Concept for Controller-Based Coexistence Management of Diverse Wireless Communication Systems

Modern production facilities are increasingly optimising production performance and quality. This results in the need for real-time access to interconnected entities to enable the organisation and control of the entire production chain in industrial environments. Wireless communication systems are widely used to connect different machines, e. g. moving parts, which normally do not allow wired connections. The increasing use of diverse wireless systems will result in more devices using
the limited shared wireless medium, leading to interference between involved wireless entities. To ensure coexistence, i. e. meeting the communication and functional requirements of all applications, coexistence management is essential. Therefore, this paper presents a new concept for automatic controller-based coexistence management, which considers three dimensions (i. e. frequency, time and location) of wireless communication. This leads to an increased number of applications being able to communicate in parallel, while still meeting their requirements.
