EV-PAB yog ib qhov kev sib txuas lus siv high-speed network siv rau cov ntaub ntawv siv wireless , feem ntau siv Internet thiab pom tias yog siv lub tshuab xa xov zoo li DSL lossis cable modem Internet .
Qee cov chav kawm ntawm cov xov tooj ntawm tes txhawb EV-PU. Cov xov tooj no tej zaum yuav muaj los ntawm ntau lub xov tooj muaj thoob ntiaj teb xws li Sprint thiab Verizon nyob rau hauv Teb Chaws Asmeskas Ntau PCMCIA adapters thiab sab nraud modem kho khoom nruab ntug los pab kom laptops thiab handheld devices rau EV-DO.
Hov YUAV UA LI CAS?
Txoj cai EV-DO siv kev sib txuas lus asymmetric , faib ntau dua bandwidth rau downloads dua li uploads. Tus txheej txheem EVDO Revision 0 txheem txhawb txog 2.4 Mbps cov ntaub ntawv cia tab sis tsuas yog 0.15 Mbps (li 150 Kbps).
Ib qho kev hloov ntawm EV-Ua hu ua Kho Nqi Kho A, nce download speeds txog 3.1 Mbps thiab uploads rau 0.8 Mbps (800 Kbps). Kev Kho Tshiab Tshiab-Yeej Kho Nqi B thiab Revision C Kev Pab Them Nees Tuam Tshaj Yug Yooj Yim Them Cov Ntaub Ntawv Tawm Suab Ntxiv Los ntawm Aggregating bandwidth los ntawm ntau yam kev sib tshaw wireless. Thawj EV-UA Rev pib B pib dov tawm hauv xyoo 2010 nrog kev txhawb nqa rau downloads txog 14.7 Mbps.
Raws li nrog ntau lwm cov kev cai network , qhov theoretical siab tshaj plaws cov ntaub ntawv ntawm EV-Ua tsis tiav hauv kev xyaum. Real-world networks yuav khiav ntawm 50% los yog tsawg tshaj ntawm cov nqi ceev.
