Analisis Pathloss Menggunakan COST 231-IKEGAMI Pada Daerah Rumbai Untuk Jaringan LTE

Abstract

Pathloss is losses that occur along the propagation path that are marked by a difference in the level of power received by the antenna receiver to the power level emitted by the transmitter antenna. Pathloss is caused by a barrier in the form of tall buildings, trees and the distance between the transmitter antenna and receiver antenna. Pathloss analysis is very much needed for planning and building a mobile communication system. Because it can know the characteristics of propagation and predict the receiver's antenna receiving power level. Thus the communication system designed can be in accordance with the expected performance. In this study, we will estimate path losses on the LTE network in the tassel area. The modeling used is COST 231-Ikegami. This model is chosen because it not only produces the amount of pathloss prices as the output of the calculation process, but also loses empty (L0), surface losses (Lmsd), and diffraction losses on the roof and scattering (Lrts). ) Pathloss measurements were obtained through measurement of mobile phone receiving power with the drive test method at 1800 MHz frequency. From the results of the MSE (Mean Square Error) data, the value of 21,02 is obtained.
