Low-power Radio Design for the IoT
School of Engineering > MicroEngineering
Abstract
One of the basic function of an IoT node is to collect data, process it and send it to the cloud through a wireless channel. Despite the scaling of CMOS technology and the progress made in low-power circuits, today, the power consumption of IoT nodes is largely dominated by the wireless communication and particularly by the radio. It is therefore key to understand the various trade-offs faced when designing a radio embedded into an IoT node.
Smart sensors for IoT
School of Engineering > MicroEngineering
Abstract
One of the basic function of an IoT node is to collect, process, store and eventually send the collected data to the cloud. Therefore, sensors and the related sensor interface are key components in the IoT node. Additionally, the IoT node is constrained to very limited space (or volume) and energy. Hence, the sensors and its related interface have to be highly miniaturized and very energy efficient.
