It's deja-vu all over again: we will have the same problem we did with CarWings/EV Connect vis-a-vis 3G we did with 2G. A couple of things come to mind:
1) Does anyone know if the chip set on the (replacement/upgrade) TCU modems supports LTE (4G) as well as 3G?
2) Has anyone spoken to Nissan about the prospects of another modem upgrade cycle?
I didn't anticipate that a 3G network shut-down would so closely follow the 2G network shut-down, but spectrum is scarce and 5G is on the way. At least we've been through this once before (although it wasn't pretty), but I know I don't want to lose telematics capability in my Leaf. A key to the magnitude of the problem will be knowing whether the current 3G chip set also supports LTE, which allows for the possibility of a firmware as opposed to a hardware update.
