Configuring Country Codes
Controllers and access points are designed for use in many countries with varying regulatory
requirements. The radios within the access points are assigned to a specific regulatory domain at the
factory (such as -E for Europe), but the country code enables you to specify a particular country of
operation (such as FR for France or ES for Spain). Configuring a country code ensures that each radio’s
broadcast frequency bands, interfaces, channels, and transmit power levels are compliant with
country-specific regulations.
Generally, you configure one country code per controller, the one matching the physical location of the
controller and its access points. However, controller software release 4.1 or later allows you to configure
up to 20 country codes per controller. This multiple-country support enables you to manage access points
in various countries from a single controller.
Note
Although the controller supports different access points in different regulatory domains (countries), it
requires all radios in a single access point to be configured for the same regulatory domain. For example,
you should not configure a Cisco 1231 access point’s 802.11b/g radio for the US (-A) regulatory domain
and its 802.11a radio for the Great Britain (-E) regulatory domain. Otherwise, the controller allows only
one of the access point’s radios to turn on, depending on which regulatory domain you selected for the
access point on the controller. Therefore, make sure that the same country code is configured for both of
the access point’s radios.

Guidelines for Configuring Multiple Country Codes
Follow these guidelines when configuring multiple country codes:
•
When the multiple-country feature is being used, all controllers intended to join the same RF group
must be configured with the same set of countries, configured in the same order.
•
When multiple countries are configured and the radio resource management (RRM) auto-RF feature
is enabled, the auto-RF feature is limited to only the channels that are legal in all configured
countries and to the lowest power level common to all configured countries. The access points are
always able to use all legal frequencies, but non-common channels can only be assigned manually.
