There are currently several projects and technologies focusing on smart cities, with the aim of
expanding the integration between public and private institutions, solving or minimizing basic
and complex problems of our daily lives. Applications aimed at safety, education, health,
energy, environment, mobility and others. To make it possible to implement solutions for
these areas, it is necessary that in the background, there is a future-proof telecommunications
infrastructure with the convergence of different services over the same network. This work
aims to present the main technologies of hybrid access network (Optical-wireless), being this,
the topology most used in smart cities, due to the high capacity of bandwidth and speed of the
optical fiber and the flexibility and ubiquity of the wireless network. Also addressing, in a
more superficial way, various access network technologies, FTTX and wireless variations,
multiple access, smart cities, AON and PON networks and passive and active equipment,
which make up a telecommunications infrastructure.
