CDMA 3G services
Themodemoperatesoveratypeofwirelessnetworkcalled
CDMA (CodeDivisionMultipleAccess).
CDMA 3Gtechnologyprovidesavarietyofconnectivity
features,dependingonyourserviceproviderandaccount:
• 1x‐EVDORev.AsupportsInternetconnectionswithdata

1.8 Mbps(uplinkto
thenetwork).Averagedataratesare
450‐800 Kbps(downlinkfromthenetwork)and
300‐400 Kbps(uplinktothenetwork).Actualspeed
