May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Abstract This presentation summarizes the changes specified in 08/0441 r 0 normative text changes for location in D 2. 0. Goal was to keep all features but simplify how they are defined and used so that all could be implemented easily Submission 2 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Location Request/Response • Replaced Location Request/Response frames with more succinct and meaningful separate frames for specific purposes • Aligned location data exchange with 11 k measurement request/response • Service options (i. e. timed location updates) better fit with measurement request/response • Reuse 11 k LCI for Geodetic – So removed capability from 11 v • Added Location Civic Request/Report – Removed various sub-options that were comment fodder • Instead of multiple encodings now just have a single encoding method implicit in request/report • Removed [highest, ap, building] resolution field as many found it confusing and had negligible value • Added Location Identifier Request/Report Submission 3 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Location Configuration Request/Response • Only used to configure STA to transmit new Location Track Notification frame so that other STAs can track location • Simplified options in config to provide this function • Removed any exchange of location data as that was editorial problem anyway Submission 4 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Location Track Notification • Public action frame • Replaces Location “Request” frames that were transmitted periodically • Defined as a public action frame (as it should have been anyway) • Includes simplified set of information – Radio – Motion – Time Submission 5 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Time Measurement • Two separated features • 1) Time Of Departure • 2) Time Synchronization Submission 6 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Time Of Departure • Optional feature used in combination with Location Track Notification • Updates to Clause 10, 12, 15…etc to match • New procedures in Clause 11 • New MIB object for enabling feature Submission 7 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Time Measurement • Pulled time measurement out to a separate Timing Measurement public action frame • Updates to Clause 10 to match • New procedures in Clause 11 • Added Time Measurement bit to Extended Capabilities IE • New MIB object for time measurement Submission 8 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 General Clause 10 • Completely updated for all changes Submission 9 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 Clause 11: Location Procedures • Added separate Clause 11 for location data exchange for civic and identifier frames under 11 k sections – Followed 11 k LCI Clause 11 style and content • Other location behavior simplified to specify configuration behavior and track notification Submission 10 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 PICS • Updated to include new separated functions • Clarify optional features for – Motion – TOD – Time Measurement Submission 11 Allan Thomson, Cisco Systems

May 2008 doc. : IEEE 802. 11 -07/0497 r 0 MIB • Added new RRM MIB objects – Civic – Identifier • Added new Mgmt. Options for – Time sync – TOD – Motion Submission 12 Allan Thomson, Cisco Systems
