This paper presents the measurements and the statistical results extracted by power profile measurements of an indoor 60 GHz radio channel, to assist in the development of Wireless Broadband Systems as a part of 4G systems. The mean excess delay is in the range of 3.84 to 8.18 ns for hallways and 3.52 to 14.69 ns for offices. The rms delay spread varies from 12.34 to 15.04 ns in corridors and from 12.56 to 21.09 ns inside the offices. The coherence bandwidth varies between 13.88 and 30.49 MHz in corridors with a mean value of 22.8 MHz. Inside offices the mean coherence bandwidth is 22.80 MHz for LoS locations while drops to 7.05 MHz for NLoS. Timing jitter and standard deviation of the time delay values, remain low at all locations, and the channel does not vary significantly over 20 λ. Overall, the channel exhibits frequency selective characteristics, being extremely enhanced especially in NLoS locations.
