The 5G network has been under construction in Germany since 2019. The KPIs of 4G have been enhanced to enable ultra-low latency (delays) of 1 ms and 99.9 percent availability of communications services. Peak data rates of 20 Gbps, which is up to 20 times faster than 4G, can be achieved. Up to 1 million devices per square kilometer can be handled by a 5G network without performance degradation.
5G is needed above all in industrial automation. Only with 5G is the so-called 'handover' from one WLAN access point to another possible without a break, because with 5G a new connection is always established first before the existing one is terminated. In addition, applications with particularly high data volumes and many end devices that send data independently are increasingly gaining acceptance thanks to 5G.
Driverless transport vehicles (AGVs) and autonomous mobile robots (AMRs) can be deployed in large numbers without collisions in environments with 5G networks. The vehicles communicate with each other (V2V) and with the environment (V2X). Data-intensive applications such as streaming or augmented reality and IoT applications where many objects send state data are possible with 5G.
With 5G, the expected peak of global availability is in 2040. Nevertheless, work is already underway on 6G. Data transfer rates of up to 400 Gbit/s are being targeted. In China, 206.25 Gbit/s were achieved in a test setting in January 2022.
