Low Power FM-UWB Transmitter for Wireless Body Area Networks

Abstract

Among the most challenging wireless area networks, is the emerging WBAN (Wireless body area network) which is a network of implanted and/or body-worn sensor nodes that collect, process, and transmit to base station (or remote receiver) vital signals such as blood pressure, heart-rate, glucose, and even brain signals. WBAN is used to monitor the health status of the patient and wirelessly transmit the outcomes to the physician to reduce the load at hospitals and increase the efficiency of healthcare services. However, WBAN is a portable network. Successfully implementing such networks faces many key challenges. Battery lifetime in surgically implanted devices is the biggest challenge as the network has to last for years. So, establishing an energy efficient wireless link is strongly required to achieve long-lifetime battery use.
