I'd love to read a discussion about whether Wi-Fi, 3G or LTE is the most preferred link of choice for IoT and M2M.
I know its horses for courses, but isn't the general hierarchy of preference:
Wi-Fi: Cheap and fairly widely available or easily deploy-able
3G: Nearly as cheap if available
LTE: Least cheap, least available
It seems as though all of this is really riding on cellular providers to adopt this. All of today's newer phones provide LTE. What manufacturer would want a phone that doesn't provide Wifi and 3g too?..
Like the idea of driving down 4G chip costs. I also wonder, why in the world adding 4G adds ~150$ to device cost. But not sure, about the prospects of a 4G chip without 3G/2G . Most often, your network coverage for 4G is limited. Premium vendors like Apple samsung is unlikely to opt for such a device. If you dont move around much, and lives a area with good 4G coverage. Then it might make sense to get a 20$ 4G chip device vs 150$ 4G/3G/3G chip device.
