List of inconsistencies Inside CCs CCs vs PAR CCs vs 5Criteria H.Bonneville, B.Jechoux, Mitsubishi ITE

Inside CCs Environments applicable for system simulations Month 2003 doc.: IEEE 802.11-03/xxxr0 Inside CCs Environments applicable for system simulations Different sets of environments are considered for the system performance evaluation CCs. ==> Inconsistent since QoS support and aggregate goodput are key metrics for Hot Spots.

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” Scenario 6 (hot-spot) absent of key system performance criteria, CC 19 and 20. ==> Inconsistent since these CCs address only enterprise and residential scenarios and not hot-spots H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE

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 ==> Inconsistent since most of the foreseen new markets that 802.11n targets are expected to be QoS oriented H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE

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 ==> Inconsistent, CCs must consider consumer market. If kept optional, we will not be able to compare proposals regarding A/V traffic H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE

Quick (and clean) fix 2 steps: 1) Include scenario 6 in CC19 and CC20 Month 2003 doc.: IEEE 802.11-03/xxxr0 Quick (and clean) fix 2 steps: 1) Include scenario 6 in CC19 and CC20 2) Make CC19 mandatory ==> Cost will be negligible no extra simulation required (same as for CC18 and CC24) some extra work to do in result compilation only H.Bonneville, B.Jechoux, Mitsubishi ITE H.Bonneville, B.Jechoux, Mitsubishi ITE
