Ngokwethulwa kwezentengiso kwe-5G, izingxoxo ngayo beziningi muva nje. Labo abajwayele i-5G bayazi ukuthi amanethiwekhi e-5G ngokuyinhloko asebenza kumabhendi amabili okuvama: i-sub-6GHz namaza amamilimitha (Millimeter Waves). Eqinisweni, amanethiwekhi ethu amanje e-LTE wonke asekelwe ku-sub-6GHz, kuyilapho ubuchwepheshe be-millimeter wave buyisihluthulelo sokuvula amandla aphelele enkathi ye-5G ecatshangwayo. Ngeshwa, naphezu kwamashumi eminyaka yentuthuko kwezokuxhumana ngeselula, amaza amamilimitha awakangeni ngempela ezimpilweni zabantu ngenxa yezizathu ezahlukahlukene.
Kodwa-ke, ochwepheshe eNgqungqutheleni ye-5G yaseBrooklyn ngo-Ephreli baphakamise ukuthi amagagasi e-terahertz (Amagagasi eTerahertz) angase anxephezele ukushiyeka kwamagagasi amamilimitha futhi asheshise ukugcwaliseka kwe-6G/7G. Amagagasi eTerahertz anamandla angenamkhawulo.
Ngo-Ephreli, iNgqungquthela yesi-6 yaseBrooklyn 5G yabanjwa njengoba kwakuhleliwe, ihlanganisa izihloko ezinjengokuthunyelwa kwe-5G, izifundo ezifundiwe, kanye nombono wokuthuthukiswa kwe-5G. Ukwengeza, uProfesa Gerhard Fettweis waseDresden University of Technology kanye no-Ted Rappaport, umsunguli we-NYU Wireless, baxoxisane ngamagagasi e-terahertz engqungqutheleni.
Labo chwepheshe ababili bathi abacwaningi sebeqalile ukufunda amaza e-terahertz, futhi amaza awo azoba yingxenye ebalulekile yesizukulwane esilandelayo sobuchwepheshe obungenawaya. Phakathi nenkulumo yakhe engqungqutheleni, u-Fettweis ubuyekeze izizukulwane ezedlule zobuchwepheshe bokuxhumana kweselula futhi waxoxa ngamagagasi e-terahertz ekubhekaneni nokulinganiselwa kwe-5G. Uveze ukuthi singena enkathini ye-5G, okubalulekile ekusetshenzisweni kobuchwepheshe obufana ne-Inthanethi Yezinto (IoT) kanye ne-augmented reality/virtual reality (AR/VR). Nakuba i-6G yabelana ngokufana okuningi nezizukulwane ezedlule, izophinde ibhekane nokushiyeka okuningi.
Ngakho, ayini ngempela amagagasi e-terahertz, ochwepheshe abawazisa kangaka? Amagagasi eTerahertz ahlongozwa yi-United States ngo-2004 futhi afakwa ohlwini “Lobuchwephesha Beshumi Eliphezulu Oluzoshintsha Umhlaba.” Ubude begagasi bawo busuka ku-3 micrometers (μm) kuye ku-1000 μm, futhi imvamisa yawo isukela ku-300 GHz ukuya ku-3 terahertz (THz), ephakeme kunefrikhwensi ephezulu kakhulu esetshenziswa ku-5G, okungama-300 GHz kumaza amamilimitha.
Kusukela kumdwebo ongenhla, kungabonakala ukuthi amaza e-terahertz aphakathi kwamagagasi omsakazo namagagasi okubona, okuwanika izici ezihlukile kwamanye amaza kagesi ngokwezinga elithile. Ngamanye amazwi, amaza e-terahertz ahlanganisa izinzuzo zokuxhumana nge-microwave kanye nokuxhumana okubonakalayo, okufana namazinga aphezulu okudlulisela, umthamo omkhulu, ukuqondiswa okuqinile, ukuphepha okuphezulu, nokungena okuqinile.
Ngokwethiyori, emkhakheni wezokuxhumana, lapho imvamisa ephezulu, amandla okuxhumana ayanda. Imvamisa yamagagasi e-terahertz ingu-1 kuya ku-4 oda wobukhulu ngaphezu kwama-microwave asetshenziswayo njengamanje, futhi ingahlinzeka ngamanani okudlulisela okungenawaya ama-microwave angakwazi ukuwafinyelela. Ngakho-ke, ingaxazulula inkinga yokudluliswa kolwazi okukhawulelwe umkhawulokudonsa futhi ihlangabezane nezidingo zomkhawulokudonsa wabasebenzisi.
Amagagasi eTerahertz kulindeleke ukuthi asetshenziswe kwezobuchwepheshe bezokuxhumana phakathi neminyaka eyishumi ezayo. Nakuba ochwepheshe abaningi bekholelwa ukuthi amagagasi e-terahertz azoguqula imboni yezokuxhumana, namanje akukacaci ukuthi yiziphi izinkinga ezithile abangabhekana nazo. Lokhu kungenxa yokuthi opharetha beselula emhlabeni wonke basanda kwethula amanethiwekhi abo e-5G, futhi kuzothatha isikhathi ukukhomba amaphutha.
Kodwa-ke, izici zomzimba zamagagasi e-terahertz sezivele zigqamisile izinzuzo zabo. Isibonelo, amagagasi e-terahertz anobude obufushane beza beza namaza aphezulu kunamaza amamilimitha. Lokhu kusho ukuthi amagagasi e-terahertz angadlulisela idatha ngokushesha nangenani elikhulu. Ngakho-ke, ukwethula amagagasi e-terahertz kumanethiwekhi eselula kungase kubhekane nokushiyeka kwe-5G ekusetshenzisweni kwedatha nokubambezeleka.
U-Fettweis ubuye wethula imiphumela yokuhlolwa phakathi nenkulumo yakhe, ebonisa ukuthi isivinini sokudluliselwa kwamagagasi e-terahertz singu-1 terabyte ngomzuzwana (TB/s) phakathi kwamamitha angu-20. Nakuba lokhu kusebenza kungavelele kakhulu, u-Ted Rappaport usakholelwa ngokuqinile ukuthi amaza e-terahertz ayisisekelo se-6G yesikhathi esizayo kanye ne-7G.
Njengengqalabutho emkhakheni wocwaningo lwamagagasi emilimitha, iRappaport ifakazele indima yamaza amamilimitha kumanethiwekhi e-5G. Uvumile ukuthi ngenxa yemvamisa yamagagasi e-terahertz kanye nokuthuthukiswa kobuchwepheshe bamanje bamaselula, abantu maduzane bazobona ama-smartphones anamandla okwenza ikhompuyutha afana nobuchopho bomuntu esikhathini esizayo esiseduze.
Yiqiniso, ngezinga elithile, konke lokhu kuwukuqagela kakhulu. Kodwa uma intuthuko iqhubeka njengoba injalo njengamanje, singalindela ukubona opharetha beselula besebenzisa amaza e-terahertz kubuchwepheshe bezokuxhumana phakathi neminyaka eyishumi ezayo.
