Probably works pretty good actually. Probably based off similar stuff that we use in military applications for EMI shielding. Basically it’s just paint with metal-flake in it; either berillium copper, aluminum, or something else similar that basically creates an EMI shield. ---

I hope people realize that they should only paint exterior walls. Should you paint and entire room, your wireless access would be useless there. ---

I assume it works since I first heard about it in a story about a woman who was allergic to EM waves. ---

its so silly. Wifi only goes what 100 feet. Ok thats fine. If you setup a wpa network and change the preshared key once in a while I wouldnt worry about it. ---

I dont think they’re metal chips more than metal strands that pick up the 2.4Ghz signal. Kinda like a chain link fence (which will capture/block 2.4Ghz) ---

youre not trying to pick up the signal, I would assume you either want to reflect/scatter the signal or absorb enough energy to drop the wavelength. Sorta the same thing if you think about it. Wouldn’t this disrupt cordless phones/cells and make wireless useless without line of site to the source? ---

it works just like a fariday cage… Basically you just make a metal box around something and it shields any sort of electrical waves from passing through it; it conducts the energy to ground typically. Thus the paint is just an electrically conductive paint with a low area surface resistance. Same kinda thing the use on the Stealth Fighter, F-22, and JSF to conduct the radar energy away to reduce the amount bounced back. ---
