Abstract EN
The standard of in-body communications is limited to the use of narrowband systems.
These systems are far from the high data rate connections achieved by other wireless telecommunication services today in force.
The UWB frequency band has been proposed as a possible candidate for future in-body networks.
However, the attenuation of body tissues at gigahertz frequencies could be a serious drawback.
Experimental measurements for channel modeling are not easy to carry out, while the use of humans is practically forbidden.
Sophisticated simulation tools could provide inaccurate results since they are not able to reproduce all the in-body channel conditions.
Chemical solutions known as phantoms could provide a fair approximation of body tissues’ behavior.
In this work, the Time Reversal technique is assessed to increase the channel performance of in-body communications.
For this task, a large volume of experimental measurements is performed at the low part of UWB spectrum (3.1-5.1 GHz) by using a highly accurate phantom-based measurement setup.
This experimental setup emulates an in-body to in-body scenario, where all the nodes are implanted inside the body.
Moreover, the in-body channel characteristics such as the path loss, the correlation in transmission and reception, and the reciprocity of the channel are assessed and discussed.
