Ukuxhumeka kwe-5G kusatshalaliswa ngokushesha futhi kabanzi emhlabeni jikelele. Inqubo iye yashesha ngisho nangaphezu kokuxhuma kwe-4G ukukhuphuka kwayo okuze ne-iPhone 5. Ingakapheli inyanga kungenzeka ukuthi I-Apple yethula i-iPhone 12 kumcimbi we-telematic ofana nowenzeka eWWDC. Emcimbini besibona izinhlobo ezine ze-iPhone 12 zonke ziyahambisana nokuxhumeka kwe-5G. Kodwa-ke, ngaphakathi kwalobu buchwepheshe kunezixhumanisi ezingaphansi ezichaza umehluko wezobuchwepheshe. Ngokufingqa, kukhona ukuxhumana okuyinhloko okubili i-5G Sub 6 ne-5G mmWave. Kungenzeka ukuthi Ukuxhumeka kwe-5G mmWave kugcinelwe i-iPhone 12 Pro Max. Sikutshela ukuthi kungani.
I-5G Sub 6 vs mmWave: Ikuphi i-iPhone 12 Pro Max?
El 5G Isizukulwane sesihlanu sokuxhumeka kweselula. Ngemuva yizizukulwane zokuqala, abazali be-SMS ne-MMS kanye ne-4G ezosala nathi futhi ekwamukele ukukhiqizwa kokusakazwa, phakathi kokunye ukusebenza. Ukufika kwe-5G kubalulekile ngezizathu ezintathu: izokwenyusa isivinini sokuphequlula sifike ku-10 GBps, i-latency izokwehliselwa ku-5 ms futhi sizokwandisa inani lamadivayisi axhunywe kunethiwekhi.
Ngale ndlela sizofinyelela ukuthi yonke into ingaxhunywa kuyo yonke into, nge-latency yokuphendula ephansi futhi yeqe isivinini sokuxhuma abasebenzisi abaningi abanaso ekhaya. Akungabazeki ukuthi i-iPhone 12 elandelayo izohambisana nokuxhuma kwe-5G. Sin embargo, los últimos informes apuntan que no todos los modelos serán compatibles con toda la sub clase de conectividad. Por un lado, el 5G Sub 6 estará disponible en el iPhone 12, iPhone 12 Pro y iPhone 12 Max. Sin embargo, un informe de Fastcompany asegura que sólo el I-iPhone 12 Pro Max izohambisana ne-5G mmWave.
Ihluke kanjani iSub 6 kwi-mmWave?
Ukuze uqonde umehluko phakathi kwalezi zindlela ezimbili ze-5G kufanele uqonde ukuthi wehluke kanjani. Futhi ikakhulukazi ku- ibhendi lapho kusetshenziswa khona ukuxhumana. ISub 6 itholakala emaqenjini angaphansi kwe-6 GhZ. Lokhu kukuvumela ukuthi ube nebanga elikhulu, bayakwazi ukudlula ezindongeni nasezintweni kepha kunokubuyela emuva: umkhawulokudonsa ungaphansi kwe-mmWave futhi basutha kalula.
Ngakolunye uhlangothi, amaqembu e-mmWave amaza aphakathi kuka-24 no-100 GhZ. Kulesi sici, isivinini esiphakeme esingaphezu kuka-10 Gbp / s siyatholakala, sigcwalisa kancane kepha ngesinye isiphazamiso: ububanzi bazo buncane futhi abadluli ezindongeni.
La I-antenna edingekayo ukusebenzisana ne-5G mmWave kungadinga isikhala esithe xaxa kune-iPhone 12 Pro Max kuphela engaba nayo. Kungakho kungenzeka ukuthi i-Apple izoshiya lokhu kuxhuma kuphela kule modeli. Kubuye kubekwe etafuleni lapho kuzothengiswa khona idivaysi enalokhu kuxhumana ngoba akuwona wonke amazwe azuze ukuthunyelwa okuhle kwamafrikhwensi angaphezu kwama-25 GhZ. Ngabe sizobona kuphela le modeli ehambelana ne-mmWave e-United States, China, noma Korea?
