Keep Wi-Fi Out, Or In, With This Signal Blocking Wallpaper

Sure, you can password protect your Wi-Fi router, but you can’t exactly keep your precious Internet from seeping out of your house or apartment and over to your neighbors. Or can you? Thanks to some new-fangled wallpaper due to go on sale by the Finnish company Alhstrom in 2013, you can make your residence Internet-tight, keeping all your Internet in and everyone else’s Internet out. After all, you’ve got to be conservative with your limited supply of Internets, right?

Using special patterns of silver crystals, the wallpaper forms a wall that can actually block signal intrusion — from either side — unlike your regular walls. I know silver crystals sound expensive, but by all reports, the wallpaper won’t be that much more expensive than your normal wallpaper, and if the design irks you a little bit, don’t worry; you can obscure it with paint. After all, what’s the worst that could happen? You accidentally double-block Wi-Fi signals?

If you really don’t like wallpaper, you can always pick up some Wi-Fi blocking paint, but both solutions have their holes. You still need a Wi-Fi blocking floor, for instance, and a Wi-Fi blocking ceiling. Until we get Wi-Fi blocking carpets and Wi-Fi blocking plaster, your little Wi-Fi bubble remains incomplete. You could just wallpaper the floor and ceiling, but allow me to suggest a WPA2 encrypted network with a strong password. Trust me, it’s easier that way.
