The initial analysis of the WiMAX uplink interference problem indicates a dependence upon a process (scheduling) which cannot be modeled accurately. Given this, one might therefore consider a Monte Carlo approach. However, further analysis shows that the details of this dependence are not relevant to the engineering question. One can treat the scheduler operation as a stochastic process and concentrate instead on the elements of the problem which are well defined and easily calculated using traditional RF simulation techniques. For these reasons EDX's straightforward calculation approach, beginning with a fixed traffic definition, and evaluating the frame stochastics directly results in a fast and efficient algorithm that produces a reliable, consistent, and practical result.
