No, I'm thinking about 180 mhz, kinda close to TV channel 8, but...
out here, the nearest TV channel 8 transmitter is 300 miles away.
Besides, TV antennas are being scrapped all the time; everyone is
switching to Dish TV. Out in rural areas, RFI/EMI from ham gear no
longer bothers anyone watching TV.

Besides, seems like there mite be pulse emitters/detectors that work
at this speed. No Carrier wave, no IF. Technically, its *NOT*
"radio". Ordinary tuners would ignore it; it aint AM nor FM. A 12 db
antenna would be about 13' foot long. Awta go 30 miles to an ISP in
some town that stays up serving users on the weekends. I've tried all
three of the local small town ISPs, which have a nasty habit of
crashing on friday nite, and not coming back online til monday
morning.

Of course it's radio. You'll find that if you aren't radiating a signal,
there's no signal and it's not radio. Otherwise, it's radio. And that
means licensing and all the rest.

And there's a good reason wifi is higher in frequency. Because the
bandwidth is there, to allow for multiple signals. Likewise, the shorter
range means losts of points can reuse the same frequency, because the range
is quite limited. And of course, the higher the bandwidth of data, the
more radio space it uses.

Move to a lower frequency, and you'll have less chance to control the signal.
You may find there's too much interference to other users. There may not
be enough radio bandwidth for everyone who wants it.

That you don't realize this would be radio is a good indication, like someone
else suggests, that there is no solution for you because you don't have
the grounding to go anywhere with it.
