Yup, its called broadband (as contrasted to baseband).  Your local
cable TV people use it for video, but you can use it to mix video and
data.  You get umpty-ump (a technical term) 6 MHz wide channels which
you can use for most anything you want.  A number of vendors make
modems which you can connect to it to give you multiple independent
parallel networks.  It has a second advantage that it can work over a
much larger area than ethernet.  Over a city, if you like.  Its major
disadvantages are that it requires some engineering and that it
requires a centralized "head end" and amplifiers to repeat signals.
