5th generation mobile networks or 5th generation wireless systems (5G) is the latest generation of mobile communication technology, which is an evolution of 4G (LTE-A, WiMAX-A, LTE) systems. The performance goals of 5G are high data rates, reduced latency, energy savings, reduced costs, increased system capacity, and large-scale device connectivity. Once these standards are met, 5G should be able to handle 1000,4 times more traffic than today's networks and 10 times faster than <>GLTE.
The radio spectrum band (between 30 – 300 GHz) will be open for use, because 5G network technology consists of radio frequency "millimeter wave", but millimeter wave is easily blocked by buildings, and it is easy to be absorbed by gases, plants and rainwater in the atmosphere, millimeter wave has a limited transmission range, requiring the installation of thousands of small cells (cellular network) for transmission. In addition, in order to reduce the latency of 5G, multi-access edge computing technology (MEC) has also emerged.
