PA non-linearity model: TBD 3. carrier frequency offset and symbol clock: TBD 4. Receiver (and transmitter?) I/Q imbalance: TBD 3.3 Comparison Criteria PER vs SNR methodology: TBD 4.1 Traffic Models Web browsing: TBD Hard disk file transfer: TBD 4.2 Antenna Model: TBD 4.3.1 Home living room simulation scenario Minimum number of channel realizations: TBD no floor plan 4.3.2 Office conference room Model of human blockage is TBD Definition of interference: TBD 4.3.3 Enterprise cubicle Cubicle layout with TBD (randomly or fixed) location of co-channel cubes, with TBD number of co-channel cubes TBD mix of LOS and NLOS in cubicle, NLOS between cubicles, TBD mix of LOS/NLOS to AP No floor plan Eldad Perahia, Intel Corporation

Channel Models October 2009 2. General characteristics complete Channel model structure and polarization modeling for handheld devices still under discussion 3. Office conference room Complete except for support of people motion with blocking of signal paths (channel dynamics) 4. Enterprise cubicle TBD 5. Living room 6. Antenna models and beamforming Complete 7. Pathloss 7.2 office conference room: complete 7.3 Enterprise cubicle: TBD 7.4 Living room: TBD 8. Interference environment modeling: TBD Eldad Perahia, Intel Corporation

Selection Procedure No TBD’s in document October 2009 Selection Procedure No TBD’s in document In 09/935r3, presentation of new techniques occur prior to presentation of complete proposals Main issue raised in September was allowing time after presentation of complete proposals to present new techniques Eldad Perahia, Intel Corporation

Functional Requirements October 2009 Functional Requirements No TBD’s in document No comments on document since approval of first draft Eldad Perahia, Intel Corporation

October 2009 Conclusion If we want to complete the task group documents by dates indicated in the timeline, we need volunteers to address TBD’s and outstanding issues Eldad Perahia, Intel Corporation
