This paper describes the preliminary results of a research project that deals with the specification of standard test cases for the evaluation of wireless communication solutions with respect to industrial automation applications. The aim is a unified performance assessment independent of wireless technology or vendor. As a result industrial wireless communication solutions shall be classified by standardised characteristic parameters. The characteristic transmission parameters shall be determined for a target application field. Thus, the applicability of a certain wireless solution (WS) for a certain application can be easily assessed.
