Apr 22, 2010 · How Many non overlapping Channels on 802.11N. Right I’ve heard that there are 9 non overlapping channels on 802.11N but I know from the stuff I’ve done on g that that only has 3 sets of 3 non overlaping ie 1,6,11 or 2,7,12 etc. As N use 40mhz rather than 20mhz how can it fit the extra channels in. Does it use the 5Ghz range in a unique way and
802.11b/g Channels. Although 802.11b and 802.11g use the 2.4GHz frequency band for signaling, the frequency is divided up into 11 channels for use in US and Canada (some countries allow as many as 14 channels). Table 1 shows the channel frequencies supported in the US and Canada.
Each channel is 20 MHz wide. *2 – These are typical acheived rates. Actual throughput will depend upon various factors such as the manufacturer and model, environmental factors, whether 20 MHz or 40 MHz channels are utilized, if security is enabled and whether all clients are 802.11n or a mix of 802.11a/g/n.
Aug 18, 2010 · How many non overlapping channels are there in 802.11a ? I’m finding various answers to this question. On page 106 of the The CCNA Wireless Certification it says “802.11a supports anywhere from 12 to 23” That seems very vague.

2.4 GHz 802.11 channels. When using 802.11 to provide Wi-Fi solutions for offices, general use hotspots, or for any WLAN applications, it is necessary to ensure that parameters such as the channels are correctly set to ensure the required performance is achieved.
Larger bandwidth channels: Bandwidth channels are part and parcel to spread-spectrum technology. Larger channel sizes are beneficial, because they increase the rate at which data passes between two devices. 802.11n supports 20 MHz and 40 MHz channels. 802.11ac supports 20 MHz channels, 40 MHz channels,
In 802.11n, bonding utilizes two adjacent Wi-Fi channels simultaneously to double the bandwidth of the wireless link compared to 802.11b/g. The 802.11n standard specifies 300 Mbps theoretical bandwidth is available when using channel bonding.
Channels operating with a width of 40 MHz are another feature incorporated into 802.11n; this doubles the channel width from 20 MHz in previous 802.11 PHYs to transmit data, and provides twice the PHY data rate available over a single 20 MHz channel.
