A power cube (CP-PWR-CUBE-4=) is required when utilizing the Cisco Unified IP Phone 9971 in Wi-Fi mode.
Note: Channels 120, 124, 128 are not supported in the Americas, Europe, or Japan, but may be in other regions around the
world.
802.11j (channels 34, 38, 42, 46) and channel 165 are not supported.
Channel 14 for Japan is not supported on the newer Cisco Access Points.
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 IP Phone 9971, then it is required to enable 802.11d. The Cisco Unified IP Phone 9971 uses 802.11d
to determine which 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 IP Phone 9971 will passively scan DFS channels first before engaging in active scans of those channels.
If using 2.4 GHz (802.11b/g) and 802.11d is not enabled, then the Cisco Unified IP Phone 9971 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:
