Me pēhea te ki te whakapiki ake i te tere pouwhanga paerewa 3G CDMA?

Nga◊i ia, i runga i a ringaringa ngohengohe, te reira te wā ki tere tiketike, me tariffs iti mō te whai wāhi Ipurangi. Na ka waiho tangata uru miharo ki te whatunga ao ka kīia e o runga 100 megabits, rawa i roto i nga pa nui. Heoi, meatia tenei katoa e ki te awhina o ngā taura: rārangi optical pukupuku waea tikanga ranei - ko te taua te faufaa. Otiia i nga tangata o nga takiwa mamao me kainga te wahi i reira he kahore kaiwhakarato raina taura ki te hono ki te Ipurangi ki te hei ihirangi tuku ngā ahokore. He nui teitei ratou reiti me ko raro te tere. Hei tauira, tetahi o te tino matatau hangarau CDMA Rev.B takahi taea te tere o te whai wāhi ki te 14 anake megabits e tangata -. "Nonanahi" 'Oku mahinongofua e i roto i taua tikanga, e hiahia ana ia kaiwhakamahi o te Internet ahokore ki te mohio me pehea ki te whakapiki ake i te tere o te pouwhanga 3G.

Ko te aha tatou e kōrero i teie mahana, engari hei tauira, whakaaro CDMA EVDO pouwhanga. Ahakoa i reira e rave rahi putanga CDMA, rere matua he auau kawe, tuku ki roto i tenei pepa, e hāngai ana i runga i te huarahi mo te tetahi kaiwhakamahi e hiahia ana ki te whakapiki ake i te tere o te pouwhanga 3G.

Faaineine i te mau uiraa, he iti pa i runga i te turanga ariā. Tuatahi, i tetahi kaiwhakarato i roto i te tāke whakaahuatanga tohu te tere o te whai wāhi ki te whatunga, hei tauira, ki runga ki te 3.1 Mb / s. Kaiwhakamahi tuatahi hono ki te Ipurangi ahokore, maha fifili aha e kore e o 3.1, engari ara 2 megabit taea ki te whakatutuki i tino onge. Kahore he haavare: te kuhimua "Up" ko tino tika, aue. Heoi, kahore ārai ki mahino te take, me te matau e founga ki te whakapiki ake i te tere o te pouwhanga 3G ki te taea mōrahi, te mea e taea e te reira ki te tangata e homai nei i te whakaaro taua.

Tuarua, ko te tere o te Internet ahokore kore e eu: reira "e taritari" i haora ki haora. Ia teihana pourewa he auau pūmau o ona ake hongere kōrero, ahakoa tino nui. Kaiohauru, hono i te wāhi etahi i roto i te wa, wehe tahi tenei auau rite karaka. Nä, ko te whakahoki tuatahi te pātai o te pehea, ki te whakapiki ake i te tere pouwhanga 3G, CDMA ko ki te whakamahi i te pouwhanga i roto i te rohe kapinga o te teihana iti utaina i te wa e tika. I roto i te mau parau te tahi atu, ka waiho teitei i roto i ngā wāhi i te auau ki iti taupori kiato e toru i roto i te ata i te i roto i te pokapū o te pa nui i roto i te wa mahi.

Well, kia waiho anake o te ariā me te tohu he aha a te wahi e hiahia ana koe ki te "takawiri" ki te whakatutuki i ngā hua tino. Me pēhea te ki te tere ake 3G pouwhanga? Easy! Ua itehia e, e tauira rerekē o ngā pouwhanga whakaatu reiti rerekē, ceteris paribus. Ko te whakatinanatanga o te kōwae transceiver, whakanohonga hāneanea o wāhanga ā-nui whakaawe te hua. Hei tauira, te tahi mau tauira i muri i 2-3 haora o te mahi tino pupū ake me te tīmata ki te kore, e ko tonu kitea i runga i te tere tūtohi. Tirohia te mahi pouwhanga - kia waiho reira mahana, engari e kore e wera.

Tetahi pouwhanga USB 3G pau tetahi tauranga o nāianei. Ano, Ko reira te tikanga 500 mA. Hoki te paerewa USB 2.0, ko tika te rohe tenei. Na reira, ki te ki te kotahi USB hub hono te pouwhanga me tetahi atu pūrere, he kore nui te mana e pā te mahi. Kua noho koe neke atu i te hawhe o nga tūhono USB? I roto i tenei take, e hiahia ana koe ki te hoko i te tari ä-hub ki te supply mana waho. Tērā: ko reira whakaaetia ki te hono i te pouwhanga mā Y-taura. E ia e toru mutu: e rua ngā i roto i te tūhono i runga i te rorohiko, i te toru o haere ki te pouwhanga.

Ki te koe tonu e kore e matau me pehea ki te whakapiki ake i te tere o te pouwhanga 3G, mahi radically: tāuta he pūihi waho. Ko te teitei i e taea te tiki e koe i te reira ki runga, tauwhāiti te taura -. E kore e nui ake te roa 10 m Ko kore whakaora utu, hoko kounga i runga i te taura! E te ara, e kore e wareware ki te takoto i te pūihi ki te teihana turanga.

He pai ki te whakahou i te taraiwa pouwhanga me arotau te hononga i te hōtaka motuhake hoki reira.
