**8. Summary**

This chapter describes features of the UWB channel that should be taken into account when it is being considered for medical applications, in particular in hospital scenarios. These scenarios include cases where the human body is in motion. Using actual measurements mathematical models of the channel have been proposed.

It is also possible to use UWB technology to measure the workings of medical implants or body activities. This chapter presents the case of the response of an artificial aortic valve to UWB waves and its potential use to evaluate the working status of the valve.

Finally there is a brief discussion of engineering standards applicable to the use of UWB technology in the medical field.
