Well it still needs a few constraints
At a range of 3 feet I bet we can do better than 12 bits/hz and use 100ghz.

I guess i needed to define better
but the gist is of the usable spectrum probably less than 500gbps
"Some will say?"
Tell that to all of the highly successful ISPs (most of whom are
not stereotypical WISPs, but are 95% fiber and 5% microwave) using
60 GHz for 500 to 700 meter distances, places where it could cost
$130,000 for a fiber build.
And one strand of fiber? Probably not far from the same by the end of
the decade. 100Gbps already exists.

I'm guessing you head to infinity on that one. The shortest wavelength
is 1.616 x 10^-35 meters or a frequency of 1.8552 x 10^43 Hz.
Unfortunately the amount of energy required to create that frequency
also results in the creation of a black hole and your transmitter
disappears.

Oh, yeah, photon energy. I forgot about that. So there is an upper limit.
