End-to-end coexistence tests in an interworking UWB-UMTS platform

Abstract

In the last years, UWB (Ultra-Wide Band) technology has been widely studied, thanks to its attractive features like low power consumption or high data rates. On the other hand, the coexistence issue has delayed the regulatory process in Europe and its development and introduction in the market. A peaceful coexistence is essential, not only for guaranteeing other radio services, but also for enabling the development of UWB applications interoperating with other wireless networks. Thus, interconnecting in the same device UWB and mobile network interface, like UMTS, will allow to widen the scope of WPAN applications, limited by the short range of UWB coverage. In this paper will be exposed the work performed in the development of an interworking platform between UWB and UMTS, which has allowed to carry out several coexistence tests, where UWB and UMTS was collocated in the same device.
