Análise de capacidade em canais de ondas milimétricas modelados a partir da técnica de traçado de raios.

Abstract

The large number of mobile devices and the popularization of broadband applications create a scenario of ever increasing demand for data rates that the fifth generation of wireless communi- cations (5G), in particular its mobile networks, will have to provide. One of the key approaches to address this unprecedented need for channel capacity is the use of millimeter wave frequency range, between 30 and 300 GHz, which has large amounts of available bandwidth. In this context, this master’s dissertation analyzes the capacity and coverage of millimeter wave systems using a channel model based on the ray tracing technique. This method allows the estimated capacity to be mapped directly over an area of interest as a heat map, creating a simple assessment tool for rapid identification of intrinsic low quality of service zones. The results are compared with the capacity values computed with a simpler and lower computational cost method based on a path loss model. Finally, the impact of interference among cell-capable users is investigated through Monte Carlo simulations.
