See in this article how the shutdown of the analog signal, and the availability of its frequency channels, will be used in the advancement of 4G and 5G technology in Brazil.
The analog TV signal has been gradually switched off in cities since 2016, the year scheduled for the complete shutdown of analog transmission in Brazil. The forecast was postponed to 2018, and later to 2023. According to the Ministry of Communications (MCom), the goal is to bring the Digital TV signal, by 2022, to 1,638 Brazilian cities, which currently only have analog television.
The Digitaliza Brasil project aims to bring the digital TV signal to all of Brazil, so that in 2023, when there is a total shutdown, no one will be left without a television signal , a means of communication used usa phone number listsby more than 90% of the population. The project intends to install equipment in municipalities, and will give authorization to broadcasters that wish to make the transition, as long as they express interest.
The signal digitization process is simple and covers both new and old devices, requiring only the inclusion of an antenna. For older devices that do not have digital reception integrated into the TV, a signal converter device is required, and the Digitaliza Brasil program provides for the distribution of these devices to low-income families.

In an interview, Professor Eduardo Peixoto, from the Department of Electrical Energy at the University of Brasília (UnB), explains the advantages of replacing the analog signal with a digital one:
“Improved image quality, access to a more stable signal with less interference, and access to a greater number of channels. Indirect advantages appear as services that can be provided when the analog signal is switched off. In Brazil, in many cities, the 4G mobile phone signal uses frequency channels that were made available after the analog signal was switched off.”
According to the professor, in some countries the 4G and 5G signal were allocated to vacant channels after the analog signal was switched off, and when it is made available in Brazil, 5G technology will also be able to take advantage of the vacant space on the analog frequency.
