I continue to wonder why the US cellcos would allow this to happen, UNLESS the 
LTE overlay network were their own. We have the unfortunate situation where 
cellcos control what type of phone they'll allow. It seems unlikely that they 
would allow free access to TV to their phones, over someone else's LTE 
frequencies, any more than they jumped at the opportunity to use ATSC-MH.

The other thing is, wouldn't it be nice, for robustness, to create some sort of 
n-FSK scheme that had adequate b/s/Hz? Seems like not doable, but FM is more 
impervious than PM to distortions. I think the original 2G GSM used FM (it was 
called GMSK), but it was limited to something like 1 bit per symbol. Got to do 
some more searching on this topic.
