SOHO wireless is just too cheap and too prevalent for many of the things that you would think about to "fix" the "congestion". I liked the idea of some type of fuzzy logic program (Just for the novelty of it)built into the residential wifi routers that would do a scan of the area and then choose an appropriate channel to operate on. It would have to then be like a wasp protecting the nest and calling that channel it's own and not change or rescan unless power were lost. The next router to be plugged in would scan the area and choose another channel. I guess the criteria would be if the router finds other routers close by they could not use a channel already being used if the signal strength is above 20-30. Not really able to set a criteria for a link quality as you would have to have routers connecting to other routers to find out that percentage. That would be quite a mess.
For the technology we have now, adding more channels to the band would be a great start.
You could always do like I did. Move away from the urban jungle and out to the sticks. Make sure your neighbors are all retired people and they don't spend the $$ on the neat little gadgets with wifi built into them. I have 2 APs near my house. Both with insignificant signals. So it's all good.
