2nd Place Best Paper Award at IEEE World Forum on Internet of Things

We are very happy to announce that the CNI Researchers Pascal J├Ârke and Christian Wietfeld have received the "2nd Place Best Paper Award" for the paper "How Green Networking May Harm Your IoT Network: Impact of Transmit Power Reduction at Night on NB-IoT Performance" at the IEEE World Forum on Internet of Things (WF-IoT) 2021.

This paper is a joint work of the Collaborative Research Center (SFB 876) and PuLS project. Longterm measurements of NB-IoT signal strength in public cellular networks have shown that at night in some cases base stations reduce their transmit power, which leads to a significant performance decrease in latency and energy efficiency by up to a factor of 4, having a substantial impact on battery powered IoT devices and therefore should be avoided.
