Gli ingegneri del Laboratorio di Intelligenza Artificiale del Massachusetts Institute of Technology (MIT CSAIL) hanno sviluppato una «superficie intelligente» chiamata RFocus, che «pu\u00f2 funzionare come uno specchio o una lente» per focalizzare i segnali radio sui dispositivi desiderati.<\/p>\n

\"MIT<\/p>\n

Attualmente esiste un problema significativo nell'assicurare una connessione wireless stabile per dispositivi miniaturizzati, all'interno dei quali c'\u00e8 praticamente poco spazio per collocare le antenne. A risolvere questo problema pu\u00f2 essere la «superficie intelligente» RFocus, la cui versione sperimentale aumenta la potenza media del segnale di quasi 10 volte, raddoppiando contemporaneamente la larghezza di banda del canale.  <\/p>\n

Invece di utilizzare diverse antenne monolitiche, gli sviluppatori di RFocus hanno impiegato pi\u00f9 di 3000 antenne miniaturizzate, integrandole con il software appropriato, riuscendo cos\u00ec a ottenere un notevole incremento della potenza del segnale. In altre parole, RFocus funziona come un controllore della direzionalit\u00e0 del fascio, posizionato davanti ai dispositivi client finali. Gli autori del progetto ritengono che un tale array sar\u00e0 relativamente economico da produrre, poich\u00e9 il costo di ogni antenna miniaturizzata \u00e8 di appena qualche centesimo. Si fa notare che il prototipo di RFocus consuma meno energia rispetto ai sistemi tradizionali. Questo abbattimento del consumo energetico \u00e8 stato possibile grazie all'esclusione degli amplificatori di segnale dal sistema.<\/p>\n

\n\"MIT<\/p>\n

Gli autori del progetto credono che il sistema da loro creato, presentato sotto forma di \u00absfondi sottili\u00bb, possa trovare ampio utilizzo, incluso nel campo dell'Internet delle cose (IoT) e nelle reti di quinta generazione (5G), fornendo un potenziamento del segnale trasmesso ai dispositivi finali degli utenti. Non \u00e8 ancora chiaro quando gli sviluppatori prevedano di lanciare la loro creazione sul mercato commerciale. Fino a quel momento dovranno perfezionare il design del prodotto finale, rendendo il sistema il pi\u00f9 efficace e attraente possibile per i potenziali acquirenti.<\/p>\n
