[sci.electronics] FCC freq regs

johnd@sco.COM (John Dubois) (12/08/89)

     What range of frequencies does the FCC actively regulate?  I know they
have authority to regulate "DC to daylight", but what are the max and min
freq's you can use without any concern for FCC compliance?  I'm actually most
interested in the low end, since I'm working on a project that will require
the use of an unshielded signal carrier.  How does radiated power enter into
the regs?

     The FCC has jurisdiction over radio waves, defined as "Electromagnetic
waves of frequencies arbitrarily lower than 3,000 GHz, propagated in 
space without artificial guide."  Source: 47 CFR Ch.1, section 2.1.

     FCC jurisdiction thus ends somewhere in the long infrared.  Optical
communication systems do not require FCC licencing.  Safety of optical
emitters is regulated by the Department of Health and Human Services.
