If you really want to install a system that is redundant and survivable, then I
repeat: the new portable ATSC receivers would do a good job. Better than
cellular systems. For reasons I already gave.
There is no reason why the ATSC receivers and/or HD Radio receivers(?) cannot
be incorporated into smart phones (and tablets, for that matter), so as to
bypass the cell network in cases like these. Except that, as we already
discussed, the cellcos would much rather their users paid them for any radio or
TV programs, and relied only on their walled garden spectrum.
So, you would rather the FCC actively supported the cellcos' wishes, grabbing
spectrum from the better technical solution, to favor the solution that can
charge more to customers and provide less reliable service during the
emergencies you pretend to be concerned with.
Or maybe the bit about "reliable alert system" was just noise.
