This report provides insights into the IEEE 802.16 Working Group's activities focused on developing interoperable air interface standards for Fixed Broadband Wireless Access (FBWA) systems. The base standard, published earlier this year, addresses the MAC and PHY layers for fixed point-to-multipoint BWA systems operating in 10-66 GHz licensed bands, as well as focused efforts on 2-11 GHz bands through merged task groups. Ongoing initiatives include co-existence practices and necessary amendments for unlicensed frequency bands. A call for contributions is pending to advance these standards.

  1. 802.16 Liaison Report Mika Kasslin 802.16 Liaison to 802.11 Mika Kasslin, Nokia

  2. IEEE 802.16: Overview • Working group developing interoperable air interface standards for Fixed Broadband Wireless Access Systems (FBWA) • Known also as WirelessMANTM group • The ”base” standard published early this year • MAC and PHY for fixed point-to-multipoint BWA systems • Tailored for 10-66 GHz licensed bands Mika Kasslin, Nokia

  3. IEEE 802.16: Activity • Four ongoing activities • TGa – PHY&MAC amendments • Two former task groups (TG3 and TG4) merged together • Addresses both licensed and unlicensed bands between 2-11 GHz • Original TG4 PAR for unlicensed bands excluded deliberately the 2.4 GHz ISM band • TG2 – Co-existence group • Recommended practice for coexistence of BWA systems • RP for 10-66 GHz published 2001 • Currently addressing 2-11 GHz (primarly licensed bands) • TGc – Profile task group for 10-66 GHz • Study Group on MBWA • Interim meeting next week 20-24 May in Calgary, Canada Mika Kasslin, Nokia

  4. IEEE 802.16a: Overview • Amendment to the ”base” 802.16 standard • Medium Access Control Modifications and Additional Physical Layer Specifications for 2-11 GHz • The latest draft D3 available since late March 2002 • The resulting standard specifies the air interface of fixed (stationary) broadband wireless access systems and applies to systems operating between 2 and 11 GHz, where such systems are permitted • Targeted unlicensed frequency bands include 5.25-5.35 GHz and 5.725-5.825 GHz Mika Kasslin, Nokia

  5. IEEE 802.16a: Activity • The plan: • May 02 interim: Revise the draft and start new WG letter ballot • July 02: Resolve comments and start Sponsor Ballot with the revised draft • How to implement that? • Pending call for contributions to fix the holes in the TGa draft D3.0 • Submission deadline today, May 17 • So far some contributions addressing co-existence in LE bands (e.g. MAC frame structure) Mika Kasslin, Nokia

  6. Friendly Reminder Download the revised TGa draft after the Calgary interim, review it, and feel free to provide comments Mika Kasslin, Nokia
