The first section of this article introduces the problem of usage norms that are detrimental to Catalan in interpersonal relations between Castilian and Catalan speakers. It goes on to describe the main campaigns promoting the use of Catalan in these intergroup relations, from El català és cosa de tots (Catalonia, 1981) to Integra'm, Integra'l (Minorca, 2005(Minorca, -2006, including on the way other Catalan, Balearic and Valencian campaigns. To conclude, it points to, on the one hand, the limits of these campaigns within a liberal democratic framework and, on the other, the difficulties in assessing their effects on everyday competences, usages and attitudes.

Multi-functional wireless networks are rapidly evolving and aspire to become a promising attribute of the upcoming 6G networks. Enabling multiple simultaneous networking functions with a single radio fosters the development of more integrated and simpler equipment, overcoming design and technology barriers inherited from radio systems of the past. We are seeing numerous trends exploiting these features in newly designed radios, such as those operating on the mmWave band. In this article, however, we carefully analyze the challenges and opportunities for multi-functional wireless networks in UHF bands, advocating the reuse of existing infrastructures and technologies, and exploring the possibilities of expanding their functionality without requiring architectural changes. We believe that both modern and legacy technologies can be turned into multi-functional systems if the right scientific and technological challenges are properly addressed. This transformation can foster the development of new applications and extend the useful life of these systems, contributing to a more sustainable digitization by delaying equipment obsolescence.
