I thought baby monitors were at 40-50 Khz. I didn't realize that the 2
GHz band was so widely used (will have to see what ours are at).
Also, you said it is "unlicensed." It is, apparently, set aside for
these purposes only; unallocated spectrum is available to amateur radio
operators.
In the GHz range, amateurs can operate (in all modes, all licenses
except Novice) at 10.0-10.5 GHz; 24.0-24.25 GHz; 47.0-47.2 GHz;
75.5-81.0 GHz; 119.98-120.02 GHz; 142-149 GHz; 241-250 GHz; anything
above 300 GHz. See what I mean about frying your brain? :-)
Don't stand too close to that antenna :-)
