Despite the fact that DAB+ signals already reach 99 % of the population in Switzerland, as required by the Federal Office of Communications (OFCOM), the public broadcaster has further expanded the digital network in Italian and French-speaking Switzerland. Between 2020 and 2021, ten new transmitters were activated and twelve others were optimized. Improvements were made in the cantons of Jura, in the northwest of the country, and Ticino, located almost entirely south of the Alps, where the network was further expanded at the beginning of 2021 with the activation of the installation in Cardada. In Switzerland, the digital signal is also broadcast in tunnels longer than 300 meters: the list of the 193 road tunnels covered by DAB+ signals can be consulted on broadcast.ch.
