Power delay profiles for a wireless endoscopy link

In this work, we investigate power delay profiles for a wireless in-to-out-body endoscopy link. A hospital scenario is considered where endoscopy images taken inside the body are wirelessly transmitted to a monitoring device outside the body. We distinguish between a direct in-to-out-body link and a dual-hop relay link where the image data is first sent to an on-body hub device. Path loss for the direct link is found to be fairly high to allow for reliable communication. It is argued that the dual-hop relay link is a better option because it offers options to alleviate the path loss issue, such as amplification or retransmission of data.
