Wideband propagation measurements for indoor Rician fading radio channels at 62.4 GHz

Distributions of 62.4 GHz wideband propagation measurements undertaken in two different indoor radio channels to measure space-frequency correlation functions are presented. The values of 90th percentile of the coherence bandwidth at 0.9 correlation level for all locations stays below 72 MHz. Minimum and maximum B_0.9 coherence bandwidths obtained in a long narrow corridor with a directional horn transmit and an omnidirectional receive antenna are 1.10 MHz and 105.33 MHz respectively. It has been observed that the coherence bandwidth is highly variable with the location of the receiver with respect to the base station
