A characterization of the fading observed in an 8-node wireless body area network in an outdoor environment is presented. When the user was stationary the degree of fading for on-body links was found to be low, with estimated Nakagami m parameters >> 1. However, when the user was mobile, depending on the body dynamics in the vicinity of the node location and transmission path length, fading significantly increased, characterized by lower m values. Level crossing rates are also presented and used to estimate the maximum Doppler frequency for each individual on-body channel.
