Content BRAN#27 topics Meeting results Author’s view on the status February 2002 doc.: IEEE 802.11-02/133r0 February 2002 Content BRAN#27 topics Meeting results Harmonised Standard DFS Framework Proposal Author’s view on the status Implications to TGh work Agenda items for the St.Louis meeting Mika Kasslin, Nokia Mika Kasslin, Nokia

February 2002 doc.: IEEE 802.11-02/133r0 February 2002 TGh related groups The Harmonised Standard (HS) group had four meetings Agenda in BRAN27d033r1 Closing report BRAN27d066 The HiperLAN (HL) Spectrum Group had five meetings Agenda in BRAN27d043 Tentative meeting report in BRAN27d097 Mika Kasslin, Nokia Mika Kasslin, Nokia

The topics of BRAN#27 1) Harmonised Standard 2) DFS Framework Proposal February 2002 doc.: IEEE 802.11-02/133r0 February 2002 The topics of BRAN#27 1) Harmonised Standard Review of the draft HS v0_h ”Maximum of minimum” power requirement (TPC) 2) DFS Framework Proposal IEEE 802 proposal as a liaison RLAN DFS framework proposal drafting Mika Kasslin, Nokia Mika Kasslin, Nokia

February 2002 doc.: IEEE 802.11-02/133r0 February 2002 1) Harmonised Standard The only topic was the one discussed also in the Dallas 802.11 meeting TPC related ”Minimum output power” requirement Both the phrase and the definition in v0_h misleading and will be rephrased A proposal in revised draft v0_i, BRAN27d074 No changes to the requirement itself 6 dB still working assumption Timeline of the HS approval approved Annex in the closing report (BRAN27d066) Mika Kasslin, Nokia Mika Kasslin, Nokia

2) DFS Framework The main topic in the Spectrum Group February 2002 doc.: IEEE 802.11-02/133r0 February 2002 2) DFS Framework The main topic in the Spectrum Group The IEEE 802 proposal was presented and discussed extensively The more advanced DFS method proposed was well-received Ran out of time in preparing a proposal of our own No real conclusions, a very draft working document (BRAN27d072, Draft LS to JPT5G v3) The drafting group will continue creating a RLAN proposal to JPT5G for their meeting in March 25-27 Teleconferences every Tuesday Mika Kasslin, Nokia Mika Kasslin, Nokia

2) DFS Framework Author’s view on the status: February 2002 doc.: IEEE 802.11-02/133r0 February 2002 2) DFS Framework Author’s view on the status: RLAN community has a common goal Requirements in the JPT5G proposal far too tight The framework has to provide flexibility in implementation The RLAN framework proposal will have just basic requirements, and few examples of mechanisms which can be used in DFS implementation silent periods for radar measurements radar detection during normal operation etc. should also have some simulation results on radar detection performance Mika Kasslin, Nokia Mika Kasslin, Nokia

2) DFS Framework Reminder February 2002 doc.: IEEE 802.11-02/133r0 February 2002 2) DFS Framework Reminder The proposal will be sent to JPT5G, which is preparing European views on the agenda item 1.5 of WRC-2003 Possibly and hopefully helps in getting global spectrum allocation for 5 GHz RLANs Separate from the HS work done in BRAN HS will go through a 60-day vote in which national standards organizations are voting JPT5G ”not interested” on the HS Mika Kasslin, Nokia Mika Kasslin, Nokia

Implications to TGh? How to proceed? February 2002 doc.: IEEE 802.11-02/133r0 Implications to TGh? How to proceed? February 2002 Since DFS Framework is beyond the scope of our task, which is to develop a DFS mechanism that provides for radar detection Basic requirements are clear enough Methods to silence and vacate channel Methods to measure and assess channel conditions TGh should not standardize DFS algorithm TGh should Continue with its task, which is to standardize DFS and TPC mechanisms and capabilities, bearing all the time in mind flexibility needed for possible changes in requirement details ”good engineering” Mika Kasslin, Nokia Mika Kasslin, Nokia

St.Louis agenda items Joint meeting with R-Reg (1.5 h) February 2002 doc.: IEEE 802.11-02/133r0 February 2002 St.Louis agenda items Joint meeting with R-Reg (1.5 h) Matters arising from the DFS framework TPC review (3.5 h) Confirm results of the Dallas meeting Possible new contributions DFS review (20 h) Frame descriptions DFS procedure description => New draft to WG LB Mika Kasslin, Nokia Mika Kasslin, Nokia
