The influence of the person density on the indoor MIMO channel models is experimentally investigated. The path loss is modeled as a log-distance function adding additional attenuations related to both of the distance and person density. Then, the shadowing, the root mean square delay spread, and the channel capacity are described as normal distributed random variables. Their mean value and the standard deviation are depicted as the sum of the basic values (no person in the channel) and the person density correction factors. Finally, the eigenvalues of the channel matrix are found to be a Gamma random variable with the person density dependent shape and scale parameters.
