802.11d is an amendment to the IEEE 802.11 specification that adds support for "additional regulatory domains." This support includes the addition of a country information element to beacons, probe requests, and probe responses. The country information elements simplify the creation of 802.11 wireless APs and client devices that meet the different regulations enforced in various parts of the world.
To add the country information element in beacon frames, the 802.11h options "Advertise TPC capability" and "Enable CSA" must be enabled in the dot11g/a radio profile in Aruba.
