Not true. There are unlicensed bands of various widths and power and
modulation requirements. Some of them might require periodic broadcast of a
station identifier though ;-)
I seem to recall when I was browsing the FCC regulations, that in some
cases one did not even require a license to transmit (within certain
parameters) on commercial radio station frequencies, if one was
transmitting using "sideband" technologies.
The details of what can or cannot be done unlicensed in areas under
FCC jurisdiction are quite complex. For example, a regulation that
says that you can't transmit beyond a certain power on a certain
frequency band within a certain distance of a [named] Navy weather
station, is still a regulation that permits transmission in that
frequency range provided one is far enough away from that particular
weather station. Sometimes the licensing requirements are tied to
which polarization one is using.
It might take a bunch of research, some hair-splitting, and some
custom electronics, but WiFi is NOT the only spectrum that can be used
for data transmission unlicensed.
