Although the medical implant communication service (MICS) band is a good candidate for implant applications, there are no models for in-body to out-of-body channels in this frequency band. The real experiment with an implant antenna is difficult. So, an approximate test is done using an on-body antenna covered by a layer of fresh meat. Three scenarios of heart implant-walking, wrist implant-walking and heart implant-realistic are considered. Short-term and long-term fading were decoupled. Stationarity tests state that both of the walking scenarios are stationary where the realistic scenario that includes sitting down and standing up in random times and orientations is non-stationary. Several distribution functions were tested to fit with the short-term and long-term data. The results show that the short-term fadings of heart and wrist implant-walking scenarios are best described by normal and Weibull distributions respectively, where the log-logistic distribution describes the long-term fading of walking scenarios best.
