VoIP over EVDO: Are we there yet??

November 18, 2006 8:15 AM

VoIP over EVDO. If you've tried it (especially on Sprint's Rev A EVDO), how do you like it? I'd be using Skype, using it rarely, and only using it during calls -- not leaving it idling and using bandwidth. (With my current Sprint phone-as-modem setup on 1xRTT, I average 400-600ms pings -- i.e., too much latency for VoIP even if I had enough bandwidth. But on Sprint's now active EVDO Rev A, they claim latency of 100-150ms and upstream averaging 300-400k.) Yes, I know EVDO is not in the TOS. And I connect primarily from NYC in strong-signal areas.

Response by poster: My *current* connection is 400-600ms, as I said, and I agreed with you that that's too much for VoIP. I'm asking about people's experiences using EVDO, especially Rev A.

Thanks for the pointer to Gizmo!

Response by poster: Yeah, I think Rev A is the first cellular data network that will be usable for VoIP. People are reporting consistent real world latency in the 100-200ms. If you google the exact phrase "voip over evdo," you see people doing various speed/quality tests with previous versions of EVDO, which are usually characterized as "almost there" with latency being the issue. This imples Rev A could be the first usable network for VoIP.

I was hoping to get some responses here from early adopters of Rev A, but it's probably a few weeks too early to have asked the question. I'll try again soon. I really appreciate the pointer to Gizmo and I'll be watching it carefully (especially as it gains more area codes for Call In numbers), since it looks preferable to Skype for several reasons. Thanks!
