There are already RF/DOCSIS hybrid systems. DOCSIS is a very expensive idea to go with. The head end is the primary cost, but so its the client RF system. The system I looked at was 75K not counting the cable head or modems (this was also about 10 years ago, I have not heard that it was any cheaper today). If you already had a DOCSIS system then it helps. I think Ubnt would be a good contender here. It depends on the rules for channel bonding. If we have say 8 channels (40mhz) then we could use 40mhz airmax. Yummie. And, to my surprise, I have found palces with 15 channels open, and 10 miles up the valley, no upper channels at all open. I have been there, I have put a antenna up 30 feet (and more, a client has a 75ft crank tower for tv) and its pretty impossible to get more then a handful of channels, and most of the ones listed are not receivable. I do not know what options we have for those area, where they are in the coverage zone but have no signal due to mountains and such. Is there any mechanism in place, or being thought of, that would let us have a exemption or exception to the rules for channel sitting? Namely, Say I have 2 open channels, 30, 31. Can I ask 29 or 32 for a waver? "You can use this channel ,at this power, with your antenna(s) pointed as such that it does not cause us interference". this would be very useful in a case where that channel (29/32) is used to TX (namely away from said market) and the clear channel is used to RX. We could then design the networks with lots of dirt between us and them. I knwo I have very tall mountains and many low site butting right up against them. I could blast out on some channels and the over lapping station would never hear me (mtns, distance, and direction) as well the market does not use their channels as they do not come in as it is. (We put in OTA & HD Antennas).
