He aha te mea he waea 3G, me pehea e whai hua i te reira ia tatou

ora tatou i me te korikori ai i roto i te ao o te mōhiohio rere, hanga pinepine o waea waea, he kore tonu i roto i te tari i te kāinga ranei, i roto i tetahi ara ranei tetahi ka fehangahangai ki te paerewa 3G (acronym mo te Ingarihi.

Ki ngā ratonga taketake mō te 3G-whatunga hopohopo rite kōrero reo me raraunga. Critical o te whānuitanga o ngā ratonga i te tūmataiti iti, mahara te paerewa o mua, e kore e matau he aha te mea 3G waea i tenei ra. whakarato teie mahana tuku raraunga kōrero rite te whānuitanga pakihi i te tere nui (e-mēra, hui ataata, uru mamao ki pātengi raraunga, te whakahaere o te pēke pūkete), me ngā ngākau nuitanga whaiaro (kēmu, whatunga pāpori, ngā pūnaha rongorau, hoko ipurangi). rerekē inversely auau te tuku ki te tere o te ahanoa. I roto i te take o te kimi i roto i te wahi - 2048 kbit / s, i te tere ko te 3km / h - 348 kbit / s, 120 km / h - 144 kbit / s. Popular ki ngā kaiwhakamahi pārekareka ki pūkoro Ipurangi mutunga, e tuku ratou i te rave'a mo te pūmau utu ā-marama te uru mutunga ki te whatunga ao.

Ko 3G ipurangi - he aha te mea te reira? Ehara i anake waea pūkoro. Ki te whai koe i te PC, netbook, pukatuhi, ka hono ki te hononga Wi-Fi e hiahia ana koe he 3G-pouwhanga. Ko te pūkenga tino ko te USB-pouwhanga, e hono hāngai ki te USB-tauranga o te rorohiko. I tua atu ko reira taatou taea ExpressCard, PCMCIA. Hoki muri pūrongo pono fariiraa tohu kōwhiringa kounga mau ia vai devaysa tona whānuitanga auau, te tere tohu tuku. Well, ki te he tata te kaiwhakarato pourewa tata. A, no te e whakarato i te tawhiti o te 10-50 km te mahi pouwhanga pūmau hāngū 3G-pūihi. Ā-ope reira ki 5-10 waeoro, engari i ētahi wā e hiahia ana te waho, atu kaha. Ki te mahi i tenei, kia hoki kia koutou whai hua pouara 3G Wi-Fi. Me mōhio e mo te toru auau here 3G Ipurangi: 450, 800, 2100 MHz - pouwhanga hāngai tīpakohia ki te pūihi.

Tere whakawhanake mākete o smartphones hou me kōrero. Tenei "matarohia" Hupa, whakaatu e tenei waea 3G. e, i roto i te tua ki te whakatinanatanga o te reo kōrero, e rite rawa ratou ki hanga-i roto i 3G pouwhanga, mau tonu kōrero ki te WWW. I runga i te mata tapahi o te ahunga whakamua, he HTC me Samsung (pūhara Android) ngā pūrere me Apple (pūnaha whakahaere iOS).

Na whiwhi rongonui i roto i ngā kaiwhakamahi o ngā pūrere pūkoro ki mata nui - papa. kia Kei tēnei pūrere he pouwhanga 3G ngātahi (tūtohutia e te, rawa, ki te te kaiwhakanao - Haina) - ki te kore, ka hiahia koe ki te hoko i te reira. Ko reira taea e motuhake hokona "kore" atekōkiri pouwhanga.
