Wireless communication between distributed systems will be essential in the production world of Industry 4.0 in the future. Extremely low latency with low distortion (jitter) needs to be achieved to enable complex processes to be regulated and controlled. High communication reliability levels must also be established for environments with a high device density. Wireless systems currently used in industry such as WLAN® and Bluetooth® do not meet the real-time requirements at all, or only to a very limited extent, and also work in the already congested 2.4 GHz frequency band which has had to be heavily regulated with mechanisms such as Listen Before Talk (LBT), thereby limiting further application possibilities. This means that other future possibilities such as tactile man-machine interfaces or "augmented reality" will only be possible with new wireless technologies which ensure high data rates with extremely low latency.
The "Reliable Wireless Communication in Industry" research programme (ZDKI), which is funded by the Federal Ministry of Education and Research, examines well-known limitations, explores new wireless technologies and develops solutions and concepts aimed at meeting exacting real-time requirements. Eight independent research consortia from industry and science are addressing this problem based on different use cases from industrial practice.
The eight projects are coordinated by the "Reliable Wireless Communication in Industry Accompanying Research" (BZKI) consortium. This ensures that results are transferred inside and outside the support programme. The findings are consolidated in the form of standardization activities and, under the name „INDUSTRIALRADIO.
DE“", support the excellent reputation of "Made in Germany" products.
The DKE is supported in coordinating the accompanying research and the eight projects by the consortium partners: Institut für Automation und Kommunikation e. V. Magdeburg (ifak), Dresden University of Technology, Technical University of Kaiserslautern and Center for Computing and Communication Technologies (TZI) at Bremen University.
