First is the mismatching between the scope section and the purpose section. The second is to discuss whether 10 Mbps is enough for the BAN applications. Purpose:Request the BAN group to increase the maximal data rate to meet the requirements of BAN applications. Notice:This document has been prepared to assist the IEEE P802.15.

In 5.4 Purpose of Proposed Standard –Data rates, typically up to 10Mbps, can be offered to satisfy an evolutionary set of entertainment and healthcare services. Does 10Mbps is enough for BAN applications?

Handheld devices now already support HD video –Cannon HV20 HD camcorder –Sony GV-HD700E HD Video Walkman –etc Video glasses support high resolution now –I-O Display i-glasses VIDEO - Head mounted display - 800 x 600 –etc.

5. doc.: IEEE 802.15-07/0xxxr0 Submission November 2007 Huai-Rong Shao et al., SamsungSlide 5 MPEG4/H.264 AVC Stream Useful standard for portable devices and internet video applications Data rate usually from 64Kbps to 15Mbps, but can be up to 240Mbps for HD video

7. doc.: IEEE 802.15-07/0xxxr0 Submission November 2007 Huai-Rong Shao et al., SamsungSlide 7 Medical Image/video Applications Lossless compression may be needed to keep image quality –Image resolution even bigger than HD video for CE devices –Usually compression ratio is about 3:1 to 10:1 10 Mbps may not be enough to support medical image/video sensor allications

8. doc.: IEEE 802.15-07/0xxxr0 Submission November 2007 Huai-Rong Shao et al., SamsungSlide 8 Conclusion 10 Mbps is not enough to support many BAN applications Recommendation –The group specify higher data rate than 10Mbps to meet the requirements of BAN applications
