Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs)

This document discusses options to determine project scope and content for Wireless NAN standards under IEEE P802.15, aiming to stimulate discussion and guide the development of a suitable PAR and 5C. Various options including amendments, new standards, and coordination strategies are analyzed. The submission aims to assist in quick progress and optimal framing of the PAR within the Study Group.

  3. Purpose and Goals • StimulateDiscussion • Assist SG to frame the PAR optimally • Make best use of work done by other 802.15 TGs • Assist WNAN activity to make quick progress Jay Ramasastry

  6. FUTURE WNAN STANDARD 802.15 PAR to address the relationship WNAN Standard 802.15.4 Standard PHY Specifications MAC Specifications TG4e MAC Amendment Based on WNAN Application Requirements Jay Ramasastry

  7. Range of Options • Amendment to 802.15.4 (802.15.4m) • New PHY (Options: NBFHSS, DSSS) • MAC enhancements related to PHY • Coordination with TG4e for other WNAN MAC requirements • Revisions to 802.15.4 (802.15.4n) • New PHY (Options: NBFHSS, DSSS) • Revisions to TG4e MAC being developed to add WNAN MAC requirements • New Standard under 802.15 (802.15.X) • New PHY (Options: NBFHSS, DSSS) • New MAC per WNAN requirements • New WG for NAN (Not a desirable option) • Obviously new everything Jay Ramasastry

  8. Pros/Cons of Options - 1 • Amendment to 802.15.4 (802.15.4m) • Most expedient (maybe) • Leverages existing 15.4 inertia and synergies (ZigBee, ISA100) • Adds new PHY and related MAC features • Most constrained approach • May not be technically ideal solution • May impose marketplace constraints Jay Ramasastry

  9. Pros/Cons of Options - 2 • Revisions to 802.15.4 (802.15.n) • May not be expedient • Leverages necessary aspects of the 802.15.4 and its MAC amendments • Adds a new PHY • May be less constrained approach • Not result in everyone’s technically ideal solution • May impose marketplace constraints Jay Ramasastry

  10. Pro/Con of Options - 3 • New standard in 802.15 (802.15.X) • More flexible technical approach (more options) • Could result in technically more ideal solution • No “backward compatibility” conflicts • Avoids bloating 802.15.4 • May take longer Jay Ramasastry

  11. Pro/Con of Options - 4 • New WG for NAN (802.yy) • Obviously new everything, most flexibility • Can’t leverage current work done under 802.15 groups • May take much longer • May be hard for chipmakers of 802.15 solutions to participate and integrate WNAN solutions • Up to EC to decide Jay Ramasastry

  12. Desirable Option • Write the PAR Scope and Requirements for a New 802.15.x Standard • Ask for creation of a TG to work on WNAN standard (TG 4f?) • This TG will develop the WNAN PHY options, and MAC/PHY interface requirements • This TG will coordinate with TG4e to develop a plan for the WNAN MAC • Coordination with and involvement of TG4e assures maximum leveraging of MAC work already accomplished • TG 4e and TG 4f may hold joint WNAN MAC meetings, or TG 4e may develop the WNAN MAC for TG4f • This approach will allow Tg4e to complete its current MAC amendment activity quickly and unhindered Jay Ramasastry
