Foni yevashambadziri uye nhare dzefoni dzinowanzosvibisa mitambo kana mafoni se 4G (kana dzimwe nguva 4G LTE). Asi izvozvo zvinorevei chaizvoizvo? I iPhone 4 ne iPhone 4S dzimwe nguva dzinonzi iPhone 4G, asi zvinoreva here kuti iPhone 4 i 4G foni?
Mhinduro Mhinduro: Aiwa, The iPhone 4 ne iPhone 4S haisi 4G Phones.
Izvozvo zvinoreva zvose: iPhone 4 uye 4S haisi mafoni 4G-kana kuti haisi iyo kana achiti "4G" iwe unoreva 4G kana 4G LTE seyero yemagetsi (iyo inotsiva ku 3G yezinga inoshandiswa ne iPhone 4 & 4S). Izvi ndizvo zvinowanzoshandiswa nemakambani efoni paanoti "4G." Kunzwisisa kuvhiringidzi kunoda kunzwisisa zvinorehwa nevanhu pavanotaura chimwe chinhu 4G. Chikonzero ichi ndiwo mubvunzo zvachose nokuti pane zvinoreva zvirevo zviviri zve "4G."
4G & # 61; 4th Generation Cellular Network
Apo makambani akawanda, uye vamwe vanhu, vachitaura nezve 4G, zvavanoreva ndeyefoni inofambidzana nechizvarwa chechina (kureva 4G) nhare yefoni.
4G mitambo, inonziwo LTE Advanced kana Mobile Mobile WiMAX (pakati pemamwe mazita), inotevera mitambo isina kushandiswa isina wireless inoshandiswa nemakambani ekufambisa foni kutumira foni uye deta kumaselula. Izvi zvakasiyana ne "3G," iyo inoreva chetatu yezera rese kana chigadzirwa chinowirirana neye.
4G mamanzura ari matsva, mitambo yakawanda yepamusoro iyo inotsiva mitambo yeGG. Kana tichienzanisa, mitambo ye 4G inokurumidza kupfuura mitambo ye 3G uye inogona kutakura mamwe mashoko:
- 4G mitambo yepamhanho: kusvika 1 GBit / yechipiri download; 500 Mbits / wechipiri upload
- 3G mitambo yepamhanho: kusvika kusvika 14,4 Mbiti / yechipiri download; 5.8 Mbit / yechipiri pakakanikidzwa.
Nepo kune mamwe akafaspots mu 4G kugoverwa, nzvimbo dzakawanda munyika yose (muU.S., zvishoma) iye zvino ine 4G LTE service inowanika sero nefoni.
Unoda kudzidza zvakawanda zvakanyatsorongeka, ruzivo ruzivo pamusoro pekushandiswa kwemachina 4G uye chii chinoita kuti vakwanise kubva kune mamwe maintaneti? Izwi re Wikipedia pane ma 4G network ndiyo nzvimbo yakanaka yekutanga.
4G & # 61; 4th Generation Phone
Panewo chimwe chinoreva "4G." Dzimwe nguva vanhu vanoshandisa izwi rokuti 4G kureva zvigadzirwa zvechina zvezvizvarwa zvekare, kwete maraneti 4G zvakananga. I iPhone 4 iyo, sezvinonzi zita raizokurudzira, iPhone yechina model, ichiita iyo iPhone yechizvarwa chechina. Asi kuva chikamu chechina foni hachisi chinhu chakafanana sekuve foni 4G.
I iPhone 4 Haisi 4G Phone
4G foni nhare dzinoshandiswa pamaganeti e 4G. Kungofanana nemasikirwo e iPhone apfuura, iPhone 4 haina kufambidzana namaganeti e 4G. Nokuti iPhone 4 chete inoshandisa 3G uye EDGE mitambo yesero, iPhone 4 haisi foni 4G.
Uyewo haisi iPhone 4S
Iyo iPhone 4S inokwanisa kudhinda data nekukurumidza-up 14.4 Mbps-kupfuura iPhone 4, iyo inodzinga pa 7.2 Mbps. Izvi hazvizi 4G speed, asi mamwe makambani efoni anogona kukurudzira iPhone 4S se 4G foni kana pedyo ne 4G foni. Zvechokwadi, izvi hazvisi chokwadi. Sezvataurwa pamusoro apa, kuva 4G kunoda kuwirirana nemhando yakasiyana yefoni network network uye mahwendefa chaiwo mufoni. Iyo iPhone 4S haina mahwanda aya. Nhare dzekambani dzinotengesa iPhone muUnited States dzine mazamu akawandisa e 4G, asi iyi mhando ye iPhone haina kushandisa zvayo.
Zvakadini neIfero 5 neNewer Models?
Pano ndipo pane zvinhu zvinova nyore: iPhone 5 uye yose inotevera iPhone mifananidzo ndeye 4G foni. Ndizvo nokuti ivo vose vanotsigira mazano 4G LTE. Saka, kana iwe uchida kuwana 4G LTE nokuda kwechiitiko chinonyanya kushandiswa chemashoko, tora iPhone yakapfuura. Mubvunzo waunofanirwa kupindura ndewokuti ndeupi muenzaniso wakanaka kune zvaunoda ?
