The
Federal Communications Commission, abbreviated as FCC is a United States
government agency, created, directed, and empowered by Congressional statute,
and with the majority of its commissioners appointed by the current president.
The FCC is an important factor in US telecommunication policy, it took over
wire communication regulation from the Interstate Commerce Commission. The
FCC's mandated jurisdiction covers the 50 states of the United States of
America, the District of Columbia, and U.S. possessions. Due however to
close geographic proximity to the United States, the FCC also provides varied
degrees of cooperation, oversight, and leadership for similar communications
bodies in other countries of North America.
All electronic devices with unintentional radio-frequency radiators that
are entering the commercial market in the United States are regulated by
the Federal Communications Commission or FCC if they employ clocks or oscillators,
operate at a frequency of greater than 9 kHz and use digital techniques,
which includes almost every product that contains a microprocessor. If an
unintentional radiator is not designed with proper control in terms of grounding
and shielding, the radiated energy levels of such radiator could be high,
causing unwanted interference with other devices. Under FCC’s rules and
regulations, Title 47, Part 15 Subpart B in specific, FCC has setup specific
requirements, including two categories, Class A and Class B. Class A Device
is a device marketed for use in an industrial or business environment and
not intended for use in the home or a residential area, whereas Class B
Device is the device marketed for use in the home or a residential area.
Here are some examples of devices included in FCC categories: personal computers,
calculators, printers, modems, a large number electronic games and similar
devices that are sold to the general public.
