Enabling and Disabling World-Mode
You can configure the access point to support 802.11d world mode or Cisco legacy world mode. When
you enable world mode, the access point adds channel carrier set information to its beacon. Client
devices with world mode enabled receive the carrier set information and adjust their settings
automatically. For example, a client device used primarily in Japan could rely on world mode to adjust
its channel and power settings automatically when it travels to Italy and joins a network there. Cisco
client devices running firmware version 5.30.17 or later detect whether the access point is using 802.11d
or Cisco legacy world mode and automatically use world mode that matches the mode used by the access
point. World mode is disabled by default.
World mode is not supported on the 5-GHz radio.
Beginning in privileged EXEC mode, follow these steps to enable world mode:
Use the no form of the command to disable world mode.

Enable world mode.
• Enter the dot11d option to enable 802.11d world mode.
– When you enter the dot11d option, you must enter a
two-character ISO country code (for example, the ISO
country code for the United States is US). You can find
a list of ISO country codes at the ISO website.
– After the country code, you must enter indoor,
outdoor, or both to indicate the placement of the
access point.
• Enter the legacy option to enable Cisco legacy world
mode.
Note Aironet extensions must be enabled for legacy world
mode operation, but Aironet extensions are not
required for 802.11d world mode. Aironet extensions
are enabled by default.
