Abstract
Recently, it has been proposed the use of WiMAX for the return channel in digital television systems, but using a new frequency profile around 700 MHz. This work presents some simulation results of models designed to determine the system capacity concerning the number of active subscriber stations, and according to specific proposed scenarios, traffic sources profiles, and specific propagation and coverage conditions. The results presented in this work provide elements to determine the suitability of WiMAX technology as the return channel for the majority of interactive digital television applications. It also presents some conditions that must be observed for this intended application.
