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 (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.
