TGT Purpose
To enable testing, comparison, and deployment planning of WLAN devices based on a common and accepted set of performance metrics, measurement methodologies and test conditions
This includes identification of useful performance metrics
Output captured in Recommended Practice
Many identified metrics may not be defined in standard

WNM Purpose
To effect a complete and coherent upper layer interface for managing devices in wireless networks
Device management means restricted to items within a STA (or AP).
Management to include configuration management, resource management, access and security management, and performance management.
In each case the "management” implies the need for monitoring and control of STA parameters.
Certain TGt metrics may be candidates for standardization as new management parameters in STAs.

TGt metrics for WNM
TGt will identify relevant metrics, sub-metrics and parameters useful for performance testing and performance prediction.
Any metric or sub-metric should be included in WNM amendment IF:
It is not already defined in the standard AND IF
It affects STA or network performance OR IF
It is a test configuration control parameter which should be standardized in all STAs to permit uniform testing.
WNM will implement measurement or reporting of metrics for management.
WNM will provide monitoring and control of parameters for management.

6. Parking Lot for Metrics and Sub-metrics
Propose that as metrics are identified and classified, a WNM “flag” be used to indicate which metrics should be added to the standard.
Performance metrics by OSI model layers
Data Link
Application
Transport
Physical Layer

TGt - WNM Coordination
TGt’s schedule leads WNM’s significantly, so timeline supports TGt output--->WNM.
Propose that relationship be informal
TGt attendees may input contributions to WNM
WNM attendees may base contributions on TGt work
Attendees of both groups would be ideal volunteers for this effort
Attendees from InterDigital, Microsoft and other companies will promote this work.

Conclusions
TGt work will identify metrics and parameters useful for performance testing, prediction and for management.
TGt’s Recommended Practice output document cannot standardize any new metric or parameter within STAs.
WNM is tasked with amending the standard for management purposes.
It is expected that certain metrics identified for testing and prediction in TGt should be standardized for management in WNM.
