Regulatory Domains
Regulatory domains are used to distinguish groups of countries that adhere to the same or similar regulations for
radio usage with regards to available channels and transmit power. Cisco Aironet radio products are set at the factory
to allow a particular channel set and maximum transmit power and are reflected in the part number as the single
character following the model number (for example, in AIR-AP1231G-A-K9, the regulatory domain is represented
by “-A-”. Customers must select the correct regulatory domain that corresponds to their particular country when
choosing a radio module for use in their access point or when choosing a preconfigured bundle.
The Cisco Aironet 1200 Series access point is certified for use in many countries around the world, but has not been
approved for use in all countries. Please refer to the following URL for current worldwide approval status of the
Cisco Aironet 1200:

The following table identifies the regulatory domains choices available for the radio modules:
Antennas
The 2.4 GHz radios for 802.11b and 802.11g support a flexible set of Cisco Aironet omnidirectional and directional
antennas that can be mounted on walls, ceilings or on masts. The 2.4 GHz radio does not come with antennas; the
antennas must be ordered separately. Note that the Cisco Aironet 1200 Series access point is certified for operation
only with Cisco Aironet antennas. To ensure regulatory compliance, select Cisco Aironet antennas for use with the
1200 Series access point.
The 5 GHz radio for the 802.11a is designed with an integrated diversity antenna system. Auxiliary 5 GHz antennas
are not required and are not available. A complete Antenna Reference Guide is available to assist users in selecting
the proper antenna for specific deployment requirements:
