Biomedical devices benefit from the recent and rapid growth of wireless technology for measuring physiological signals for both implantable and wearable systems. The use of wireless in healthcare systems provides great mobility and increases comfort level of patients by freeing them from hospital equipments. However, it is important to select a proper and safe wireless band for medical data transmission as it is crucial for the patient’s safety. Historically narrow band wireless technologies have been used in medical monitoring widely. This chapter introduces the use of wideband technology for future medical monitoring systems. The important parameters of the wideband technology are its low power transmitter design, low-interference effect in medical environment and high data rate capability. The chapter describes low power implementation of ultra-wideband (UWB) and applies the technology to some emerging biomedical applications.
