Nortel and Qualcomm have tested technology that could allow mobile phones to seamlessly switch between CDMA and Wi-Fi networks during voice calls. The two companies tested a solution using Nortel's IMS-based Voice Call Continuity network solution and a Qualcomm chipset that uses an IMS/VCC client. The tests showed that calls can be successfully handed off between the two different types of networks in a manner similar to GSM-based UMA systems. This would let CDMA carriers offer customers services such as T-Mobile's Hotspot @Home. Nortel and Qualcomm expect to have the IMS/VCC network and devices ready by mid 2008.

This makes sense...

I heard about a month ago that Sprint was stopping its development of a device that would allow you to use a cell phone off of a broadband internet for low coverage areas. If just make a phone and add a fee, that would help a lot of thier customers.

who's gonna be first?

so who is going to be the first to jump on this, VZW, Sprint or (God forbid) alltel?

Sprint could make a big gain by building this off of Wimax once it rolls out, VZW could add it to the LTE platform, and does Alltel even have anything working right now?

That would be completely awesome - although, sadly, I imagine that even if Verizon starts offering it, they'll charge an arm and a leg for it...
