802.11 Wireless Routing

[Dogma]

When the book talks about non-overlapping channels in Chapter 12, what are the benefits compared to overlapping channels? Does Wi-FI use overlapping channels as well, or just non-overlapping? I'm guessing the non-overlapping benefits are just interference reduction. Can someone shed a little more light on this, with regards to channels being used in 802.11b/g?

Hello,
it is very simple: If the channels overlap they disturb each other!

So your gaol is to use non overlapping channels, usually 1, 6 and 11!

Tore, thanks again for your post.

You do not want to cause interference on your wireless network, so you do not want to have two access points configured in the same channel, for example, channel 1. These are the same frequency and would cause problems on your network.

The channels typically used to configure access points are channels 1, 6 and 11. However, if they are not close to each other and do not "see each other", then you don't need to worry about the channel. You would worry about the channels in AP's if they are in sight of each other, or you want to set up an extended service set (ESS). An ESS is used so users can roam from one area of the office to another without losing connectivity.

You can do this by setting up mutiple AP's, but not in the same channel if they are in wireless sight of each other.

Cheers!
