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 Eldad Perahia, Intel Corporation

Other considerations Coordination with TGac Coexistence Usage models January 2009 Other considerations Coordination with TGac Usage models In 08/1395: MAC functions, for example “Session mgmt” (seamless fallback from VHT60 and/or VHTL6 to 802.11n to legacy) Aggregation to support larger data units Space-time channel management Coexistence Liaison with 802.15.3c Liaison with 802.19 Eldad Perahia, Intel Corporation
