    Default EVDO Slow speed due to default configuration

    Dear friend,

    We have soft launched the Evdo service and observed slow speed(0.3Mbps) even for single subscribers.From the subscriber interface trace we observed the referencePilotStrength 4.We have configured 3 E1 for s 1/1/1 Evdo configuration BTS.

    I am new in EVDO system.I have configured all the parameter as default.

    What are the parameter in bss that i should modify for evdo system to increase the speed.Our system vendor is huawei ,BSC 6680 and BTS 3606E.

    Please kindly support in this issue and if you have HUAWEI TROUBLESHOOTING DOCUMENT FOR EVDO SYSTEM ,Pls upload.

    Default Re: EVDO Slow speed due to default configuration

    looks like you're using QOS. If yes, then check related settings and set them according to your (operators) needs. If not, turn it off.

    connect a local ftp server to pdsn and then test throughput.
