COMPOSITE RECONFIGURABLE WIRELESS NETWORKS: THE EU R&D PATH TOWARDS 4G vision requires the creation of new wireless technologies and system concepts offering easy-touse interfaces with the user at the center, as in the ambient intelligence [1] and pervasive computing [2] paradigms. In the scenarios envisaged for future smart environments the user needs to manage electronic information easily by having complete access to time-sensitive data, regardless of physical location. Short-range wireless

While the majority of human-to-human information exchanges are still by voice, a rapid increase in data transfers is observed in other types of links as manifested by the rising need for location-aware applications and video transfer capability within the home and office environments. In the future, we expect the need for even higher data rates to develop jointly with a flourishing increase in large numbers of low-rate wireless devices embedded in common appliances, sensors, beacons, as well as identification tags, spontaneously interacting in ambient intelligence networks. Against this background, the commercialization of wireless devices based on the principles of ultra-wideband (UWB) radio technology (UWB-RT) is widely anticipated, given the recent endorsement by U.S. regulators [3] . UWB-RT could play an important role in ABSTRACT An unprecedented transformation in the design, deployment, and application of shortrange wireless devices and services is in progress today. This trend is in line with the imminent transition from third-to fourth-generation radio systems, where heterogeneous environments are
