VOIP Over EV-DO Rev. A Put To Test
Strange
Strange how someone would think of using VOIP on a cell phone.....
But this does provide a number of potential problems:
1) Call quality. Seriously, I've tried Vonage in different locations with vastly different results. On top of that, using it with various phones yields different results - some phones sound like crap; others are fine. And, cramming 30 people on one channel is bound to have quality issues.
2) Dropped calls / Network problems. How well is this going to be handled? Current phones do a good job combating this, but it hasn't always been this good. It wasn't long ago when dropping calls was common.
It will be interesting though.

I think one idea is using VoIP over a broadband card from your SIP client installed on your PC. Long distance calls over VoIP (Gizmo, Skype, etc.) are inexpensive when compared to calling from your cell phone.

I don't think it is particularly strange to use VoIP on a cell phone. That was actually one of the original intents of higher speeds of data. It would increase efficiency and push down operating costs, and of course cut prices for the consumers. It's always been something that companies have been hoping for as fast enough speeds became available.
As far as your two concerns, I agree that call quality will be an issue. When I first read this release my immediate reaction was that a company like Verizon will never utilize this to sacrifice the quality that their name has come to represent.
As for the second concern, I actually think that dropped calls and network issues will be less of a problem through VoIP. Reason being that data trans...

Quality should not be an issue. I've talked to the Qualcomm engineers working on this at CTIA and other trade shows, and everything about it will be as good or better than current 1xRTT voice. In fact, latency may actually be slightly better, believe it or not.
This isn't VoIP like Vonage. VoIP is a very broad term that just means voice over a packet-based data connection.
Current 1xRTT is voice over a data connection, it's just circuit-switched instead of packet-switched. Packet-switched adds bit of overhead, but the improvements in EVDO Rev. A are more than enough to make up for that.
So what we have is a major improvement at a low level, enough to allow adding an extra layer with no degradation in quality. It will be the exact sa...
