The authors have characterized the effect of human presence on path gain and time dispersion over Ultra Wide Band (UWB) channels within the passenger cabin of a typical midsize airliner. They measured a few hundred channel frequency responses over the range 3.1 - 6.1 GHz between various locations within a Boeing 737-200 aircraft, with and without volunteers occupying the passenger seats. The links were deployed in a point-to-multipoint configuration with the transmitting antenna along the centre-line of the forward part of the cabin at either the ceiling or headrest level and the receiving antenna at the headrest or armrest level at selected locations throughout the rest of the cabin.
