O direcionamento desses investimentos tem o objetivo de manter a qualidade do servi?o prestada principalmente em regi?es urbanas densas. Neste trabalho ? realizada a predi??o de s?ries temporais em rede WCDMA - HSPA dos par?metros Rx Power, RSCP (Received Signal Code Power), Ec/Io (Energy per chip/Interference) e taxa de transmiss?o (throughput) na camada f?sica. A coleta dos valores dos par?metros foi realizada numa rede em pleno funcionamento atrav?s de um drive test na cidade de Natal ? RN, uma capital do nordeste brasileiro. Os modelos utilizados para predi??es das s?ries temporais foram os de Alisamento Exponencial Simples, Holt, Holt-Winters Aditivo e Holt-Winters Multiplicativo. O objetivo das predi??es das s?ries temporais ? verificar qual modelo ir? gerar as melhores predi??es dos par?metros da rede WCDMA - HSPA. / With the growing demand of data traffic in the networks of third generation (3G), the mobile operators have attempted to focus resources on infrastructure in places where it identifies a greater need. The channeling investments aim to maintain the quality of service especially in dense urban areas. WCDMA - HSPA parameters Rx Power, RSCP (Received Signal Code Power), Ec/Io (Energy per chip/Interference) and transmission rate (throughput) at the physical layer are analyzed. In this work the prediction of time series on HSPA network is performed. The collection of values of the parameters was performed on a fully operational network through a drive test in Natal - RN, a capital city of Brazil northeastern. The models used for prediction of time series were the Simple Exponential Smoothing, Holt, Holt Winters Additive and Holt Winters Multiplicative. The objective of the predictions of the series is to check which model will generate the best predictions of network parameters WCDMA - HSPA.
