Objective Highlight and resolve inconsistencies between Comparison Criteria (11-03-0814r25) and baseline documents (PAR and 5 criteria) H.Bonneville, B.Jechoux, Mitsubishi ITE

Nature of inconsistencies CC vs CC CCs vs PAR CCs vs 5Criteria H.Bonneville, B.Jechoux, Mitsubishi ITE

CC vs CC Environments applicable for system simulations Month 2003 doc.: IEEE 802.11-03/xxxr0 CC vs CC Environments applicable for system simulations  Market Requirements: QoS support and aggregate throughput are key metrics for Hot Spots and can not be ignored. H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE

CCs vs PAR (1/2) TGn PAR clearly prioritised 3 environments: Month 2003 doc.: IEEE 802.11-03/xxxr0 CCs vs PAR (1/2) TGn PAR clearly prioritised 3 environments: “Initial usage models envisioned include hot-spot, enterprise and residential; others may be included” System performance comparison does not include key metrics (CCs 19 & 20) for Scenario 6 (hot-spot).  Performance evaluation for scenario 6 does not satisfy the PAR.

CCs vs PAR (2/2) TGn PAR targets new market segment : Month 2003 doc.: IEEE 802.11-03/xxxr0 CCs vs PAR (2/2) TGn PAR targets new market segment : “The purpose of the project is to improve the 802.11 wireless local area network (LAN) user experience by providing significantly higher throughput for current applications and to enable new applications and market segments.” CC19 (QoS applications support) is optional, while most of foreseen new market segments will require QoS support.  Optional CC 19 does not satisfy the PAR.

Month 2003 doc.: IEEE 802.11-03/xxxr0 CC vs 5 Criteria TGn 5Criteria clearly states that the standard amendment shall address A/V applications “New usages such as simultaneous transmission of multiple HDTV signals, audio, and on-line gaming, will drive the need for higher throughput in the home” CC19 (QoS applications support) is optional for ALL Scenarios – Residential, Enterprise and Hot Spot.  Expectations of the 5 Criteria are not met if CCs do not require A/V traffic support.

A Quick and Clean fix 1) Include Scenario 6 in CCs 19 and 20 Month 2003 doc.: IEEE 802.11-03/xxxr0 A Quick and Clean fix 1) Include Scenario 6 in CCs 19 and 20 2) Make CC19 mandatory  Cost is negligible Requires no extra simulation (same as for CC18 and CC24) Some additional effort to compile results H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE

Motion Include Scenario 6 in CCs 19 and 20 and make CC19 mandatory. Mover: Bruno Jechoux Second: H.Bonneville, B.Jechoux, Mitsubishi ITE
