In the Alt Penedès, Anoia, Baix Llobregat, Barcelonès, Garraf, Maresme, Vallès Occidental and Vallès Oriental you will not have to do anything.
With the deployment of 5G technology, TV DTT channels will be re-tuned. The 5G needs more space on the side of DTT that many television channels now occupy so that from now on this new communication technology will occupy it. But it is not necessary for everyone to do it, since most of the demarcation of Barcelona is exempt from ressintonització.
The development of future 5G technology networks affects all channels. Since November 14, the emission frequencies in some areas have begun to change.
The change affects the regions of Girona, Lleida and Tarragona, and will be done progressively and for a few months. This change does not affect the channels of the Corporation in the regions of Barcelona and, therefore, the spectators of this demarcation will not have to do anything, specifically in the regions of Alt Penedès, Anoia, Baix Llobregat, Barcelonès, Garraf, Maresme , Vallès Occidental and Vallès Oriental. You can consult the regions affected by the ressintonització and television channels that change frequency on the Generalitat website.
Those who live in a single-family home with an individual antenna should only reset the channels using the TV remote control.
In neighboring communities that have a collective antenna, it will be necessary to notify an approved installation company in order to adapt the antenna; Once adapted, each neighbor in your home must resitonize the channels.
