I-EV-DO iyi- protocol yenethiwekhi ephezulu kakhulu esetshenziselwa ukuxhumana kwedatha okungenantambo , ukufinyelela ngokuyinhloko kwe-intanethi futhi kubhekwa ubuchwepheshe be- broadband njengosizo lwe- DSL noma i-intanethi ye-intanethi ye-intanethi .
Amakilasi athile amafoni weselula asekela i-EV-DO. Lawa mafoni angahle atholakale kusuka kubathwali befoni abahlukahlukene emhlabeni jikelele kubandakanya i-Sprint ne-Verizon e-US Amaphakethe ahlukahlukene we- PCMCIA ne-modem yangaphandle yehadiwe ikhona ukuze unike amandla i-laptops namadivayisi aphethwe nge-EV-DO.
Ukushesha Kanjani EV-DO?
I-protocol ye-EV-DO isebenzisa ukuxhumana okulinganiselwe , ukwabela okungaphezulu komkhawulokudonsa okulandwayo kunokulayisha. Isilinganiso sokuqala se-EVDO Revision 0 sisekela kumazinga angama-2.4 Mbps kwedatha kodwa kuphela 0.15 Mbps (cishe 150 Kbps) phezulu.
Inguqulo ephuthumayo ye-EV-DO ibizwe ngokuthi i- Revision A, isivinini esikhulu sokulanda kufika ku-3.1 Mbps futhi silayishwa ku-0.8 Mbps (800 Kbps). Ukuvuselelwa kwe-EV-DO entsha ne- Revision C nokusekela ubuchwepheshe be- C ngokuphindaphindiwe kwamazinga we-data ngokuhlanganisa umkhawulokudonsa kusuka kumashaneli amaningi angenantambo. I-EV-DO yokuqala ye-B yaqala ukuphuma ngo-2010 ngenkxaso yokulandwa kuze kube ngu-14.7 Mbps.
Njengamanye ama- protocol amaningi enethiwekhi , amazinga aphezulu wemininingwane ye-EV-DO ayitholakali ngokwenza. Amanethiwekhi omhlaba wangempela angase agijime ngamaphesenti angama-50 noma angaphansi kwesilinganiso esilinganisiwe.
Futhi eyaziwa ngokuthi: i- EVDO, i-Evolution Data Elungisiwe, i-Evolution Data kuphela
