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.
