    CDMA is not obsolete or dead by any means. Once SVDO (Simultaneous Voice and Data Operation) is in place on carriers outside the US (yes, Sprint and Verizon currently use this standard for CDMA), the technology will rise again, especially on places worldwide where Nextel will have to find a way to bring 3G data, and with iDen it cannot be done (which is why Sprint is making sure Direct Connect is perfected in order to have a new PTT standard, and more likely not be GSM based as iDen was.

    No one will switch back to CDMA outside the US or even inside for that matter. GSM is entirely too convenient for carriers and consumers alike.

    Like a few have mentioned, CDMA has one foot in the grave and the other on a banana peel up here. I'd love to see a business model in the future where you buy your handset at a non descript phone store anywhere in the world and throw your sim in and be done with it.

    CDMA is not dead by any means. China mobile which has 650 million customers uses CDMA and is growing. The largest carrier in India which has 475 million customers also uses CDMA. That plus the US customers on CDMA is 1.2 Billion that's almost 1/2 of the total cell phone market in the world......

    Again, CDMA is dying off. The carriers overseas who still use it are phasing it out, and Verizon and Sprint have plans to shut it down within a decade.

    Once VoLTE handsets are out, CDMA becomes especially silly. The network will be operated as a legacy network for old devices, but towers will be shut off, coverage will decline and eventually the whole thing will go dark as CDMA devices get swapped for LTE ones.

    Even Qualcomm, which invented CDMA, has a migration plan to GSM/LTE for its customers on EVDO.

    It does, but what about when a VoLTE network goes fown? GSM and CDMA networks will be backups, so they're not going anywhere.

    Why do I say this? In order to depend only on a VoLTE network, that network will have to be always on and no interruptions of any kind when it comes to servers and backbone, and that theory of running on VoLTE only would only work in a perfect word. This is why providers will invest on modernizing their 3G and 4G networks as they will become the backup for VoLTE, something Sprint is currently doing (Network Vision equipment has the flexibility to add new technology as it becomes available, and which leaves the usage of VoLTE open and possible in the future, as well as securing their 3G and 4G networks), and soon enough all providers will have to do before they run into serious bandwidth issues

    And how do you also expect Nextel at the international level to use iDen (which is GSM based) provide 3G data service sometime in this lifetime? Let me give you a little secret. They are watching very closely on how Direct Connect and Network Vision deployment at Sprint goes for an idea on how to approach the future (perhaps not fully dependent on CDMA, but having that as an option since for some reason is more flexible for PTT than GSM actually is and proven with the miserable failure of AT&T's idea they had for a PTT competitor but could not figure the 3G/4G data and PTT when it comes to increasing offerings to smartphones without the use of a dedicated app).

    Once again, CDMA may not be the norm worldwide, but is far from dead with all the advancements. Sure, GSM would be far easier to run, but to do PTT with 3G/4G data speeds even on open GSM is not a choice Nextel want to take a risk on.
