2. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide2 Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [IG-BAN applications: use cases] Date Submitted: [November, 2006] Source: [Young Hyeog Jeon, Eunkyo Kim and Donghee Shim] Company: [LG Electronics] Contact: Young Hyeog Jeon Voice:[+82 2 526 4151], E-Mail:[yohaness@lge.com] Abstract: [Discussions on some applications related to body area networks (BAN)] Purpose: [To provide some application examples for BAN] Notice: Possible enhancements compared to 802.15.4 are summarized

3. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide3 Agenda Scenario 1 : In Music CD store Scenario 2 : At the Art Gallery Scenario 3 : On the bus stop Scenario 4 : In the car Benefit Direct use of 15.4 MAC into the that of BAN?

4. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide4 Scenario 1 : In Music CD store Browsing music samples Scenario Flow –When Young Hyeog enters a music CD store, he receives a BAN capable headset (or he is wearing his BAN capable headset already) –Finding several interesting new albums, he is feeling like trying selected sample tracks –Touching music albums, he can enjoy some sample tracks through BAN capable headset

5. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide5 Scenario 2 : At the Art Gallery Listening to the explanation of the art at the museum Scenario Flow –Entering Van Gogh Museum, Eunkyo receives a BAN capable headset (or she is wearing her own BAN headset already) –Under each picture frame, a BAN user interface, e.g. a button, is available –She can listen to the explanation of a piece of Van Gogh’s work by touching the button

6. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide6 Scenario 3 : On the bus stop Listen to the bus schedule information, e.g., bus number for certain destination, arrival time etc, at the bus stop Scenario Flow –Donghee has his own BAN device –He searches the destination information and his schedule (possibly any map data) in the web with BAN capable laptop and download into the BAN device –When he arrives a bus stop, he touch a button at the stop. –Then he can listen to the explanation of bus information for his destination

7. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide7 Scenario 4 : In the car In the car, BAN device can transmit user preferences data such as seat angle and handle position, then car system operates properly according to the downloaded data when a user sits. A person can configure his/her preferences using BAN capable laptop or mobile device etc and download data to the BAN device User preference configuration Car Management System

8. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide8 Benefit Ultra Low Power –Consume about 5% of Bluetooth power based on internal experimental results –User can enjoy the long-time battery life, e.g., for listening to the music (scenario 1) Easy to Use and Very Convenient –Don’t need to take something out or to write/input information since BAN interacts directly with human –Consequently, user interface, e.g. touch screen, is very user-friendly and convenient (scenario 2 and 3) Custom made information based on the preference of each individual can be extracted from the BAN –Recently user preferences become more emphasized –In consequence, BAN can interact with other outside networks to reflect each individual’s preference, (e.g. car operation initialization as described in scenario 4, user-oriented output as depicted in scenario 3)

9. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide9 Thoughts Analyzed benefits from several use cases are actually high-level requirements to be achieved in the BAN Re-use of currently available 15.x MAC in the that of BAN would be considered to meet the requirements in the BAN Initially, 15.4 MAC could be considered one of candidates for the use of that of BAN because of its low-power nature, however, some challenges should be resolved.

10. November, 2006Doc: IEEE 802.15-BAN-0457-01 Young Hyeog Jeon, et al Slide10 Direct use of 15.4 MAC in the BAN? IEEE802.15.4BAN Data rate Low (20~250kbps) High (up to 10Mbps in case of Music Streaming) QoS Scalability Low (Only up to 7 Guaranteed time slots) High (Medical scenario needs more guaranteed slots) QoS Differentiation NoneNeeded (Multiple scenarios need different level of QoS ) Security SimpleMore Needed (To pay with BAN device or to enter a room with human touch or to handle personal information etc. Safety NoneNeeded (Effect on human body should be considered)
