AbstractNovember, 2009

Abstract This document updates proposed intra-cluster channel models for

TGad channel modeling On top of channel modeling presented in the last meeting in Hawaii

which focused on Living room, Vertical polarization, LOS environments with variable HPBW antenna this paper shows the restenvironments with variable HPBW antenna, this paper shows the rest for TGad channel modeling - intra-cluster channel modeling :1. Environments: extended to conference room,1. Environments: extended to conference room, 2. Polarization: extended to circular and horizontal from vertical

polarization, 3. Antenna HPBW: extended to 5, 15, 30, 60, 90 degrees,4. LOS: extended to NLOS in Living room.

By integrating the extracted intra-cluster parameters from the measured data shown in this paper and the inter-cluster channel modeling given by ref (Doc 09/334r4) the channel models for


modeling given by ref (Doc.09/334r4), the channel models for “conference room and living room environments” will be completed.
