I te mea pai - H- 3G-ipurangi ranei? kōwhiri

whakatupuranga o teie mahana he pakeke ki te whakaaro, engari kotahi i mau nga waea waea, e kore smartphones. Ka taea e te hanga ratou waeatanga, kore ake. I te wa ano i ratou iti, me te hāngai i roto i to koutou te pute, engari ki enei gadgets, ko e taea ki te tango i pikitia, me te faaite ia ratou. O te akoranga, ko e taea ki te hanga ira uru waea, e kore e ki te whakahua i te maha atu ngā mahi.

Ko tenei kua tata haere te waea, i reira he smartphones anake. I teie mahana, ki te whakawhanake i nui-tere whatunga ahokore muri-whakatupuranga, i te mea he aha te kaiwhakamahi toharite te rota o mea mea rawa huanane tonu te ao. Hei tauira, maha tamata kaiwhakamahi ki te kitea i roto i te mea te mea pai: H 3G ranei? Ko te auau raraunga i roto i enei whatunga, me ētahi atu Ko te waihanga rawa o taua pātai he heahea, a kahore e te tangata matau te mea ki te ui.

He aha te tikanga a koutou ipurangi 3G, E, H?

tu G mō te whakatupuranga (To'u). Tenei te tikanga e ka mea nga kaihanga 4G, e kōrero ratou ki te whatunga ahokore, e hāngai ana nei i runga i te wha-whakatupuranga hangarau. Heoi, i te wā "whakatupuranga" i roto i te tahi mau tikanga, puputu'u kaiwhakamahi noa. Na reira, me tamata tatou ki te matau tenei katoa.

Here E ko H - ko te raraunga hangarau tuku, e no ki rerekē whakatupuranga. Ko titau te whakamārama āmiki tenei.

1G

Ka meinga tuatahi-whakatupuranga hangarau waea pūkoro te hua papatipu. I runga i te pūtake o tenei whakatupuranga kua riro te tino rongonui hangarau whatunga TACS me NMT. whakamahia Tuatahi i roto i te US, te tuarua - i roto i Europe. Na ara te whakaaro kahore tetahi ki te whakarato ratonga raraunga. I taua wa i reira nga pūnaha tairitenga e taea ai te reo waea, me te whakarato i etahi atu āhuatanga.

Ko te auau whakawhiti raraunga o enei hangarau kua iti, me te utu o te meneti kotahi i utu he rota o te moni, kia taea te whakaaro te aroaro o te waea pūkoro te papai. Heoi, e kore te mea roa i roto i te haere mai i te whanaketanga o te whatunga. Hohoro i reira i te rua-whakatupuranga whatunga 2G.

2G me 2.5G

Ko te whanaketanga o te whakatupuranga tuarua taka i te timatanga o te 90. Whatunga i runga i taua mea kua oti pai tiakina, hohoro atu, ka pai ake te kounga ororongo. tautoko ētahi whatunga te tuku o ngā karere poto (SMS). Na reira, miharo kahore tetahi e H pai 3G ranei. Ki te toru o nga whakatupuranga i ano ki te whakawhanake.

I te 1997 ka puta ia GPRS, a ko reira he wāhi koki i roto i te hītori o te whanaketanga pūtau. Ko he revolution tūturu, no te mea kua whakaekea te hangarau te whai wāhi ki te whatunga GSM raraunga tamau i te tere teitei.

Heoi, e kore i te reira ano he toru o whakatupuranga tonu-parirau. Ko te paerewa tuatahi, i whakaaetia te whakatakotoranga ki tonu o 3G, ko te IMT-2000. whakarato te reira i auau raraunga o runga ki te 2 megabits ia rua.

ipurangi Mobile 3G: E, H, G

I tua atu ki teitei auau raraunga, te whakaaro te paerewa whakawhiti tere i te tuarua ki te toru o nga kupenga whakatupuranga. Ki tenei mutunga, kua whiriwhiri te nuinga o ngā GSM UMTS paerewa.

I tenei wa, whānui whakawhanakehia paerewa Mata. I hapu tuatahi reira hei ara ngāwari ki te kotēhia i te whakatupuranga 2.5G mōrahi ki te haumi moni nui i roto i te whanaketanga faufaa ore. I runga i te waea ki e taea te whiwhi tautoko mō te paerewa Mata auau whakawhiti raraunga rua rite tiketike rite i roto i te paerewa GPRS.

E te ara, ko reira uaua ki tenei paerewa, no te mea kotahi ko reira mārama te wahi ki te hoatu ai. He maha ngā tohunga huanga reira ki 2.75G whakatupuranga.

I muri i te 10 tau o te whatunga UMTS riro te whakamohoa i roto i te puka o hangarau HSDPA me HSUPA e tere te waka taumai me te matenga kua tino nui haere ki. A, ki te whakaaturia koutou waea te i te tihi o te pukapuka H, ka tikanga te reira e te tuku HSDPA paerewa kaha HSUPA ranei. Otiia e kore e taea e matou te mea i te mea pai: H 3G ranei, no te mea H (HSDPA) he tino he 3G hangarau (whatunga raraunga tuatoru-whakatupuranga). Na reira, e kore te iwi maha pātai e tino arorau. 3G tere ipurangi ka kia rite, me te H, engari ka taea e etahi waea huri te pukapuka i runga i runga o te pae whakaatu e. Otiia e kore e mau te huri i te reira, a i roto i rua wā te whakamahi i te whatunga raraunga 3G.

Otiia ara i tenei ra i roto i te tahi mau pa kainga ina te hono te waea ki te whatunga ranei, ka taea e kite koe i te G reta E ranei i te tihi o te mata. Tenei te tikanga e whakamahia mata me GPRS paerewa, e ko te whakatupuranga whatunga 2G 2.75G ranei. Ki te koe e pera, i roto i tenei take, koutou e kore e mea faufaa, he aha te mea pai: H 3G ranei, i roto i te meka āhua rite pukapuka G ko E whakaatu pehea ki te hono ki te whatunga tuarua-whakatupuranga.

4G

He whakatakotoranga ITM-Arā e tautuhi ana i te paerewa mo te wha whakatupuranga whatunga 4G. tautuhi ana te tuhinga i te auau raraunga taumai - 1 Gbit / s, me mo nga terminals 100 Mbit / hekona mō smartphones. Faahiahia, he reira 500 me 250 wa tere atu i he whakawhiti raraunga i roto i te whatunga matatau ITM-2000. Ēnei tere ara nui hononga tika ki aunui.

nui te reira i te wāhi nui i roto i ngā wāhi tuawhenua pērā hangarau, rite atu utu-whai hua ki te hanga i te 4G-teihana i pai whakarato i tētahi hononga kaiohauru katoa i roto i te pūtoro o te 10 km. Te kore e whai i te reira ki te hanga i tētahi "paraikete" o te muka.

Ko te mea ia tapao e ko na ohie te whakatakotoranga ITM-Arā, e i teie mahana i reira he tata kahore paerewa e pai te whakatau ia ratou. Ko, i reira he kahore whatunga 4G tonu-parirau. Ae, WiMAX me hangarau LTE paerewa lau ōkawa te whatunga whakatupuranga tuawha, engari he pono e kore te mea te reira 100%. Ko te meka e te whakamahia te whatunga, ahakoa kaupapa multiplexing hou, me te 100% o ratou hōkaiipurangi mō te whakawhiti raraunga wāhi, he tonu e kore ake te tere ki te paerewa e kua whakaahuatia i roto i te ngā whakahuatia i runga ake. I roto i te ariā, te hangarau LTE tā auau whakawhiti raraunga o 100 Mbit / s, he tino mīharo. Heoi, i roto i te mahi he reira nui kino: ko te nuinga te tere whatunga iti iho i te 30 Mpiah. O te akoranga, ara 30 Mbit / s - Ko te tino nohopuku tenei, ko te meka ko e kore e tenei auau hāngai ki te whakatakotoranga. Na reira, e kore e taea te whakaaro te paerewa LTE te wha-whakatupuranga hangarau. Ki te rā i reira he kore hangarau e e whakatau whakaritenga ITM-Arā.

3G 4G pai?

e kore noa kauwhautia ētahi kawe US te whakawhitinga ki te wha whakatupuranga paerewa. noho ratou i runga i te whatunga 3G me whakapai ake i te reira. Hei tauira, kei te whakahou operator T-Mobile te whatunga 3G, e ngana ana ki te whakapai ake i te HSPA paerewa ki HSPA +. Heoi, e kore e ara e pa ia te whatunga wha-whakatupuranga paerewa. hanga tenei tikanga, no te mea kua pai ake te paerewa 3G ki te rohe, he taea ano reira ki te whakatutuki tere tiketike. mau ka te HSPA + taua whakarato te hōkaiipurangi kaitango ki te puta haere o te 42 Mbit / s.
I roto i tenei whakaaro, operator T-Mobile radically reinterprets aha te mea mau te paerewa 4G me te Internet tere. 3G H ranei i roto i te waea e taea tikanga he auau whakawhiti raraunga ake ki te 42 Mbit ia tuarua, engari kia tae noa reira anake pā ki kaiohauru o T-Mobile.

Ka rite ki tu mea i roto i te mooni?

Te āhua ki te kia e pai te whakawhanakehia he whatunga tuatoru-whakatupuranga, me whai ara i roto i te uru pa nui ki 4G Ipurangi, engari he kino te mooni. I roto i te rohe maha o Russia me i whānui puta noa i Ukraine reira he kore 4G kapinga. Ae reira 4G, ara, ki te te whakatupuranga 3G o painga whakawhanakehia. mai te reira i ki te meka i roto i maha hoki nga kainga me nga pa i runga i smartphones āhua rite pukapuka puta E ina hono koe ki te Internet. Ka rite ki a koutou e taea e te kite i te tuhinga i runga, e pā ana mata ki te whakatupuranga whatunga 2.5G me "taka poto" i mua i ara tuatoru-whakatupuranga whatunga.

He aha Ipurangi pai: 3G H ranei?

I te tīmatanga tikanga tenei rauemi i ki te āwhina i te kaiohauru o ngā pūkoro ki te matau i te whakatupuranga o whatunga, rite ki katoa o enei paerewa kōrero e taea e huanane. mai te reira i ki te meka e e ngana ana ngā kaiwhakamahi ki te whakarite i te tere i waenganui i te toru o whakatupuranga (3G) whatunga me te hangarau HSPA, e tika pā ana ki te toru o nga kupenga whakatupuranga. Pakeke e korero ana, H - ko te 3G tenei.
