Abenzi befowuni kunye neefowuni zefowuni zihlala zixuba amanethiwekhi okanye iifowuni njenge-4G (okanye ngezinye ii-4G LTE). Kodwa oko kuthetha ukuthini ngempela? I- iPhone 4 kunye ne- iPhone 4S ngamanye amaxesha kuthiwa yi-iPhone 4G, kodwa ngaba oko kuthetha ukuba i-iPhone 4 ifowuni ye-4G?
Impendulo emfutshane: Hayi, i-iPhone 4 ne-iPhone 4S azikho ii-4G zeeFoni.
Oku kuthetha konke: i-iPhone 4 kunye ne-4S ayikho i-4G ifowuni-ubuncinci abayiyo xa ithi "4G" uthetha umgangatho wenethiwekhi yeselula ye -4G okanye ye- 4G LTE (umlandeli kumgangatho we-3G osetyenziswa yi-iPhone 4 & 4S). Yiloo nto ininzi iinkampani zeefowuni ezithethayo xa zithi "4G." Ukuqonda ukudideka kudinga ukuqonda ukuba bathini abantu xa bethetha into engama-4G. Isizathu sokuba lo ngumbuzo nantoni kukuba zimbini iintetho ezahlukeneyo ze "4G."
4G & # 61; I-4th Generation Cellular Network
Xa ezininzi iinkampani, kunye nabanye abantu, bathetha ngo-4G, oko bathethayo ifowuni ehambelana nesizukulwana sesine (oko kukuthi 4G) inethiwekhi yocingo yeselula.
Ii-4G amanethiwekhi, ezibizwa ngokuba yi-LTE Advanced okanye iinqununu ze-WiMAX amanethiwekhi (phakathi kwamanye amagama), izixhobo zengeniso ezingenazintambo ezingasetyenziselwa iinkampani zeshoni zefowuni ukuhambisa iifowuni kunye nedatha kwiifowuni zeselula. Oku kuhluke kwi "3G," ebhekiselele kwinethiwekhi yesithathu yesitulo okanye isixhobo esifana nesinye.
Iinqununu ze-4G zintsha, amanethiwekhi amaninzi atshintshe amanethiwekhi 3G. Ngokuthelekiswa, amanethiwekhi angama- 4G ahambelana noonxibelelwano lwe- 3G kwaye angakwazi ukuqhuba idatha engakumbi:
- Isantya seenethiwekhi ze- 4G: kufike kwi-1 GBit / yesibini yokukhuphela; Iimitha eziyi-500 / ukulayisha okwesibili
- Isivinini seenethwekhi ze-3G: ukuya ku-14.4 kwiMbits / yesibini ukukhuphela; 5.8 Mbit / yesibini ukulayisha.
Nangona kukho ezinye iindawo zokufa kwi-4G, iindawo ezininzi kwilizwe lonke (e-US, ubuncinane) ngoku zinemisebenzi ye-4G LTE efumanekayo kwiseli kunye nee-smartphone.
Ngaba ufuna ukufunda ngokubanzi, iinkcukacha zobuchwepheshe malunga nendlela amanethiwekhi angama 4G asebenza ngayo kwaye yintoni eyenza ihluke kwezinye iinqanethi? Inqaku le-Wikipedia kumanethiwekhi e-4G yindawo enhle yokuqala.
4G & # 61; Isizukulwana sesi-4
Kukho enye intsingiselo ye "4G." Ngamanye amaxesha abantu basebenzisa i-4G ukuthetha izityalo zesizukulwana sesine ngokubanzi, kungekhona iinqununu ezine-4G. I-iPhone 4, njengokuba igama liza kuphakamisa, imodeli ye-iPhone ye-4, eyenza i-iPhone yesizukulwane sesi-4. Kodwa ukuba isizukulwana sesi-4 asikho enye into efana ne-4G yefowuni.
I-iPhone 4 Ayikho ifowuni ye-4G
Ii-4G zefowuni ziifowuni ezisebenza kwiinqununu ze-4G. Kanye njengemodeli yangaphambili ye-iPhone, i-iPhone 4 ayihambelani neenethiwekhi ezine-4G. Ngenxa yokuba i- iPhone 4 isebenzisa kuphela ii-3G kunye ne-EDGE amanethiwekhi eselula, i-iPhone 4 ayikho ifowuni ye-4G.
Ayikho i-iPhone 4S
I- iPhone 4S inokukhuphela idatha ngokukhawuleza i-14.4 Mbps-ngaphezu kwe-iPhone 4, ekhupha i-7.2 Mbps. Oku akusiyo ijubane le-4G, kodwa ezinye iinkampani zeefowuni zingakhuthaza i-iPhone 4S njengefowuni ye-4G okanye ifowuni ye-4G. Ngokwenene, oku akunjalo. Njengoko kuchazwe ngentla, ukuba 4G kudinga ukuhambelana noluhlobo oluthile lwenethiwekhi yeselfowuni kunye neefayili ezithile kwifowuni. I-iPhone 4S ayinayo le chips. Iinkampani zeefowuni ezithengisa i-iPhone e-US zinamanethiwekhi amaninzi e-4G, kodwa le ndlela ye-iPhone ayisebenzisi.
Kuthiwani nge-iPhone 5 kunye neModeli emitsha?
Nakhu apho izinto zilula khona: I-iPhone 5 kunye nayo yonke imifanekiso ye-iPhone elandelayo i-4G ifowuni. Kungenxa yokuba bonke baxhasa amanethiwekhi e-4G LTE. Ngoko ke, ukuba ufuna ukufumana i-4G LTE kwi-data ye-data esheshayo, yenza i-iPhone yakutsha. Umbuzo oza kufuneka uphendule ngawo: nguwuphi na umzekelo okona mfuneko kwiimfuno zakho ?
