Kwaye Kutheni ii-Cell Phones zibizwa ngokuba ngamafonti e-cell?
Ifowuni nayiphi na ifowuni ephathekayo esebenzisa iteknoloji yenethiwekhi yeselula ukwenza kunye nokufumana iifowuni. Igama livela kwisakhiwo esinjengeseli zala manxeba. Kukho ukudideka malunga neefowuni ukuba yinto eyahlukileyo kwii-smartphone, kodwa ngokuqinisekileyo, yonke ifowuni ephathekayo, ukusuka kwi-handset yakamuva ye-Android kwifowuni elula, ifowuni. Konke malunga nobuchwephesha esetyenziselwa ukudlulisela iifowuni yakho, kunokuba i-handset ngokwayo ikwazi okanye ayikwazi ukwenza. Ngethuba nje ifowuni inokudlulisela umqondiso kumnatha womnatha, yilefowuni.
Ixesha I-Cell Phone iyatshintshana kunye nemigangatho yefowuni kunye nefowuni yefowuni . Zonke zithetha into efanayo. Ixesha le- smartphone sele libhekiselele kwisefowuni enika izixhobo eziphambili ngaphezu kweefowuni, imilayezo ye-SMS kunye nesofthiwe yomququzeleli wesiseko. Ngokuqhelekileyo, xa uthetha ngeefowuni zefowuni, ifowuni isetyenziselwa ukuchaza ifowuni elula, ngelixa i-smartphone isetyenziselwa ukuchaza iifowuni ezithintekileyo zefowuni.
Ifowuni yokuqala yokufumaneka ngentengiso iyenziwa ngu-Motorola phakathi kuka-1973 no-1983, kwaye yayithengiswa e-United States ekuqaleni kuka-1984. Le fowuni enkulu ebizwa ngokuthi i- DynaTAC 8000x , ibiza i-3995.00 yee-dollar kwaye yayidinga ukuhlawuliswa emva kusetyenziswe imizuzu engamashumi amathathu kuphela. I-DynaTAC 8000x ayifumanekanga njengefowuni xa kuthelekiswa namacebo esisebenzisa namhlanje. Kuqikelelwa ukuba kukho ii-bhiliyoni zeefowuni zeefowuni ezisetyenziswa ekupheleni konyaka ka-2012.
IiNethwekhi zeeNethwekhi
Inethiwekhi yeselula, eyenza iifowuni igama layo, lenziwe ngama-masts eselula okanye iinqaba ezihanjiswe kweli lizwe kwipateni efana negridi. Isikiti ngasinye siquka indawo encinane yegridi, ngokuqhelekileyo malunga neekhilomitha ezili-square ezibizwa ngokuba yiSeli. Izithuthi ezinkulu zeefowuni (AT & T, Sprint, Verizon, Vodafone, T-Mobile, njl.), Zime kwaye zisebenzise ama-masts zazo zamaselula kwaye ngoko zilawula izinga lokufihla kwamaselula abanokubanika. Amaninzi amaninzi anjalo angafumaneka kwinqaba efanayo.
Xa usenza umnxeba kwifowuni, uphawu luhamba emoyeni ukuya kwisikwere okanye kufuphi nendawo, kwaye emva koko luhanjiswa kwintanethi yokuguqula kwaye ekugqibeleni kuya kwidibanethi yomntu obizayo nge-mast kufuphi nabo. Ukuba wenza ucingo ngelixa uhamba, kwisithuthi esishukumisayo umzekelo, unokukhawuleza uhambe ukusuka kwinqanaba leeselithi enye ukuya kwelinye icala. Awekho iiseli ezimbini ezidibeneyo zisebenzisa i-frequency efanayo, ukwenzela ukuba ugweme ukuphazamiseka, kodwa ukuguquka phakathi kweendawo zamatye ezinqamleziza kuya kubakho ukuthungatha.
Umthombo
Kwamanye amazwe, ukufihla kwamaseli kumalunga nantoni na ukuba unesinye seziphathamandla ezinkulu zesizwe. Kwinqanaba. Njengoko unokulindela, ukukhutshwa kwamaseli kwiindawo ezakhelwe ngokuqhelekileyo kubhetele kunezona ndawo ezisemaphandleni. Iindawo apho kuncinci okanye akukho nkonzo ihlala khona apho kukho ukungena embi, okanye iindawo ezingenakuncedo kwizithuthi zeseli (ummandla onabantu abaninzi, umzekelo). Ukuba ucinga ukutshintsha umphathiswa wakho, ngokuqinisekileyo ufanele uhlolisise ukuba ubone ukuba yeyiphi inqaku elikuloo ndawo.
Izilwanyana zamaselula kwiindawo ezakhiweyo ezifana nezixeko zihlala zisondelene kunye, ngamanye amaxesha zibe ziincinane njengeenyawo ezingamakhulu ambalwa, kuba izakhiwo kunye nezinye izakhiwo zingaphazamisa uphawu. Kwiindawo ezivulekileyo, umgama phakathi kwama-masts unokuba ngamakhilomitha ambalwa njengoko kuncinci ukuphazamisa amaza omsakazo. Ukuba isalathisi seselula sinobuthakathaka (kunokuba singekho), kunokwenzeka ukuba abathengi bathenge i-repeater yeselula okanye i- extender ye-network , ezo zombini ziyakwazi ukukhulisa nokukhuthaza uphawu olubuthathaka.
