Ngokusho kwe-Nikkei News, i-NTT kanye ne-KDDI yaseJapan bahlela ukubambisana ocwaningweni nasekuthuthukisweni kwesizukulwane esisha sobuchwepheshe bokuxhumana nge-optical, futhi bathuthukise ubuchwepheshe obuyisisekelo bamanethiwekhi okuxhumana okonga amandla kakhulu asebenzisa izimpawu zokudlulisa nge-optical kusuka emigqeni yokuxhumana kuya kumaseva kanye nama-semiconductor.
Lezi zinkampani ezimbili zizosayina isivumelwano maduze nje, zisebenzisa i-IOWN, ipulatifomu yokuxhumana ngobuchwepheshe be-optical eyakhiwe ngokuzimela yi-NTT, njengesisekelo sokubambisana. Ngokusebenzisa ubuchwepheshe be-"photoelectric fusion" obuthuthukiswa yi-NTT, ipulatifomu ingafeza konke ukucutshungulwa kwesignali kwamaseva ngendlela yokukhanya, ilahle ukudluliswa kwesignali kagesi kwangaphambilini eziteshini eziyisisekelo kanye nemishini yeseva, futhi inciphise kakhulu ukusetshenziswa kwamandla okudlulisa. Lobu buchwepheshe buqinisekisa nokusebenza kahle kakhulu kokudlulisa idatha ngenkathi kunciphisa ukusetshenziswa kwamandla. Amandla okudlulisa e-fiber ngayinye ye-optical azokhushulwa abe izikhathi ezingu-125 kuneyokuqala, futhi isikhathi sokulibaziseka sizofinyezwa kakhulu.
Njengamanje, ukutshalwa kwezimali kumaphrojekthi nemishini ehlobene ne-IOWN sekufinyelele kumadola aseMelika ayizigidi ezingu-490. Ngokusekelwa kobuchwepheshe bokudlulisa ukukhanya be-KDDI, isivinini socwaningo nentuthuko sizosheshiswa kakhulu, futhi kulindeleke ukuthi sithengiswe kancane kancane ngemva kuka-2025.
I-NTT ithe inkampani kanye ne-KDDI bazolwela ukuba yingcweti kwezobuchwepheshe obuyisisekelo phakathi no-2024, banciphise ukusetshenziswa kwamandla kwamanethiwekhi olwazi nokuxhumana okuhlanganisa nezikhungo zedatha kube yi-1% ngemuva kuka-2030, futhi balwele ukuthatha isinyathelo sokwakha amazinga e-6G.
Ngesikhathi esifanayo, lezi zinkampani ezimbili zinethemba lokubambisana nezinye izinkampani zokuxhumana, imishini, kanye nabakhiqizi be-semiconductor emhlabeni wonke ukuze benze intuthuko ehlangene, basebenzisane ukuxazulula inkinga yokusetshenziswa kwamandla aphezulu ezikhungweni zedatha zesikhathi esizayo, futhi bakhuthaze ukuthuthukiswa kobuchwepheshe bokuxhumana besizukulwane esilandelayo.
Eqinisweni, kusukela ngo-Ephreli 2021, i-NTT yayinomqondo wokufeza ukwakheka kwenkampani kwe-6G ngobuchwepheshe bokuxhumana be-optical. Ngaleso sikhathi, inkampani yabambisana neFujitsu nge-NTT Electronics Corporation engaphansi kwayo. La maqembu amabili agxile futhi epulatifomu ye-IOWN ukuze inikeze isisekelo sokuxhumana sesizukulwane esilandelayo ngokuhlanganisa zonke izingqalasizinda zenethiwekhi ye-photonic kufaka phakathi i-silicon photonics, i-edge computing, kanye ne-wireless distributed computing.
Ngaphezu kwalokho, i-NTT ibambisana ne-NEC, i-Nokia, i-Sony, njll. ukuze yenze ukubambisana kwesilingo se-6G futhi ilwele ukuhlinzeka ngeqoqo lokuqala lezinsizakalo zezentengiselwano ngaphambi kuka-2030. Ukuhlolwa kwangaphakathi kuzoqala ngaphambi kokuphela kukaMashi 2023. Ngaleso sikhathi, i-6G ingase ikwazi ukunikeza amandla aphindwe kayikhulu kune-5G, isekele amadivayisi ayizigidi eziyi-10 ngekhilomitha lesikwele, futhi ikwazi ukumbozwa kwezimpawu ze-3D emhlabeni, olwandle, nasemoyeni. Imiphumela yokuhlolwa izophinde iqhathaniswe nocwaningo lomhlaba wonke. Izinhlangano, izingqungquthela, kanye nezinhlangano ezijwayelekile ziyabelana.
Njengamanje, i-6G ibhekwa “njengethuba lama-trillion dollar” embonini yeselula. Ngesitatimende soMnyango Wezimboni Nobuchwepheshe Bolwazi mayelana nokusheshisa ucwaningo nentuthuko ye-6G, iNgqungquthela Yobuchwepheshe Be-6G Yomhlaba Wonke, kanye ne-Barcelona Mobile World Congress, i-6G isibe yindawo ebaluleke kakhulu emakethe yezokuxhumana.
Amazwe nezikhungo ezahlukahlukene nazo zimemezele ucwaningo oluhlobene ne-6G eminyakeni eminingi edlule, zincintisana ngesikhundla esiphambili kuthrekhi ye-6G.
Ngo-2019, iNyuvesi yase-Oulu eFinland yakhipha iphepha elimhlophe lokuqala emhlabeni le-6G, elavula ngokusemthethweni isethulo socwaningo oluhlobene ne-6G. NgoMashi 2019, i-US Federal Communications Commission yahola ekumemezeleni ukuthuthukiswa kwebhendi yemvamisa ye-terahertz yezivivinyo zobuchwepheshe be-6G. Ngo-Okthoba wonyaka olandelayo, i-US Telecom Industry Solutions Alliance yasungula i-Next G Alliance, inethemba lokukhuthaza ucwaningo lwelungelo lobunikazi lobuchwepheshe be-6G nokusungula i-United States kubuchwepheshe be-6G.
I-European Union izokwethula iphrojekthi yocwaningo lwe-6G i-Hexa-X ngo-2021, ihlanganise i-Nokia, i-Ericsson, nezinye izinkampani ukuze zikhuthaze ucwaningo nentuthuko ye-6G ngokubambisana. INingizimu Korea yasungula ithimba locwaningo lwe-6G kusukela ngo-Ephreli 2019, imemezela imizamo yokucwaninga nokusebenzisa ubuchwepheshe bokuxhumana besizukulwane esisha.
