor function

7. Submission May, 2010 Masashi Shimizu NTT doc.: IEEE 802. 15-10-0304-01-004f Data rate limit by using market available LSI (SI4421) 38.4Kbps BFSK Deviation 30KHz makes 180.5KHz bandwidth

8. Submission May, 2010 Masashi Shimizu NTT doc.: IEEE 802. 15-10-0304-01-004f SIPG Container Yard A 300m radius cell is assumed. One island block is composed of 40X6X6 containers. One reader can cover 8 islands. This means there are 11520 containers in a cell maximum.

9. Submission May, 2010 Masashi Shimizu NTT doc.: IEEE 802. 15-10-0304-01-004f Estimated Reading time of 10000 Tags in a Cell Beacon Interval PA Pure ALOHA CS -100 CSMA With -100dBm sensitivity CS -110 CSMA With -110dBm sensitivity TX time: 10mSec 38.4Kbps 384bit payload including Preamble and CRC

10. Submission May, 2010 Masashi Shimizu NTT doc.: IEEE 802. 15-10-0304-01-004f Results 38.4Kbps is the maximum data rate within market available UHF LSI to keep Japanese RR in 433MHz. To read 10000 tags (based on real container yard situation) it is need 5000 second with 200 second beacon interval. It can reduce to 800 second by using CSMA. It is need some real use dense models, power and duty limitation should be set for beacon only tags to achieve optimal reading time.
