Channels Overlap

[LoneStarStumble]

I had been told that with 802.11b channels 1, 6 and 11 did not overlap with each other. I did some research and found out that the bandwidth of 802.11b channels are 30 MHz. So I did a little calculating. I learned that channel 6 overlaps with all of the 802.11b channels. So in theory this would be the most undesirable channel from an interference standpoint. Now I did this late at night so I'm sure I must have made a mistake. Someone tell me where I've gone wrong.
