Comparison Of Wireless Gateway Concepts For Industrial Real-Time-Communication

Wireless industrial communication systems are increasingly deployed for process automation and sensor/actuator networks with moderate requirements on latency and reliability. Many closed-loop control systems with more challenging latency and reliability requirements would benefit from wireless communication as well and have therefore become a research field of increasing interest in recent year. In the German research project ParSec novel concepts for deterministic and highly reliable wireless communication are developed. In this paper we discuss gateway concepts to enable seamless integration of such wireless communication systems into isochronous Industrial Ethernet systems with short cycle-times of 1 ms and below.
