IEEE 802.11d

The IEEE 802.11d standard of the Institute of Electrical and Electronics Engineers (IEEE) is also often referred to as "World Mode" and regulates the technical differences of the wireless LAN in different countries and regions. This includes, among other things, the number and selection of channels that are approved for the use of WLAN in a country. The selection of the basic technology is also regulated, i.e. whether IEEE 802.11 a, h, b or g may be used. Thanks to IEEE 802.11d, the end user only has to specify his current location by selecting a country or region; the device then works with the respectively approved standards.
