RESUMO

The design of mobile broadband systems requires detailed planning due to necessity of maximizing the use of available bandwidth, network capacity, achieve minimum availability levels and minimize network implementation and operational costs. This work presents a design methodology to be employed in mobile broadband systems based on the IEEE Std 802.16-2005 (Mobile WiMAX). Here are presented the new technologies employed in the standard, the propagation model used for link budget, co-channel interference, coverage area percentage, sub-channelization gain and channel capacity calculations. Approaches for co-channel interference reduction are analyzed aiming to maximize network capacity and at the end a case study is presented using a computerized tool for mobile network planning.
