Abstract (english): For certain medical applications, e.g. capsule endoscopy, high resolution images need to be transmitted from the inside of the human body to an on-body receiver. Ultra wideband communication is widely considered a feasible alternative to today's available products operating with narrowband communication to increase the data rate. However, up to now it is unclear which data rates can be achieved in an ultra wideband communication scenario for humans with different physiological properties. This limit can be quantified by calculating the channel capacity. Based on a channel model developed specifically for in-body communication in the ultra wideband frequency range, we determine the transmission loss and the channel capacity for a capsule endoscope scenario in different human body voxel models with different physiological properties. Our results show that the channel capacity mainly depends on the waist circumference as well as the muscle to fat ratio in the abdominal area. For five receive antennas, using a selection combining scheme, the 10 %-outage capacity differs by one order of magnitude depending on the physiology. Furthermore, the number of receive antennas plays a critical role in achieving improvements compared to today's narrowband communication.
