Re: Why does TV get special treatment? Not sure where you are getting your numbers from.
DTV delivers 19.4 Mbps over a 6 MHz channel or 3.3 bits per hertz.
LTE is around 5 bits per hertz, not all that different.
DTV has a lot of forward error correction to deal with high path attenuation/ fading. If it were not for that a 6 MHz channel could carry 40 Mbps (6.7 bits per hertz) like Cable.
I agree the future of fixed TV will likely be IPTV, but first mile connection will need to be much faster, around 100 Mbps for a family of four.
IPTV is definitely not free. Current broadcast model is very cost effective way to send the same program to many viewers. IP multicast is not yet ready for prime time requiring separate feed for each viewer.
