Can wimax/Evo do simultaneous voice/data?

[kruglovus]

Correct me if I'm wrong. I believe the phone call does NOT drop when switching from the *native* network to roaming, for example from Sprint 3G/CDMA to Verizon 1x. If that is true, then if 4G drops, the phone can fall back to 3G or 1x and keep the phone call.

As stated the Evo's ONLY* voice calling capability is over the CDMA2000 network. While in a call you will not be able to access the 1xEVDO data network.

The outstanding question is if Sprint and HTC will account for the use of the WiMAX radio while in a CDMA2000 voice session. There are a lot of issues that have to be understood, accounted for, tested, and re-tested. While it might seem easy those who understand even a little bit about how the systems play together know it is not.

*Of course someone could write a VIOP app for the Evo but that is a totally different topic and one for which we would need a totally new thread and lots and lots of time!

Actually current phones can make both a a call and access the data on a CDMA2000 network, refer to my original post on this issue. The problem lies in the provider not enabling the feature on there towers and for good reason. There is no reason to go back and spend more money on there 3G network when there rolling out a 4G network which will replace the current 3G network.
