Wireless Networked Control Systems is becoming an important topic in the context of factory automation. In this paper, a workcell is studied where the 802.11 standard is used as the communication protocol. The focus is on the effect of different types of motion on the packet end-to-end delay. OPNET simulations indicate that motion does not violate the delay requirements for the proposed model. Since noise in the ISM band can affect wireless communication in the cell, the maximum permissible WiFi noise is found.
