Networks known as WiFi (IEEE 802.11 standard) are widely used in applications ranging from simple home environments systems to complex control systems network. However, the extensions incorporated into the standard to provide Quality of Service (QoS) are still unable to guarantee time constraints for real-time (RT) communications requirements. This paper presents an experimental validation of the RT-WiFi protocol that was recently proposed and analyzed through simulation. The experimental results demonstrate the feasibility of implementing the RT-WiFi protocol and improving the QoS level of communications through a comparative analysis with the EDCA mechanism, which is a mechanism incorporated in the IEEE 802.11 standard to provide different levels of transmission priority of different types of traffic.
