Izolo Verizon "Uchwechwe" kumsitho we-Apple ukuze athathe ithuba lothungelwano lwe-5G ekhawulezayo. Kwaye kubonakala ngathi i-Apple yenze i-iPhone 12 entsha ukuba ifanele wena. Kuphela i-iPhone 12 kunye ne-12 Pro entsha ehambelana ne-5G mmWave band iya kuthengiswa e-US. Kumazwe aseleyo, kufuneka sizinze kwi-sub-6GHz band.
Ke kunokubonakala ngathi kuyaphoxa, kodwa inyani yeyokuba ibhendi edumileyo ye-Ultra-fast mmWave apha eSpain nakumazwe amaninzi, akukho, kwaye akulindelwe, Ubuncinci kwixesha elifutshane. Ngoko kufuneka sizole. Ngaphandle kokuba uhlala kanye phantsi kwenye yee-eriyali zovavanyo ze-Ultra-fast 5G ezikhoyo eMadrid naseBarcelona.
Kwinqaku eliphambili layizolo, ifemu yonxibelelwano yaseMelika iVerizon isinike iklasi enkulu malunga noncedo lwayo. Inethiwekhi ye-5G ekhawulezayo kunye nendlela i-iPhone 12 entsha eza kuxhamla ngayo kuyo ngokuhambelana kwayo. Ingxaki kukuba ngaphandle kwe-United States, obu bugcisa buza kuthatha iminyaka ukuba bubonwe.
Ithiyori encinci malunga ne-5G
Apha sinokubona umehluko kwi-coverage ye-5G kunye ne-4G
Ithiyori ye-Ultra-fast 5G network (mmWave) kuhle kakhulu. Le teknoloji isebenzisa iibhendi eziphezulu ze-frequency ukusuka kwi-24GHz ukuya kwi-40GHz, kwaye ngaloo ndlela ifikelele kwizinga eliphezulu kakhulu lokudluliselwa (ukuya kwi-5Gbps), i-latency encinci kunye nokwenzeka kokuvumela inani elikhulu lokudibanisa kwangaxeshanye.
Kodwa ine-drawback enkulu ekungekho mntu uthetha ngayo: le 5G ikhawulezayo ifuna ukuba ube yiyo isondele kakhulu ye-eriyali yenethiwekhi ephathwayo, kuba uluhlu lwayo lulinganiselwe kakhulu kwaye lulahlekelwa kuko konke ukusebenza kwayo ukuba kukho iindonga phakathi kwe-eriyali yenkampani kunye nesixhobo.
EUnited States kuphela yamkelwe okwangoku ngokuqala inethiwekhi encinci yee-eriyali ngobu buchwepheshe. ESpain akukaziwa ukuba ifandesi iya kubanjwa nini ukuze abaqhubi bakwazi ukusebenzisa la mabhendi aphezulu. Ke siseneminyaka embalwa kude ne-5G mmWave ibe yinyani kubasebenzisi. ESpain, naseYurophu.
Amanye amazwe, kubandakanywa ne-United States, bahambisa ii-eriyali zabo ngokukhawuleza, kodwa okusebenzayo ngakumbi kwi-5G. Ibizwa ngokuba yi-5G Sub-6GHz. Le teknoloji isebenzisa iibhendi ezingaphantsi kwe-6GHz. Le yile isetyenziswayo ngoku eSpain, kunye nothungelwano lwee-eriyali ezisetyenziswayo ngoku ezisebenzisa i-3,7 GHz bands eyayingabokuqala ukuthengiswa.
Iseyi-5G yokwenyani, kodwa ngokucacileyo "icotha" kunale ichazwe ngasentla. Iphakathi kwe-Ultra-fast 5G kunye ne-4G yangoku, ifikelela kuyo 200Mbps. Uluhlu lwayo lukhulu kakhulu, kwaye alubonisi iingxaki kwizakhiwo zokwakha, ngaloo ndlela iququzelela ukuthunyelwa kwayo kubaqhubi.
Iyahambelana ne-sub-6Ghz kwi-700Mhz
Oku akukhawulezi kangako i-5G ingasetyenziswa kwii-eriyali eziphantsi rhoqo 700 Mhz. Le bhendi ye-frequency ephantsi inomdla kakhulu kuba, nangona inika i-bandwidth encinci kakhulu, uluhlu lwayo lukhulu kakhulu kwaye lunokudlula imiqobo. Izantya eziya kusinika zona ziya kuba ngaphantsi, i-latency ephezulu kwaye iya kuhluthwa ngokulula ngakumbi xa kukho abantu abaninzi abaxhunyiwe.
Nangona kunjalo, ekusebenzeni yinethiwekhi eya kusetyenziselwa imimandla yasemaphandleni ayinabantu abaninzi, inommandla omkhulu wokugubungela. I-United Kingdom, umzekelo, ifaka inethiwekhi ebanzi yee-eriyali kunye nale frikhwensi ye-5G yayo. apha eSpain inokuhanjiswa, kodwa isabonakala.
Ngamafutshane, wonke umntu uzolile
Ukuba ufunda kuphela isihloko, kunokubonakala ngathi kuyadanisa ukungakwazi ukuthenga i-iPhone 12 egubungela itekhnoloji ezimbini ze-5G ezikhoyo ngoku. Kodwa xa kufikwa kuyo, oku Ayisichaphazeli kwaphela.. Okokuqala, kuba iya kuba yiminyaka eliqela ngaphambi kokuba i-Ultra-fast 5G iqale ukuthunyelwa kwilizwe lethu.
Kwaye okwesibini kuba nge-iPhone 12 entsha siqinisekisile ukuhambelana nayo inethiwekhi yangoku ye-5G sub-6Ghz zifakwe kwilizwe lethu nakulo lonke elaseYurophu, ngamaza awo ahlukeneyo ee-eriyali, kuquka i-700 Ghz, into eyayinexhala kubasebenzisi base-United Kingdom. Inethiwekhi ye-low-frequency engekasetyenziswa eSpain kodwa, masingakhohlisi, iya kufika phambi kwe-Ultra-fast mmWave.
