This paper presents an approach to the estimation of mean path loss model parameters in off-body Body Area Networks channels. In this approach, the path loss exponent is constrained to a value obtained from line-of-sight (LoS) propagation in the copolarised channel, considering a generalised static scenario. The proposed approach is compared to alternative ones, by evaluating the coefficient of determination for a set of measurements obtained in an indoor environment. Compared to a traditional approach, a relative improvement of up to 0.7 and typically above 0.4 is observed in the LoS case, while the goodness of fit is unchanged for the non-LoS case.
