channels 1, 6, and 11 are the non-overlapping channels for 2.4 GHz Figure 4.6. Again,
you can use “Scan network” to see which channels are already occupied.
 Bandwidth: when 40 MHz is used, AW5500 will double the channel width to 40 MHz as
compared to the standard 20 MHz to transmit its data; this is not recommended for
802.11b/g/n since it will leave only one non-overlapping channel for other APs. HT40 (40
MHz), is recommended for 802.11a/n because it offers a wider frequency range and it is
easier for AW5500 to find empty channels as well.
