Simulative performance analysis of IO-link wireless

Abstract

Control applications in factory automation utilizing wireless technologies require well-defined and constant communication performance with respect to cycle time, determinism and availability. These requirements are hard to meet using standard wireless communication technologies in the presence of interferers and challenging fading channels. The recently emerged new standard IO-Link Wireless was tailored to target the required performance characteristics even in densely populated 2.4 GHz ISM band. This work intends to verify by simulative analysis, that the performance indicators meet the target performance. For this purpose, a MATLAB-based simulation framework utilizing IEEE802.11 TGn and interferences with real life active profiles was developed and then used on IO-Link Wireless specification relevant test scenarios.
