Really? Hundreds of millions of mobile devices can receive signals in the 600 
MHz spectrum?

Sorry, Craig, but rubbish. It can work either way. Wide channels save a bit 
from avoiding as many guardbands, and that's the extent of it.

Again, not true. With use of LTE, it won't be spectral efficiency AT ALL that 
is gained. It will be ease of reception, if they use a dense mesh of towers in 
SFNs. Been over this too many times to count. Use less than dense SFNs, with 
LTE, and you're reducing b/s/Hz well below that of 8T-VSB. Use a single stick, 
well, ease of reception, with a tiny antenna, goes out the window.

If there's a threat to OTA broadcasting, it is that people are migrating either 
to Internet access or to access on demand from mobile devices. The use of 
one-way broadcasting will be increasingly limited to those programs that people 
really want live, rather than on demand. So, for broadcasters to create their 
own content seems like a really good idea, and also to gain an online presence. 
And the good news is, I think, that the 39 percent national cap does not apply 
to a station group making its content available online!
