UWB Path Loss Models for Ingestible Devices
IEEE Transactions on Antennas and Propagation, 2019 [EN] Currently, some medical devices such as the Wireless Capsule Endoscopy (WCE) are used for data transmission from inside to outside the body. Nevertheless, for certain applications such as WCE, the data rates offered by current medical frequency bands can result insufficient.
