  3. Need to standardize active LED-ID system for low-cost implementations • Need to apply to indoor LBS applications doc.: IEEE 15-12-0635-00-0led Goals Yeong Min Jang, Kookmin University

  4. Active LED-ID system definitions • LED-ID • Active LED-ID • Active LED-ID tag • Need to modify existing IEEE802.15.7 MAC protocol • Need to modify existing IEEE802.15.7 MAC services • Need to existing IEEE802.15.7 PHY layer doc.: IEEE 15-12-0635-00-0led Revision directions for active LED-ID standardization Yeong Min Jang, Kookmin University

  5. Need to modify processes: • Channel scanning • Channel access • Association/Disassociation • Synchronization • Need to modify MAC command frames • Need to insert location information field into MAC frames doc.: IEEE 15-12-0635-00-0led MAC protocol modification Yeong Min Jang, Kookmin University

  6. IEEE 802.15.7 standard:CSMA/CA protocol • For simple implementation of LED-ID networks: time-slotted ALOHA protocol doc.: IEEE 15-12-0635-00-0led Channel Access Method Yeong Min Jang, Kookmin University

  7. doc.: IEEE 15-12-0635-00-0led MAC frame modification • IEEE 802.15.7 MAC frame format • Proposed frame type • Proposed active LED-ID MAC frame format Yeong Min Jang, Kookmin University

  8. Need to modify MAC management service • Modify the primitives of MLME-SAP (Medium-access-control Link-Management Entity – Service Access Point) interface. • Need to modify MAC data service • Insert location information services. doc.: IEEE 15-12-0635-00-0led MAC services modification Yeong Min Jang, Kookmin University

  9. Current IEEE 802.15.7 standard specifies 3 PHY types: • PHY I: intended for outdoor usage with low data rate applications. • PHY II: intended for indoor usage with moderate data rate applications. • PHY III: intended for moderate data rate applications using CSK that have multiple light sources and detectors. • Need to define(or revise) particular PHY type for LED-ID reader and tag applications. • Need to define(or revise) particular PHY type for indoor LBS applications. doc.: IEEE 15-12-0635-00-0led PHY modification Yeong Min Jang, Kookmin University
