PENGARUH POLARISASI DIVERSITY TERHADAP BITRATE PADA OPENLTE SISTEM

Abstract

The main challenge for mobile wireless operators is to ensure that users consistently receive smooth and reliable
services. One of the crucial components in the development of wireless technology is the antena. The aim of
this research is to understand the impact of polarization diversity on bitrate in the OpenLTE system. Multiple
Input Multiple Output (MIMO) antenna system can enhance capacity and transmission speed in communication
systems. OpenLTE features include a simple eNodeB with integrated Evolved Packet Core, tools for scanning
and recording LTE signals based on GNU Radio. In this study, an analysis is conducted on the effects of MIMO
antenna polarization arrangements using Co-Polarization and Cross-Polarization configurations. The research
indicates that the antenna configuration significantly influences the amount of bitrate and Signal to Noise Ratio
(SNR) produced. The Cross-Polarization configuration can achieve a relatively high bitrate of 38 Mbps during
service activities, compared to Co-Polarization, which only yields 28 Mbps in terms of birtare.
