Impendulo emfushane yalo mbuzo ithi CHA. Ngokusobala awufakanga le ndatshana ukubona ukuthi kufanele yini ukuthenga iselula enobuchwepheshe be-5G ngo-2020 noma ngo-2021 ungakutholi izimpikiswano ezinamandla zokusekela impendulo engeyona.
I-Los izizathu zokungancomi ukuthenga iselula ye-5G Ngo-2020 noma ngo-2021 zihlukene futhi iningi lazo kungenxa yokuthi lobu buchwepheshe busetshenziswa kancane kancane kwamanye amazwe nokuthi akuzona zonke izinto ezihamba phambili ezikhangiswa njenge-5G ezihambisanayo ngempela.
Kule ndatshana engizophikisana nayo amazwi aqondwa yiwo wonke umuntu, Akucetyiswa ukuthi uthenge iselula ye-5G ukhokhe izindleko ezingezekile okusho ukuthi kunani.
Buyini ubuchwepheshe be-5G
Into yokuqala okufanele siyazi ngalobu buchwepheshe ukuthi ayenzelwe umphakathi wonkana kepha kumadivayisi ahlakaniphile (hhayi kuphela ekhaya), ukushayela okuzimele njengoba kunciphisa izikhathi zokuphendula (latency) khona manjalo.
Amanethiwekhi we-5G, njengoba inombolo yawo ikhombisa, amele i- amanethiwekhi wesizukulwane sesihlanu amanethiwekhi weselula. Isizukulwane sokuqala sivumele ukushaya izingcingo kuphela, ngenkathi amanethiwekhi we-2G engeza ukusekelwa kokuthumela imiyalezo. Ngamanethiwekhi we-3G, i-inthanethi ifinyelele kumadivayisi eselula. I-4G ivumele amavidiyo okusakaza ukuthi adlalwe futhi amanethiwekhi we-5G afikile ukunciphisa izikhathi zokulinda nokukhuphula isivinini sokulanda.
Amanethiwekhi we-5G awabi mabi, noma angcono, kune imiphumela yezempilo ukuthi amanethiwekhi wamanje we-4G angaba nawo. Ngokusho kwe-World Health Organisation, ucwaningo olwenziwe maqondana nokuchayeka kwabantu ezindaweni ezinomsakazo (amanethiwekhi we-Wi-Fi, i-Bluetooth, wonke amanethiwekhi weselula ...) banqume ukuthi bandise amathuba okuba nomdlavuza noma yikuphi esinye isifo.
Zingaki izinhlobo ze-5G ezikhona
Uma sikhuluma ngamanethiwekhi we-5G, kufanele sikhulume ngawo Amanethiwekhi we-5G NSA ne-5G SA. Ngalokhu angikhulumi ngokucaciswa kwama-chip esingakuthola njengamanje kuma-smartphones asevele enikeza lokhu kuxhumana, kepha endleleni esizoyilandela ukuze sijabulele i-5G.
I-3GPP yinhlangano ezalwe ngokufika kwamanethiwekhi e-3G ukusungula imininingwane ye uhlelo lokuxhumana lomhlaba jikelele. Lapho nje kusungulwe amanethiwekhi we-3G, waphinde wanakekela amanethiwekhi we-4G futhi manje amanethiwekhi we-5G.
Le nhlangano inqume ukuthi ubuchwepheshe be-5G buzotholakala ngezigaba ezimbili. I- Isigaba sokuqala kuzoba ngamanethiwekhi we-5G NSA bese kuthi okwesibili kube yi-5G SA.
I-5G NSA
Amanethiwekhi we-5G NSA awadluli ngalutho i-4G ene-vitaminized futhi basinikeza, hhayi kude, izinzuzo esizozithola lapho amanethiwekhi we-5G esebenza ngokugcwele. Amanethiwekhi we-5G NSA yiwo asetshenziswayo njengamanje, amanethiwekhi asebenzisa ingqalasizinda yamanethiwekhi we-4G, yingakho singalutholi ushintsho olubalulekile ekucacisweni kwawo.
I-5G SA
Amanethiwekhi we-5G SA angamanethiwekhi empeleni kuzoba ushintsho olukhulu kwezokuxhumana okungenazintambo, ngoba kokubili isivinini sayo sokudlulisa kanye nokubambezeleka kwayo kuphakeme kakhulu kunalokho esingakuthola namuhla kuwo womabili amanethiwekhi we-4G nakumanethiwekhi we-5G NSA.
Yize kuliqiniso ukuthi womabili amanethiwekhi we-5G NSA namanethiwekhi we-5 SA athathwa njengalawo isizukulwane esisha sokuxhumeka okungenantamboNgeke kuze kube yilapho amanethiwekhi we-5G SA esetshenziswe ngokugcwele emhlabeni jikelele lapho sizokwazi ukusebenzisa ngokugcwele lokho abasinikeza khona njengejubane lokuxhuma okuphezulu, ukubambezeleka okuphansi, inani lamadivayisi axhunywe kwi-antenna efanayo ...
I-4G vs 5G NSA vs 5G
Ukukhombisa inkinobho. Ukuze sikwazi ukucacisa ngokwengeziwe ngomehluko phakathi kwamanethiwekhi we-4G namanethiwekhi e-5G, kufanele sibheke kuzo zombili isivinini esikhulu sokulanda nokubambezeleka.
Amanethiwekhi we-4G asinikeza isivinini esikhulu sokulanda esingu-1 Gbps. Amanethiwekhi we-5G NSA asiphinda kabili leso sivinini esiya ku-2 Gbps. Amanethiwekhi we-5G SA azosinikeza isivinini esikhulu sokulanda esingu-20 Gbps, Isivinini esiphindwe ka-20 esingayithola namuhla kumanethiwekhi we-4G.
Esinye isici esibalulekile okufanele usicabangele ukubambezeleka. Ukubambezeleka yi isikhathi esidingekayo ukuze iseva iphendule isicelo futhi kukalwa nge-ms. Noma kuyiqiniso ukuthi ngeso lomuntu ngeke sithole eziningi ezahlukahlukene, uma kubalulekile ekusetshenzisweni kwezimoto ezizimele, amadivayisi ahlakaniphile, izimpawu zomgwaqo, emidlalweni yevidiyo ...
I-latency esingayithola kumanethiwekhi we-4G icishe ibe ngama-30 ms. Amanethiwekhi we-5G NSA asike leso sikhathi phakathi. Amanethiwekhi we-5G azosinikeza ukubambezeleka kwe-1 ms, ukunikela impendulo ecishe ivele kuzicelo.
Ukuthunyelwa kobuchwepheshe be5G
Ukuthunyelwa kokufakwa kwe-5G kwenziwa ngezigaba ezimbili. Eyokuqala yalezi izosebenza amanethiwekhi we-5G NSA, amanethiwekhi lokho sisebenzise ingqalasizinda ye-4G njengamanje iyatholakala emakethe, isigaba esikuso njengamanje. Kuze kube ngo-2024 akulindelekile ukuthi amazwe amaningi angeke anikele ngokuxhumeka kwangempela kwe-5G, hhayi i-4G ene-vitaminized njengoba singathola namuhla.
Isigaba sesibili sizoqala ngamanethiwekhi we-5 SA, uhlobo lwenethiwekhi olungancikile kumanethiwekhi we-4G nganoma yisiphi isikhathi, kusukela ihadiwe edingekayo yintsha sha Ngakho-ke, izinzuzo ezisinika zona zikude kakhulu nezibalo ze-4G ne-5G NSA.
Ingabe kufanelekile ukuthenga iselula ye-5G namuhla?
Ngemuva kokwazi zonke izici ezizungeze amanethiwekhi we-5G, impendulo icace bha: Cha. Ukuze sikwazi ukusizakala ngalokho lobu buchwepheshe obufuna ukusinikeza kona esigabeni sokugcina, kuzofanele silinde iminyaka embalwa, ngo-2024 ekuqaleni (Kungenzeka ukuthi ngenxa yobhadane olubangelwe yi-coronavirus, lolo suku luzobambezeleka futhi sibheka u-2025).
Izingcingo ezinobuchwepheshe be-5G ngokwesilinganiso, Ama-euro angama-100 abiza kakhulu ukuthi amamodeli afanayo anokuxhuma kwe-4G (abakhiqizi abanjengoSamsung banikela ngamatheminali afanayo ezinhlotsheni ze-4G ne-5G), amatheminali esingeke sibone noma yikuphi ukuthuthuka ngawo ngokusheshisa nokubambezeleka kuze kube yilapho kutholakala amanethiwekhi we-5G SA
