I know many network cards can do "site surveys" and give you an idea of what's around, but this was a revelation to me. Geek that I appear have become, I surveyed my house, using various channels. A couple of surveys are attached (I used the grid for simplicity, but you can enter a plan of your floorspace, for greater accuracy).
