WLAN country codes D
D.1 Restrictions in WLAN use
Not all countries allow full use of all channels. Also, some countries do not allow operation
according to the 802.11g standard. Therefore the WLAN interface must be set up to the
right country code.
By default, the SBU is set up to the US country code that allows the WLAN interface to
operate according to the 802.11b and 802.11g standards on the channels 1 to 11. If the
equipment is used in the countries listed in
Table D-1 on page D-2, the default country
code “US” can be used. In other countries the country code “other countries” must be used,
allowing the interface to operate only according to the 802.11b standard on channels 4-9.
To set up the country code, use the WLAN page of the built-in web interface in the SBU. For
further information see
WLAN interface (option) on page 6-22.
