Ngokuqaliswa kwe-5G kwezentengiselwano, izingxoxo ngakho beziningi muva nje. Labo abajwayelene ne-5G bayazi ukuthi amanethiwekhi e-5G asebenza kakhulu kuma-frequency band amabili: amagagasi angaphansi kwe-6GHz kanye nama-millimeter (ama-Millimeter Waves). Eqinisweni, amanethiwekhi ethu amanje e-LTE asekelwe kuma-sub-6GHz, kanti ubuchwepheshe bamagagasi e-millimeter buyisihluthulelo sokuvula amandla aphelele enkathi ye-5G ecatshangelwayo. Ngeshwa, naphezu kwentuthuko yamashumi eminyaka kwezokuxhumana kweselula, amagagasi e-millimeter akakangeni ngempela ezimpilweni zabantu ngenxa yezizathu ezahlukahlukene.
Kodwa-ke, ochwepheshe eNgqungqutheleni ye-5G yaseBrooklyn ngo-Ephreli basikisela ukuthi amagagasi e-terahertz (amagagasi e-Terahertz) angase alungise ukushiyeka kwamagagasi e-millimeter futhi asheshise ukufezwa kwe-6G/7G. Amagagasi e-Terahertz anamandla angenamkhawulo.
Ngo-Ephreli, iNgqungquthela yesi-6 yeBrooklyn 5G yabanjwa njengoba kwakuhleliwe, ihlanganisa izihloko ezifana nokusetshenziswa kwe-5G, izifundo ezifundiwe, kanye nombono wokuthuthukiswa kwe-5G. Ngaphezu kwalokho, uSolwazi uGerhard Fettweis waseDresden University of Technology kanye noTed Rappaport, umsunguli we-NYU Wireless, baxoxe ngamandla amagagasi e-terahertz esicongweni.
Ochwepheshe ababili bathi abacwaningi sebeqalile ukutadisha amagagasi e-terahertz, futhi amaza awo azoba yingxenye ebalulekile yesizukulwane esilandelayo sobuchwepheshe obungenantambo. Ngesikhathi ekhuluma engqungqutheleni, uFettweis ubuyekeze izizukulwane zangaphambilini zobuchwepheshe bokuxhumana ngeselula futhi waxoxa ngamathuba amagagasi e-terahertz ekubhekaneni nemikhawulo ye-5G. Uveze ukuthi singena enkathini ye-5G, ebalulekile ekusetshenzisweni kobuchwepheshe obufana ne-Internet of Things (IoT) kanye ne-augmented reality/virtual reality (AR/VR). Nakuba i-6G ifana kakhulu nezizukulwane zangaphambilini, izobhekana nokushiyeka okuningi.
Ngakho-ke, iyini ngempela amagagasi e-terahertz, ochwepheshe abawahlonipha kangaka? Amagagasi e-Terahertz aphakanyiswa yi-United States ngo-2004 futhi abhalwe njengenye ye-“Top Ten Technologies That Will Change the World.” Ubude bawo busukela kuma-micrometer angu-3 (μm) kuya ku-1000 μm, kanti imvamisa yawo isukela ku-300 GHz kuya ku-3 terahertz (THz), ephakeme kunemvamisa ephezulu esetshenziswa ku-5G, okungu-300 GHz yamagagasi e-millimeter.
Kusukela kumdwebo ongenhla, kungabonakala ukuthi amagagasi e-terahertz aphakathi kwamagagasi omsakazo namagagasi okukhanya, okuwanikeza izici ezihlukile kwamanye amagagasi kagesi ngezinga elithile. Ngamanye amazwi, amagagasi e-terahertz ahlanganisa izinzuzo zokuxhumana nge-microwave kanye nokuxhumana okukhanya, njengezinga eliphezulu lokudlulisa, umthamo omkhulu, ukuqondiswa okuqinile, ukuphepha okuphezulu, kanye nokungena okunamandla.
Ngokwethiyori, emkhakheni wokuxhumana, uma imvamisa iphakeme, kulapho amandla okuxhumana eba makhulu khona. Imvamisa yamagagasi e-terahertz iphakeme ngama-oda angu-1 kuya kwangu-4 kunama-microwave asetshenziswa njengamanje, futhi inganikeza amazinga okudlulisa angenantambo ama-microwave angenakuwafinyelela. Ngakho-ke, ingaxazulula inkinga yokudluliswa kolwazi okunqunyelwe yi-bandwidth futhi ihlangabezane nezidingo ze-bandwidth zabasebenzisi.
Amagagasi e-Terahertz kulindeleke ukuthi asetshenziswe kwezobuchwepheshe bokuxhumana eminyakeni eyishumi ezayo. Nakuba ochwepheshe abaningi bekholelwa ukuthi amagagasi e-terahertz azoguqula imboni yokuxhumana, akukacaci ukuthi yiziphi izinkinga ezithile angazixazulula. Lokhu kungenxa yokuthi opharetha beselula emhlabeni wonke basanda kwethula amanethiwekhi abo e-5G, futhi kuzothatha isikhathi ukuhlonza amaphutha.
Kodwa-ke, izici zomzimba zamagagasi e-terahertz sezivele zigqamise izinzuzo zawo. Isibonelo, amagagasi e-terahertz anama-wavelength amafushane kanye nama-frequency aphezulu kunamagagasi e-millimeter. Lokhu kusho ukuthi amagagasi e-terahertz angadlulisela idatha ngokushesha nangobuningi obukhulu. Ngakho-ke, ukwethula amagagasi e-terahertz kumanethiwekhi eselula kungabhekana nokushoda kwe-5G ekudlulisweni kwedatha kanye nokubambezeleka.
UFettweis uphinde wethula imiphumela yokuhlolwa ngesikhathi senkulumo yakhe, ekhombisa ukuthi ijubane lokudlulisa amagagasi e-terahertz liyi-1 terabyte ngomzuzwana (TB/s) ngaphakathi kwamamitha angu-20. Nakuba lokhu kusebenza kungavelele kakhulu, uTed Rappaport usakholelwa ngokuqinile ukuthi amagagasi e-terahertz ayisisekelo se-6G kanye ne-7G yesikhathi esizayo.
Njengophayona emkhakheni wocwaningo lwamagagasi e-millimeter, uRappaport ubonakalise indima yamagagasi e-millimeter kumanethiwekhi e-5G. Uvumile ukuthi ngenxa yokuvama kwamagagasi e-terahertz kanye nokuthuthukiswa kobuchwepheshe bamanje beselula, abantu bazobona maduze ama-smartphone anamakhono okusebenzisa ikhompyutha afana nobuchopho bomuntu maduze nje.
Yiqiniso, ngezinga elithile, konke lokhu kuqagela kakhulu. Kodwa uma ukuthambekela kwentuthuko kuqhubeka njengoba kunjalo njengamanje, singalindela ukubona opharetha beselula besebenzisa amaza e-terahertz kubuchwepheshe bokuxhumana eminyakeni eyishumi ezayo.
