Vese mafoni efoni anogona kusvika paWebhu, asi havasi vose vanogona kuzviita panguva imwe chete. Mamwe mafoni anokwanisa kuvhara kubva panzvimbo yekuenda kune imwe nzvimbo, kutora mafaira muchiedza, asi vamwe vanoita sevanopa kukurumidza kwete kukurumidza kuvhara-up connection.
IPhone yeApple, somuenzaniso, haikwanisi kupinda network ye AT & T yeHSDPA ; Apple inoti yakasarudza kusaisa hutsigiro hweHSDPA nokuti chipset inofanira kuve yakaita simba rakawandisa, kuderedza hupenyu hwebheteri.
Kana yakakurumidza-data data service yakakosha kwauri, iva nechokwadi chokuti foni yaunofarira inotsigira nheyo ye 3G. Uye yeuka kubvunza kana iwe unogona kuedza foni uye nhuro ye 3G usati waenda kune kontrakiti yenguva refu, kana kuidzorera iyo kana usina kufara nemabasa ayo. Yeuka: Iko kunomhanya kunogona kusiyana.
Unogona sei kuva nechokwadi kuti foni yako ichapa nokukurumidza kushandura paWebhu? Chimwe chezvinhu zvikuru ndeye ruzivo rwekufambisa iyo foni yako inotsigira-uye network iyo inotengeswa nefoni yako. A 3G, kana chikamu chechitatu, ruzivo rwepa data ruchagovera zvakakurumidza kupfuura. Hasi maseki ose eGG anoshandiswa akaenzana, zvakadaro. Chimwe nechimwe chinotakura mabhiiyo chinopa mavhenekeri (kana mitambo), uye mazhinji haawani munzvimbo dzose.
Heino mhedziso yeiyi inowanzovhiringidza teknolojia.
Kwete Mafoni Mavose Akaenzana:
Mutengi wako angapa hurukuro yepamusoro-data, asi kwete mafoni ayo ose anokwanisa kuwana mavhisi ekurumidza. Ndezvipi zvimwe zvipfeko-izvo zvakagadzirirwa chipset zvakanaka mukati-zvinogona kudaro.
Kushandurwa kwe 3G is mobile broadband network, inopa dhiyabhorosi kudarika 144 kilobits pamusi wechipiri (Kbps). Kana uchienzanisa, kuiswa kweInternet-up network pa kombiyuta inowanzopa kasi inenge 56 Kbps. Kana iwe wakambogara uye wakamirira peji yeWebhu kuti udzivirire pamusoro pekubatanidza-dial-up, unoziva kuti chinononoka sei.
3G mitambo inogona kupa mhanho ye 3.1 megabits nechipiri (Mbps) kana kupfuura; iyo inopfurikidza nepamhanho inopiwa ne cable cable.
Mukushandiswa kwezuva nezuva, zvisinei, kasiro chaiyo yehutano hwe 3G ichasiyana. Zvinhu zvakadai sesimba remashoko, nzvimbo yako, uye network network zvinotanga kuitika.
T-Mobile Lags Pakupedzisira:
Pari zvino, T-Mobile inotsigira 2.5G EDGE network. Mutakuri wacho anoronga kuunza hutano hwe 3G, nekutsigirwa neHSDPA yepamusoro-soro, gare gare iri zhizha, zvakadaro. Ramba uchitarisa.
AT & T's High-Speed Service:
AT & T inopa nhatu nhatu dze "high-speed" data: EDGE, UMTS, uye HSDPA.
IWEDGE network , iyo inotengeswa nedhina yakatsigirwa ne iPhone yezera rekutanga, haisi yechokwadi ye 3G data network. Inowanzotumidzwa sehutano hwe 2.5G, nehanho dzisingapfuuri 200 Kbps.
Basa reMMTS rinokurumidza kufamba 200 Kbps kusvika ku 400 Kbps, uye inogona kubuda pamusoro pe2 Mbps. Iko basa rechokwadi re 3G riri kukurumidza kupfuura iyo yeWEDGE network.
Sprint Nextel uye Verizon Wireless:
Sprint Nextel uye Verizon Wireless vose vanotsigira network EV-DO. EV-DO inopfupika neEvolution-Data Yakagadziridzwa uye dzimwe nguva inopfupiswa seEvDO kana EVDO. EV-DO inoratidzirwa kupa zvinomhanya kubva 400 Kbps kusvika 700 Kbps; semamwe mawekiti e 3G, kupera kwechokwadi kwakasiyana.
Kusiyana pakati pebasa reEV-DO rakapiwa neSprint Nextel uye iro rakapiwa neVerizon Wireless harusi. Nhanho dzinofananidzwa, asi mumwe nomumwe anotakura anopa kugovera munzvimbo dzakasiyana.
Ona Sprint's Coverage Map neVerizon mapeji anovhara kuti uwane mamwe mashoko pamusoro pekuwanikwa kweterevhizheni.
HSDPA ndiyo inonyanya kukurumidza mitambo. Inokurumidza zvokuti inowanzozonzi network yaGGG. AT & T inoti network inogona kukurumidza kufamba 3.6 Mbps kusvika ku14.4 Mbps. Ichokwadi-nyika inowedzera kazhinji inononoka kudarika iyo, asi HSDPA ichiri yakakura kwazvo network. AT & T inotaurawo kuti network yayo icharova nekukwira kwema 20 Mbps muna 2009.
Kuti uwane mamwe mashoko pamusoro pekuwanikidzwa kwemitambo, chengetera mapepa ekutenderera AT & T.
