Revolucion\u0101rs bezvadu datu p\u0101rraides risin\u0101jums<\/p>\n
P\u0113tnieki no Kalifornijas Universit\u0101tes \u012arvain\u0101 (UC Irvine) ir izstr\u0101d\u0101ju\u0161i eksperiment\u0101lu bezvadu trans\u012bveri, kas darbojas ap 140 GHz frekvenc\u0113 un sp\u0113j sasniegt datu p\u0101rraides \u0101trumu l\u012bdz pat 120 gigabitiem sekund\u0113 (Gb\/s). Tas ir aptuveni 15 gigabaitu (GB) datu sekund\u0113, kas ir 24 reizes \u0101tr\u0101k nek\u0101 teor\u0113tiskais 5G maksim\u0101lais \u0101trums un iev\u0113rojami p\u0101rsniedz pa\u0161reiz\u0113j\u0101s komerci\u0101l\u0101s bezvadu tehnolo\u0123ijas. Sal\u012bdzin\u0101jumam, Wi-Fi 7 maksim\u0101lais \u0101trums ir ap 30 Gb\/s, bet 5G mmWave \u2013 l\u012bdz 5 Gb\/s.<\/p>\n

Zin\u0101tnieki savus atkl\u0101jumus public\u0113ju\u0161i divos rakstos IEEE \u017eurn\u0101l\u0101 Journal of Solid-State Circuits, aprakstot \u00abbits-l\u012bdz-antenas\u00bb arhitekt\u016bru raid\u012bt\u0101jam un \u00abantenas-l\u012bdz-biti\u00bb arhitekt\u016bru uztv\u0113r\u0113jam. \u0160\u012b pieeja \u013cauj tie\u0161i str\u0101d\u0101t ar analogajiem sign\u0101liem, apiet tradicion\u0101lo digit\u0101lo p\u0101rveido\u0161anu.<\/p>\n

Lai risin\u0101tu \u0161o probl\u0113mu, komanda nevis izmantoja vienu jaud\u012bgu DAC, bet gan tr\u012bs sinhroniz\u0113tus apak\u0161raid\u012bt\u0101jus.
