Izolo Verizon "wanyonyoba" emcimbini we-Apple ukukhipha isifuba sakhe kumanethiwekhi ayo we-Ultra-fast 5G. Futhi kubonakala sengathi i-Apple idizayine i-iPhone 12 entsha ukuze ivumelane nawe. Kuphela yi-iPhone 12 ne-12 Pro entsha ehambisana nebhendi ye-5G mmWave ezothengiswa e-US Kuwo wonke amanye amazwe, kufanele sikhokhele i-sub-6GHz band.
Ngakho-ke ngesikebhe maduzane kubonakala njengokudumazeka, kepha iqiniso ukuthi iqembu elidumile le-mmWave ultra lapha eSpain nasemazweni amaningi, akukho, futhi akulindelekile, Okungenani esikhathini esifushane. Ngakho-ke kufanele sizole. Ngaphandle kokuthi uhlala ngaphansi nje kwelinye lama-antenna wokuhlola okusheshayo we-5G Ultra akhona eMadrid naseBarcelona.
Enkulumweni eyizolo, inkampani yezokuxhumana yaseMelika iVerizon isinikeze isigaba esiphakeme ngezinzuzo zayo inethiwekhi ye-5G esheshayo nokuthi i-iPhone 12 entsha izozuza kanjani ngayo ngokuhambisana kwayo. Inkinga ukuthi ngaphandle kwe-United States, lobu buchwepheshe busazothatha iminyaka ukubonakala.
Umbono omncane nge-5G
Lapha singabona umehluko ekusetshenzisweni kwe-5G ne-4G
Umbono wenethiwekhi ye-5G Ultra-fast (mmWavekuhle kakhulu. Lobu buchwepheshe busebenzisa amabhendi wemvamisa ephezulu asukela ku-24GHz kuye ku-40GHz, futhi ngaleyo ndlela ikwazi ukufeza izinga lokudlulisa eliphakeme kakhulu (kuze kufike ku-5Gbps), ukubambezeleka okuncane kanye nethuba lokuvumela inani elikhulu lokuxhuma ngasikhathi sinye.
Kepha kunenkinga enkulu lapho kungekho muntu okhuluma ngayo: le 5G esheshayo idinga ukuthi ube yiyo kusondelene ye-antenna yenethiwekhi yeselula, ngoba ibanga elinalo lilinganiselwe kakhulu futhi lilahlekelwa nakho konke ukusebenza kwalo uma kunezindonga phakathi kwe-antenna yenkampani nedivayisi.
I-United States kuphela yamukele okwamanje ukuqala inethiwekhi elinganiselwe kakhulu yezimpondo ngalobu buchwepheshe. ESpain, akukaziwa ukuthi indali izobanjwa nini ukuze opharetha bakwazi ukusebenzisa la mabhendi aphezulu. Ngakho-ke sisasalelwe yiminyaka embalwa ngaphambi kokuba i-5G mmWave ibe ngokoqobo kubasebenzisi. ESpain, naseYurophu.
Amanye amazwe, kufaka phakathi i-United States, bathumela ama-antenna abo nge-5G hhayi ngokushesha okukhulu, kepha okusebenzayo. Ibizwa ngokuthi i-5G Sub-6GHz. Lobu buchwepheshe busebenzisa amabhendi angaphansi kwe-6GHz. Le yiyo esetshenziswa njengamanje eSpain, njengamanje isebenzisa inethiwekhi yezimpondo ezisebenzisa amabhendi e-3,7 GHz abengabokuqala ukuthengiswa endalini.
Kuseseyi-5G yangempela, kepha ngokusobala "ihamba kancane" kunalena echazwe ngenhla. Kuphakathi kwe-5G Ultra esheshayo ne-4G yamanje, efinyelela ku 200Mbps. Ukufinyeleleka kwayo kukhulu kakhulu, futhi akuvezi izinkinga ngezakhiwo zamabhilidi, ngaleyo ndlela kusiza ukuthunyelwa kwawo kubahlinzeki.
Ihambisana ne- sub-6Ghz to 700 Mhz
Le 5G ayisheshisi kangako, ingasetshenziswa kuma-antenna ejwayelekile aphansi ku- I-700 Mhz. 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.
Esikhundleni salokho, ekusebenzeni kuyinethiwekhi ezosetshenziselwa izindawo zasemakhaya inabantu abaningi, inendawo enkudlwana yokumbozwa. I-UK, ngokwesibonelo, ifaka uhlu olubanzi lwama-antenna ngalemvamisa ye-5G yayo. lapha eSpain kungavela, kepha kusazobonakala.
Ngamafuphi, wonke umuntu uzolile
Uma ufunda kuphela isihloko, kungabonakala njengokudumazeka ukungakwazi ukuthenga i-iPhone 12 ehlanganisa ubuchwepheshe obubili be-5G obukhona namuhla. Kepha lapho i-Push iza ukushova, lokhu akusithinti nakancane. Okokuqala, ngoba kuzothatha iminyaka eminingana ngaphambi kokuba i-Ultra-fast 5G iqale ukusetshenziswa ezweni lethu.
Futhi okwesibili, ngoba nge-iPhone 12 entsha sikuqinisekisile ukuhambisana nayo inethiwekhi yamanje ye-5G sub-6Ghz Kuthunyelwe ezweni lakithi nakulo lonke elaseYurophu, nezimpawu zalo ezahlukahlukene ze-antenna, kufaka phakathi i-700 Ghz., into ethinta abasebenzisi e-United Kingdom. Inethiwekhi yemvamisa ephansi engakafakwa eSpain kepha, ungalenzi iphutha, izofika ngaphambi kwe-Ultra fast mmWave.
