Noise and Interference in a Big City
I live in a major metropolitan area and see an extraordinary amount of Access Points when my laptop is near a window (sometimes 20-30 APs).

My question is, do the other Access Points cause alot of interference with each other if they're on the same channel?

If so, would a higher gain directional antenna aimed at a specific direction remove some of the interference problems (because it would be looking in a smaller targeted area with more concentrated power versus an omni antenna built into most laptops)?

I'd like to understand the effects of interference and what directional/higher gain does in this big city scenario.

Thanks

this would be a good time to do a site survey and see what channels are in use in your area so you can pick a different one. Default for most is channel 6 so choosing a different one is good
