Análisis de métricas basado en esquemas de reúso fraccional de frecuencias y planificación de tráfico en ambientes macro-femto celdas en la tecnología LTE

Abstract

The present project, we analyze the metrics based in fractional frequency reuse schemes (reuse1, reuse-3, PFR, SFR) and traffic planning (Max_SNIR, Round Robin, Proportional Fair) by using the simulation software ICS Designer of the macro-femto cell network with LTE technology deployed in each environment of Quito. Initially, a description of LTE cellular technology and femtocell technology is made, considering its evolution, architecture and development. In addition, the configuration of the parameters necessary for the simulation of the LTE network deployed in Quito’s city, through the ICS Designer software is detailed, after that, the choice of study environments is made. Afterwards the system performance is subsequently evaluated through metrics such as: coverage, performance, signal quality and signal-to-interference plus noise ratio by FX TX / RX, RSRP, RSRQ, SNIR and Montecarlo coverage simulations of each chosen environment. Finally, the results obtained are presented for the proposed schemes of fractional frequencies reuse, and for the simulation of the traffic planning schemes, the universal frequency reuse scheme was considered.
