Ngokusungulwa kwentengiso ye-5G, iingxoxo malunga nayo bezininzi kutshanje. Abo baqhelene ne-5G bayazi ukuba iinethiwekhi ze-5G zisebenza ngokuyintloko kwiibhendi ezimbini zefrikhwensi: i-sub-6GHz kunye namaza e-millimeter (Millimeter Waves). Ngapha koko, iinethiwekhi zethu zangoku ze-LTE zonke zisekwe kwi-sub-6GHz, ngelixa itekhnoloji ye-millimeter wave isitshixo sokuvula amandla apheleleyo exesha elinombono le-5G. Ngelishwa, ngaphandle kwamashumi eminyaka yenkqubela phambili kunxibelelwano oluphathwayo, amaza emilimitha angekangeni ngokwenene kubomi babantu ngenxa yezizathu ezahlukeneyo.
Nangona kunjalo, iingcali kwiNgqungquthela ye-5G yaseBrooklyn ngo-Epreli zacebisa ukuba amaza e-terahertz (amaza eTerahertz) anokubuyekeza iintsilelo zamaza emilimitha kwaye akhawulezise ukufezekiswa kwe-6G/7G. Amaza eTerahertz anamandla angenamkhawulo.
Ngo-Epreli, iNgqungquthela ye-6 ye-5G yaseBrooklyn yabanjwa njengoko icwangcisiwe, igubungela izihloko ezifana nokuthunyelwa kwe-5G, izifundo ezifundiweyo, kunye nembono yophuhliso lwe-5G. Ukongezelela, uNjingalwazi uGerhard Fettweis ovela kwiYunivesithi yaseDresden yeTekhnoloji kunye noTed Rappaport, umsunguli we-NYU Wireless, baxoxe ngamaza e-terahertz kwingqungquthela.
Ezi ngcali zimbini zithe abaphandi sele beqalisile ukufunda amaza e-terahertz, kwaye amaza abo aya kuba yinxalenye ebalulekileyo yesizukulwana esilandelayo sobuchwephesha obungenazingcingo. Ngethuba lokuthetha kwakhe kwi-summit, u-Fettweis waphonononga izizukulwana zangaphambili ze-teknoloji yonxibelelwano lweselula kwaye waxoxa ngamaza e-terahertz ekujonganeni nemida ye-5G. Wabonisa ukuba singena kwixesha le-5G, elibalulekileyo ekusetyenzisweni kwezobuchwepheshe ezifana ne-Intanethi yezinto (IoT) kunye ne-augmented reality / virtual reality (AR / VR). Nangona i-6G yabelana ngokufana okuninzi kunye nezizukulwana zangaphambili, iya kujongana nokusilela okuninzi.
Ngoko, ayintoni kanye kanye amaza e<em>terahertz, iingcali eziwaxabisile kangaka? Amaza eTerahertz acetywa yi-United States ngo-2004 kwaye adweliswa njengenye “yeTekhnoloji Elishumi Ephezulu Obuya Kutshintsha Ihlabathi.” Ubude bamaza bususela kwi-3 micrometers (μm) ukuya kwi-1000 μm, kwaye amaza abo asuka kwi-300 GHz ukuya kwi-3 terahertz (THz), aphezulu kuneyona ndawo iphakamileyo esetyenziswa kwi-5G, eyi-300 GHz yamaza emilimitha.
Ukusuka kulo mzobo ungasentla, kunokubonwa ukuba amaza e-terahertz alele phakathi kwamaza erediyo kunye namaza okukhanya, awanika iimpawu ezahlukileyo ukusuka kwamanye amaza ombane ukuya kumlinganiselo othile. Ngamanye amazwi, amaza e-terahertz adibanisa iingenelo zonxibelelwano lwe-microwave kunye nonxibelelwano lwamehlo, njengamazinga aphezulu othumelo, umthamo omkhulu, umkhombandlela owomeleleyo, ukhuseleko oluphezulu, kunye nokungena okunamandla.
Ngokwethiyori, kwinkalo yonxibelelwano, kokukhona inyuka i-frequency, kokukhona amandla onxibelelwano angaphezulu. Ubuninzi bamaza e-terahertz yi-odolo e-1 ukuya kwezi-4 yobukhulu obungaphezulu kunee-microwaves ezisetyenziswayo ngoku, kwaye inokubonelela ngamazinga othumelo okungenazingcingo ezingenakufikelelwa zii-microwaves. Ke ngoko, inokusombulula ingxaki yokuhanjiswa kolwazi kuthintelwe yi-bandwidth kwaye ihlangabezane neemfuno zebhendi zabasebenzisi.
Amaza eTerahertz kulindeleke ukuba asetyenziswe kubuchwephesha bonxibelelwano kule minyaka ilishumi izayo. Nangona iingcali ezininzi zikholelwa ukuba amaza e-terahertz aza kuliguqula ishishini lonxibelelwano, akukacaci ukuba zeziphi iintsilelo ezithile abanokujongana nazo. Oku kungenxa yokuba abaqhubi beselula emhlabeni jikelele basanda kuqalisa amanethiwekhi abo e-5G, kwaye kuya kuthatha ixesha ukuchonga ukusilela.
Nangona kunjalo, iimpawu zomzimba zamaza e-terahertz sele ziqaqambile iingenelo zabo. Umzekelo, amaza e-terahertz anobude obufutshane kunye nee-frequencies eziphezulu kunamaza e-millimeter. Oku kuthetha ukuba amaza e-terahertz anokusasaza idatha ngokukhawuleza nangemithamo emikhulu. Ke ngoko, ukwazisa amaza e-terahertz kwiinethiwekhi eziphathwayo kunokujongana nokungaphumeleli kwe-5G kwi-throughput data kunye ne-latency.
U-Fettweis uphinde wabonisa iziphumo zovavanyo ngexesha lentetho yakhe, ebonisa ukuba isantya sokuhanjiswa kwamaza e-terahertz yi-1 terabyte ngesekhondi (TB/s) phakathi kweemitha ezingama-20. Nangona lo msebenzi ungagqwesileyo ngokukodwa, uTed Rappaport usakholelwa ngokuqinileyo ukuba amaza e-terahertz asisiseko se-6G yexesha elizayo kunye ne-7G.
Njengovulindlela kwintsimi yophando lwamaza e-millimeter, i-Rappaport ibonakalise indima yamaza e-millimeter kwiinethiwekhi ze-5G. Uye wavuma ukuba ngenxa yobuninzi bamaza e-terahertz kunye nokuphuculwa kobuchwepheshe beselula, abantu baya kubona kungekudala ii-smartphones ezinobuchwephesha bekhompyuter obufana nobuchopho bomntu kungekudala.
Kakade ke, ukusa kumlinganiselo othile, konke oku kuqikelelwa kakhulu. Kodwa ukuba imeko yophuhliso iyaqhubeka njengoko injalo ngoku, sinokulindela ukubona abaqhubi bemfonomfono besebenzisa amaza e-terahertz kubuchwephesha bonxibelelwano kule minyaka ilishumi izayo.
