One widely considered technique to achieve this is ultra wideband transmission. To the best of our knowledge no comprehensible channel models exist for the scenario of in-body communication. To change that, we recently proposed a simplified layer modeling technique. The goal of this paper is to verify that the resulting channel characteristics derived with our proposed method are on average similar to those obtained from numerical wave simulations. Our results show that on average the transmission loss for both approaches is nearly the same. Moreover, the correlation between the transfer functions is very strong. Finally, the power delay profiles generated are almost identical. Hence, it is possible to create a channel model with the same characteristics using a much simpler and less computationally expensive approach.enbody area networkschannel modelingpropagationultra widebandConference Paper10.23919/EuCAP48036.2020.9135892Other
