World Mode (802.11d)
World Mode allows a client to be used in different regions, where the client can adapt to using the channels and transmit powers
advertised by the access point in the local environment.
If using the Cisco Unified Wireless IP Phone 7925G World (-W) model, the Cisco Unified Wireless IP Phone 7925G-EX or
Cisco Unified Wireless IP Phone 7926G model, then it is required to enable 802.11d. The Cisco Unified Wireless IP Phone
7925G gives precedence to 802.11d to determine the channels and transmit powers to use and inherits its client configuration
from the associated access point.
Enable World Mode (802.11d) for the corresponding country where the access point is located.
Some 5 GHz channels are also used by radar technology, which requires that the 802.11 client and access point be 802.11h
compliant if utilizing those radar frequencies (DFS channels). 802.11h requires 802.11d to be enabled.
The Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G will passively scan DFS channels first before engaging in
active scans of those channels.
If 802.11d information is not available from the access point, then the Cisco Unified Wireless IP Phone 7925G (-A, -E, -P)
model uses the locally configured regulatory domain. If the Cisco Unified Wireless IP Phone 7925G -A, -E or -P model is
taken to another country, where the access point uses a different regulatory domain, then 802.11d will be required for the Cisco
Unified Wireless IP Phone 7925G to operate successfully.
If using 2.4 GHz (802.11b/g) and 802.11d is not enabled, then the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and
7926G can attempt to use channels 1-11 and reduced transmit power.
Note: 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:
