Moved: Second: Vote: Discussion Points: (*) Unresolvable conflict on Monday 1100 Hrs (*) 90 minutes or even 2 hour teleconferences as opposed to 1 hour – setting the stage for a topic takes a while that 1 hour is not sufficient in many instances. We could end the teleconference sooner, if there is no reason to continue (*) Convenient time slots – rotate between US-friendly, Europe-friendly and Asia-friendly Slide 17 Ganesh Venkatesan, Intel Corporation Page 17 Alex Ashley, NDS Ltd Peter Ecclesine, Cisco Systems

18 What is OBSS? OBSS Definitions: Scope of OBSS Solution –
September 2008 November 2007 doc.: IEEE /2752r1 doc.: IEEE /1003r0 What is OBSS? March 2009 OBSS Definitions: OBSS edge -- Any two APs operating in the same channel and can hear each other (either directly or via a STA associated to one of the APs) OBSS Graph – is a graph where APs are nodes of the graph and the edges are OBSS edges and every AP with in the OBSS graph can be connected via one or more OBSS APs to every other AP in the OBSS graph Length(OBSS graph) – longest shortest path between any two APs in the OBSS graph Size(OBSS graph) – number of nodes (APs) in the OBSS graph Scope of OBSS Solution – if length(OBSS graph) <= 2 and the size(OBSS graph) <=3 , enable the OBSS QAP solution otherwise (a) backoff to legacy (non .11aa) mode or (b) use a different solution Slide 18 Ganesh Venkatesan, Intel Corporation Page 18 Alex Ashley, NDS Ltd Peter Ecclesine, Cisco Systems
