The 450 MHz frequency as a forerunner of the energy transition

The energy transition requires a conversion of the entire energy system. Central structures break up and are replaced by small-scale and decentralized units. This will fundamentally change the requirements placed on network operators in order to continue to guarantee a safe and reliable supply. Since the energy supply is a critical infrastructure, there is a certain pressure to act with a view to maintaining the overall economic and social task to be performed. This article analyzes the change in the energy system, particularly with regard to reliability and the associated measures to be taken. An integrated connection of the generators and customers is essential and requires a robust, reliable and cost-effective telecommunications infrastructure. Various technologies are available for this, some of which differ significantly in their properties (e.g. availability, data rate or latency). In our analysis, we compare the individual technologies with the requirements of a decentralized energy system. It turns out that for the purposes of the energy industry, a radio solution based on the 450 MHz frequency seems particularly well suited to meet the challenges.
