At the opening of Academic Year 2019-2020, the academician Miguel Angel Lagunas began with a brief introduction on digitisation and the first steps in the limits of transmission speed, making a short journey through the five generations from the first to the fifth. The deployment of this fifth generation is taking place now. Before going through that journey, he introduced two elements that were considered essential in the evolution of radio generations: the layered structure and information theory.

5G inverts the natural or temporary order of things, based on two singularities of great importance in this generation compared with previous ones. The first is that 5G is not a new generation mobile radio, but a new communications infrastructure that also involve cable, fibre and satellite technologies. This leads to a greater ability to make a big leap in supported applications and scenarios. These are the two reasons why this odd generation seems very different and certainly fascinating from an engineering perspective.
