3 party antennas are not supported, as there is no interoperability testing performed against 3
Distributed Antenna Systems (DAS) and Leaky Coaxial Systems.

Note: The Cisco 1130, 1140 and 3502i series access points are to be mounted on the ceiling as they have omni-directional
antennas.

Phone Models and Localization

Phone Models

The Cisco Unified IP Phone 9971 model requires an 802.11d enabled access point.
Below are the channels that are supported.
Part Number Band Range
CP-9971-K9 2.412 – 2.484 GHz
5.180 – 5.240 GHz
5.260 – 5.320 GHz
5. 500 – 5.700 GHz
5.745 – 5.805 GHz
Note: 802.11j (channels 34, 38, 42, 46) and channel 165 are not supported.

World Mode (802.11d)

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.
When using 802.11a, enable 802.11d to discover which channels can potentially be used in the network. Specifically, for
802.11h support, the phone passively scans some of the 5 GHz channels (DFS) first before actively scanning any network
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:
