Simulation of millimetre-wave channels for short-range body to body communications

Operating short-range body centric communications at millimetre-wave frequencies will offer a number of key benefits, most notably high data rates potentially in excess of 2 Gb/s. However, development of compact, portable, bodyworn channel sounding equipment presents significant challenges at these frequencies. As an alternative method to characterising channel conditions for millimetre-wave applications, we present the steps taken to simulate body centric channels using animation software and a ray tracing algorithm. Using soldier-to-soldier communications as an example, a number of important channel metrics such as root mean square angle and delay spread are investigated.
