| The hard part is the back end infrastructure ties...
CDMA 1x/EVDO uses ANSI core
iDEN uses Motorola technology, which uses components of GSM (SIM, GSM signalling)
Xohm uses ?? IEEE spec'd air interface, but who knows what for back end roaming, billing, etc.
CDMA to iDEN _shouldn't_ be that difficult to bridge, someone just has to create a gateway that allows the 2 cores to 'speak' to each other. At onetime there were 'GAIT' devices that were more of a hack job that worked by having 2 phones in one  it allowed for both SIM cards and GSM and also had TDMA/AMPS phones with ESN. Handoffs didn't work, as both infrastructure and devices ran as separate infrastructures.
In the not too distant future, this will have to change, as there will be different devices running on different cores and many should be able to 'speak' to each other.

Helena, AL | Sprint has already "halfway" bridged them, they have the Powersource Hybrid phones which are CDMA voice and iDEN for Direct Connect. Would they deploy it at the network level or tower lever? |

1 edit | I suspect that they could actually just have both running at the same time, as traditional voice and data are on CDMA only, and PTT are on iDEN only.
If this allowed for PTT to handoff between iDEN PTT and QCHAT as well as standard voice and data to handoff between iDEN and CDMA 1x/EVDO, then I'd say they have it partially done.
