Ingeni\u00f8rer fra Massachusetts Institute of Technology's Artificial Intelligence Laboratory (MIT CSAIL) har udviklet en \"smart overflade\" kaldet RFocus, som \"kan fungere som et spejl eller linse\" til at fokusere radiosignaler p\u00e5 de \u00f8nskede enheder.<\/p>\n

\"MIT-ingeni\u00f8rer<\/p>\n

I \u00f8jeblikket eksisterer der et specifikt problem med at sikre en stabil tr\u00e5dl\u00f8s forbindelse mellem miniatureenheder, hvor der praktisk talt ikke er plads til at placere antenner. Dette kan rettes med den \"smarte overflade\" RFocus, hvis eksperimentelle version \u00f8ger den gennemsnitlige signalstyrke n\u00e6sten ti gange, samtidig med at b\u00e5ndbredden fordobles.  <\/p>\n

I stedet for flere monolitiske antenner har udviklerne af RFocus anvendt over 3000 miniatureantenner, der supplerer med det relevante software, hvilket har gjort det muligt at opn\u00e5 en s\u00e5 signifikant stigning i signalstyrken. Med andre ord fungerer RFocus som en str\u00e5leorienteringskontroller, der placeres foran de endelige klientenheder. Projektets forfattere mener, at en s\u00e5dan masse vil v\u00e6re relativt billig at producere, da omkostningerne ved hver miniatureantenne kun er et par cent. Det bem\u00e6rkes, at prototypen af RFocus forbruger mindre energi sammenlignet med traditionelle systemer. Dette lavere energiforbrug er opn\u00e5et ved at udelade signalforst\u00e6rkere fra systemet.<\/p>\n

\n\"MIT-ingeni\u00f8rer<\/p>\n

Forfatterne af projektet mener, at det system, de har skabt, som udgives som \"tynde tapeter\", kan finde bred anvendelse, is\u00e6r inden for Internet of Things (IoT) og femte generations kommunikationsnetv\u00e6rk (5G), ved at sikre forst\u00e6rkning af signalet, der overf\u00f8res til de endelige brugerudstyr. Hvorn\u00e5r udviklerne planl\u00e6gger at lancere deres opfindelse p\u00e5 det kommercielle marked, er endnu uklart. Inden da skal de finpudse designet af det endelige produkt for at g\u00f8re systemet s\u00e5 effektivt og tiltalende som muligt for potentielle k\u00f8bere.<\/p>\n
