Information About 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 within that regulatory domain (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.
Information About Japanese Country Codes
Country codes define the channels that can be used legally in each country. These country codes are available for Japan:
JP: Allows only –J radios to join the controller
J2: Allows only –P radios to join the controller
J3: Uses the –U frequencies, but allows –U, –P, and –Q radios to join the controller
J4: Allows 2.4G JPQU and 5G PQU to join the controller.
See the Channels and Maximum Power Settings for Cisco Aironet Lightweight Access Points document for the list of channels and power levels supported by access points in the Japanese regulatory domains.
