2. Objective
Highlight and remove inconsistencies between Comparison Criteria ( r25) and baseline documents (PAR and 5 criteria)

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.

5. CCs vs PAR (1/2) TGn PAR clearly prioritised 3 environments:

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

CCs vs PAR (2/2)
TGn PAR targets new market segment :
“The purpose of the project is to improve the 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 n targets are expected to be QoS oriented

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

8. Quick (and clean) fix 2 steps: 1) Include scenario 6 in CC19 and CC20

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
