Faraday cage made with wallpaper

A French firm has a new product, wallpaper with embedded Wi-Fi blocking.

Unfortunately I don't speak French; perhaps someone else could summarize the article for us?

You pretty much summed it up: "A French firm has a new product, wallpaper with embedded Wi-Fi blocking".

Not much more to say, except that it can also block cell phones.

Yet 3rd paragraph is not really clear : It is mentionned that you can block up to three frequencies. My guess is that you can buy a specific wallpaper designed to block certain frequencies (mobile phone, wifi), but you cannot "retarget it" on the fly.

Regarding price, it should cost much more than middle-range wallpaper.

The article doesn't go into technical specification. It would be great to have a link to the actual press release from the designer (a french engineering school).

OK if you want to stop wifi getting into your room, don't suppose its such a good idea if you want to prevent wifi getting out. The effect will be like sitting in a low power microwave oven

what a useless idea ...

The first window or door that comes along punches a massive hole in the shield ... back to the drawing board boys ... this is a screen door on a submarine...

Not only that, in many places it is illegal to block cellphone communications. It may be allowable in private homes but it would limit its use in businesses etc.
