2.4 GHz WLAN/Wi-Fi Technology (802.11 b/g/n) uses the frequency band from 2401 to 2484 MHz. This bandwidth is divided among 14 channels. Each of the WLAN / Wi-Fi Channels are spaced 5 MHz apart, except the last two channels which are spaced 12 MHz apart. Most of these channels (Channel 1 to Channel 11) can be used across the globe, except channels 12, 13 and 14. Channel 12 (2456 - 2478 MHz) and Channel 13 (2461 - 2483 MHz) are not allowed in North America, whereas Channel 14 (2473 - 2484 MHz) can only be used in Japan.
