Specify the radio frequency to use for a given interface. There are
a small number of different channels available use in different geographical
areas. Known values are 3 (2422Mhz) for the United States, 11 (2462Mhz)
for France and 14 (2484Mhz) for Japan, however the NIC may accept any
channel number between 0 and 14. If an illegal channel is specified, the
NIC will revert to its default channel. For NIC sold in the United States,
the default channel is 3. Note that two stations must be
set to the same channel in order to communicate.
Set the radio frequency of a given interface. The
.Ar frequency
should be specfied as a channel ID as shown in the table below. The
list of available frequencies is dependent on radio regulations specified
by regional authorities. Recognized regulatory authorities include
the FCC (United States), ETSI (Europe), France and Japan. Frequencies
in the table are specified in Mhz.

If an illegal channel is specified, the
NIC will revert to its default channel. For NICs sold in the United States
and Europe, the default channel is 3. For NICs sold in France, the default
channel is 11. For NICs sold in Japan, the only available channel is 14.
