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.

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 :
“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, while most of foreseen new market segments will require QoS support.
 Optional CC 19 does not satisfy the PAR.

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
2) Make CC19 mandatory
 Cost is negligible
Requires no extra simulation
(same as for CC18 and CC24)
Some additional effort to compile results
