Iifowuni zeCDMA - yintoni na? Ifowuni kunye neefowuni eziqhelekileyo ze-CDMA

Ukuba sichaza ngokupheleleyo ukuchithwa okupheleleyo kwezi ncwadi ezine (CDMA), ngoko siya kufumana amagama alandelayo-Idilesi yeCandelo loFikelelo lokuFikelela. Kwaye nangona sichaza le xabiso, siyiguqulela ngolwimi esiyayiqondayo, asikwazi ukuqonda okuninzi kule nto. Siyaqaphela ukuba xa siyiguqulela eli binzana kwisiNgesi, siya kufumana ukuba le nkqubo yenkqubo enkulu yokufikelela kweefowuni. Yiyo ke iifowuni zeCDMA zizonke. Ziye zaziwa kakhulu namhlanje. Kwaye akumangalisi. Ngolwazi olungakumbi, yintoni le, ii-CDMA zefowuni, siza kuxubusha ngokuqhubekayo kwinqaku lethu.

Iyiphi ifowuni ye-CDMA?

Ukuze kuqondwe yonke into ebalulekileyo yile teknoloji, engacacile ngokupheleleyo, sinokuyifumana ukufanisa okuthile. Kungenxa yakhe ukuba siyiqonda ngokubanzi into enikwe into. Yonke iya kuba yinto elula ngakumbi kwaye iyaqondakala, ukuba udweba umzekelo nale fowuni efanelekileyo. Njengoko sonke siyazi, kukho ukudibanisa kweendlela ezininzi, eziqhelekileyo zazo zi-GSM kunye ne-NMT.

Ukunxibelelana kweNMT

Ngoko, masihlalutye oko kukuthi, ii-CDMA-fowuni. Kwamazwe amaninzi kukuncedisa uxhulumaniso lwe-NMT yefowuni yomnxeba ukuba abaninzi abaqhubi baqalisa umsebenzi wabo. Emva koko basebenzisa oko kuthiwa ukwahlula ngasese kwezinye iziteshi. Ngokusekelwe kulo, sinokuqonda ukuba umthengi ngamnye ngokuthe ngqo wanikezelwa ngolu hlobo oluncinci lwamaxesha. Kwakungenxa yeli xesha ukuba angakwazi ukuqhuba unxibelelwano. Yatshanje ingenakulungiswa. Kwaye sizathu sini. Khawucinge ukuba kwinqanaba leemitha ezili-3 kukho abantu aba-3, kwaye ngamnye wabo uthetha ngefowuni. Akukho ntuthuzelo. Kwaye ngoku baye bathuthela kumgama owaneleyo ukuba bangavalelane.

Oku kuchaza ukwahlula kwezithuba zamashaneli. Yilokho iifowuni ze-CDMA zisebenzisa. Ngalo mzekelo, ngokubanzi ezinye iinkcukacha ziyacaca.

Umgangatho wedijithali ngendlela ye-GSM

Lo mgangatho woqhagamshelwano lwezedijithali esisetyenziswayo kwimihla ngemihla. Kwamazwe ahlukeneyo, kusekho umsebenzi othe ngqo. Le nkqubo ibuye isebenzise ibanga leendlela ezahlukeneyo ngendlela eyahlukileyo. Unxibelelwano lwale hlobo aluhluli uluhlu oluthile kwiindawo ezithile zomsebenzisi ngamnye. Kodwa le nkqubo yenza oku kwinqanaba elithile ngexesha. Oku kuhlulwa okwethutyana kweziteshi esizidingayo. Okokuthi, isibini esithile sabantu sithetha ngexesha elithile, okufunekayo kubo, kwaye esinye isibini sithetha ngexesha elifanelekileyo, kwaye ngelo xesha, ngaphandle kokudala abanye abantu. Ngokumalunga nelolu hlobo, iifowuni ze-CDMA nazo ziqhuba umsebenzi wazo othe ngqo. Kodwa siza kuxubusha oku ngcaciso ngokubanzi kwicandelo elilandelayo.

Imigaqo yokunxibelelana yeCDMA

Ngoko, sifikelele ngokufanelekileyo kwimilinganiselo esiyimfuneko. Ngaloo ndlela, isebenzisa uluhlu olufanayo njengoluhlobo oludlulileyo lwenxibelelwano, kodwa luhluke ngendlela eyahlukileyo. Umzekelo, ngenxa yokuhlula kweefowuni ezithile. Iyiphi ukwahlula kwekhowudi kule meko kunzima ukucinga, ngoko masibuyele kwisifaniso. Ukuba abantu bathetha kwaye baphazamise umhlobo-kubi, kodwa ukuba bonke abantu bathetha ulwimi lwabo, oko kukuthi, abanye-ngesiRashiya, abanye-ngesiNgesi, njalonjalo. Yilo kanye ulwalamano kunye nekhowudi yoqhagamshelwano. Ngoku ngoku sonke siqaphela oko kukuthi, ii-CDMA zefoni. Kodwa ke, le ngcaciso ayifumanekanga kwiinkcukacha ezininzi njengoko singathanda.

Imbali yoxhumo oluhle kunomhla

Iinkonzo zabasebenzi abahlukahlukeneyo kakhulu, emva koko konke, kunye ne-CDMA kwakhona i-Intertelecom, yaqala ukubonelelwa ngo-2000. Wonke umntu uyaqonda ukuba ngoko iindleko zeefowuni zazinkulu, kwaye ukufumana isigxina kwakungelula. Kodwa nangona kunjalo unxibelelwano olunikeziweyo lwaluyimfuneko, nangona lincinci. Umqhubi ngamnye ngelo xesha wayenetyala leenkonzo zakhe, ezenza umdla wabathengi. Lo mqhubi uphuhlise kancane, kwaye kuyo yonke le minyaka iindleko zalo zokuxhunywa ziye zahla kakhulu, kwaye umgangatho weenkonzo awuzange ukhule. Oku kukhenkethi abathengi abaninzi rhoqo ngonyaka. Okwangoku, sinexabiso elincinci, kunye neenzuzo ezininzi.

Kwakhona kufanelekile ukuba uqaphele ukuhlanganiswa kwalolu hlobo lonxibelelwano, kuba unokuzikhethela isantya esifanelekileyo kuwe.

Iinzuzo zokunxibelelana kweli hlobo

Iifowuni ze-CDMA zisetyenzisiwe kakhulu kwaye zithandwa kakhulu. Kule nto sinokuqonda ukuba kukho inzuzo eninzi kule fomu. Ifowuni ye-CDMA ifakile iquka uluhlu olubanzi lweenkonzo ngoncedo lwale nxu lumano, siya kuqwalasela ngokubanzi.

1. Okokuqala, kubalulekile ukuqaphela umgangatho woqhagamshelwano. Kule meko ukuba lo mgangatho ubonisa iiparitha eziphezulu kuzo zonke iintlobo zonxibelelwano. Ngoxwebhu olunjalo, uya kuva umntu onomgangatho ofanayo, njengokungathi umi phambi kwakho. Kwaye oku kuya kubangela ukuba nakumanani angabonakali ungakwazi ukwahlula kuphela ngexabiso lomntu womntu ngaphaya komnxeba wefowuni.
2. Olu xhumo lukhuselwe ngokupheleleyo kumanqanaba ahlukeneyo okucoca, awanakho ukukholisa umthengi. Iifowuni ze-CDMA zinaloo propati zixhobo, ezingenakulula ukuziphulaphula. Ukuze uqinisekise ukuphulaphula ifowuni ethile, kufuneka ube nezixhobo ezinokubaluleka ngamashumi amawaka eedola zama-US.
3. Isikhululo salo mqhubi sinokunika unxibelelwano kwinani elikhudlwana lababhalisi kunabanye abaqhubi abafana nalo.
4. Ngokuphathelele imida ekhutshwe ngamafowuni e-CDMA, le nxalenye yale ndlela yoqhagamshelwano ibonisa inani elincinci lwedatha. Kwaye akunako ukuvuya.

Ingcaciso malunga nalezi zifowuni ze-CDMA zichazwe ngokupheleleyo. Ngoku unolwazi olupheleleyo malunga nale divayisi kunye nezixhobo zalo. Ngoko, ifowuni ye-CDMA ikuvumela ukuba ukhethe umsebenzisi ofanelekileyo, kunye neentlawulo ezithandwayo kwiifowuni kunye nokufikelela kwi-Intanethi. ожно смело и, не задумываясь, переходить к операторам данного вида связи. Ngoko ke , kunokwenzeka ukuqhubela phambili kubasebenzisi belo hlobo lonxibelelwano ngaphandle kokungabaza.
