Ogwiritsira mafoni ndi othandizira mafoni nthawi zambiri amayesa ma Intaneti kapena mafoni monga 4G (kapena nthawi zina 4G LTE). Koma kodi zimenezi zikutanthauza chiyani kwenikweni? IPhone 4 ndi iPhone 4S nthawi zina amatchedwa iPhone 4G, koma kodi izo zikutanthauza kuti iPhone 4 ndi foni ya 4G?
Yankho lachidule: Ayi, iPhone 4 ndi iPhone 4S si Mafoni 4G.
Izi zikutanthauza zonse: iPhone 4 ndi 4S si ma foni 4G - mwina si pamene amati "4G" mukutanthauza 4G kapena 4G LTE makanema amtundu wa makanema (wotsatila muyezo wa 3G wogwiritsidwa ntchito ndi iPhone 4 & 4S). Izi ndi zomwe makampani ambiri a foni amatanthauza pamene akunena "4G." Kumvetsa chisokonezo kumafuna kumvetsetsa zomwe anthu amatanthauza pamene akunena kuti 4G. Chifukwa chake ichi ndi funso nchifukwa chakuti pali matanthauzo awiri osiyana a "4G."
4G & # 61; 4th Generation Cellular Network
Pamene makampani ambiri, ndi anthu ena, amalankhula za 4G, zomwe akutanthauza ndi foni yomwe imagwirizana ndi 4th (networking foni).
Mabungwe a 4G, omwe amatchedwanso LTE Advanced kapena mafoni a WiMAX (pakati pa mayina ena), ndi mawonekedwe osayendetsedwa opanda mafano omwe amagwiritsidwa ntchito ndi makampani opanga mafoni kuti atumize ma telefoni ndi mafoni. Izi ndi zosiyana ndi "3G," zomwe zimatanthawuza mzere wachitatu wa fuko kapena chipangizo chogwirizana ndi chimodzi.
Mabungwe a 4G ndi atsopano, mawonekedwe apamwamba kwambiri omwe akutsitsa mawebusaiti a 3G. Poyerekezera, maweti a 4G ali mofulumira kuposa mamembala a 3G ndipo angathe kutenga zambiri:
- 4G macheza akuthamanga: mpaka 1 GBit / seconds download; Mipikisoni 500 / kachiwiri kukweza
- Mapulogalamu a 3G akuthamanga: mpaka 14.4 Mbiti / kachiwiri kuwongolera; 5.8 Mbit / yachiwiri kukweza.
Ngakhale pali zigawo zina zakufa mu 4G, malo ambiri padziko lonse (ku US, osachepera) tsopano ali ndi 4G LTE chithandizo chopezeka pa selo ndi matelefoni.
Mukufuna kuti mudziwe zambiri, zowonjezera zokhudza momwe magulu a 4G amagwira ntchito ndi chiyani chomwe chimapangitsa iwo kukhala osiyana ndi ma intaneti ena? Nkhani ya Wikipedia pa ma Intaneti 4G ndi malo abwino kuyamba.
4G & # 61; 4th Generation Phone
Palinso tanthauzo lina la "4G." Nthaŵi zina anthu amagwiritsa ntchito mawu akuti 4G kutanthauza zamagulu achinayi, makamaka ma network 4G. IPhone 4 ndi, monga dzina likanati liwonetsedwe, mawonekedwe a iPhone 4, kuti ikhale iPhone ya m'badwo wa 4. Koma kukhala foni ya fuko lachinayi sikuli chinthu chofanana ndi kukhala foni ya 4G.
IPhone 4 Si foni ya 4G
Mafoni 4G ndi mafoni omwe amagwira ntchito pa mawebusaiti a 4G. Mofanana ndi zitsanzo za iPhone kale, iPhone 4 siyigwirizana ndi ma 4G. Chifukwa iPhone 4 imangogwiritsira ntchito makina a ma 3G ndi EDGE osakanikirana, iPhone 4 si foni ya 4G.
Ngakhalenso iPhone 4S
IPhone 4S ikhoza kutulutsa deta mofulumira 14.4 Mbps-kuposa iPhone 4, yomwe imathamanga pa 7.2 Mbps. Izi sizithamanga 4G, koma makampani ena a foni angalimbikitse iPhone 4S kukhala foni ya 4G kapena pafupi ndi foni ya 4G. Mwachidziwitso, izi si zoona. Monga tafotokozera pamwambapa, kukhala 4G kumafuna kugwirizana ndi mtundu wina wa foni yam'manja ndi makapu enaake pafoni. IPhone 4S ilibe chips ichi. Makampani a foni omwe amagulitsa iPhone ku US ali ndi mazenera ambiri a 4G, koma mawonekedwe a iPhone samagwiritsa ntchito mwayi wawo.
Nanga Bwanji iPhone 5 ndi Zatsopano Models?
Apa ndi pamene zinthu zimakhala zosavuta: iPhone 5 ndi zotsatira zonse za iPhone ndi mafoni 4G. Ndi chifukwa chakuti onse amathandizira ma Intaneti 4G LTE. Kotero, ngati mukufuna kutenga 4G LTE kwa maulendo apadera kwambiri a deta, tengani iPhone yatsopano. Funso limene muyenera kuyankha ndi: Kodi ndichitsanzo chiti chomwe mukufuna pa zosowa zanu ?
