Abstract This paper addresses the depolarisation effect in off-body body area networks channels, based on measurements performed at 2.45 GHz in an indoor environment.Seven different scenarios, involving both click here static and dynamic users, were considered, taking a statistical perspective.
The analysis of the cross-polarisation discrimination is performed, as well as the analysis of path loss in co- and cross-polarised channels.Results show a strong dependence of the cross-polarisation discrimination and of channel characteristics on the polarisation and propagation condition, i.e.
line-of-sight (LoS), non-LoS or quasi-LoS.Distance, varied between 1 and 6 m in the considered scenarios, is observed to have very little equi-jec 7 impact on the cross-polarisation discrimination.In the considered dynamic scenario, the channel is characterised by lognormal-distributed shadowing and Nakagami-distributed multipath fading.
Parameters of the Nakagami distribution have essentially different values in the co- and cross-polarised channels, showing a trend towards Rice in the former and Rayleigh in the latter.Based on results, a model is proposed for a dynamic off-body channel.
