I-International Air Transport Association (IATA) yamkele isivumelwano ngeeNkonzo ze-AT & T, i-T-Mobile, i-UScellular, kunye ne-Verizon ukwandisa kude kube yi-1 kaJanuwari 2028 amanyathelo okunciphisa ngokuzithandela ukuhanjiswa kwe-5G C-band kwii-airports ze-188 zase-US.
La manyathelo okunciphisa, athe amiselwa ngoJanuwari 2022, ngaxeshanye nokuqaliswa kwe Imisebenzi ye-5G C-band kwii-airports zase-US okanye ezikufutshane, zibandakanya ukunciphisa amandla okuhanjiswa kwe-5G kwaye yayimiselwe ukuphela kwe-1 kaJulayi 2023. Nangona kunjalo, ngelixa isivumelwano siluphuhliso olwamkelekileyo lokumisa i-gap, akukho nto isisombululo. Ukhuseleko olusisiseko kunye nemiba yezoqoqosho malunga nokuthunyelwa kwe-5G C-band ngababoneleli beenkonzo zonxibelelwano (i-telcos) baye bakhatywa kuphela endleleni.
“Iinqwelomoya azizange ziyidale le meko. Bangamaxhoba ocwangciso nolungelelwaniso lukarhulumente. Iinkxalabo zeshishini malunga ne-5G, echazwe iminyaka emininzi kwiiforamu ezifanelekileyo, azizange zihoywe kwaye zigqithise. Izisombululo zomlinganiselo wesiqingatha ziye zanyanzeliswa kwiinkampani zeenqwelomoya ukuba ziphumeze ngeendleko zazo kunye nokubonakala okuncinci ekusebenzeni kwazo kwexesha elide. Olu lwandiso lithuba labo bonke abachaphazelekayo, kubandakanywa i-telcos, abalawuli bakarhulumente, iinqwelomoya kunye nabavelisi bezixhobo, ukusebenzisana kwisisombululo esinobulungisa nesinobulungisa, "utshilo uNick Careen. IATA's Senior Vice President Operations, Safety and Security.
Imvelaphi kwimeko yangoku
Ukusebenza kwe-5G C-band imisebenzi ngoJanuwari 2022 kusongela ukuphazamiseka okukhulu kwinkqubo yokuthutha i-air yase-US ngenxa yomngcipheko onokuthi uphazamise i-altimeters ye-radio ye-aircraft (i-radalts) ekwasebenzisa i-spectrum ye-C-band kwaye ibaluleke kakhulu kwiinkqubo zokuhlalisa kunye nezokhuseleko. . Oku kwaqwalaselwa kuphela ngeyure yeshumi elinanye xa i-AT & T kunye ne-Verizon bavuma umda wamandla wokuzithandela we-5G C-band transmissions kufuphi neenqwelo-moya. Nangona kukho esi sivumelwano, nangona kunjalo, umngcipheko oqhubekayo wokuphazamiseka kwi-aircraft radalts wabonwa njengobaluleke kakhulu Ulawulo lwezoLawulo lwezoPhapho (i-FAA) ukuba iinqwelo-moya zivunyelwe kuphela ukuba zisebenze kwizikhululo zeenqwelo moya ezichaphazelekayo ekubonakaleni okuphantsi (uDidi 2 kunye noDidi 3) kwiimeko ngenye yeendlela ezimbini:
• IiNdlela ezizezinye zokuThobela (AMOC) apho abavelisi bezixhobo zoqobo zeenqwelo-moya kunye neenqwelo-moya (i-OEMs) bamisela ukuba indibaniselwano yenqwelo-moya / iradalt ethile inika ukomelela okwaneleyo ngokuchasene nokuphazamiseka ukuze kuqhutyekwe kusetyenziswa iinkqubo zokumisa ezibonakala zisezantsi kwizikhululo zeenqwelo-moya ezichaphazelekayo.
• Ukulungisa iiradali ezikhoyo okanye ukutshintshwa kwazo kufakwe iimodeli ezintsha ngeendleko zabo, ukunika amandla imisebenzi engathintelwanga kumanqanaba ombane e-5G ekuvunyelwene ngawo.
NgoMeyi ka-2022, i-FAA yazisa iinqwelomoya ukuba, ukususela nge-1 kaJulayi 2023 inkqubo ye-AMOC iya kuphela. Endaweni yayo, imfuneko yengubo echaza ubuncinci bomgangatho wokusebenza kwiiradali kwiinkqubo ezisezantsi ezibonakalayo zokumisa yayiza kusekwa. IiRadalts ezingawufikeleliyo umgangatho womsebenzi ophantsi kuya kufuneka zitshintshwe okanye ziphuculwe ngeendleko zenqwelomoya. Iindleko zokuphucula i-radalt yezithuthi ziqikelelwa ngaphezulu kwe-638 yezigidi zeedola.
Iinqwelomoya ezininzi zaqala inkqubo yokuphucula i-radalt kungekudala emva konxibelelwano lukaMeyi 2022 oluvela kwi-FAA, nangona i-FAA ingazange ikhuphe isaziso esisemthethweni somthetho ocetywayo de kube nguJanuwari 2023. Nangona kunjalo, imiba yokubonelela yenze ukuba kungenzeki ukuba zonke iinqwelomoya zinokuphuculwa. umhla woku-1 kaJulayi, ugrogrisa iziphazamiso zokusebenza ngexesha lencopho yohambo lohambo lwasehlotyeni.
Uphuhliso lwakutsha nje
Isivumelwano samva nje se-telcos sokurhoxisa kude kube nguJanuwari ka-2028 amandla apheleleyo e-5G C-band transmissions kufutshane nezikhululo zeenqwelo moya ithenga ixesha kodwa ayijongani nemiba esisiseko.
I-retrofits efunekayo nge-1 kaJulayi 2023 yisisombululo sexeshana njengoko ingenakukwazi ukunyamezela ngokwaneleyo ebusweni bokuhanjiswa kwamandla apheleleyo e-5G C-band. Imigangatho emitsha ye-radalt yokunyamezela kwe-5G iyaphuhliswa kodwa akulindelekanga ukuba ivunywe phambi kwesiqingatha sesibini se-2024. Emva koko, abenzi be-radalt baya kuqalisa inkqubo ende yokuyila, ukuqinisekisa nokwakha izixhobo ezitsha zokufakelwa kumawaka eenqwelo-moya ezikhoyo, njengoko. kunye nazo zonke iinqwelomoya ezintsha ezinikezelweyo phakathi kwangoku kunye no-2028. Iminyaka emine enesiqingatha lixesha elingqongqo kakhulu kwisikali sesi sibophelelo.
“Iinqwelomoya ezininzi zibonise ukuba ngaphandle kwemizamo yazo encomekayo azizuwufezekisa umhla woku-1 kaJulayi ngenxa yemicimbi yokubonelela. Kodwa nakwabo benzayo, olu tyalo-mali aluyi kuzisa nzuzo ekusebenzeni kakuhle. Ngaphaya koko, esi sisenzo sethutyana sokubamba. Phantsi kweemeko zangoku, iinkampani zeenqwelomoya kuya kufuneka zibuyisele uninzi lweenqwelomoya zazo kabini kwiminyaka nje emihlanu. Kwaye ngemigangatho yeretrofit yesibini engekaphuhliswa sinokujongana lula nemiba yokubonelela ngo-2028 esisokolayo namhlanje. Oku akunabulungisa kwaye kuyinkcitho. Sifuna indlela enengqiqo engafaki mthwalo wonke wokujongana nale meko ilishwa kuphapho,” utshilo uCareen.
