Abordagem histórica, funcional e projeto de cobertura LTE (4G) para Arena da Amazônia

Abstract

In this research work, the study of technologies of the Fourth Generation (4G) is developed, knowing the evolution of telephony and its applications. In recent years, the increase in demand for data services on cellular networks is something expressive. Applications using mobile devices to perform high data file downloads, accessing the internet, has become essential in the lives of a good portion of the world's population. Mobile broadband is currently the most used service, users all the time exchanging information, photos, videos and video calls in real time. In this scenario, it becomes imperative that mobile networks offer high transmission rates to users, in addition to great coverage for these services. Initially, there were the GSM (Global System for Mobile) and UMTS (Universal Mobile Telecommunications System) networks that did not support the new market demands. It was with this need in mind that the LTE (Long Term Evolution) system was designed to improve the network, consequently the end-user throughput, as well as reducing latency. So, offering high rates of downlink and uplink, using Access technologies such as OFDM (Orthogonal Frequency–Division Multiple Access) and with the evolution of this technology, MIMO (Multiple-Input Mutiple Output) is used, which increases the capacity of Radio Frequency (RF) systems. Thus, emerging various technologies, such as WiMAX, which is a wireless access technology, which uses the coverage in cell format as in cellular telephony, thus making it possible to transmit the base station to, for example, user devices. This work employs these premises as a motivation to apply it in simulations referring to LTE networks using the Radio Mobile software.
