EV-DO iyi yakakwirira- purogiramu protocol inoshandiswa kune wireless data communications, kunyanya kufambira kweIndaneti uye inonzi inonzi broadband teknolojia yakafanana neDSL kana tambo yepaIndaneti yemasevisi .
Mamwe mapoka emaserura efoni anobatsira EV-DO. Aya mafoni anogona kuwanikwa kubva kumarudzi akasiyana-siyana anotakura foni munyika yose kusanganisira Sprint uye Verizon muU.America Various adapamba PCMCIA uye kunze kwemodemu hardware iripo kuti ive yakwanisa ma-laptops nemichina yekuchengetedza yeEV-DO.
Kurumidza Kupi EV-DO?
IEV-DO protocol inoshandisa kukurukurirana , kugovera mamwe bandwidth ekutsvaga kudarika kuiswa. Yepakutanga EVDO Revision 0 standard inotsigira kusvika ma 2.4 Mbps dhidha yepamusoro pasi asi 0.15 Mbps chete (anenge 150 Kbps) kumusoro.
Shanduro yakavandudzwa yeEV-DO inonzi Revision A, yakawedzera kukurumidza kukurumidza kusvika ku 3.1 Mbps uye kuiswa kune 0.8 Mbps (800 Kbps). Watsva EV-DO Kuvandudza B uye Kuvandudza C tekorogiramu yezvigadzirwa zvekombiyuta zvakanyanya zvakanyanya kudarika dhigirii kuburikidza nekubatanidza bandwidth kubva mumigwagwa yakawanda isina wireless. Iko yekutanga EV-DO rev B yakatanga kubuda muna 2010 nekutsigirwa kwekutora kusvika ku 14.7 Mbps.
Sezvo nemamwe maitiro akawanda emitambo , inoretical data yakanyanya yehuwandu hweEV-DO haisi kubudirira mukuita. Zvechokwadi-nhepfenyuro dzenyika dzinogona kuenderera ne50% kana pasi peyo yakaridziwa yakakurumidza.
