3. TG documents January 2009 Functional Requirements
Similar to 11n document
PAR
Additional quantitative constraints
Evaluation Methodology
Combine best from both 11n’s usage model and comparison criteria documents
11n defined dozens of comparison criteria that were ignored
11n defined dozens of environments, use cases and applications, but in the end mainly focused on three simulation scenarios
Discuss usage models and then define limited set simulation scenarios for MAC simulations
Include point-to-point link test for functional requirements
Define PHY simulations
Physical layer impairments
Define metrics
Channel Models
Impulse responses
Path loss
Antenna
Define model per simulation scenario environment

Other considerations
Coordination with TGac
Usage models
In 08/1395:
MAC functions, for example
“Session mgmt” (seamless fallback from VHT60 and/or VHTL6 to n to legacy)
Aggregation to support larger data units
Space-time channel management
Coexistence
