In this paper, the authors provide the specification of a PHY and MAC layers simulator that allows evaluating the IEEE 802.11e service quality. A detailed state transition diagram is presented along with a description of the related attributes and methods, an identification of the associated events and input variables, and a description of functions for events. For validation purposes, results of the goodput as a function of the signal to interference noise ratio were obtained with an error margin lower than 10%. Higher values are found for the goodput for background and video services, mainly because the frames transmitted in these services are longer than the voice application ones.
