World Mode (802.11d)
If you are using the Cisco Unified IP Phone 9971 in the World Mode, you must enable World mode
(802.11d). The Cisco Unified IP Phone 9971 uses 802.11d to determine which channels and transmit
powers to use and inherits the client configuration from the associated access point.
Enabling World Mode (802.11d) may not be necessary if the frequency is 2.4GHz and the current access
Note
point is transmitting on a channel 1-11.
Because all countries support these frequencies, you can attempt to scan these channels regardless of
supporting World Mode (802.11d). For the countries that support 2.4GHz, see
9971 Wireless LAN Deployment
Enable World Mode (802.11d) for the corresponding country where the access point is located. World
Mode is enabled automatically for the Cisco Unified Wireless LAN Controller.
World Mode must be enabled manually for Cisco Autonomous Access Points using the following
commands:
Interface dot11radio X
world-mode dot11d country US both
