November 14, 2007 doc. : IEEE 802. 15 -924 Outline • Attributes of the mm. Wave WPAN Framework • Gaps and limitations of the current proposals Submission 5 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 mm. Wave 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 Submission 6 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 mm. Wave 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) Submission 7 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 mm. Wave 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 Submission 8 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 Where are the Gaps? Submission 9 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 What is Commonality Applications PAL’s Upper MAC Lower MAC FEC Modulations Radio Submission FEC Bar as high as possible Modulations Radio 10 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 Submission 11 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 Submission 12 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 Mandatory High-rate to Cover Diverse Usage Models for DEV&PNC? Low rate common mode Does not meet Technical Requirements rate of 2 Gbps Submission 13 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 Submission 14 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 Lack of Efficient Operation in Dense Environment • A piconet should be able to support links with very high throughput and complex Qo. S 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 Submission 15 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 Submission 16 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 Submission 17 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 World Wide Authentications not known • It is not clear how the Authentication is done in the proposals Submission 18 Ali Sadri, ed. al. Intel corporation, et. at.

November 14, 2007 doc. : IEEE 802. 15 -924 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 downselection or confirmation until issues are resolved Submission 19 Ali Sadri, ed. al.
