Umlo weendlela zetekhnoloji ye-5G ngokuyimfuneko ngumlo wamabhendi amaza.Okwangoku, ihlabathi lisebenzisa iibhendi ezimbini ezahlukeneyo zokusebenzisa i-5G networks, i-frequency band phakathi kwe-30-300GHz ibizwa ngokuba yi-millimeter wave;enye ibizwa ngokuba yi-Sub-6, egxile kwi-3GHz-4GHz frequency band.
Ngokuxhomekeke kwiimpawu ezibonakalayo zamaza erediyo, ubude obufutshane kunye neempawu zomqadi ezimxinwa zamaza emilimitha zivumela ukusonjululwa komqondiso, ukhuseleko losasazo, kunye nesantya sothumelo ukuze kuphuculwe, kodwa umgama wothumelo uncitshiswe kakhulu.
Ngokutsho kovavanyo lwe-5G ye-Google yoluhlu olufanayo kunye nenani elifanayo lezikhululo zesiseko, inethiwekhi ye-5G esetyenziswe ngamaza e-millimeter inokugubungela i-11.6% yabemi kwizinga le-100Mbps, kunye ne-3.9% kwizinga le-1Gbps.Inethiwekhi ye-6-band ye-5G, i-100Mbps isantya senethiwekhi inokugubungela i-57.4% yabemi, kwaye izinga le-1Gbps lingagubungela i-21.2% yabemi.
Ingabonwa ukuba ukugubungela amanethiwekhi e-5G asebenza phantsi kwe-Sub-6 ingaphezulu kwamaxesha e-5 amaza e-millimeter.Ukongeza, ukwakhiwa kwezikhululo ze-millimeter wave zifuna malunga ne-13 yezigidi zofakelo kwiipali ze-utility, eziya kuxabisa i-400 yeebhiliyoni zeedola, ukwenzela ukuba kuqinisekiswe ukugubungela i-72% kwi-100 Mbps ngesekhondi kwi-28GHz band kunye ne-55 ngesekhondi kwi-1Gbps.% ukhuseleko.I-Sub-6 idinga kuphela ukufaka isikhululo sesiseko se-5G kwisikhululo sokuqala se-4G, esigcina kakhulu iindleko zokuthunyelwa.
Ukusuka kwi-inshorensi ukuya kwiindleko zokusetyenziswa kwezorhwebo, i-Sub-6 ingaphezulu kune-mmWave kwixesha elifutshane.
Kodwa isizathu kukuba izibonelelo ze-spectrum zininzi, i-bandwidth ye-carrier inokufikelela kwi-400MHz / 800MHz, kwaye izinga lokuhanjiswa kwe-wireless linokufikelela ngaphezu kwe-10Gbps;eyesibini ngumqadi wamaza omilimitha omxinwa, ulwalathiso oluhle, kunye nesisombululo sesithuba esiphakame kakhulu;eyesithathu yimillimeter-wave components Xa kuthelekiswa ne-Sub-6GHz izixhobo, kulula ukuyinciphisa.Okwesine, ikhefu le-subcarrier likhulu, kwaye ixesha elilodwa le-SLOT (120KHz) yi-1/4 ye-frequency ephantsi ye-Sub-6GHz (30KHz), kwaye ukulibaziseka kwe-interface yomoya kuncitshisiwe.Kwizicelo zenethiwekhi zabucala, inzuzo yemilimitha yamaza iphantse yatyumza i-Sub-6.
Okwangoku, uthungelwano lwesithuthi sothungelwano lwabucala oluphunyezwa ngonxibelelwano lwe-millimeter-wave kwi-industry transit industry inokufikelela kwizinga lokuhanjiswa kwe-2.5Gbps phantsi kwe-speed-speed dynamic, kwaye ukulibaziseka kokuhanjiswa kunokufikelela kwi-0.2ms, enexabiso eliphezulu kakhulu. yenkuthazo yenethiwekhi yabucala.
Kuthungelwano lwabucala, iimeko ezifana nokuhamba ngololiwe kunye nokubeka iliso kukhuseleko loluntu kunokunika umdlalo opheleleyo kwiinzuzo zobugcisa zamaza emilimitha ukufezekisa isantya sokwenyani se-5G.
