Hiki i nā poʻe smartphones ke komo i ka pūnaewele, akāʻaʻole hiki i nā mea a pau ke hana pēlā ma ka wiki hoʻokahi. Hiki i kekahi mau kelepona ke hoʻouna mai kahi pae ai kahi pūnaewele, e hoʻoukaʻana i nā faila i ke kani, akāʻo nā mea'ē aʻe e hāʻawi i nā wiki iʻoi aku ka wikiwiki ma mua o kahi pilina o nā loina kahiko.
ʻO ka'ōpili o Apple,ʻaʻole i hiki ke komo i kahi pūnaewele HSDPAʻo AT & T; Wahi a Apple,ʻaʻole e hoʻokomo i ke kākoʻo no ka HSDPA no ka mea ua kahakaha ka mana o ka chipset pono, e ho'ēmi ana i ke ola o ka pila.
Inā pili iāʻoe kaʻoihanaʻike wikiō nui, e hoʻomaopopo i ka leka uila āu e makemake nei e kākoʻo i kahi kōnae 3G. A hoʻomanaʻo e nīnau inā hiki iāʻoe ke ho'āʻo i ke kelepona a me ke 3G i mua o ka hanaʻana i kahi kuʻikahi lōʻihi, a hoʻihoʻi mai ināʻaʻoleʻoe e pōʻino i kāna hana. Hoʻomaopopo: E loli paha nā puka pololei.
Pehea e hiki ai iāʻoe ke hōʻoia e hāʻawi wikiwiki aku kāu pūnaewele i ka pūnaewele pūnaewele? ʻO kekahi o nā mea nui loa,ʻo ia ka pūnaeweleʻikepili e kākoʻo ana i kāu pūnaewele-a me ka pūnaewele i hāʻawiʻia e kāu mea kikowaena. ʻO ka 3G, aʻekolu paha o ka hanauna, e hāʻawi ka pūnaeweleʻikepili i nā wiki wikiwiki. ʻAʻole i hoʻokumuʻia nā pūnaewele 3G a pau, akā naʻe. Hiki i kēlā me kēia mea kelepona pūnaewele hāʻawi i konaʻili pūnaewele (aiʻole nāʻupena), a nuiʻole ka loaʻaʻana i nā wahi a pau.
Eia kekahi hiʻohiʻona o kēiaʻenehana maʻalahi pinepine.
ʻAʻole Kūpono nā Phones a pau:
Hiki i kāu kaukawe ke hāʻawi i kahi pūnaeweleʻikepili lōʻihi, akā,ʻaʻole hiki i kona mau kelepona ke komo i kēia mau lawelawe wikiwiki. ʻO kekahi mau pūnaewele wale nō-ʻo nā mea i hoʻokomo i ka mākau pono ma loko-hiki iā lākou ke hana pela.
ʻO ka'unga 3G he polokalamu kelepona pūnaewele pūnaewele, e hāʻawi ana i nā pūnaeweleʻikepili he 144 kilobits ma kēlā me kēia (Kbps). No ka hoʻohālikelike, hāʻawi pinepineʻia ka pūnaewele pūnaewele e pili ana i ka lolouila i nā piʻi o 56 Kbps. Ināʻoe i noho a kali i kahi pūnaewele pūnaewele e kiʻi ma luna o kahi hui pūnaewele,ʻikeʻoe i ka lohi o ia.
Hiki i nā kikowaena 3G ke hāʻawi i nā piʻi o 3.1 megabits ma kēlā me kēia (Mbps) aʻoi aku paha; aia ia me nā ikaika i hāʻawiʻia e nā modems cable.
I kēia lā, e hoʻohanaʻia ka wikiwiki o ka pūnaewele 3G. ʻO nā mea e like me ka ikaika hōʻailona, kou wahi, a me nā kaʻa pūnaewele a pau i pāʻani.
T-Mobile Lags Behind:
I kēia manawa, kākoʻoʻo T-Mobile i ka 2.5G EDGE network. Hoʻolālā ka mea lawe kālā e hoʻokumu i kahi 3G pūnaewele, me ke kākoʻo no ka lawelawe HSDPA kiʻekiʻe, ma hope o kēia kauwela. E hoʻomanaʻo.
ʻO ka lawelawe kiʻekiʻe kiʻekiʻe o AT & T:
E hāʻawi anaʻo AT & T i nā'enepili'ilipili "ʻekolu" nui: EDGE, UMTS, a me HSDPA.
ʻO ka EDGE pūnaewele ,ʻo ia ka pūnaeweleʻikepili i kākoʻoʻia e ka iPhone-mua,ʻaʻoleʻo iaʻo kahi o kaʻikepili 3G pono. Hoʻohui pinepineʻiaʻo ia me he 2.5G pūnaewele, me nā wikiwikiʻaʻole iʻoi aʻe i 200 Kbps.
Hāʻawi ka lawelawe UMTS i nā kaha o 200 Kbps a 400 Kbps, me ka hiki ke piʻi i waho ma kahi o 2 Mbps. He 3G lawelaweʻoiaʻiʻo me nā wiki iʻoi aku kaʻoi aku o kaʻoihana EDGE.
Ka hopena Nextel a me Verizon Wireless:
Hoʻopili ka Spread Nextel a me Verizon Wireless i kaʻenehana EV-DO. He pōkoleʻo EV-DO no ka hoʻolālāʻana i ka Evolution-Data a ke hoʻopauʻia kekahi manawa e like me EvDO a iʻole EVDO. Hoʻomanaʻoʻiaʻo EV-DO e hāʻawi i nā piʻi mai 400 Kbps a 700 Kbps; e like me me nā 3G pūnaewele'ē aʻe, nāʻano likeʻole e loli.
ʻO kaʻokoʻa ma waena o ka lawelawe EV-DO i hāʻawiʻia e Sprint Nextel a i hāʻawiʻia e Verizon Wireless he mea liʻiliʻi. Hoʻohālikelike nā kūlana, akāʻo kēlā me kēia ukana e hāʻawi ana i nā mea likeʻole.
Eʻike i ka palapala a Sprint's Coverage a me ka palapala hoʻolālāʻo Verizon no kaʻike hou aku e pili ana i ka'ikenaeke pūnaewele.
ʻO ka HSDPA ka wikiwiki o ka pūnaewele wikiwiki. ʻO ia keʻano wikiwiki i kapaʻia he inoaʻo 3.5G. P & A i kaʻenehana hiki ke paʻi i kahi o 3.6 Mbps i ka 14.4 Mbps. ʻO ka nui o ka wikiwiki o ka honua eʻoi aku ka māmā o ia, akāʻo ka HSDPA he pūnaewele nui wikiwiki. Wahi aʻA & T hoʻi e paʻi ana kāna pūnaewele i nā kaha o 20 Mbps i 2009.
No ka 'ike hou aku e pili ana i ka loaʻa' ana o kaʻenehana, e nānā i ka mahele o AT & T.
