Ambient IoT Devices in Future Cellular Networks: A System Level Study

Ongoing discussions within 3
^rd
generation partnership project (3GPP) on Ambient IoT (A-IoT) studies are paving way towards more sustainable and energy-efficient communications for A-IoT devices. One device type under consideration is an energy harvesting device with active transmission capabilities that can harvest energy from an ambient sources. In this work, we embark on characterizing the operation of such A-IoT devices through system-level simulations, serving as an initial step in realizing the operation of these devices within the framework of 3GPP networks. Results demonstrate the importance of considering sleep state power consumption and the potential benefits of aligning energy harvesting cycle with an appropriate Discontinuous Reception (DRX) cycle for operation of A-IoT devices within the 3GPP framework.
