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:

A – FCC (Americas)

E – ETSI (Europe)

I – Israel

J – TELEC (Japan)

S – Singapore

T – Taiwan

1. That the absence of these regulatory domain designators does not necessarily mean that the product is not certified for use in the listed country.

Instead a different regulatory domain applies for the country. Please check your country compliance and the applicable regulatory domain designator

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:
