  4. Existing Standards related to LPWA

  5. Suitability of Existing IEEE Standards • IEEE802.15.4g FSK(Wi SUN PHY) • 50Kbps • CC1200 : -109dBm • IEEE802.15.4k FSK • In progress

  6. High value-added use cases of LPWA • Large-scale populated services with reliable and secure services • Public Services: Critical facility monitoring, Public Infrastructure monitoring, Children Guardians • Industrial Services: Process monitoring, Smart Building • Mission oriented services • Surveillance/Monitoring: Intrusion/Burglary Surveillance, Hazardous materials monitoring • Living Services: Asset tracking, Social Safety Nets, eHealth/eWelfare • Ground surface level antenna height wireless communication

  7. Active Interfering Users per Timeframe • The number of active users in a given network cell • Interfering users may also originate from different uses-cases (e.g. for application area smart city) Source : 15-16-0771-00-lpwa-use-cases-and-technical-requirements-for-lpwa-networks

  8. Suitability of Candidate Technologies • Reliability for high value added services • Priority based channel access for heterogeneous traffic • Optimal access control for various requirements • Dynamic resource allocation for mission oriented services • Flexible PHY control for service dependent channel access • Priority based random access • Extended Access Barring • Dynamic channel access control • Dynamic resource allocation • Contention free access • Unoccupied channel reuse • Channel hopping

  9. Work in progress for IG LPWA Report • Suitability testing and analysis are in progress. • Existing IEEE 802.15.4 FSK based standards(IEEE 802.15.4g / IEEE 802.15.4k) • Candidate Technologies • Future Meeting Schedule • March 2017 Plenary (Vancouver) • Fixed evaluation criteria • Presentation of contributions with focus technology options for LPWA • May 2017 Interim (Daejeon) • Presentation of contributions with focus technology options for LPWA • July 2017 Plenary (Berlin) • Final discussion on IG report
