This paper presents a general empirical system loss model for estimating propagation loss in Body Area Networks in off-body communications at 2.45 GHz in a passenger ferry environment. The model is based on measurements, which were carried out in dynamic scenarios in the discotheque passenger ferry environment. The model consists of three components: mean system loss, attenuation resulting from the variable antenna position on the human body, and attenuation due to fading. Preliminary results for system loss components in dynamic scenarios in the discotheque environment are presented. The components of mean system loss and variable antenna position attenuation are modelled by using a linear regression. The obtained root mean square error for the mean system loss is lower than 5 dB. The fading components are modelled by Lognormal and Nakagami-m distributions.
