The topic in this paper deals with the performance of a multi-input multi-output multi-path dissipating medium in indoor cellular computer network environments on the basis of the IEEE 802.11n channel model. The MIMO multipath fading channel system utilized for this study comprises four transferring and accepting aerials and incorporates the Bell Doppler spectrum object. The channel model encompasses six distinct outlines marked A through F, that cover various schemes such as flat and large areas, fields, small and large offices, indoors and outdoors. Every medium incorporates a fading model containing shadowing and MIMO multi-path decaying, taking into account the distribution of multiple delays, spatial power, K-factor dispersal, and Doppler range.
