I fully agree that the law is convoluted and may not reflect the true intentions of the authors (who probably didn't fully understand exactly what they were trying to ban, or how to properly describe it).

The FCC has a mandate to regulate ALL spectrum use. Some use is explicitly licensed, other use is "free for all" within certain set aside frequency bands. The above reference to "unlicensed wireless services" would likely include all spectrum use within the bands set aside as "free for all". Wifi and bluetooth most likely fall into that (I'm sure the fed thinks they do...maybe you could argue that with some expensive legal help).

Wifi, bluetooth, cordless phones, RC airplanes, etc are NOT unregulated. They are regulated such that:

1) They have to stay in the bands allocated for unlicensed use.

2) The devices have to meet certification criteria related to power output and sidebands, basically limiting the range and bleed-over into other bands.
