System Loss Model for Body Area Networks in Room Scenarios

Abstract

This paper presents an analysis of system loss in Body Area Networks for room scenarios, based on a wideband measurement campaign at 5.8 GHz. The measurements were performed with a fixed antenna transmitting vertically and horizontally polarised signals, while the user wears dualpolarised antennas. The average system losses in co- and crosspolarised channels are 41.4 and 42.6 dB for vertically polarised transmitted signals and 41.8 and 45.0 dB for horizontally ones, showing that polarisation plays a role in the radio channel. Analytical models for the average and standard deviation of system loss are presented, with a linear dependence on user mobility, on transmitted/received polarisation, and on link visibility and dynamics. Overall, a good fit between model and measurements is obtained, with a mean square error of 2.3 and 0.12 dB for the average and standard deviation, respectively.
