K-factors Primary Concerns: Solution: K-factors for model B questioned November 2003 K-factors Primary Concerns: K-factors for model B questioned Lack of LOS components in hot-spots Solution: Provided both LOS and NLOS components for all mandatory usage model environments Provided linkage between environments and which LOS/NLOS combinations to use Provided onset of NLOS modes Colin Lanzl, Aware, Inc.

Doppler Spectrum Model November 2003 Doppler Spectrum Model Concerns: Better mathematical model needed Lack of physical meaning to model No coupling between velocity and spike freq. offset Poor modeling of spike bandwidth Poor modeling of spike magnitude Colin Lanzl, Aware, Inc.

Doppler Spectrum Model November 2003 Doppler Spectrum Model Solution: Revised equation provided Linkage of vehicle velocity to spike location provided Spike bandwidth determined Spike magnitude relative to bell-shape maximum determined Colin Lanzl, Aware, Inc.

Stadium Model Added model for large outdoor stadium November 2003 Stadium Model Added model for large outdoor stadium Based on data from Moraitis et. al. Provides delay spread and cluster model Colin Lanzl, Aware, Inc.

November 2003 Validation 03/846 03/838 Colin Lanzl, Aware, Inc.

November 2003 Summary Revised channel models now provide both LOS and NLOS components for all mandatory usage model environments Revised channel model Doppler power spectrum now makes physical sense Fluorescent light channel modulation effect now modeled Stadium model added Validations available Colin Lanzl, Aware, Inc.
