Abstract :
Body Area Networks (BANs) are part of the incoming future in wireless communications. A full wave simulator is used to analyse the propagation channel between nine on-body antennas, at 2.45 GHz, in dynamic scenarios (walk and run). The movement is generated by an animation software, using a realistic shaped homogeneous phantom. The correlations between channels and their power distributions are investigated when the user is moving. Transmitter locations on the sides (for instance, on the arms), combined with non Line-of-Sight (NLOS) or quasi- LOS receiving links, were found to be the theoretically most favourable for MIMO.
