Ngokusungulwa kwe-5G kurhwebo, iingxoxo ngayo bezininzi kutshanje. Abo baqhelene ne-5G bayazi ukuba iinethiwekhi ze-5G zisebenza ikakhulu kwiibhendi ezimbini zefrikhwensi: ii-sub-6GHz kunye namaza e-millimeter (ii-Millimeter Waves). Enyanisweni, iinethiwekhi zethu zangoku ze-LTE zonke zisekelwe kwi-sub-6GHz, ngelixa iteknoloji yamaza e-millimeter isitshixo sokuvula amandla apheleleyo exesha le-5G elicingelwayo. Ngelishwa, nangona kudlule amashumi eminyaka yokuqhubela phambili kunxibelelwano lweselula, amaza e-millimeter akakangeni ngokwenene ebomini babantu ngenxa yezizathu ezahlukeneyo.
Nangona kunjalo, iingcali kwiNgqungquthela yeBrooklyn 5G ngo-Epreli zicebise ukuba amaza e-terahertz (amaza e-Terahertz) anokulungisa ukusilela kwamaza e-millimeter aze akhawulezise ukuphunyezwa kwe-6G/7G. Amaza e-Terahertz anamandla angenamkhawulo.
Ngo-Epreli, iNgqungquthela yesi-6 yeBrooklyn 5G yabanjwa njengoko bekucwangcisiwe, igubungela izihloko ezinje ngokusasazwa kwe-5G, izifundo ezifundiweyo, kunye nombono wophuhliso lwe-5G. Ukongeza, uNjingalwazi uGerhard Fettweis waseDresden University of Technology kunye noTed Rappaport, umseki we-NYU Wireless, baxoxe ngamandla amaza e-terahertz kwingqungquthela.
Ezi ngcali zimbini zithi abaphandi sele beqalile ukufunda amaza e-terahertz, kwaye amaza awo aya kuba yinxalenye ebalulekileyo yesizukulwana esilandelayo setekhnoloji engenazingcingo. Ngexesha lentetho yakhe kwingqungquthela, uFettweis uphonononge izizukulwana zangaphambili zetekhnoloji yonxibelelwano lweselula waza waxoxa ngamandla amaza e-terahertz ekusombululeni imida ye-5G. Ubonise ukuba singena kwixesha le-5G, elibalulekileyo ekusetyenzisweni kwetekhnoloji efana ne-Intanethi yezinto (IoT) kunye ne-augmented reality/virtual reality (AR/VR). Nangona i-6G ifana kakhulu nezizukulwana zangaphambili, iya kujongana neentsilelo ezininzi.
Ngoko ke, yintoni kanye kanye amaza e-terahertz, ahlonitshwa ziingcali kangaka? Amaza e-Terahertz acetywa yi-United States ngo-2004 kwaye adweliswe njengenye ye "Top Ten Technologies That Will Chang the World." Ububanzi bawo buqala kwi-3 micrometers (μm) ukuya kwi-1000 μm, kwaye ubuninzi bawo buqala kwi-300 GHz ukuya kwi-3 terahertz (THz), iphezulu kuneyona frequency iphezulu esetyenziswa kwi-5G, eyi-300 GHz yamaza e-millimeter.
Ukusuka kumzobo ongentla, kunokubonwa ukuba amaza e-terahertz aphakathi kwamaza erediyo namaza e-optical, nto leyo ewanika iimpawu ezahlukileyo kwamanye amaza e-electromagnetic ukuya kwinqanaba elithile. Ngamanye amazwi, amaza e-terahertz adibanisa iingenelo zonxibelelwano lwe-microwave kunye nonxibelelwano lwe-optical, ezifana namazinga aphezulu okudlulisela, amandla amakhulu, indlela enamandla, ukhuseleko oluphezulu, kunye nokungena ngamandla.
Ngokwethiyori, kwicandelo lonxibelelwano, okukhona i-frequency iphezulu, kokukhona amandla onxibelelwano aphezulu. I-frequency yamaza e-terahertz iphezulu nge-1 ukuya kwi-4 orders zobukhulu kunee-microwave ezisetyenziswayo ngoku, kwaye inokubonelela ngamazinga okudlulisa ngaphandle kwentambo angenakufikelelwa zii-microwave. Ke ngoko, inokusombulula ingxaki yokudluliselwa kolwazi oluthintelwe yi-bandwidth kwaye ihlangabezane neemfuno ze-bandwidth zabasebenzisi.
Kulindeleke ukuba amaza eTerahertz asetyenziswe kubuchwepheshe bonxibelelwano kwiminyaka elishumi ezayo. Nangona iingcali ezininzi zikholelwa ukuba amaza eTerahertz aza kutshintsha ishishini lonxibelelwano, akukacaci ukuba zeziphi iziphene ezithile anokujongana nazo. Oku kungenxa yokuba abaqhubi beefowuni kwihlabathi liphela basandul’ ukuqalisa iinethiwekhi zabo ze-5G, kwaye kuya kuthatha ixesha ukuchonga iziphene.
Nangona kunjalo, iimpawu zomzimba zamaza e-terahertz sele zibonakalise iingenelo zawo. Umzekelo, amaza e-terahertz anee-wavelengths ezimfutshane kunye nee-frequency eziphezulu kunee-millimeter waves. Oku kuthetha ukuba amaza e-terahertz anokudlulisa idatha ngokukhawuleza nangobuninzi obukhulu. Ke ngoko, ukungenisa amaza e-terahertz kwiinethiwekhi eziphathwayo kunokujongana nokusilela kwe-5G kwi-data throughput kunye ne-latency.
UFettweis ukwaveze iziphumo zovavanyo ngexesha lentetho yakhe, ebonisa ukuba isantya sokudluliselwa kwamaza e-terahertz yi-1 terabyte ngomzuzwana (TB/s) ngaphakathi kweemitha ezingama-20. Nangona le ntsebenzo ingabonakali kangako, uTed Rappaport usakholelwa ngokuqinileyo ukuba amaza e-terahertz sisiseko se-6G kunye ne-7G yexesha elizayo.
Njengovulindlela kwicandelo lophando lwamaza e-millimeter, uRappaport ubonakalise indima yamaza e-millimeter kwiinethiwekhi ze-5G. Uvumile ukuba ngenxa yokuxhaphaka kwamaza e-terahertz kunye nokuphuculwa kwetekhnoloji yangoku yeselula, abantu baza kubona ii-smartphones ezinobuchule bekhompyutha obufana nobobuchopho bomntu kungekudala.
Kakade ke, ngandlela ithile, konke oku kuqikelelwa kakhulu. Kodwa ukuba indlela yophuhliso iyaqhubeka njengoko injalo ngoku, singalindela ukubona abaqhubi beefowuni besebenzisa amaza e-terahertz kubuchwepheshe bonxibelelwano kwiminyaka elishumi ezayo.
