Low-Power radio communication

Reducing power losses and increasing the efficiency of systems is one of the most effective, but also one of the most challenging levers in the field of sustainable, climate-friendly electronics. In an increasingly connected world with billions of sensors, the energy supply of these components is a relevant factor in our living environment and for industrial applications. In addition to improving the ecological footprint the minimization of the energy demand, by using power efficient radio protocols, is the key to extend the run-time of wireless sensor nodes. This goes hand in hand with a significant minimization of maintenance cycles in wireless sensor networks, thus reducing also the costs. In battery powered devices or in applications with energy harvesting, lower energy demands also help to minimize the system by using smaller batteries or by using other energy harvesting concepts than solar-based approaches. This opens up many new application possibilities. Furthermore, small currents and voltages help to improve electromagnetic interference.

Building on the previous online-session, where an overview on low-power system design was given, in this session we will focus on low-power radio communication, as it significantly contributes to the energy demand in wireless sensor networks. This session will present a holistic approach to optimizing radio communications from a system point of view. Starting from the component selection and design considerations to energy management on the firmware and adaptive algorithms, the session covers the many different aspects of optimization with regard to low-power radio communication.
