Análisis comparativo de un sistema de transmisión digital mimo 2X2 versus mimo 4X4 para una BS SMA en el Centro de Quito

Abstract

This analysis includes a description of the Pre Swap 2T2R and Post Swap 4T4R for a MIMO system for LTE technology, AWS band with 2100MHz frequency, channel 2250 with a 20MHz bandwidth and modulation of up to 64QAM of the "Station X" located in the Center of Quito. Each of these tests carried out through a test car in motion, carrying a mobile test terminal station with P30 pro mobiles, Global Positioning System (GPS), a Windows compatible PC and with the data collection system of Pre-Process, in addition to the use of an EX Flex Scanner that works in the E-ULTRA 4 Band, which infers in the same assigned for LTE. This handling is oriented to reflect the real-time performance experienced by the UE being in motion when receiving the signal emitted by the evolved node base station (eNodeB), it is carried out post-processing with the Genex Assistant software and from the tables obtained in This medium is processed in the MAPINFO Pro 16.0 software to observe the route traveled, each of the data is reflected according to the target levels established by the ITU as good levels of operation, these RF measurements will be based on the parameters RSRP, SINR, RSSI, RSRQ, CQI, range indicator, transmission mode and performance level.
