  5. Monday am – ad hoc Bruce Kraemer, Intersil

  6. 5GHz Study Group • Original Intent • Standard Harmonization - Single Global Standard for 5GHz WLANs • International effort • IEEE, ETSI, MMAC • Interim Objective • Interworking mechanism • Interworking Proposal Concepts • Legacy backward compatibility maintained • Approaches so far based upon superframes using either DCF or PCF • HCF now being investigated • Likely to have no impact on Client, AP implementation only • Future plan • 5GHz Partnership Project now called 5WING Bruce Kraemer, Intersil

  7. IEEE Hilton Head Accomplishments March 12-16,2001 Motions: PProposed that we extend the 5GSG to the next joint plenary. Motion passed in study group 36/0/0 Motion passed in plenary 74/6/4 PProposed that we pursue the creation of a 5GHzPP as a vehicle for establishing a single global standard. Motion passed in study group 23/0/1 PPAR document (11-01-172) passed in plenary 41/8/17 P5 Criteria document (11-01-173) passed in plenary 42/6/13 Bruce Kraemer, Intersil

  8. 9. Scope of Proposed Project: Establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. Extension of each of the MAC and PHY layers of these standards will be defined collaboratively to achieve coexistence and inter-working. 10. Purpose of Proposed Project: To establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. A subsequent project under a separate PAR is to create a single converged standard in the 5GHz band. Bruce Kraemer, Intersil

  9. BRAN #24 European Telecommunications Standards Institute BRAN#24 26 June to 29 June 2001 Sophia-Antipolis, France Executive Summary - BRAN24d141 1.      Defer decision to continue/discontinue the Inter-working project until after the IEEE meeting in Portland. It was noted that both BRAN and IEEE will be meeting during the same week in September in Seattle and a joint meeting at that time would be desirable and presumably easy to arrange. Bruce Kraemer, Intersil

  10. Tentative Schedule for 5WING SG • Operational Procedures • IEEE802.11 May: Prepare material (e.g. relationship diagram) and kick-off discussion • BRAN#24/IEEE802.11 July: initial submissions • IEEE802.11 Sep/BRAN#25: first draft prepared for circulation • Project Requirements Definition • IEEE802.11 Nov/BRAN#26: initial submissions • IEEE802.11 Jan 2002/BRAN#27: first draft prepared for circulation • Terms of Reference Bruce Kraemer, Intersil

  11. BRAN 24d141 – How as the WLAN Market evolved? 1.      A general discussion ensued as to what has happened in the WLAN market over the last quarter that may influence the answer to Jamshid’s question: a.       Wi-Fi (.11b) is selling faster than anyone expected particularly in the US but also in the rest of the world b.      Due to the high penetration if Wi-Fi it will be difficult to omit backward compatibility with .11b when new products are introduced c.       The market progression has been from the enterprise to SOHO and most recently Hot Spots such as airports, hotels, coffee shops, … d.      The market drivers have been:                                             i.      Enterprise – usable data rates, ease of installation (no wires!), mobility                                            ii.      Home – spreading of broadband access, ease of installation, low cost                                           iii.      Hot Spots – ease of installation, low cost, profit potential, emergence of WISP aggregators such as GRIC e.  The consensus expressed at the WECA meeting in Helsinki on 6-13,14 seemed to be that because of the perceived backward compatibility requirement new 5GHz products will likely be dual band (2.4 and 5 GHz) after the initial wave of 5GHz only products f. The multi-band solution scenario will impact .11b/.11a, H2/.11b, TGg, H2/.11a product definitions g. Andy Gowen noted that 2.4 GHz WLAN products are not legally used in public spaces UK. h.  Telecom operators will resist the development of networked WLAN Hot Spot which begin to look like WANs Bruce Kraemer, Intersil

  12. BRAN 24d141 – How did Interworking evolve?   “Why did IEEE authorize a task group, TGj, dedicated to developing an IW recommended practice given the apparent lack of interest?” Garth reviewed the history of how 5GSG bifurcated into TGj and 5WING with the bottom line being that in order to retain interest in the 5GS it was felt that a short term interim project needed to be identified and, IW was a good candidate because much of the work to define an IW standard could be reused in the 5GS project. Neither H2 nor .11a will likely be the final WLAN standard and probably the most important work activity going forward is to set up a framework to develop global standards and then apply that framework to developing the 5GSG.

  23. History of 5GSG FormationTampa, Nov 6-10, 2000 802.11 Task Group reports • 5GHz Globalization Study Group – The Study Group was formed after the contingencies of forming similar study groups at ETSI and MMAC were fulfilled. • Bruce Kraemer was appointed Vice Chair • Garth Hillman was appointed Secretary – The 802.11 working group directed this SG to produce comments on the 802.15 low speed PAR, and the 802.16 WirelessHUMAN PAR. – The study group drafted a proposal to IEEE 802 to come up with coexistence and spectrum sharing guidelines that will be reviewed before new PARs can be granted in the 5GHz band.

  24. History of 5GSG FormationLa Jolla, July 10-14, 2000 IEEE P802.11 Wireless LANs To: Mr Jamshid Khun-Jush, Chairman, ETSI Project BRAN Date: July 13, 2000 Subject: re: IEEE P802.11 request to ETSI for considering the adoption of the IEEE P802.11a 5 GHz Wireless LAN standard as a member of HIPERLAN family of standards Dear ETSI BRAN Officers and Members, Thank you for your advice that considerations regarding several areas are needed for EP BRAN to be able to make an assessment on the further handling of the IEEE P802.11 request that the IEEE P802.11a 5 GHz Wireless LAN standard be adopted as a member of HIPERLAN family of standards. These areas include regulatory, application and technical aspects. Unfortunately the arrival of the liaison letter right at the end of the May meeting precluded its consideration until the July Plenary, and consequently we missed the opportunity to arrange attendance at the June BRAN meeting by an 802.11 delegation. We would be pleased to attend at the next available meeting, which we understand is in Stresa during October 3-6, 2000, to pursue a path to resolving the matters raised in your letter. We extend an invitation to BRAN members to attend any future IEEE 802.11 meetings, details of which are available on the IEEE 802 website (http://www.ieee802.org/11/). The next meeting will be in Scottsdale, Arizona, September 18-22, 2000. We also suggest that we explore the possibility of a joint ETSI BRAN/IEEE 802.11 meeting in the coming year. The IEEE 802.11 WG is working to address the key points raised in your liaison letter. In particular, the matters of TPC and DFS are being studied in TGe (MAC Enhancement) and an Ad Hoc Group has been established to consider the harmonisation of existing standards towards adoption of a single global standard. It is anticipated that the Ad Hoc Group will identify overlapping services and applications as well as look at issues of coexistence of the different standards. We anticipate that representations from the Ad Hoc Group will be made during the BRAN#20 meeting in Stresa. On the matter of IPR, IEEE P802.11 has obtained letters of assurance that owners of all IPR known to us will provide on request licenses without discrimination and for a reasonable fee. These letters ensure that all known IPRs were addressed in sufficient time to avoid the IEEE 802.11 family of standards being blocked at a later stage by the refusal of these IPR owners to grant licenses. As per your request, a full set of documentation, including standards IEEE 802.11 (1999), IEEE 802.11a and the set of IPR letters are provided as attachments to this liaison. Sincerely, Stuart Kerry, Chairman IEEE P802.11 Source: Doc 11-00-241 Bruce Kraemer, Intersil
