I-iPhone 12 ingahle ingabi nokuhambisana kwe-5G 700MHz, kusho ukuthini lokho?

Amahemuhemu wakamuva ayakuqinisekisa lokho i-iPhone 12 ibingeke ibe nokuxhaswa kwebhendi ye-700MHz yamanethiwekhi we-5G. Kusho ukuthini lokhu futhi kungaba namiphi imiphumela?

I-5G iyindida yangempela kwabaningi bethu, enamaqiniso angama-uhhafu angenakubalwa, amanga angaphelele kanye nemininingwane yezobuchwepheshe abantu abaningi abadlula thina. Noma kunjalo kule ndatshana sizozama ukukuchaza ngendlela yokuthi wonke umuntu onentshisekelo angakuqonda.

Izinhlobo ezimbili ze-5G: I-Sub-6Ghz ne-mmWave

Uma ukhuluma ngobuhle be-5G, imvamisa uhlala ukhuluma nge 5g zwe. Lobu buchwepheshe busebenzisa amabhendi wemvamisa ephezulu asukela ku-24GHz kuye ku-40GHz, anejubane elingaphezulu (kufika ku-5Gbps), ukubambezeleka okuncane kanye nethuba lokuvumela ukuxhumana okungapheli ngasikhathi sinye. Kodwa-ke, lobu buchwepheshe be-mmWave budinga ukuthi ube seduze ne-eriyali yeselula, ngoba ibanga elinalo lincane futhi futhi alidluli ezindongeni. Okwamanje lobu buchwepheshe butholakala ezindaweni ezimbalwa kakhulu, noma e-United States ubukhona bayo cishe buyi-anecdotal. ESpain, akukaziwa ukuthi indali izobanjwa nini ukuze opharetha bakwazi ukusebenzisa la mabhendi aphezulu.

Sinefayela le- I-5G Sub-6GHz, esebenzisa amabhendi angaphansi kwe-6GHz. Le yiyo esetshenziswa njengamanje eSpain, opharetha abahlukene basebenzisa amabhendi e-3,7GHz abengabokuqala ukuthengiswa endalini. Kuyi-5G eyiqiniso, kepha ayinikezi umkhawulokudonsa we-5G mmWave yize ngokubuyisela kuthuthukisa ukumbozwa, okuthi ngaphandle kokuba kubanzi kakhulu kudlule kakhulu okwe-5G mmWave. Isivinini esinikezwa yile 5G Sub-6GHz siphakeme kunaleso se-4G, sifinyelela ku-200Mbps.

700MHz, edingekayo ezindaweni ezingavunyelwe abantu

Indali elandelayo yokuthunyelwa kwe-5G kuzoba yiyo ethinta imvamisa ye-700MHz. Le bhendi yemvamisa ephansi ithakazelisa kakhulu ngoba, yize inikeza umkhawulokudonsa onomkhawulo kakhulu, ububanzi bayo bukhulu kakhulu futhi bungawela izithiyo. Ijubane elizosinikeza lona lizoba phansi, i-latency ibe nkulu futhi lizogcwala kalula uma kunabantu abaningi abaxhunyiwe. Manje kungani unesithakazelo esingaka? Ngoba kuzoba yiyo evumela i-5G ukuthi iyiswe ezindaweni ezinabantu abaningi, lapho kungenzeki khona ngobuchwepheshe ukubeka izimpondo eziningi, futhi lapho inani labantu lingasuthisi khona. Ngezinhloso ezisebenzayo, akwaziwa ukuthi iziphi izinzuzo le 5G 700MHz ezoba nayo uma iqhathaniswa ne-4G esinayo njengamanje.

I-5G ku-iPhone 12

Amahemuhemu wakamuva akhombisa lokho i-iPhone 12 elandelayo ibingeke ibe nokusekelwa kwe-5G mmWave ngaphandle kwase-United States, uthengisa ngamamodeli akuleli kuphela nge-5G Sub-6GHz. Uma sinaka ukuthi asazi nokuthi ukusetshenziswa kwalolu hlobo lwenethiwekhi kuzoqala nini ukuvunyelwa eSpain, iqiniso ukuthi akubonakali kuyinto ezosithinta kakhulu, iminyaka emibili noma emithathu ezayo. Kodwa futhi kuvele amahlebezi okuthi i-iPhone 12 ingahle ingasekeli imvamisa ye-700MHz kunoma yiliphi izwe emhlabeni, okungaba yinkinga, yize kuncane kunalokho abaningi abakucabangayo.

I-5G ayixhunyanisiwe ne-700MHz, empeleni njengamanje amabhendi asetshenziswayo, njengoba sibonisile ngaphambili, lawo we-3,7GHz. Ngaphezu kwalokho, ezinye zizofakwa ngokuhamba kwesikhathi, njenge-1.5GHz ne-2.3 GHz. Inkinga izoba kulezo zindawo ezingenabantu abaningi nezihlakazeke kakhulu la mabhande angasetshenziswanga kuzo futhi kuya ngemvamisa ye-700MHz, lapho i-iPhone yakho ngeke ikwazi ukusebenzisa i-5G, noma kunjalo bazoba ne-4G etholakalayo njengakuqala.
