Abstract
Ultra Wide Band (UWB) technology has been developed in the last years in the framework of short-range low data rate communications. Due to the wide channels bandwidth and low power characteristics it provides a very different approach to wireless technologies compared to conventional narrow band systems. This makes it interesting in medicine area with many potential applications. In this chapter, the discussion is focused on the application of this technology in medical monitoring, and Wireless Body Area Networks.
UWB signals are moreover naturally suited for accurate estimation of the distance between two radios even in severe multipath or non-line-of-sight scenarios, virtually enabling indoor position sensing with an accuracy of 50 cm or better. This features can be exploited to realize a patient motion monitoring system in hospital.
Moreover, one of the key advantages of UWB in this context is its potential for the development of ultra low power consumption radio chipsets, resulting in significantly increased battery lifetimes for sensor nodes spread in the environment or even autonomous operations from waste energy. The recently developed IEEE 802.15.4a standard is capitalizing on these two advantages of UWB, and it is expected to enable the combination of accurate position sensing and ultra low power communications in one single system.
