Voice and data at the same time?!? Could it be?

A device using Verizon's CDMA (Code Division Multiple Access) network can handle only data or a voice call in a single session.
Last week, Verizon said its 4G LTE network will go live by the end of the year in 38 wireless cities and 68 airports, and that users can expect download speeds of up to 12Mbps.
The ability to simultaneous carry both voice and data will become commercially available in the first half of 2011, according to the CDMA Development Group, an organization of companies that oversees the development of the technology, the WSJ reported.

Granted it says voice and data over CDMA at the top of the page, later quotes lead me to believe they mean upgrading their current CDMA network to include voice/data, ie; LTE.

The article is rather ambiguous.

I've read several articles that specifically say the current CDMA equipment can be made to access both data and voice. Most seem to point back to one press release, so I won't waste space with multiple links:

From: CDG : News & Events : CDG Press Releases
"A complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call. For example, users will be able to send emails or access the Web while on voice calls; phones with GPS can update maps or download real-time traffic information while on voice calls, etc. This device enhancement, which enables these concurrent voice and data services, is independent of the air link standard and infrastructure."

The greater question is whether this is something that is changed at the tower, the devices or both and if it then requires changes on the devices, are those changes in hardware and/or firmware. From a quick search for more information, the implication is that it would require a hardware change. So, I wouldn't get your hopes up too high.

Further, the question becomes what the associated cost taken in conjunction with the roll out of LTE. Perhaps it's pointless to to push out SVDO and instead just go with LTE. On the otherhand, perhaps SVDO is cheap enough to help stretch the legs of the existing CDMA network in places where an LTE investment doesn't yet make sense as it seems the complimentary enhancement could allow for more spectrum to be used for data.

Who knows...
