April 2007 doc.: IEEE 802.11-07/0570r0 August 2008 Abstract Proposed modifications to VHT60 PAR based on Executive Committee discussions Eldad Perahia, Intel Corporation Eldad Perahia, Intel Corporation

EC Discussion following Denver EC meeting August 2008 EC Discussion following Denver EC meeting http://grouper.ieee.org/groups/802/secmail/msg11073.html Bruce Kraemer, Bob Heile, Paul Nikolich and Steve Shellhammer held a conference call on July 24 to discuss a path forward for the 802.11 VHT60 PAR Proposed modifications to VHT60 PAR A stronger declaration of coexistence with 802.15.3c in the Scope of the PAR. Possible wording that could be used is the wording used in the motion to amend during the closing EC meeting, Replace the text "Addresses coexistence with other wireless systems" with the text "Ensure coexistence with IEEE 802.15.3c.“ Adding a definition of coexistence in the Additional Notes section. One possible definition is the definition in 802.15.2, which was approved by both the 802.11 and 802.15 working groups. Adding 802.15.3c and ECMA TC48 to section 7.1 (Projects will similar scope) of the PAR Eldad Perahia, Intel Corporation

Subsequent EC discussion on “ensure coexistence” August 2008 Subsequent EC discussion on “ensure coexistence” http://grouper.ieee.org/groups/802/secmail/msg11085.html “It has been brought up by several people that the term "ensure" is almost a synonym for "guarantee" which was not the intention.” New VHT60 scope wording proposal by Steve Shellhammer Supports mechanisms to enable coexistence with IEEE 802.15.3c Eldad Perahia, Intel Corporation

New Proposed Changes to PAR (1/2) August 2008 New Proposed Changes to PAR (1/2) 5.2 Scope of Proposed Standard: The scope of this project is to define an amendment that shall define standardized modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC) to enable operation in the 60 GHz frequency band (typically 57-66 GHz) capable of very high throughput. The MAC and PHY specified in this amendment: Enables a maximum throughput of at least 1 Gbps, as measured at the MAC data service access point (SAP) Enables fast session transfer between PHYs Maintains the 802.11 user experience Supports mechanisms to enable coexistence with IEEE 802.15.3c Addresses coexistence and with other systems in the band Eldad Perahia, Intel Corporation

New Proposed Changes to PAR (2/2) August 2008 New Proposed Changes to PAR (2/2) 7.1 Are there other standards or projects with a similar scope? No Yes Explanation: There are 60 GHz PHY projects in 802.15.3c and ECMA TC48 Sponsor Organization: IEEE 802 Project/Standard Number: IEEE 802.15.3c Project/Standard Date: 2008-07-01 Project/Standard Title: Part 15.3: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for High Rate Wireless Personal Area Networks (WPANs): Amendment 2: Millimeter-wave based Alternative Physical Layer Extension Sponsor Organization: ECMA Project/Standard Number: TC48 60 GHz Project/Standard Title: PHY and MAC layers for 60 GHz wireless network Eldad Perahia, Intel Corporation
