   The 100 mW "rule" was dropped in the late 1960's.  Field strength at a   
   specified distance rules have been in place ever since for intentional   
   radiators.  Unintentional radiators are allowed considerable power when   
   operating on ISM (Industrial, Scientific, and Medical) bands.  Typical   
   frequencies are 13.56 MHz, 27.12 MHz, 915 MHz, and 2450 MHz.  ISM usage   
   is defined in Part 18 of the FCC rules, whereas unlicensed communication   
   devices are covered by Part 15.
