Nor I, nor anyone else that ever designed an ATSC receiver, nor the FCC that
'designed' a DTT network that at best, supports rooftop antenna reception for
most of the people most of the time, and indoor reception only for a much lower
percentage of the people much less of the time.
Note that the MMBS system as proposed by CEA in 1999 was going to use OFDM.
Notice a trend in all this? Wireless broadband = OFDM transmission.
Someone earlier made the comment that ATSC is best suited for STL links. To
that I would add that someday -- after mandatory widespread proliferation in
new TV sets -- it could also become an excellent candidate for single-wire A/V
device interconnect, much as NTSC tuners using channel 3 or 4 are today. But it
still is and always will be an extremely poor choice for wireless broadband
distribution of DTV.
