Ngawo onke amarhe okugqibela enza ujikelezo kwi-intanethi kwezi ntsuku ngokubhekisele kwiUkuza okwesibini IPhone entsha I-Apple kuthiwa iyakukhupha ehlotyeni (njengaleyo Abathengi beVerizon kunye neSprint banokufumana isithixo kungekudala ,) kunokuba lula ukuwela kwi-hype. Nokuba le ntetho mayithathwe njengevangeli ilungiselelwe ingxoxo; Ngelixa sinemithombo embalwa eyaziwayo, abantu abakwiCupertino baziwa ngokungagungqi kwimilomo malunga nokukhutshwa kwabo okukhulu kuzo zonke iindawo. Kodwa kutheni ingxwabangxwaba ngosasazo bakanomathotholo, abadlala indima enkulu kwingxelo yeWSJ? Kuyavela ukuba imigangatho ekuthethwa ngayo ngobude ngabatshintshi bemidlalo ukuba (kwaye iseyinto enkulu ukuba) iApple yenza uhambo oluya kwiCDMA. Ke kufuneka sibuze:
Yintoni na ukujongana nayo I-GSM kwaye CDMA kwaye kutheni zibalulekile?
I-GSM, okanye iNkqubo yeHlabathi yoNxibelelwano ngeSelfowuni, yitekhnoloji yonxibelelwano yeselfowuni esetyenziswa yi-iPhone ngoku nge-AT & T. Ukuqala eYurophu njengeGroupe Spécial Mobile, ngoku yeyona nto idumileyo yokuhambahamba emhlabeni, malunga I-80% yabasebenzisi beeselfowuni abangaphezulu kwe-4 yezigidigidi . Kwelinye icala, umntu okhuphisana naye kwi-CDMA, okanye kwiKhowudi yokuFikelela kuFikelelo oluninzi, yitekhnoloji eyenziweyo yeQualcomm evela e-US esebenza ngaphezulu kwe-10% yeefowuni zehlabathi. Abona baphathi baphambili e-US bahlukaniswe phakathi kwale migangatho mibini, kunye ne-AT & T kunye ne-T-Mobile isebenzisa i-GSM kunye neVerizon kunye ne-Sprint Nextel isebenzisa ii-CDMA kwiifowuni zazo kwaye, kutsha nje, izinto ezingenazingcingo.
Oko kuguqulela oku kumava ahlukileyo kubathengi njengoko yomibini imigangatho isazisa ngento enokuthi iselfowuni inike umniniyo. Kwesinye, iiseli ezisebenzisa i-GSM, ngenxa yokusetyenziswa kwetekhnoloji okusasazekileyo, zinokungakhathazeki kangako malunga nokuhambela phesheya ezichaphazela ukugubungela kwabo njengoko ifowuni yabo inokufumana umphathi oyisebenzisayo. Iifowuni ze-CDMA azinakukwenza ibango elinjalo okwangoku, nangona iVerizon ingenelele ekwandiseni inkonzo yayo nge Ukusebenzisana neVodaphone e-UK ukuqhubeka nokuphucula umgangatho kwizixhobo zabo.
Ngokweendlela zokudlulisa idatha, i-CDMA ngokwesiko ibinezantya ezikhawulezayo kunye nenkonzo ethembekileyo. Nangona kunjalo, ngophuhliso lwakutshanje njenge-UMTS kunye ne-HSDPA, i-GSM ivale ubukhulu becala umsantsa kwezinye iindawo, kwaye zombini zibonelela ngesantya sonxibelelwano esithelekiswa nebhendi ebanzi. Okwangoku, abasebenzisi banokuthatha iminxeba ngaxeshanye kunye nokufikelela kwinethiwekhi yedatha besebenzisa i-GSM.
Okokugqibela, iifowuni ze-GSM zisebenzisa iSIM- okanye imodyuli yesazisi-yamakhadi kwizixhobo zazo. Ulwazi olukwiSIM khadi lunokudluliselwa phakathi kweefowuni ezingatshixwanga phantsi kwale meko. Iifowuni ze-CDMA azinalo olu phawu, kwaye ubukhulu becala kufuneka zicwangciswe ngumphathi ngaphambi kokuba zifike kumthengi.
Kwimikhankaso yentengiso yakutshanje- kwaye ngakumbi abo bane-AT & T kunye neVerizon baya entloko-le micimbi ubuncinci ichaphazelekile ngegama:
Ngoku, ngaba i-iPhone yeyona smartphone idumileyo kwintengiso namhlanje? Ewe, nangona i-Android ivala ngaphakathi . Okwangoku, ngaba iVerizon ithathwa njengenethiwekhi ethembekileyo. Ewe, ngokwenza . Nangona kunjalo, ngenxa yempumelelo elawulayo ye-iPhone ukusukela oko yaqala ngo-2007, ukuyinikezela ngaphezulu kwesithwali esinye kunokutshintsha ubutyebi beenkampani ezichaphazelekayo. Iya kuyichaphazela njani i-AT & T, ngubani onokubulela iApple ngempumelelo yayo kunye nasezintanjeni? Iya kufumaneka njani iVerizon iPhone kwimakethi yaphesheya? Ngokutsho kwe-CNN, kunokuba njalo ngasekupheleni kuka-2011 iApple iya kuhamba iye kwiBig Red. Abanye bethu kuya kufuneka balinde ukuze babone.
