Abstract

In this paper the on-body radio channel is statistically analysed at 2.45 GHz and analytically and numerically modelled at the same frequency applying different techniques. The channel exhibits great variability due to body movements with path loss data behaving in different manors depending mainly on the freedom of the communication link between transmitting and receiving antenna. Simple and accurate UTD model was applied for propagation along the body which resulted in good comparison with measurement. For more complicated on-body scenarios, conformal FDTD technique was used to evaluate received signal strength in comparison to measurement
