Here you specify how and to what extent the AP sets the channel bandwidth for the first physical WLAN interface.
By default, the physical WLAN interface automatically determines the frequency range used to modulate the data onto the carrier signals. 802.11a/b/g use 48 carrier signals in one 20-MHz channel. Doubling the frequency range to 40 MHz allows 96 carrier signals to be used, resulting in a doubling of data throughput.
802.11n can use 52 carrier signals in a 20-MHz channel for modulation, and even up to 108 carrier signals in a 40-MHz channel. The use of the 40 MHz option for 802.11n therefore means a performance gain of more than double.
