Influence of human motion on indoor wireless millimeter-wave channel characteristics

Channel variations due to movement of people are expected to be particularly significant in the SHF/EHF bands. This paper reports CW measurements performed at 30.1 GHz between two fixed terminals in a single room to determine the amplitude and speed of temporal variations of the envelope when individuals are moving in the environment. In particular, it is shown that the importance of fluctuations is dependent not only on the degree of movement but also on the spatial fading situation when the room is empty. Results also indicate that reflections onto persons are significant and will have to be considered in developing a statistical model of the channel
