3. Summary • Tuesday AM1; SRO • ~60 Attendees • 4 contributions were discussed Gifford, Freescale

4. Overview • WNG had 2 sessions at this meeting: • The first session had 4 presentations: • 802.21 Liaison (11-06-0374r0). This presentation initiated a discussion on the liaison received from 802.21. • A presentation of the OBAN concept: An IST Project under EC’s 6th framework (11-06-0353r0): This presentation introduces the concept of OBAN (Open Broadband Access Network), an European funded project under the IST 6th framework program. It focussed on the mobility architecture and the challenges and potential solutions for fast handovers. • Introduction to CIRCLE (Communications Infrastructure Restoration in the event of Catastrophic Loss of Equipment) (11-06-0433r0). This presentation initiated a discussion of catastrophic loss of communications infrastructure and highlighted the need for a standards approach to providing rapid recovery. • 802.11 MAC Extensions for Increasing Aggregate WLAN Throughput (11-06-0408r0). This presentation described a MAC protocol that allows parallel use of multiple channels which can boost WLAN aggregate throughput beyond what a link protocol can. Gifford, Freescale

5. Overview (cont) • The second session (held as part of mid-week plenary) had 3 presentations: • 802.11 and PLC (11-06-0474r0). This presentation IEEE 802.11 technologies are relevant to Power Line Communications (PLC). It introduced IEEE PLC standardization effort (P1901) and offered some ideas of where partnerships can be established • Update on HD Video over WLAN (11-06-0360r0). This presentation provided a summary of activities on HD video over WLAN. The discussion focused on trends, use-cases in HD video, and relevant MAC enhancements with respect to these cases. The scope of a possible amendment to 802.11 was also presented. • More “what is 802.11u?” (11-06-0375r0). This presentation provided a deeper understanding of the scope of 802.11u.

8. Jan06 Session WNG Objectives • January 2006, Big Island, Hawaii, USA • WNG had 2 main topics for discussion that session: • Video transmission update (11-06-0039r2). This paper gave a brief update to the video transmission presentation given in the previous November meeting. • CBP and David Allen’s methods (11-06-0056r0): This paper explained how can Dave Allen’s (reference in document 11-06-0056r0) ideas be applied to the running and organization of the study group (organization, brainstorming, quality). • March 2006 Goals • Ambient Project Update • OBAN (European IST Project) Gifford, Freescale

9. Mar06 Session WNG Objectives • Video Transmission • OBAN and Ambient Update • Prepare for IEEE Interim May 2006 Gifford, Freescale

10. 802.21 Liaison • IEEE 802.21 is developing standards to enable handover and interoperability between heterogeneous network types including both 802 and non 802 networks. • Michael G. Williams (IEEE 802.21) sent in the following contribution/liaison 802.11-06/0246r0 • Stephen McCann & Vivek Gupta sent in the following contribution for the WNG to consider for options available to 802.11 or 802.11-06/0374r0 • Session notes: • There are eight (8) shalls in the .21 liaison request, they need to review the impact; this is an 802.11 WG issue. • 802.11 architecture 802.1 SAP interfaces, enforce across all WGs; potentially new SAPs…this is an 802 issue. TGu is handling hand-off for 802.11, recommended practice. • Thank them, let an individual bring a contribution to 802.11. • 802 arch group; but they have no authority • Media independent handover func and arch? Inside 802.11 DSS has magnitude issue wrt speeds and handover. 802.11k maybe can handle, 16d, 16e, 15.4a, etc. • Action: Send a thank you reply and 802.11 should wait for the 802.21 ~Jul06 Plenary Tutorial.

11. OBAN Liaison • Thomas Haslestad (OBAN) sent in the following contribution/liaison 802.11-06/0353r0 • This presentation introduced the concept of OBAN (Open Broadband Access Network), a European funded project under the IST 6th framework program. • The presentation focused on the mobility architecture and the challenges and potential solutions for fast handovers. • Session notes: • Reuse “unused” Cable MODEM, et. al. and WLAN capacity in residential housing for public traffic i.e., offer service providers additional revenue streams for legacy or in market capacity. • Seamless mobile broadband coverage in urban areas • Action: No action, just an update.

12. CIRCLE Liaison • Rich Kennedy (CIRCLE “group”) sent in the following contribution/liaison 802.11-06/0433r1 • Communication Infrastructure Restoration in the event of Catastrophic Loss of Equipment (CIRCLE) • Session notes: • In 2004-2005 there were lots of worldwide disasters e.g., Tsunami, Earthquakes, Hurricanes, Typhoons, etc. • Having a quick i.e., 48 hours “push button solution” would be nice • Goal is to support emergency management • Vision: • Recommended practices, equipment and procedures would provide FEMA/DoHS with ready to deploy option • Action: No action, just an update. Gifford, Freescale

13. HT MAC extensions aka CCC MAC protocol • Mathilde Benvenistesent in the following contribution/liaison 802.11-06/0408r0 • Session notes: • Simple 802.11/.11a/b/g/n MAC Extensions for Increasing Aggregate i.e., BSS, Mesh, etc. WLAN Throughput • Described a MAC protocol that extends the distributed MAC protocol for IEEE 802.11 wireless LANs to achieve high aggregate throughput, in excess of what can be attained by the current TGn proposal. • This is accomplished by enabling the use of multiple channels by a set of wirelessly connected nodes (e.g., a BSS or a wireless mesh network), and simultaneous communication on multiple channels by a single device. The Common Control Channel (CCC) MAC protocol can be used in conjunction with proposed IEEE 802.11n (High Throughput) enhancements, and as part of the mesh medium access coordination protocol in the planned IEEE 802.11s (Mesh Networking) standard. • Action: No action, just an update.

We discuss trends, use-cases in HD video, and relevant MAC enhancements with respect to these cases. We discuss the scope of a possible amendment to 802.11. Gifford, Freescale

15. 802.11u? • Mike Moreton sent in the following contribution/liaison 802.11-06/0375r0 • Not discussed on Tue 7Mar06 • Abstract: This document gives a longer personal overview of the aims of TGu and is an extension of an earlier presentation in WNG. As we’re still at the “call for proposals” stage, we can’t be explicit about how these aims will be achieved. Gifford, Freescale

16. 802.11 and BPL • David Hunter sent in the following contribution/liaison 802.11-06/0474r0 • Not discussed on Tue 7Mar06 • Abstract: IEEE 802.11 technologies are relevant to Power Line Communications (PLC). Similarities of their respective environments have led to similar technologies. Making these solutions as close as possible to each other will benefit both. This presentation is an individual’s proposal not for a P802.11 project, but for close cooperation between P802.11 and the IEEE PLC standardization effort (P1901). Gifford, Freescale
