The modulation method of the radio equipment that uses
emissions of a frequency of higher than 3.456 GHz to 3.6
GHz, higher than 5.85 GHz to 5.925 GHz, higher than 6.425
GHz to 6.57 GHz, higher than 6.87 GHz to 7.125 GHz, higher
than 10.25 GHz to 10.45 GHz, higher than 10.55 GHz to 10.68
GHz, or higher than 12.95 GHz to 13.25 GHz among the radio
equipment specified in the preceding paragraph shall be
orthogonal frequency division multiplexing (OFDM) in addition
to the modulation method prescribed in item 2) of the preceding
paragraph. In this case, when a signal for contact or control
of equipment is also transmitted, a carrier which is 4PSK-modulated
by the said signal shall be used, and when a signal for
controlling the frequency on the receiving side is also
transmitted, an unmodulated carrier shall be used as the
said signal.
