Análise e simulação dos aspectos de transmissão de sinais 5g em macrocélulas em ambientes urbanos

Abstract

Currently, the growing demand for higher data transmission rates has become a point of interest for large companies and providers. Current services and applications such as Internet of Things (IoT), e-commerce, industrial automation based on Industry 4.0, expansion of IPV6, applications that require high throughput in real time, cloud computing are becoming increasingly implemented. In order for the qualitative factors of these applications to be achieved, the implementation of new technologies to the detriment of past ones, becomes something crucial to meet the needs employed by the new demands. As a potential solution to these demands, the fifth generation of cellular mobile telephony (5G) has the prospect of expanding the capabilities of data rates applied to mobile data connections. In addition, 5G aims to provide greater connectivity and area coverage (even in remote locations) and reduced latency in transmissions. Thus, in view of this very current field of study, this course completion work aims to study aspects of propagation of 5G signals in the 3.5GHz band (one of the bands defined by Anatel for technology in Brazilian territory), using the urban scenario of high density of users with enhanced broadband connection (eMBB), applied in the city of Patos de Minas – MG. Evidently, the obtained results show the capabilities of the modulation orders reached for up to 256-QAM using the PDSCH downlink physical channel, in the different scenarios without correction and with correction of the downtilt angle, applied to the Freespace and Close-in propagation models, making it possible, with the use of aggregated carriers and MIMO layers, to reach peak data rates greater than 1Gbps given conditions of BER lower than 10^(-6).
