Anything's possible but look at the shape of a DTV waveform and compare it to the shape of an OFDM broadband wireless signal. Now look at the space between those two waveforms if they are on adjacent channels. It's kind of like putting two bricks side by side with no space in between. Who is going to interfere with who the most? Looks like the DTV signals will interfere with our AP receivers AND our CPE transmitters will interfere with nearby television receivers. Of course, I could be wrong.... What's your take on it?
