  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. Validation • 03/846 • 03/838 • 03/xxx (Vinko’s data) Colin Lanzl, Aware, Inc.

  9. 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.
