Not a clue. At various times it appears there are a couple of networks that do this high output power thing. I'm just in a middle class neighborhood, don't really know much about what I'm seeing. My network router has the capability of having my account and a guest accout simultaneously. This way I can have different passwords to allow guests to sign on, which is a cool thing. My home PC's use my primary account, and connect using both bandds. As you can see, I'm alone on the 5GHz band, with a lot of competition on the 2.4 GHz band.
