Ukuze uqonde ukuthi i-4G ikuphi kuthebhulethi , ake siqale sifunde kabanzi mayelana nale protocol yokuzalwa yesine. Isifinyezo esithi "4G" livela egameni lesiNgisi inhlanganisela yesine, okusho "isizukulwane sesine". Kulesi simo, kuyisizukulwane sesiteshi sokudlulisa idatha esingenantambo. Ukuze uthole inamba ye-4G, u-opharetha wokuxhumana unesibopho sokudlulisa idatha ngesivinini se-100 Mbit / s. Ake sibone ukuthi yiziphi izinzuzo umnikazi wethebhulethi onokusekela i-protocol ye-4G angathola.
Izidingo ezijwayelekile
Njengoba kushiwo ngenhla, ukuze isiteshi sokuxhumana sinikezwe isimo se-4G, kufanele sihlinzeke ngesivinini sokuxhuma kumsebenzisi kusuka ku-100 kuya ku-1000 Mbps. Kuze kube manje, kukhona ubuchwepheshe ababili obanikezwa isimo se-4G. Okokuqala yi-Mobile WiMAX Release 2 (IEEE 802.16m), kanti eyesibili i-LTE Advanced (LTE-A). E-Russia, amaphilisi asekela i-4G athola futhi adlulisele idatha ku-LTE technology. Kuze kube manje, izinga lokudlulisa idatha langempela liyi-20-30 Mbit / s (izilinganiso ngaphakathi kweMoscow). Ijubane, eqinisweni, liphansi kunalokhu lishiwo, kodwa abanikazi bamadivayisi aphathekayo lokhu akwanele. Manje ake sifunde ngokuningiliziwe ukuthi yini i-4G eshoyo kuthebhulethi yomsebenzisi wanamuhla.
Izinzuzo zamathebulethi angu-4G
Okokuqala, abadlali kufanele bajabule, ngoba ngokunyuka kwejubane lokuxhuma, i-ping iyancipha kakhulu (ikhwalithi yokuxhumana ithuthukisiwe), okwenza kube lula ukudlala kusukela kuthebulethi ngisho nasemidlalweni yevidiyo eminingi enamandla njenge "Amathangi E-inthanethi". Abanikazi bethebhulethi ene-LTE (4G) ukwesekwa bangabuka ukusakaza ividiyo ngekhwalithi ephakeme, cishe ngokushesha ukulandwa umculo namafayela abezindaba. Okwamanje, kukhishwe amadivayisi amaningi asekela le protocol entsha. Esikhathini esizayo, ukutshala izimali ezibalulekile kuhlelwe ekuthuthukiseni ukufakwa kwe-4G eRussia. Njengoba ubona, ubuchwepheshe bokudluliswa kwedatha kwesizukulwane sesine bube yimpumelelo yangempela ekuhlinzekeni kwezinsizakalo ze-intanethi kubanikazi bedivaysi yeselula. Ngokusobala, maduzane ijubane lokuxhuma liyokwandisa nakakhulu, indawo yokuhlanganisa izokhula kakhulu. Uma ubuzwa ukuthi i-4G iyadingeka yini kuthebhulethi yakho, impendulo izoxhomekeka ukuthi kunesabelo se-4G ensimini lapho kusetshenziswe khona idivayisi. Ngokungeziwe, kuxhomeke ekuzimeni kwakho ukuhlanganyela ngenani elimangalisayo, ngoba ngenkathi lawa madivayisi engabizi, njengesevisi ngokwayo.
Izinkinga ze-4G
Kuyaziwa ukuthi ithebhulethi ene isiteshi se-4G inezici eziningana ezingathandeki kanye nokungafani uma kuqhathaniswa namadivayisi anomthetho wokuqala we-3G. Into ecasulayo kakhulu ukuthi ukutholakala kokubili kwezinhlelo (3G no-4G) kugajethi kuholela ekubambeni ukuthi ukusetshenziswa kwesimanje kunciphisa ukushaja kwebhethri ngo-20% ngokushesha. Ngaphezu kwalokho, ngifuna ukukhononda ngekhwalithi elimbi lenkonzo ngokwayo (isivinini se-inthanethi), ngoba liphindwe izikhathi ezinhlanu kunombono ophansi oshiwo. Amazwe amaningi asele anqobe ijubane lika-100 Mbit / s., Futhi
Embuzweni wokuthi uthenge ithebhulethi ngokusekelwa kwe-4G manje, ayikho impendulo ecacile. Uma ufuna ukudlala imidlalo yase-intanethi endleleni eya esikhungweni noma ehhovisi nge $ 30 ngenyanga (amaphakheji angabizi emidlalo ayifanele), kungani kungenjalo. Into esemqoka, ungakhohlwa ukuthwala ishaja nawe ngaso sonke isikhathi, ngoba amabhethri (ngisho amahle kakhulu) ahlale phansi amahora amane.
