Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 Many of the papers pointed out that the existing MAC limits Throughput to ~ 50% of the AIR. Many of the papers pointed to the need to increase the AIR to 200 Mbps and add ‘fast’ mobility. Submission 4 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 The goal is to increase the AIR to >= 100 Mbps while retaining backward compatibility The goal is not to add WLAN/WWAN interoperability and En Route Mobility Submission 5 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 Standards Resource Conundrum The schedule for each of the IEEE 802. 11 task groups is as follows: IEEE 802. 11 e Estimated final approval January 2003 IEEE 802. 11 f Estimated final approval March 2003 IEEE 802. 11 g Estimated final approval January 2003 IEEE 802. 11 h Estimated final approval March 2003 IEEE 802. 11 i Estimated final approval September 2003 Sincerely, Stuart J. Kerry Chair, IEEE 802. 11 WLANs WG Submission 6 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 Standards Resource Conundrum Submission 7 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 The Points • We have a pretty good idea of what the requirements and scenarios are for the Wireless Next Generation • We have a pretty good idea of what the requirements and scenarios are for the OFDM Extension • We need the standards resource bandwidth to complete the work of the pending Task Groups and simultaneously open new Study Groups which will lead to Task Groups • The short term OFDM Extension will take 15 months best case • The long term Wireless Next Generation will take 3 -4 years Submission 8 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 Conclusion • It seems clear that the efficiency of our MAC needs improving • Therefore it seems that for the health of the industry long term there is a “root cause” to develop a Next Generation Global Standard • It is equally clear that we cannot complete the work of the existing Task Groups and then ‘do nothing’ for 3 -4 years while we develop the Next Generation Global Standard; that is we need an interim OFDM High Rate Extension • Some serious scheduling and out-of-the-box thinking needs to done by those in this room to optimize the use of our Standards resources to finish our existing work and launch HR extension and Next Generation Action Plans Submission 9 G. Hillman / AMD.

March 2002 doc. : IEEE 802. 11 -02/334 r 0 This Weeks Challenge • WNG to finish this week with an action plan to: 1. Develop an OFDM High Rate Supplement 2. Develop a WNG Standard • While not diluting the critical attendance at the existing TG sessions such that they are further delayed Submission 10 G. Hillman / AMD.
