Propagation characterization of wideband indoor radio channels at 60 GHz

This paper presents the results of indoor propagation measurements performed in a corridor (LOS) and a hall with both LOS and NLOS measurement routes at 60 GHz. The channel dispersion and fading effects are analyzed by examining the rms delay spread, path loss and shadowing. Moreover, the correlation properties between dispersion and fading effects are investigated, and negative cross-correlation is found between rms delay spread and shadowing fading. An upper-bound exponential model of rms delay spread and path loss is developed for estimating the worst case of rms delay spread at given path loss
