摘 要：Wireless Body Area Networks (WBANs) are expected to promote new applications for the ambulatory health monitoring of chronic patients and the elderly population, aiming to improve their quality of life and independence. These networks are composed by wireless sensor nodes that measure physiological variables and transmit it, for example, to the patients' smartphone, which may acts as a gateway to a remote medical assistance service. A key element of such sensor nodes is the wireless transceiver as it often dominates the overall power budget. Therefore, to provide a high degree of energy autonomy, wireless transceivers with an ultra low power consumption are needed. In this book, a transceiver architecture and implementation is presented, which targets such highly power constrained applications and employs the Bluetooth low energy standard.
