Telecommunications networks have been with us for a long time, and every year new technologies emerge that make our day-to-day life easier. With the arrival of the third generation, we obtained an improvement in the internet service in the sense that we could obtain higher speeds. This gave way to a very wide path to continue with the networks. Thus comes the fourth generation network with the intention of being compatible, interoperable and convergent for all telecommunications services, also, with a high internet speed, greater capacity, improvements in its antennas and signal quality. One of its problems remains the unpredictability of its service as it is not entirely stable in its speed because it depends on the region and the users connected to the network. This article helps to know the characteristics of the third and fourth generation mobile networks, their evolution over time and talks about the changes and innovations that will bring the fifth generation mobile network (5G).
