I-CDMA amafoni - kuyini? I-CDMA + GSM-dual-amafoni

Kulesi sihloko kuzoxoxwa CDMA handsets, onjani Isobho nalapho ngaphandle kwalo nje akakwazi ukukwenza. Kuzoba futhi anikezwe izici onobuhle yangempela kanye nezincomo mayelana ukuthenga kwabo.

amazinga zokuxhumana mobile ezimbili ezinkulu

Kuze kube manje, lo kabanzi kunazo kumadivayisi eselula yemigomo emibili: i-GSM ne CDMA. Ngamunye wabo kuyinto ejwayelekile digital. Kodwa nakhu ukudluliswa isignali ngamunye lezi zimo Kwenziwa ehlukile. Esimweni sokuqala, ibanga lokuvama ihlukaniswe yaba izingxenye, ingxoxo ngayinye ithatha ingxenye encane nje kuphela bohlu. Esimeni sesibili, esephepheni ivumela zokubhalisa ukusebenzisa zonke umthombo omsakazo. Ngenxa yalokho, esimweni esinjalo, ikhwalithi ikholi ngcono kakhulu. Kodwa nakhu kwande namuhla ukuze uthole amanethiwekhi eselula yohlobo sokuqala. Le ndinganiso laqanjwa ngisemncane kakhulu futhi ngesikhathi isimemezelo CDMA ukwenza isivele ngenkuthalo esetshenziswa. Manje ukuze uphendule lo mbuzo: «I-CDMA Amafoni - siyini lesi Isobho ezinjalo" Lezi amadivayisi ziqondiswa ukuze isetshenziswe? Mobile-CDMA-amanethiwekhi. Ngokufanayo, izixazululo GSM kuphela asetshenziswa amanethiwekhi eselula enjalo.

Isobho asekelwe

Ukusebenza solwazi senethiwekhi CDMA ngamakhasimende kumadivayisi amaningi. Esokuqala iselula kwamazinga. Sinenkosi ezingeni iphansana ukusebenza: ingxoxo, umbhalo kanye multimedia imiyalezo. Kwezinye izimo, lolu hlu lungaboniswa ukudluliswa kwedatha. Ngakho impendulo yombuzo othi: "? I Phone CDMA - kuyini lokho?" - iyona ncazelo elandelayo: "Kuyinto idivayisi evumela ukuba wenze amakholi, ukuthumela futhi wamukele umbhalo noma multimedia imiyalezo noma ukuxhuma kwi-Inthanethi e-CDMA-amanethiwekhi." Eyesibili uhlobo amadivayisi ingasetshenziswa amanethiwekhi ezifana - eye-. Abakwazi kuphela ukwenza umsebenzi owodwa kuphela - ukuqinisekisa ukuwudlulisa reception kwemininingwane kusukela kuwebhu lomhlaba ku-PC. Olunye uhlobo idivayisi - mobile Wi-Fi imizila. Zenza into efanayo modems, kodwa kulokhu khona kukhompyutha akudingekile uxhumano. I-router inikeza engenantambo endaweni inethiwekhi, lapho kungenziwa exhunywe iyiphi idivayisi ne WiFi Lidlulisela. Uhlobo yokugcina amadivayisi - smartphone. Lokhu mobile lwedivayisi okuyinto enwetshiwe ngokusebenzisa isofthiwe ekhethekile. Kulokhu, ubuke amavidiyo, futhi ulalele umculo futhi uxoxe ekuxhumaneni nomphakathi ... ngisho njengoba ingasetshenziswa mobile wifi router.

Opharetha e-Ukraine

Kuze kube muva nje, e-Ukraine kuye kwaba opharetha eziningi mobile, okuyinto esebenza kule ejwayelekile. Lokhu "Welton", kanye "igagasi Ukraine" futhi People.net futhi "Intertelecom". Kodwa manje, qhubeka ukunikezela imisebenzi kuphela ezimbili zokugcina. Eyokuqala, ababili babo babehamba olwathengwa "Intertelekoma" ababhalisile zawo, bazihlanganisa inethiwekhi yayo. Ngakwelinye ihlangothi, People.net ngenxa yezinkinga zomnotho waqala "cisha" kwalolo ngwengwezi, ngenxa yalokhu abaningi amakhasimende akhe baphoqeleka ukuba ushintshele ku esincintisana yayo ngqo - "Intertelecom", okuyinto ke waba kuphela kazwelonke CDMA-opharetha. Ngesisekelo kwesisekelo salo zokubhalisa siqukethe ezimbili-CDMA-GSM amafoni. Odessa - idolobha ngawo opharetha sekuqalile mashi kwayo okunqobayo ezweni lonke. Manje ukumboza ihlanganisa ingxenye enkulu yezwe. Ngakho ukuthi abanikazi CDMA-amadivayisi ungasebenza e-Ukraine, inethiwekhi yeselula eyodwa kuphela.

isifinyezo

Lesi sihloko kuye kwashiwo yombuzo: «I-CDMA amafoni - ke amadivayisi ziyini na? "Futhi, inikezwe izici ukubaluleka onobuhle wangempela lolu hlobo idivayisi, opharetha mobile, ezihlinzeka kule ejwayelekile e-Ukraine. Noma imiphi yale onobuhle kuyoba ngokuthengwa kakhulu futhi zikuvumela ukuxhumana futhi zithole imininingo esuka kwi-Inthanethi.
