Saed Abughannam (Department "Circuit Technology") successfully completed his doctorate on the topic "Low-power Direct-detection Wake-up Receiver at 2.44 GHz for Wireless Sensor Networks" under Prof. Christoph Scheytt. Congratulations on this achievement!
Summary:
This thesis investigates the design, implementation and metrological characterization of a special radio receiver, the so-called wake-up receiver (WuRx), at 2.44 GHz. The WuRx can be used in wireless sensor networks (WSN) to reduce the energy consumption of network nodes and extend battery life. Wireless sensor nodes are often powered by batteries, making power consumption the biggest challenge in the development of WSNs. If each WSN node contains an integrated WuRx that is always on and waits for a wake-up signal from other nodes or the base station, the communication scheme will be greatly simplified and more reliable, and energy consumption will be significantly reduced.
