Requirements and current solutions of wireless communication in industrial automation

The industrial wireless automation sector exhibitsa huge market growth in the last years. Today, many applicationsalready use wireless technologies. However, the existingwireless solutions do not yet offer sufficient performance withrespect to real-time and reliability requirements, particularlyfor closed-loop control applications. As a result, low latencywireless communication technologies will bridge the gap andcan become a key factor for the wide-spread penetration ofwireless in industrial communication systems. It is therefore themain goal of this paper to provide a comprehensive overviewon requirements, current solutions, and challenges as well asopportunities for future wireless industrial systems. Thereby,presented requirement figures, analysis results, and performanceevaluations are based on numerous practical examples fromindustry.
