I-4G ikhawuleza ngaphezu kwe-3G, kodwa yintoni na?
Ngokukhawuleza kulunge xa kufikelele ekufikeleleni kwe-intanethi. Oku kusebenza kungekuphela kokuphequlula okulula kodwa kwakhona ukusabalalisa kweendaba, ukukhutshwa kwezixhobo, imidlalo ye-gameplay kunye neefowuni. Kunzima ngokwaneleyo, nangona kunjalo, ukufumana ukufikelela kwe-intanethi ngokukhawuleza ekhaya, ungayishiyi isantya esiphezulu kwii-smartphones zethu kunye namacwecwe ngaphezu kwe- 4G okanye 3G .
Ngaba ufanele ukukhawuleza ukuba ulindele ukuba zixhobo zakho eziphathekayo? Icandelo lalo linxulumene nesantya somnikezeli wakho, njengeVerizon okanye i-AT & T, kodwa ezinye izinto ziza kudlala nazo zifana namandla akho okubonisa uphawu, yintoni enye esebenzayo kwisixhobo sakho, nanoma yiyiphi i- latency , enokuchaphazela ukulibaziseka, ividiyo kunye I-call call, ukuhanjiswa kwevidiyo, ukukhangeli kwewebhu, njalo njalo.
Unokuvavanya ukuba unxibelelwano olukhawulezayo kangakanani kwinethwekhi luneenkqubo ezahlukeneyo zokuvavanya iisantya , njenge-Speedtest.net yokuvavanya isantya sovavanyo olufumaneka kwi-Android kunye ne-iOS. Ukuba ufikelela kwinethiwekhi ye-4G okanye ye-3G ngekhompyutheni, funda ezi zizaziso zezantya zokuhlola .
4G kunye no-3G Ukuhamba
Nangona isantya sokuphakama kweempawu ziphela kuphela kwaye azivekanga kwiimeko zehlabathi zangempela (ngenxa yezinto ezinjenge-latency), ezi ziyimfuneko zejubane umniki-mveliso kufuneka ahlale kuzo ukuze abe noxanduva oluwela phantsi kwesigaba se-4G okanye se-3G:
- 4G : 100 Mbps ukuhamba okuphezulu njengenkonzo evela kwimoto ehambayo. I-Gbps yokuhamba okuphantsi njengokufana nokuhamba okanye ukuhamba
- 3G: 7.2 Mbps okanye 52 Mbps kwi-3G HSPA +
Nangona kunjalo, njengokuba ubona apha, isifundo esivela kwi-RootMetrics sithole umyinge, ukukhuphela kwenene kwehlabathi kunye nokulayishwa ngesivinini kwizithuthi ezine ezinezintambo ezingenazintambo e-US ukuba zihluke.
- Inethwekhi ye- AT & T ye- 4G LTE ifumaneka ukuba iyona ekhawulezileyo, ngokukhawuleza ukukhuphela kwee-18.6 Mbps kunye nokulayishwa kwesivinini se-9.0 Mbps. Inethiwekhi ye-3G eyadala, ngokuhlukileyo, i-4.3 Mbps yokukhuphela kunye nokulayishwa kwe-1.1 Mbps. Inethwekhi ye-AT & T ye-LTE ine-81.7% yokufikelela kwenethiwekhi. Isikhulu esiphezulu sokukhuphela esilinganiselweyo kule sifundo sivale inethiwekhi ye-AT & T ye-4G kwi-19.6 Mbps.
- UVerizon weza okwesibini, kunye no-14.3 Mbps ukulandwa, ngokomyinge, kunye nokukhawuleza kokulayishwa kwee-8.5 Mbps. Nangona ivela emva kwe-AT & T, iVerizon inomlinganiselo omkhulu kunye no-90%. Ijubane elikhawulezayo elilinganiselweyo laliyi-49.3 Mbps.
- I-Sprint i -10.3 Mbps yokulandwa kunye ne-4.4 Mbps yokulayishwa, kunye nenethwekhi yafikeleleka kwi-50.2% yexesha. I-32.7 Mbps yayisisantya esiphezulu seSprint.
- Intanethi ye- TSP ye- TSPA + i-7.3 Mbps yokulandwa kunye ne-1.5 Mbps yokulayishwa. Ngoko, bhetele kune-3G kodwa i-4G LTE ikhawuleza.
Indlela yokukhulisa uxhumano lwakho lwe-inthanethi
Gcina ukhumbule ukuba xa sithetha "ukukhulisa uxhumano lwakho lwe-intanethi," asinakuthetha ngokumxhoma kwizinga eliphezulu elivumelekileyo okanye ukudala uhlobo oluthile lwenxibelelwano lwe-intanethi apho kungekho mida. Endaweni yoko, ukukhulisa uxhumano lwakho lithetha ukutshitshisa nantoni na eyona nto ingenza ityeke ukuze ibuyele kwizinga elithathwa njengento eqhelekileyo.
Ukuba ufumanisa ukuba uxhumano lwakho lucotha ngaphezu kwe-4G okanye i-3G, kukho izinto ezininzi ongayenza ukuze uzame ukukhawulezisa ukuba unxibelelwano kwicala lakho.
Umzekelo, ukuba usekhompyutheni, unokwenza uxhumano lwakho lwe-intanethi ngokukhawuleza ekhaya ngokutshintsha ii- server ze-DNS ozisebenzisayo ukwenzela ukuba imiphepha yomthwalo ibonakale ngokukhawuleza (kukho uluhlu lwamaseva eDNS apha apha ). Enye indlela yokuvala ezinye iinkqubo usebenzisa i-intanethi esondayo kwi- bandwidth elinganiselwe okhoyo.
Okanye, ukuba ukhona kwi-smartphone ye-Android okanye ithebulethi, khuthaza isivinini sakho se-intanethi nge-Intanethi ye-intanethi ye-Intanethi . Incamango efanayo iya sebenza kumgama wendlela yokuhamba kwinqanaba kwiimpahla eziphathekayo. Isikhulu esiphezulu se-4G okanye i-3G isisombululo sifikeleleka ukuba awukho usebenze ezinye izinto ezininzi ngelo xesha. Umzekelo, ukuba ufuna ukulayisha ividiyo ye-YouTube ngokukhawuleza kunokwenzeka kwi-network yakho ye-4G, vala kwi-Facebook okanye kwimidlalo esebenzisa intanethi.
