Post your comments for Wi-Fi-Blocking Wallpaper Keeps Your Signal In, Intruders Out here

[deokanon]

Can you imagine a WPA 2 encryption combined with a listing of permitted devices'mac addresses is not sufficient in this day and age... I mean I am not even being sarcastic here. If I ever live somewhere in downtown area I will have to purchase this kind of technology to protect myself.

They should install this in public schools where kids play on their cell phones all day.

When I bought this home in1985, it needed to have its aluminum wiring and insulation added. The walls were mouldy at the baseboard so I have already sheilded the walls with foil backed insulation rolls when the sheet rock was replaced, grounded at the outlets. I operate a ham radio station and the grounding help to create somewhat of a Faraday cage. The signal strength of the routers used is not adequate outside the walls. The wallpaper is a great idea and this is something that I'm sure the theather, church and many other public places where cell phones are not desired, can retrofit easily with low cost. I'm not in favor of active jamming as that can disrupt more than just cell phones and create more problems than it solves.

Are you kidding? Wait 'till the tin foil headgear people hear about this, it'll be the all the rage.

I missed that.

Thanks

So it turns out that tinfoil headgear actually boosts antenna gain at frequency bands allocated to the US government.

Based on the conclusions of the cited report, paranoid types might suspect that the gum'mint developed this decorative faux shielding in order to promote its widespread use.

Or you could just use the WiFi blocking paint that PCworld talked about a couple of years back
