Different regions around the world use slightly different frequencies for the various wireless interfaces available on your average Linux portable device such as WiFi, Bluetooth and other such interfaces. Overall they fit into larger categories such as 2.4Ghz, 5Ghz etc, but within each of these larger buckets countries have a subset of the frequencies, generally referred to as channels available. For example the 2.4Ghz range used by most WiFi and Bluetooth interfaces has potentially up to 14 channels available, the default is a generic “world” region which uses 11 channels that are available in all regions, but a lot of regions have 13 available for use, and some even have 14. The situation is similar on the 5Ghz range, and no doubt on the higher frequencies now becoming available too.
