5. Outline • Attributes of the mmWave WPAN Framework • Gaps and limitations of the current proposals Ali Sadri, ed. al. Intel corporation, et. at.

6. mmWave WPAN Framework • As many commonalities in the radio, MCS’s, Lower and Upper MAC, continuum • Simplicity • Minimal number of modes • Ease of implementation • Mandatory high rate to cover diverse usage models Ali Sadri, ed. al. Intel corporation, et. at.

7. mmWave WPAN Framework, (continue) • Coverage • LOS • NLOS • Efficient operation in dense environment • Reliable high rate transmission at various distances • Low latency for diverse usages • Isochronous • Asynchronous • Low power consumption per usage (average power & power efficiency) Ali Sadri, ed. al. Intel corporation, et. at.

8. mmWave WPAN Framework (continue) • Content protection for A/V and data traffic • Hooks in PHY and/or MAC for Lossless or visually/perceptually lossless compression, wired equivalent experience • Lossless compression for data • WW recognized • Authentication • Encryption • Multiple PAL’s on top of the same MAC and PHY Ali Sadri, ed. al. Intel corporation, et. at.

9. Where are the Gaps? Ali Sadri, ed. al. Intel corporation, et. at.

10. Applications PAL’s Upper MAC Lower MAC FEC Modulations Radio What is Commonality Applications PAL’s Upper MAC Lower MAC FEC Bar as high as possible Modulations Radio Ali Sadri, ed. al. Intel corporation, et. at.

11. Lack of Commonalities in the Radio, MCS’s, Lower and Upper MAC, Continuum Low rate common mode Lack of commonalities between the PHY and MAC Ali Sadri, ed. al. Intel corporation, et. at.

12. Lack of Simplicity • Many optional modes • Many redundant modulations choices • Many FEC choices • Many beamforming options • Difficult to choose a compatible mode • Difficult to implement all modes Ali Sadri, ed. al. Intel corporation, et. at.

13. Mandatory High-rate to Cover Diverse Usage Models for DEV&PNC? Low rate common mode Does not meet Technical Requirements rate of 2 Gbps Ali Sadri, ed. al. Intel corporation, et. at.

14. Coverage in LOS and NLOS • Channel models do not allow for evaluation of systems using beamforming • Beam forming techniques and capacity gains have not been described or quantified Ali Sadri, ed. al. Intel corporation, et. at.

15. Lack of Efficient Operation in Dense Environment • A piconet should be able to support links with very high throughput and complex QoS requirements • All devices within a piconet should be able to communicate with each other in high throughput • Spatial (spectrum) reuse and antenna training support is necessary Ali Sadri, ed. al. Intel corporation, et. at.

16. Low latency for diverse usages for Isochronous & Asynchronous? • Latency requirements are not clear (access, end-to-end, beamforming, etc) • May not meet the requirements of bursty data applications • Disk drives, server access, • Wireless equivalents of high-speed wired I/O buses • etc Ali Sadri, ed. al. Intel corporation, et. at.

17. Hooks in PHY and/or MAC for Lossless or visually/perceptually lossless compression, wired equivalent experience • There are no hooks defined in the MAC or PHY for A/V streaming and compression • for example, channel-state information (data rate, loss rate, …) feedback to encoder Ali Sadri, ed. al. Intel corporation, et. at.

18. World Wide Authentications not known • It is not clear how the Authentication is done in the proposals Ali Sadri, ed. al. Intel corporation, et. at.

19. Conclusion • Due to many gaps and issues with existing proposals and mergers • A specification without a 2+ Gb/s common mode would not meet approved requirements • Existing proposals cannot effectively be implemented • We recommend to hold off any further down-selection or confirmation until issues are resolved Ali Sadri, ed. al.
