In this short communication we focus on the Contention Window mechanism of 802.11e EDCA. We first show that existing analyses for this mechanism rely on a system of equations that does not always have a unique solution. Next, we present an alternative analysis for which we prove mathematically the existence of a unique solution. Finally, we validate the accuracy of our analysis by means of simulation results.
