Ukuxhumana komuntu bekubalulekile kusukela ezikhathini zasendulo, ikakhulukazi uma sikhuluma ngebanga elide, ukuze kuthuthukiswe ukuxhumana phakathi kwabantu, imindeni noma imiphakathi. Ngokuthuthuka nentuthuko yamadolobha namazwe, lesi sidingo saba nzima kakhulu, yingakho ngo-1854 ubuchwepheshe babukhona ngocingo lokuqala, okwasungulwa ngu-Antonio Meucci.
Kepha kuze kwaba ngo-1973 lapho esikwaziyo namuhla njengo amaselula, unjiniyela wayo wayengu- UMartin Cooper okunikeze impilo i- "Motorola DynaTAC 8000X", iselula enkulu futhi esindayo, ayikho into yobuhle uma iqhathaniswa nalezi ezikhona njengoba kungabonakala esithombeni esilandelayo.

Ngakho-ke isuka ekudingeni yaya kokunethezeka, USD $ 3,995 Kwakuyizindleko zeselula yokuqala, empeleni yayitholakala kuphela kosomabhizinisi nabaphathi balezo zikhathi abasungula amabhizinisi. Ukusuka lapho, umakhalekhukhwini wavela ngokobuchwepheshe, wasuka ku-analog waya kwidijithali futhi-ke wehlise kakhulu usayizi wawo futhi wengeza ukusebenza okuningi kunokubiza nje.
Ngaleyo ndlela, singahlukanisa i- ukuvela komakhalekhukhwini ezizukulwaneni ngezizukulwane:
Isizukulwane sokuqala (1G):
Iqondwa kusukela ekuqaleni kwama-70s kuze kube sekupheleni kwama-80s, ngokufika kweDynaTAC 8000X eyaziwayo. Lesi sizukulwane saziwa ngokukhawulelwa ezwini kuphela nangokusebenzisa uhlelo lwe-AMPS (i-Advanced Mobile Phone System) e-USA naseTACS (Total Access Communication System) ezweni laseSpain. Ama-mobiles abenezindleko eziphezulu nabasebenzisi abambalwa.
Isizukulwane sesibili (2G):
Kusukela ngawo-90, izingcingo eziphathwayo zaqala ukutholakala kalula. Ubuchwepheshe beDijithali bunikezwe ngohlelo lwe-GSM (Global System by Mobile Communications) kanye nemiyalezo ebhaliwe ye-SMS (Short Message Service). Ezinye izibonelo zaleso sikhathi yilezi: MicroTAC 9800X, Motorola StarTAC kanye neNokia 1011 kusukela ngasekupheleni kweminyaka yama-90.
Lesi sizukulwane sinoshintsho olwaziwa nge-2.5G, lapho lunikeza khona izici ezinamakhono amaningi njenge: GPRS (General Packet Radio System) kanye ne-EDGE (Amanani Wedatha Okuthuthukisiwe weGlobal Evolution), nedatha ishesha ize ifike ku-384 Kbps.
Isizukulwane sesithathu (3G):
Ukuthandwa komakhalekhukhwini kufike, kwaqala ukusetshenziswa kwamakhadi we-SIM (chip), kwavela i-internet ephathekayo kanye nezinhlobonhlobo zamamodeli nezinkampani, kubandakanya neyaziwayo: iNokia 1100. Ngaphezu kweNokia 5110/6160 kanye ama-8210/8260 kusukela ngeminyaka ka-1999-2000.
Ubuchwepheshe obusetshenzisiwe yi-GSM, kuvela izinhlelo zokusebenza zemultimedia, ukukhiqizwa komsindo (mp3), ividiyo, izithombe phakathi kwezinye izinhlobo zokuqukethwe. Ungasho kanjani amakholi wekhamera nevidiyo.
Isizukulwane sesine (4G):
Isizukulwane samanje sobuchwepheshe, esibonakala nge-bandwidth enkulu, ngaphezu kokusetshenziswa okukhulu kwama-smartphones noma ama-Smartphones anezikrini zokuthinta nokusebenza okuningi.

| Ukuziphendukela kwamaselula ezithombeni |
Njengamanje, umakhalekhukhwini, ngaphezu kwesidingo noma ukunethezeka, usuvele ubhekwa njengomsizi noma isesekeli esisemqoka, somsebenzi, ezokungcebeleka nanoma yimuphi umsebenzi esiwenzayo. Iyakwazi nokusetshenziswa njengethuluzi ukuhlola impilo yethu, ngokusebenzisa izinhlelo zokusebenza zezokwelapha ezithuthukile ezinembile ukuzisebenzisela noma ngubani.
Singazibuza nje ukuthi: isizukulwane esilandelayo somakhalekhukhwini sizosilethela ini?
Ngisekhona "esizukulwaneni" seMotorola V3, hehehe: ngijabule kakhulu ngeSony Ericsson W508 yami. Angiwathandi amafoni anekhibhodi ye-QWERTY (okunzima kakhulu ukungibhalela, futhi ebanzi futhi embi) futhi angisibonanga isidingo sokuba ne-smartphone ene-iOS noma i-Android. Kuyabiza, ibhethri alihlali, zebiwe.
Hola UFitoschido,
Qaphela ukuthi ngihamba kokufanayo, ngine-Motorola V3i ne-LG MG205, ezindala esezikhona kodwa eziqinile ijojo. Futhi, uma zebiwe noma zilahlekile, akunasisindo huh 😀
Sawubona mngani, ngiyabonga ngokuma ukuphawula. Ngelinye ilanga sizojabula ngo- $ martphone $.
Yebo, ngine-Samsung GT S3370 futhi ngikholwe ukuthi ngiyayikhumbula i-Alcatel HC 800 yami. Kubi, kukhulu, kukhulu ... kodwa ngemenyu yokuhlunga izingcingo engenayo engenakuqhathaniswa nanoma iyiphi enye iselula (ngaleso sikhathi iselula). Ngaleso sikhathi yayiyinhle ukuthi ngibe nokuthula okuncane ngezikhathi ezithile futhi nginqamule emhlabeni womsebenzi ngikhungathekiswe kakhulu, kwesinye isikhathi, ngenxa yokulula kokuhlunga ngokwesigaba Waphila impilo ende kepha ukunyamalala kwakhe sekuvele kuthintekile ngokungamtholi amabhethri kuye noma kuphi.
Ngikhetha nokulula nokwenza okusebenzayo kuselula, ngakho angicabangi ukuthi ngizothatheka nge-IPhone noma okunye, angikudingi.
Ngendlela, i-athikili enhle. Umlando omncane (noma umlando wangaphambilini) wocingo lweselula.
Sanibonani nempelasonto enhle mngani.
Jose
Kuyigugu langempela leselula oke waba nalo Jose, ukuhlunga kwakuyinto enhle kakhulu ngaleso sikhathi. Kumele sigqamise ukumelana nokungqongqoza kanzima nokuwa okwakukhona ama-mobiles angalezo zikhathi, ukube kwakusekhona ukusekelwa nezinsiza, ngokuqinisekile bezizosebenza ngaphandle kwezinkinga kuze kube namuhla ... lokho okulindelekile.
Ngiyabonga ngokuphawula mngani wami nokuthi kube kuhle kanjani ukuba lapha futhi 😀
Impelasonto enhle futhi!
Sawubona Marcelo, kunjani konke, ngiyethemba kulungile. Lapha ngikunikeza isixhumanisi esivela eCiudad PC (mayelana nokuthunyelwe) okungaba nentshisekelo, kubizwa ngokuthi i-athikili: Umsunguli weselula nansi isixhumanisi sayo http://www.ciudadpc.com/2011/04/el-inventor-del-telefono-celular.html
Un saludo
Ngikhohliwe, ngikuxhumanisa lapha: http://www.informamemas.com/2012/08/evolucion-de-los-telefonos-celulares.html
Un saludo
Hola Pedro, konke kuhamba kahle, ngiyabonga 😀
Yebo, i-athikili yakho ingumphelelisi ofanele kulokhu okuthunyelwe, siyabonga ngokuhlanganyela nathi. Kuhle impela.
Mayelana nomngane wami!
Ngiyabonga kakhulu futhi ngokuxhaswa Pedro, impumelelo yamabhulogi akho futhi ngiyabonga ngokwazi imibhalo yami 😀
