Re: How many channels can be bonded over Docsis 3.0?

Why not just expand the entire network to 1.5Ghz and beyond? Put more upstream channels up there, along with downstream. The higher frequncy should allow more bandwidth also.

"just expand the entire network to 1.5Ghz and beyond"

There's a lot of time and money in that "just"!

Even if the coax cabling itself was OK with that, extending the HFC network to 1.5Ghz or higher would involve replacing alot of the other passive and active equipment in the system, including all the line amps and taps, much of which were originally designed to go out to "only" 750 MHz or less.

Also theres a reason that upstream is using low frenquancys
highs and lows are effected diffently by distance so having the differance so great allows for better tilt adjustments.
