Session #9 of the IEEE 802.16 Working Group on Broadband Wireless Access took place on 11-15 September 2000 in Denver, Colorado, USA. The meeting was notable for major progress in all Task Groups and for a Working Group decision to use a single MAC across all projects.
Task Group 1 (TG1): Air Interface for 10-66 GHz
TG1 resolved the 315 comments received in response to the Final Task Group Review of its working version (802.16.1-00/01) of the IEEE 802.16.1 air interface (10-66 GHz). The MAC team also:
Task Group 2 (TG2): Coexistence
In meetings chaired by new Co-Chair Andy McGregor, TG3 reviewed its Recommended Practice on Coexistence of Broadband Wireless Access Systems. The Group produced a Summary (including 11 Recommendations) and presented it in a meeting with the TG1 PHY team. The consensus was that a Final Task Group Review of the document is now in order, in preparation for a Working Group Letter Ballot beginning at Session #10. The review will be based on Revision 9 of the working document. Liaison letters were produced to inform several organizations of the review. An Interim Meeting, with Andy McGregor as host, was scheduled for 25-25 October in Ottawa, Canada to process comments received to that point.
Task Group 3 (TG3): Air Interface for licensed bands, 2-11 GHz
TG3 made the major decision to request a common medium access control (MAC) layer across the Working Group. This action, following a Thursday night session in which TG1 MAC Chair Carl Eklund addressed TG3 concerns in a detailed presentation, allows TG3 to focus on refinements to TG1's advanced MAC rather than on development of a new one.
The decision also frees TG3 to focus intently on physical layer (PHY) development. TG3 issued a Call for Contributions for initial PHY proposals, due by 30 October for consideration at Session #10. Only submissions to Session #10 will be eligible for invitation to submit a more detailed proposal to Session #11. The Call for Contributions includes a newly-developed list of PHY Evaluation Criteria, based partially on 13 contributions received and to be further refined at Session #10. A second Call for Contributions was issued on traffic and deployment models and well as channel models.
TG3 also reached a milestone by completing and adopting its Functional Requirements Document 802.16.3-00/02 after resolving a final round of 74 comments.
WirelessHUMANTM Study Group (Wireless High-Speed Unlicensed Metropolitan Area Networks)
The (WirelessHUMANTM) Study Group completed an IEEE Project Authorization Request (PAR) requesting approval to initiate a standardization effort. The PAR was approved by 802.16 and sent to IEEE 802.11 and 802.15 for their comments. It will be submitted (possibly following modifications) to IEEE 802 for approval in November.
The PAR indicates rapid development process and a correspondingly focussed project. Namely, the PAR would derive a standard (aimed at the 5-6 GHz bands but applicable from 2-11 GHz) by developing modifications to the 802.16 MAC and to the 802.11a OFDM PHY (and/or the similar HIPERLAN/2 PHY). The plan is to complete a tentative draft by May 2001.
Working Group Progress
Aside from the activities of its Task Groups, IEEE 802.16 as a whole progressed in many ways at Session #9. Here are some highlights:
The Working Group approved a liaison letter to ETSI BRAN; this letter thanked ETSI BRAN for its recent arrangement offering access to private documents and indicated an intent to reciprocate. The Working Group also approved letters to several other organizations.
Attendance at Session #9 was 144; see the attendance list. 126 people attended during enough meeting intervals to receive credit for having "participated" in the session for membership purposes; this was just shy of the record 128 set at Session #8.
Session #9 was held in conjunction with the 2000 IEEE Radio and Wireless Conference (RAWCON2000). 802.16 attendees were invited to attend the RAWCON Keynote Address, the evening receptions and panel sessions, and a lunch. The two events worked well in tandem.
Session #10 will be held in Tampa, Florida, USA on 6-10 November in conjunction with the IEEE 802 Plenary Meeting. The Session will open at 1 pm Monday and close by 5 pm Thursday. Monday morning is available for Task Group meetings. Friday morning will be used to process documents and prepare materials for Working Group Letter Ballots.
Session #11 was planned for Tel Aviv, Israel on 22-26 January 2001, with Naftali Chayat of BreezeCOM as host.
The Session #9 document list indexes the documents processed during the week of the meeting as well as followup documents.
About IEEE 802.16
The IEEE 802.16 Working Group on Broadband Wireless Access Standards is creating the WirelessMANTM family of standards for wireless metropolitan area networks. The mission of Working Group 802.16 is "to develop standards and recommended practices to support the development and deployment of fixed broadband wireless access systems." 802.16 is a unit of the 802 LAN/MAN Standards Committee, the premier transnational forum for wired and wireless networking standardization.
