Use Data and talk at same time(SVDO) coming soon!

I thought this would be a welcome advancement in CDMA technology, using data and 1x simultaniously. This would mean no interrupted data while talking or texting, being able to continuously stream while picking up a call?

3GPP2 Approves CDMA 1x Advanced Standard

Full Arcticle here: http://cdg.org/news/press/2009/Aug17_09.asp

Today the 3rd Generation Partnership Project 2 approved a set of standards for CDMA 1x Advanced. The software/channel card upgrade uses interference cancellation and radio link enhancements to increase voice capacity on CDMA 1x networks. According to the CDMA Development Group, the technology improvements (base transceiver station interference cancellation, improved power control, early frame termination, and smart blanking) can be rolled out all at once or deployed in phases across a network. In theory, 1x Advanced can quadruple the voice capacity of a wireless network using the same 1.25MHz of spectrum. The technology will be available in the second half of 2010. Additionally, an upgrade for devices, called 1X Voice and EVDO Data (SVDO), will allow phones to access EVDO data while on a 1x-based voice call. This will let end users send emails or surf the web while on a phone call.

But will US providers be willing to spend money to gain this capability?

If the claims listed in the press release are true I can see it happening. The rollouts for LTE and WiMax are all focused on data and not voice. This will allow them to squeeze 50% more capacity out of their existing voice network.

The question for us is will we get this dual capability on our exisiting handsets.

Finally, CDMA providers catch up with 3G technology that has been available for 3 years now. Sometimes, I love ATT.

Isn't the reason GSM can do Call+Data at the same time due to voice being GSM and data being a variant of CDMA? That would make the CDMA achivement a little better than its GSM variant.
