HSDPA - he aha te mea te reira? i akina atu HSDPA whakaweto

Ko te hangarau o tiketike-tere pākete uru mā te hongere tāuru i whakatapua - na tu HSDPA. He aha te mea te reira me aha e nga painga o tenei hōputu tenei ra mohio anake te maha iti o ngā kaiwhakamahi, engari ko te tino noa te hononga i teie mahana. A, ki te tika te tau i ma'iri a'e nei, te nuinga o ngā tohunga anake whakaaro e pā ana ki te mea he reira me he aha te ahua o te heke mai taea tatari mo tenei hōputu, engari inaianei kei te kaha te whakamahi i kaiohauru noa he pūhui taua, tohaina nei te rite te wha whakatupuranga hononga 4G «."

Aha te hiahiatia reira?

Te āhuatanga whānui i roto i te parae o whatunga tuatoru-whakatupuranga ko, ki te hoatu i te reira oangé, pe'ape'ao, me e ko te take matua he aha e hiahia i roto i te hononga HSDPA maha kaiwhakarato ratonga. He aha te mea te reira - e kore e ngā kaiwhakamahi mohio, engari 4G whakarāpopototanga kukume atu 3G, no te mea kei te mohio a te reira rite te tere me te whai hua.

e mohio ana torutoru iwi e i roto i te tīmatanga o te 2000 i roto i Europe CDMA me HSDPA ngā kua hoatu neke atu i te $ 100 piriona. hoki noa ki te tiki i te raihana mo te tuatoru-whakatupuranga deployments whatunga. Ko te kupu, ko te plurality o kamupene pūtau nga nama arorangi, kia kia mutu ratou ake mau noa. I muri i te katoa, te meka ko e tae noa tata, te mākete i whānui, i reira nga kahore 3G-waea, a reira kahore he ara ki te waea i te maha e hiahiatia ana o kaiohauru tēnei wā, e pai tukua ki tangohia te haumi.

HSDPA - te Internet pūkoro i teie mahana

O te akoranga, tata anga reira whanaketanga kaha i roto i te hunga kamupene, e i tetahi wa haumi i roto i te ao 3G, me te HSDPA. He aha te mea te reira? Tenei tukua he maha nui o waea, i roto i nei ki te whai wāhi te whakamahi 3G hei hononga Ipurangi hohe, me te tukatuka tino nohopuku o ngā mōhiohio mā te whatunga. I roto i to tatou wa kei te tata rawa nga waea pūkoro hou, i tukua i roto i te tau torutoru whakamutunga, i runga i te pūtake whakahauanga te ki te uru ki te 3G. Oia mau, i roto i te ubiquity o te Internet e, eita roa ia te whakamahi i te pūhui tawhito puhoi atu atu i te tere tino iti.

Ko wai ka whakamahi i te reira?

I roto i te mākete pūkoro ake me te ake maha timata ki te puta ngā pūrere e whai, i roto i te tua ki 3G, kua tautokona hoki hangarau HSDPA. He aha te mea te reira me aha e nga painga o tenei hangarau mo GPRS, ngā kaiwhakamahi matatau maha kahore e mohio ui na maha iwi te pātai arorau: te mea utu hoko i te waea, a ka waiho ranei reira atu hua i roto i ngā o te whakauru i te Internet.

He tokomaha hianga i whakaaro tenei hangarau rite te wā tauwhirowhiro ki te whatunga nui-tere ka karanga 4G, mai te pai mahi te whatunga i roto i ngā āhuatanga tāone, me te ngāwari taea te whakamahi roto.

He aha e ona painga?

Tenei hangarau taea ki a koe te mahi te wā kotahi i te maha o ngā kaiwhakamahi i roto i te whakamahi o te hangarau multiplexing ki te wā, me te tohatoha waehere. HSDPA parau tumu mahi matua - atu raraunga, tere teitei. Ko te aha hanga tenei kupenga kotahi o te tika te nuinga ki te hapai i te waka taratahi mō ngā kaiwhakamahi maha.

He nga mea timatanga e whai ake nei i te pūtake o tenei hangarau:

• kaupapa urutau waehere me QPSK puoro me 16 QAM.
• kawa tānga motuhake.
• tāutu tonu o te matua waka i runga i te Kōpuku B mā te whakamahi i te kawa tere MAC-tiketike.

Tenei hangarau whakawhiti i ngā ratonga rongorau matatau ki te taumata hou katoa, tuku kaiohauru ki te whakamahi i te hononga nui tere. Ko e tika ana ki te meka e, whakawhetai ki te uara tiketike o te tuku auau mōhiohio, ngā whakaroa iti tenei, engari faarahi tenei te rōrahi o ngā raraunga tonoa.

Pehea te whakamahia i te reira?

Whakamārama me te mōhiohio HSDPA whakakitea te whakaaro matua o te whatunga - ko ki te whakarite i te mōrahi whakamahi pai o te aratūātea irirangi i roto i te mahi o ngā ratonga, e hoatu ara ki te hiahia mo te raraunga auau whakawhitinga tino nui o ngā kaiwhakamahi i runga i takere downlink, pērā i te whai wāhi ipurangi, me te kōnae tikiake.

I whakaurua tuatahi te whatunga mo te kaiwhakamahi wā tuatahi i roto i te paerewa 3GPP, tuarima te putanga. Takahi, he te rahi pūtau tonu o ka te whakamahi i te mea e taea tenei hangarau ki te whakarato i te tere o e pā ana ki 10 Mbit / s. uara tere tino nui i roto i taua rohe ko te 14.4 Mbit / s, engari mau whakatutuki tenei tere he tata e taea.

whanaketanga muri o paerewa 3GPP whakahaua ki ake i te rohe tere, ai e waiho reira taea ki te titau e runga i te wā ka timata te reira ki te tae 20-30 Mbit / s. Hei āwhina ki te whakatutuki i ēnei uara o tere kia mimo āhuatanga, me te tikanga hou o te whakamahi i ngā huānga pūihi.

Kia whakamahi i ahau i te reira?

Na i runga i te taumata mahi mohio tere o runga ki te 42 Mbit / s, a i roto i te ariā, ka e kia kitea reira te tuku 11 o te paerewa 3GPP, ka kua kia āhua 337 Mbit / s te tere. Ki te rā, tonu i runga i te whatunga UMTS HSDPA 3G, engari te tere tonu rau nui ki te kia hiahiatia, ahakoa hoki ngā pūrere pūkoro ko reira nui atu i manakohia.

Nā ki te raraunga auau whakawhiti pai, hononga pūmau kounga teitei, me te mahi tata ore o tenei hōputu rawa i taea te huri i te kanohi o rerekē kaiwhakamahi gadget e ko te toru o whakatupuranga pūhui. I te wa ano maha kitea etahi ngā takoha HSDPA whakaweto, e taea e tino kino.

WCDMA HSDPA ranei?

ngā whakaiti te horo 3G he maha nui o hangarau e ngā tahi i raro i te taitara o "te toru whakatupuranga pūhui." I roto i ngā, i te tino noa i tawhiti ko te WCDMA me HSDPA, e huna i raro i te whānuitanga o ngā hangarau kōrero, e pā ana tino ki te toru o nga whakatupuranga, engari he tino rerekē.

Ki te whakaaro tatou me whakarite enei hangarau, ko atu matatau te HSDPA, a ko reira kore maere, mai i whakawhanakehia ai ahua muri whakaritea ki WCDMA me taea hoki te hononga tere teitei. Ko te kupu, ki te whakarato i te hangarau hou te tere o kaua e nui ake 3.6 Mpiah, i HSDPA i ariā me taea e te mea katoa ki runga ki e pā ana ki 42 Mbit / s, ahakoa i roto i te mahi taua uara e, o te akoranga, i matara atu i te taua. Me kï reira e kia tuku te hononga o tenei hōputu ki noa HSPA, e tohu ana i te uniana o rua hōputu - HSUPA me HSDPA. He aha te mea HSUPA ko HSDPA, i roto i tenei putanga? Tenei whakaterenga tukutahi o hononga putaatu me taumai.

I te mea pai?

I roto i te mahi, uaua ki te whiriwhiri he aha te mea pai tonu, me e taea e koe te pōti mo te WCDMA, HSDPA ipurangi mo e, i runga i te āhuatanga me te hiahia rānei. Ko te kōwhiringa i waenganui i taua whatunga maha hanga nga rangatira tautoko i te 3G-pouwhanga rua noa hōputu, me te hono ki a ia kaiwhakahaere. Ka taea e Root whakaata taua iwi e tika ana ki te pūmautanga rerekē paninga aroaro pahuhu ranei. Me kï reira e te tahi mau taime i reira e te hunga āhuatanga i reira e taea te whakamahi i te fare i taua e te paerewa e rua kōrero, i roto i te tahi atu i te ruma whakamahia te WCDMA anake. kia hoki kia mea te reira e taea te whakawhitinga auau kia tino i roto i te kaupapa e rapua e koe i te hononga tonu, a kia hoki te whakaaro te reira.
