Abakhiqizi befoni kanye nabathwali befoni abavame ukuhlaziya amanethiwekhi abo noma amafoni njengo 4G (noma ngezinye izikhathi 4G LTE). Kodwa lokho kusho ukuthini ngempela? I- iPhone 4 ne- iPhone 4S ngezinye izikhathi ibizwa ngokuthi yi-iPhone 4G, kodwa lokho kusho ukuthi i-iPhone 4 ifoni ye-4G?
Impendulo emfushane: Cha, i-iPhone 4 ne-iPhone 4S ayikho ama-4G Phones.
Lokhu kusho konke: i-iPhone 4 ne-4S ayikho amafoni angu-4G-okungenani abengekho lapho ethi "4G" usho izinga elijwayelekile le-network yeselula ye -4G noma ye-4G LTE (umlandeli kumgangatho we- 3G osetshenziswa yi-iPhone 4 & 4S). Yilokho izinkampani eziningi zefoni ezisho uma zithi "4G." Ukuqonda ukudideka kudinga ukuqonda ukuthi yini abantu abakushoyo uma bethi into i-4G. Isizathu salokhu umbuzo nhlobo ngoba kunezincazelo ezimbili ezihlukene ze "4G."
I-4G & # 61; 4th Generation Cellular Network
Lapho izinkampani eziningi, kanye nabanye abantu, bekhuluma ngo-4G, lokho okushoyo ifoni ehambisana nesizukulwane sesine (ie 4G) inethiwekhi yocingo leselula.
Amanethiwekhi we-4G, okuthiwa ne-LTE Advanced noma Amanethiwekhi e-WiMAX (phakathi kwamanye amagama), amanethiwekhi angenazintambo ezingenazintambo ezisetshenziswa izinkampani zamaselula ukudlulisela izingcingo nedatha kumakhalekhukhwini. Lokhu kuhluke ku- "3G," okubhekisela kunethiwekhi yesithathu yesitulo noma idivaysi ehambisana nenye.
Amanethiwekhi we-4G amasha, amanethiwekhi athuthukile kakhulu ashintsha amanethiwekhi we-3G. Ngokuqhathanisa, amanethiwekhi we-4G ayashesha kunamanethiwekhi we-3G futhi angathwala idatha eyengeziwe:
- Ukuvinjelwa kwenethiwekhi ye-4G: kufike ku-1 GBit / yesibili ukulanda; Ukulayisha ama-Mbit / wesibili ama-500
- Ukuvinjelwa kwenethiwekhi ye-3G: kufinyelele ku-14.4 Amamitha / wesibini ukulanda; 5.8 Mbit / yesibili ukulayisha.
Ngenkathi zikhona ezinye ze-deadspots ezitholakala ku-4G, izindawo eziningi ezweni lonke (e-US, okungenani) manje inezinsizakalo ze-4G LTE ezitholakalayo ngeselula nakuma-smartphones.
Ufuna ukufunda okuningi okuningiliziwe, ulwazi lobuchwepheshe mayelana nokuthi amanethiwekhi we-4G asebenza kanjani futhi yini eyenza ahluke kwamanye amanethiwekhi? Isihloko se-Wikipedia kumanethiwekhi e-4G yindawo enhle yokuqala.
I-4G & # 61; I-Generation Phone 4
Kukhona futhi okunye okushiwo "4G." Ngezinye izikhathi abantu basebenzisa igama elithi 4G ukusho imikhiqizo yesizukulwane sesine ngokuvamile, hhayi amanethiwekhi we-4G ngokuqondile. I-iPhone 4, njengoba igama lingasikisela, imodeli ye-4 ye-iPhone, okwenza i-iPhone yesizukulwane sesine. Kodwa ukuthi ifoni yesizukulwane sesi-4 akuyona into efanayo nokube ifoni ye-4G.
I-iPhone 4 ayiyona ifoni ye-4G
Amafoni 4G amafoni asebenza kumanethiwekhi we-4G. Njengamamodeli ase-iPhone adlule, i-iPhone 4 ayihambisani namanethiwekhi we-4G. Ngoba i- iPhone 4 isebenzisa kuphela amanethiwekhi weselula we-3G no-EDGE, i-iPhone 4 ayiyona ifoni ye-4G.
Akunjalo ne-iPhone 4S
I- iPhone 4S ingalanda idatha ngokushesha-up 14.4 Mbps-kune-iPhone 4, ekhishwa ku-7.2 Mbps. Lokhu akulona isivinini se-4G, kodwa ezinye izinkampani zamaselula zingakhuthaza i-iPhone 4S njengendlela yefoni ye-4G noma eduze nefoni ye-4G. Ngokuqinisekile, lokhu akulona iqiniso. Njengoba kuphawuliwe ngenhla, uku-4G kudinga ukuhambisana nhlobo oluthile lwenethiwekhi yeselula kanye nezinhlamvu ezithile efonini. I-iPhone 4S ayinayo lezi chips. Izinkampani zefoni ezithengisa i-iPhone e-US zinamanethiwekhi amaningi we-4G, kodwa le model ye-iPhone ayisebenzisi.
Kuthiwani nge-iPhone 5 namaModeli amasha?
Nakhu lapho izinto zilula khona: I-iPhone 5 kanye nazo zonke izinhlobo ze-iPhone ezilandelayo zingamafoni angu-4G. Kungenxa yokuthi bonke basekela amanethiwekhi we-4G LTE. Ngakho-ke, uma ufuna ukuthola i-4G LTE yesipiliyoni sedatha yeselula esheshayo, thatha i-iPhone yakamuva. Umbuzo oyodingeka uphendule uwukuthi: iyiphi imodeli engcono kakhulu ngezidingo zakho ?
