Impendulo emfutshane kulo mbuzo ngu-HAYI. Ngokucacileyo awungenanga kweli nqaku ukuze ubone ukuba kufanelekile ukuthenga iselfowuni ngetekhnoloji ye5G ngo-2020 okanye ngo-2021 ngaphandle kokufumana iimpikiswano ezinamandla zokuxhasa impendulo engeyiyo.
Los Izizathu zokuba ungacebisi ukuthenga i-5G mobile Ngo-2020 okanye ngo-2021 zahlukile kwaye uninzi lwazo lubangelwa yinto yokuba obu buchwephesha busetyenziswa kancinci kancinci kwamanye amazwe kwaye ayizizo zonke iimobile ezipapashiweyo njengezihambelana ne5G.
Kule nqaku ndiza kuphikisana nayo Amagama aqondwa ngumntu wonkeAkucetyiswa ukuba uthenge iselfowuni ye-5G ehlawula iindleko ezongezelelekileyo oku kuthetha ukuba kwixabiso.
Yintoni itekhnoloji ye5G
Into yokuqala ekufuneka siyazi ngale teknoloji kukuba ayenzelwanga uluntu ngokubanzi kodwa kwizixhobo ze-smart (kungekuphela ekhaya), ukuqhuba ngokuzimela njengoko kunciphisa amaxesha okuphendula (latency) kwangoko.
Iinethiwekhi ze5G, njengoko inani labo libonisa, zimele Inethiwekhi yesihlanu yeselfowuni. Isizukulwana sokuqala sasivumela ukutsala umnxeba, ngelixa iinethiwekhi ze-2G zongeza inkxaso yokuthumela imiyalezo. Ngeenethiwekhi ze-3G, i-intanethi ifikelele kwizixhobo eziphathwayo. I-4G yenza ukuba iividiyo zokusasaza zidlalwe kwaye iinethiwekhi ze5G zifikile ukunciphisa amaxesha okulinda kunye nokunyusa isantya sokukhuphela.
Iinethiwekhi ze-5G azikho mbi, okanye zingcono, kunokuba iziphumo zempilo inethiwekhi yangoku ye-4G inokuba nayo. Ngokwe-World Health Organisation, uphononongo olwenziwe malunga nokuvezwa kwabantu kumaza erediyo (iinethiwekhi ze-Wi-Fi, iBluetooth, zonke iinethiwekhi ...) bagqibe ekubeni bandise amathuba okuba nomhlaza okanye nayiphi na esinye isifo.
Zingaphi iintlobo ze5G ezikhoyo
Ukuba sithetha ngeenethiwekhi ze5G, kufuneka sithethe ngazo I-5G NSA kunye ne-5G SA iinethiwekhi. Ngale nto andibhekiseli kwinkcazo yeetshipsi esinokuzifumana ngoku kwii-smartphones esele zinika olu nxibelelwano, kodwa kwindlela esiza kuyilandela ukuze sonwabele i5G.
I-3GPP ngumbutho owazalwa ngokufika kweenethiwekhi ze-3G ukuseka imilinganiselo ye inkqubo yonxibelelwano yehlabathi. Nje ukuba iinethiwekhi ze-3G zisungulwe, ikwajongana neenethiwekhi ze-4G kwaye ngoku iinethiwekhi ze5G.
Lo mbutho uthathe isigqibo sokuba itekhnoloji ye5G iya kufezekiswa ngezigaba ezibini. Inkqubo ye- Isigaba sokuqala iya kuba ziinethiwekhi ze-NSA ze-5G kunye neyesibini i-5G SA.
I-5G NSA
Iinethiwekhi ze-NSA ze5G ayikho enye into ngaphandle 4G enevithamini Kwaye basinika, hayi kude, izibonelelo esiya kuzifumana xa iinethiwekhi ze5G zisebenza ngokupheleleyo. Iinethiwekhi ze-5G ze-NSA zezo zisasetyenziswayo ngoku, iinethiwekhi ezisebenzisa iziseko zenethiwekhi ze-4G, yiyo loo nto kungafane kubekho utshintsho lubalulekileyo kulwazi lwazo.
I-5G eMzantsi Afrika
Iinethiwekhi ze5G zoMzantsi Afrika ziinethiwekhi ezinyani iya kuba lutshintsho olukhulu kunxibelelwano olungenazingcingo, kuba zombini isantya sayo sokuhambisa kunye nokuhamba kwayo kuphezulu kakhulu kunoko sinokukufumana namhlanje kuzo zombini iinethiwekhi ze4G kunye neenethiwekhi ze5G NSA.
Ngelixa kuyinyani ukuba zombini iinethiwekhi ze-5G NSA kunye neenethiwekhi ze-5 SA zithathwa njengezikho isizukulwana esitsha sonxibelelwano olungenazingcingoAyizukude ide inethiwekhi ye-5G SA isetyenziswe ngokupheleleyo kwihlabathi liphela apho siya kuba nakho ukusebenzisa ngokupheleleyo oko basinika kona njengesantya esiphezulu soqhagamshelo, latency esezantsi, inani lezixhobo eziqhagamshelwe kwi-eriyali enye ...
4G vs. 5G NSA vs. 5G
Ukubonisa iqhosha. Ukuze sikwazi ukucacisa ngakumbi ngomahluko phakathi kwenethiwekhi ye-4G kunye neenethiwekhi ze-5G, kufuneka sijonge zombini Isantya esiphezulu sokukhuphela kunye nokubambezeleka.
Iinethiwekhi ze4G zisinika isantya esiphezulu sokukhuphela kwi-1 Gbps. Iinethiwekhi ze-NSA ze-5G ziphindwe kabini kwisantya esiya kwi-2 Gbps. Iinethiwekhi ze5G SA ziya kusinika isantya sokukhuphela esona siphezulu se-20 Gbps, Amaxesha angama-20 isantya ukuba ngoku sinokufumana namhlanje kwiinethiwekhi ze4G.
Enye into ebalulekileyo ekufuneka uyiqwalasele yi-latency. Ukubambezeleka yi ixesha elithathayo ukuba iserver iphendule kwisicelo kwaye ilinganiswa kwi-ms. Nangona kuyinyani ukuba iliso lomntu asizukufumana ezininzi ezahlukeneyo, ukuba kubalulekile ekuphunyezweni kwezithuthi ezizimeleyo, izixhobo ezifanelekileyo, iimpawu zendlela, kwimidlalo yevidiyo ...
Ukuhamba kwexesha esinokukufumana kwiinethiwekhi ze-4G kujikeleze i-30 ms. Iinethiwekhi ze-NSA ze-5G zilinqumle elo xesha ngesiqingatha. Iinethiwekhi ze5G ziya kusinika ukubambezeleka kwe1 ms, umnikelo impendulo ephantse yangoko kwizicelo.
Ukuhanjiswa kwetekhnoloji ye5G
Ukuhanjiswa kwe-5G yokugubungela kwenziwa kwizigaba ezibini. Eyokuqala kubo iya kusebenza kwiinethiwekhi ze-NSA ze-5G, iinethiwekhi Thatha ithuba lezixhobo ze4G ngoku iyafumaneka kwintengiso, inqanaba esikulo ngoku. Kude kube ngowama-2024 akulindelanga ukuba amazwe amaninzi angazukubonelela ngoqhagamshelo lokwenyani lwe-5G, hayi i-4G ene-vitamin njengoko sinokuyifumana namhlanje.
Isigaba sesibini siza kuqala ngothungelwano lwe-5 SA, uhlobo lwenethiwekhi engaxhomekekanga kuthungelwano lwe-4G nangaliphi na ixesha, ukusukela izixhobo eziyimfuneko zintsha kraca kungoko izibonelelo asinika zona zikude kakhulu kumanani omane e-4G kunye ne-5G NSA.
Ngaba kufanelekile ukuthenga iselfowuni ye-5G namhlanje?
Emva kokwazi yonke imiba ejikeleze iinethiwekhi ze5G, impendulo icace gca: Hayi. Ukuze sikwazi ukusebenzisa le teknoloji ifuna ukusinika kwisigaba sayo sokugqibela, kuya kufuneka silinde iminyaka embalwa, ngowama-2024 kwangoko (Kusenokwenzeka ukuba ngenxa yobhubhane obangelwe yi-coronavirus, loo mhla uya kulibaziseka kwaye siqwalasele i-2025).
Iifowuni ezinetekhnoloji ye5G zimalunga, I-100 euro ibiza kakhulu ukuba iimodeli ezifanayo nonxibelelwano lwe4G (abavelisi abanjengoSamsung banikezela ngeeterminal ezifanayo kwiinguqulelo ze4G kunye ne5G), iiterminal esingazukubona naluphi na uphuculo ngokubhekisele kwisantya kunye nokubambezeleka kude kube ziyafumaneka iinethiwekhi ze5G SA.
