3. doc.: IEEE 802.11-03/533r0 Submission July 2003 Clint Chaplin, Symbol TechnologiesSlide 3 Problem Statement Develop a standard to allow fast roaming in a general way that will allow seamless connectivity during a roam that can be extended for future negotiation requirements

4. doc.: IEEE 802.11-03/533r0 Submission July 2003 Clint Chaplin, Symbol TechnologiesSlide 4 Possible Solutions 1 Make before break (associate with new AP before dropping association from old AP) Pre-association negotiation (allow handshaking and negotiation before Associate Request/Associate Response) Problem: APs will probably be on different channels

6. doc.: IEEE 802.11-03/533r0 Submission July 2003 Clint Chaplin, Symbol TechnologiesSlide 6 Possible Overlaps 1 IEEE P802 Handoff Study Group intends to develop a roaming solution at the 802 level, more specifically for multi-interfaces devices needing to handoff between interfaces where no procedures for handing off exist, and for handoff within a technology type (say 802.11) but between networks and administrative domains where handoff is not supported within the base standards (e.g. inter-ESS handoff in 802.11). The IEEE P802 Handoff Study Group does not address the more specific issue of fast roaming within an ESS, which this project will address.
