I-5G izoba ngaphezu kuka-10x ngokushesha kune-4G!
I-5G yiyona entsha, kodwa okwamanje iyakhululwa, inethiwekhi yeselula ezogcina ishintshe ubuchwepheshe be- 4G okwamanje ngokuhlinzeka ngezinyathelo ezimbalwa ngokusheshisa, ukusabalalisa nokuthembeka.
Ukugxila okuyinhloko kanye nesizathu sokudinga inethiwekhi ethuthukisiwe ukusekela inamba ekhulayo yamadivayisi adinga ukungena kwe-intanethi, iningi lalo lidinga umkhawulokudonsa okuningi ukuze isebenze ngokujwayelekile ukuthi i-4G ivele ingabe isayinquma.
I-5G izosebenzisa izinhlobo ezahlukene zama-antenna, isebenze kuma frequency ama-radio frequency, hlanganisa amadivaysi amaningi ku-intanethi, unciphise ukulibaziseka, futhi uhambise ukusheshisa okusheshayo.
I-5G isebenza ngokuhlukile kune-4G
Uhlobo olusha lwenethiwekhi yeselula ngeke lube lusha uma ngabe, ngandlela-thile, luhluke ngokuphelele kunezinto ezikhona. Umehluko owodwa oluyisisekelo ukusetshenziswa kuka-5G kweziteshi zomsakazo eziyingqayizivele ukufezekisa ukuthi yiziphi izinethiwekhi ze-4G ezingakwazi.
I-spectrum yomsakazo ihlukaniswe ibe yizibopho, ngayinye enezici eziyingqayizivele njengoba uhamba ngokuya kumafreedom aphezulu. Amanethiwekhi we-4G asebenzisa ama-frequencies ngezansi kwe-6 GHz, kodwa u-5G uzosebenzisa amafremu aphezulu kakhulu ku-30 GHz kuya ku-300 GHz.
Lezi zikhathi eziphakeme kakhulu ziningi ngezizathu eziningana, okunye okubaluleke kunazo zonke ukuthi zisekela umthamo omkhulu wedatha esheshayo. Akuzona nje kuphela ezincane ezithintekayo ngemininingwane yamaselula ekhona, ngakho-ke ingasetshenziswa esikhathini esizayo ngenxa yokwenyuka kwezimfuno zomkhawulokudonsa, futhi iqondiswa kakhulu futhi ingasetshenziswa eduze kwamanye amarekhodi angenawaya ngaphandle kokuphazamisa.
Lokhu kuhluke kakhulu kunezinguquko ze-4G ezifaka idatha yomlilo kuzo zonke izikhombisi-ndlela, okungenzeka zilahle amandla womabili namandla ukuhambisa amagagasi omsakazo ezindaweni ezingafuni ngisho nokufinyelela kwi-intanethi.
I-5G iphinda isebenzise ama-wavelengths ambalwa, okusho ukuthi i-antenna ingaba yincinjana kakhulu kunama-antenna akhona ngenkathi ihlinzeka ngokulawula okuqondile okuqondisayo. Kusukela isiteshi esisodwa esisodwa singasebenzisa ama-antenna angaphezulu, kusho ukuthi i-5G izosekela amadivayisi angaphezu kuka-1 000 ngamamitha kunalokho okusekelwa yi-4G.
Konke lokhu kusho ukuthi amanethiwekhi we-5G azokwazi ukuhambisa idatha e-ultra-fast kubasebenzisi abaningi kakhulu, ngokucacile okuphezulu nokuhamba kancane.
Kodwa-ke, iningi lala mazinga aphakeme kakhulu asebenza kuphela uma kune-line ecacile, eqondile phakathi kwe-antenna nedivayisi ethola isignali. Okungaphezu kwalokho ukuthi ezinye zalezi zikhathi eziphakeme zikwazi ukungena kalula ngomswakama, imvula, nezinye izinto, okusho ukuthi azihambi kude.
Kungenxa yalezi zizathu ukuthi singalindela ama-antenna amaningi asekelwe ngokusekelwe ukusekela ama-5G, noma amancane kakhulu kuzo zonke izindlu noma isakhiwo esidinga wona noma ezinkulu ezikhona kulo lonke idolobha; mhlawumbe ngisho kokubili. Kuzophinde kube neziteshi eziningi zokuphindaphinda ukuqhuma amagagasi omsakazo ngangokunokwenzeka ukuhlinzeka ngoxhaso olude lwe-5G.
Omunye umehluko ophakathi kuka-5G no-4G wukuthi amanethiwekhi we-5G azokuqonda kangcono uhlobo lwedatha eceliwe, futhi azokwazi ukushintshela kwimodi yamandla engezansi lapho engasetshenziswa noma lapho enikeza amanani aphansi kumadivaysi athile, kodwa ushintshe Imodi ephakanyisiwe ephezulu yezinto ezifana ne-HD yevidiyo yokusakaza.
I-5G i-Lot esheshayo kune-4G
Ububanzi bomkhawulo bubhekisela kumanani wedatha angasuswa (alayishwe noma alayishwe) ngenethiwekhi kunesikhathi esinikeziwe. Lokhu kusho ukuthi ngaphansi kwezimo ezihle, uma zimbalwa kakhulu uma amanye amadivaysi noma iziphazamiso zithinta ijubane, idivayisi ingakwazi ukuzwa lokho okuyaziwa ngokuthi ngesivinini esikhulu .
Kusukela ekuboneni kwejubane elikhulu, 5G izikhathi ezingu-20 ngokushesha kune-4G . Lokhu kusho ukuthi ngesikhathi sithatha ukulanda ingxenye eyodwa yedatha nge-4G (njenge-movie), okufanayo kwakungalandwa izikhathi ezingu-20 phezu kwenethiwekhi ye-5G. Ukuyibheka ngenye indlela: ungalanda ama-movie angama-10 ngaphambi kwe-4G ingakwazi ukuletha ngisho nengxenye yokuqala yeyodwa!
I-5G inesisindo sokulanda se-20 Gb / s ngenkathi i-4G ihlala ku-1 Gb / s kuphela. Lezi zinamba zibhekisela emadivaysi angahambelani, njengokusetha okungahleliwe okungenazintambo (FWA) lapho kukhona uxhumano oluqondile lwe-wire phakathi kombhoshongo kanye nedivayisi yomsebenzisi. Ukuhamba kuyahluka uma uqala ukuhamba, njengemoto noma isitimela.
Kodwa-ke, lezi zivame ukubhekwa njengezivame "ezivamile" amadivaysi abhekana nawo, ngoba zivame ukuthi kunezici eziningi ezithinta umkhawulokudonsa. Esikhundleni salokho, kubaluleke kakhulu ukubheka ukusheshisa okungokoqobo, noma ukuhamba komkhawulokudonsa okulinganisiwe.
I-5G ayikhishwe okwamanje, ngakho-ke asikwazi ukubeka amazwana kuma-real-world experience, kodwa kulinganiselwa ukuthi u-5G uzohlinzeka ngesivinini sokulanda nsuku zonke ka-100 Mb / s, okungenani. Kunezinhlobo eziningi eziguqukayo ezithinta isivinini, kodwa amanethiwekhi we-4G avame ukubonisa isilinganiso esingaphansi kuka-10 Mb / s, okufanele enze ama-5G okungenani izikhathi ezingu-10 ngokushesha kune-4G ezweni langempela.
Yini Ongayenza 5G Ingabe 4G Ayikwazi?
Ngenxa yokuthi umehluko omkhulu kakhulu wendlela abenza ngayo, kuyacaca ukuthi i-5G izovula umgwaqo omusha esikhathini esizayo kumadivayisi weselula nokuxhumana, kodwa lokho kusho ukuthini ngempela kuwe?
I-5G izobe ikuvumela ukuthi uthumele imiyalezo, yenza izingcingo, upheqa i-intanethi, futhi usakaze amavidiyo. Eqinisweni, akukho okwamanje owenza efonini yakho, ngokuqondene ne-intanethi, kuzothathwa uma usu-5G - kuzothuthukiswa.
Amawebhusayithi azolayisha ngokushesha, amavidiyo aqaliswe ngokuzenzakalela ngaphambi kokuthanda (ngeshwa?) Ukulayisha ngisho nokusheshayo, amageyimu wabadlali abaningi abaxhumekile ku-intanethi azoyeka ukuyeka, uzobona ividiyo ebushelelezi neyiqiniso uma usebenzisa i-Skype noma i-FaceTime, njll.
I-5G ingase ibuye ngokushesha kakhulu kangangokuthi konke okwenzayo kwi-intanethi manje okubonakala sengathi iyashesha kuyobonakala sengathi iyashesha.
Uma ugcina usebenzisa i-5G ekhaya ukuze usebenzise ikhebula lakho , uzothola ukuthi ungaxhuma amanye amadivaysi akho ku-inthanethi ngesikhathi esifanayo ngaphandle kwezinkinga ze-bandwidth. Okunye ukuxhumeka kwe-intanethi ekhaya kuyashesha kangangokuthi abamane nje basekeli yonke i-tech entsha ehlangene ephuma kulezi zinsuku.
5G ekhaya uzokuvumela ukuxhuma i-smartphone yakho, i-thermostat engenazintambo, i-console yevidiyo yemidlalo, ama-smart door knobs, i- realityset ephathekayo yangempela , amakhamera wokuphepha angenazintambo, ne-laptop yonke eya e- router efanayo ngaphandle kokukhathazeka ukuthi bayoyeka ukusebenza uma bonke bebonke ngesikhathi esifanayo.
Lapho i-4G izohluleka ekuhlinzekeni yonke idatha idinga inombolo ekhulayo yamadivayisi weselula, i-5G izovula imimoya yomoya nge-tech eyengeziwe enikwe amandla nge-intanethi njengezibani zethrafikhi ezihlakaniphile, izinzwa ezingenazintambo, izindwangu zokugqoka, nokuxhumana kwezimoto nomgwaqo.
Izimoto ezithola idatha ye-GPS neminye imiyalo ebasiza ukuba baqonde umgwaqo, njengezibuyekezo zesofthiwe noma izixwayiso zethrafikhi kanye neminye imininingwane yesikhathi sangempela, kuzodinga i-intanethi ephuthumayo ukuba ihlale iphezulu - akuyona into engokoqobo ukucabanga ukuthi konke lokhu kusekelwa amanethiwekhi e-4G akhona.
Kusukela ku-5G kungathwala idatha ngokushesha kunamanethiwekhi we-4G, akusikho endaweni yokulindela ukubuka ukudluliselwa kwedatha okungaxhunyiwe, okungaxhunyiwe. Okuzokwenza lokhu ekugcineni kuvumele ukufinyelela okusheshayo kolwazi ngoba ngeke kudingeke ukuba kungagxiliwe ngaphambi kokusetshenziswa.
Uzofika nini 5G?
Awukwazi ukusebenzisa inethiwekhi ye-5G okwamanje ngoba okwamanje isigaba sokuhlola nesentuthuko, futhi amafoni we-5G akakaze afinyelele ngaphakathi.
Usuku lokukhishwa kwe-5G alusethwe ematheni kuwo wonke umhlinzeki noma izwe, kodwa iningi lifuna ukukhululwa ngo-2020. Bheka nini i-5G ifika e-US? futhi 5G Ukutholakala Emhlabeni Wonke ngolwazi oluqondile.
