s and client devices that meet the different regulations enforced in various parts of the world. The amendment has been incorporated into the published IEEE 802.11-2012 standard. 802.11d is a wireless specification for operation in additional regulatory domains. This supplement to the 802.11 specifications defines the physical layer requirements: * Channelization * Hopping patterns * New values for current

attributes * Future requirements to extend the operation of 802.11 WLANs to new regulatory domains (countries). The current 802.11 standard defines operation in only a few regulatory domains (countries). This supplement adds the requirements and definitions necessary to allow 802.11 WLAN equipment to operate in markets not served by the current standard. These are anything other than Americas or FCC, Europe or ETSI, Japan, China, Israel, Singapore, Taiwan. As of January 1, 2015, the
