The following paper presents approach for wireless transmission system development in time critical environment. Proposed approach uses system’s dynamic characteristics. Such information allows predicting data transmission bottlenecks on early development stage. This in turns shortens overall development time, by reducing the number of backoffs. Dynamics processing is based on Hammerstein model. Which proposes splitting up system on components, that isolate dynamic/static and linear/nonlinear properties. It allows creating an analytical representation of a system, by using low amount of parameters. System’s response is analyzed by treating multiple data flows to model input. The most valuable analysis type is checking boundaries of parameters. The analytical model allows a low effort adaptation to systems architecture changes. The proposed model was tested on real industrial object, with three distributed control stations and more than one hundred sensors/actuators. Created model approved possibility of using wireless communication and pointed out bottlenecks.
