Study of a Self-Powered UWB Sensor Network for Industrial Applications

This paper presents initial results regarding the potential of ultra-wideband (UWB) technology to become an enabler of self-powered industrial sensor networks. Our study uses requirements from vibration monitoring typically implemented today with wired installations. A wireless solution can significantly reduce cost if batteries do not need to be replaced often. We discuss the key factors extending network lifetime. A charge balance analysis shows that UWB is a well-suited technology for this application. Evaluations of the network lifetime at different network operating points and against alternative wireless technologies support our statement.
