Spectral density is a major factor.

It is a shame that SMS and other low MTU packets aren't transmitted over a low bandwidth channel, or at least as a failover option. SMS coverage would be doubled in range, at least.



Like pagers? Probably just a function of effectively duplicating all of the management/authentication/security on top of another physical layer.


No, like LTE Cat NB1 or LTE Cat 0, but at higher transmit power.
