Paint Provides Network Protection

thefickler writes "Forget WEP and WPA; I'm switching over to the EM-SEC Coating System, a recently announced paint developed by EM-SEC Technologies that acts as an electromagnetic fortress, allowing a wireless network to be contained within painted walls without fear of someone tapping in or hacking wireless networks. The EM-SEC Coating System is clearly the most secure option aside from stringing out the CAT5, and can be safely used to protect wireless networks in business and government facilities."

      It's illegal to actively block frequencies (by using a jammer, for instance), but not illegal to passively block frequencies (by creating a Faraday cage, like this paint is trying to do).

      Cell phones are all lower frequency
      From 800 MHz to 1.9 GHz
      (and something about 450MHz, but that isn't common)

      Don't you think they can limit their product to 2.4 GHz +/- 500 MHz? No. That's hard enough to do with a mechanical Faraday type arrangement, much less paint. Don't you think it'd be better to understand the physics of EM radiation before you make silly presumptive comments?

  9. Coatings are Becoming More Popular by emilyridesabmx · · Score: 5, Interesting

    I work in a pretty specialized architecture firm, and some of our clients are slightly paranoid to say the least (Ting foil hats? More like Tin Foil Ceremonial Headpieces...) and we are working on a project that has a room that is set up to ward off an EMP during the coming apocalypse. I'm not kidding. The 'Safe Room' in this building is totally shielded, you can't get any type of electronic signal in or out. Coatings like the paint mentioned in the article are becoming more and more and common,and I think we're going to see a lot more multi-use coatings like this in the future. At the moment, they are extremely expensive, but as the price drops, this will become a pretty standards feature in a lot of new constructions where buildings are put up in close proximity to each other and interference tends to be a big problem. Conversely, you can always just get a few rolls of Reynolds Wrap and poster your walls with that.

    1. Re:Coatings are Becoming More Popular by customizedmischief · · Score: 5, Interesting

      I have a paranoid client who would use a product like this in the real world as well. Their house was constructed with gypsum panels with aluminum backed paper. All of the custom cabinetry is steel. The windows are something special too. The place is cool as hell. No, I can't get a cellphone signal in there. The place was designed to keep the radio waves out, not in, but it works both ways. I wouldn't put that place up against a determined nsa van, but it is really impressive what the gets blocked. As far as I know, none of those panels are intentionally bonded to ground, so it could be a lot better.

      This place has a "safe room" too, but it's just the place where they put new plastic products coming into the house for a month or two to let them outgas most of their VOCs. I get my chuckles about it, and I'm not allowed to go there if I put on deodorant that day, but I have to admit that the air quality in there is superb. Placebo or not, I always feel better after working there for a day.

  14. Typical attempt to get government to spend oodles by gjuk · · Score: 4, Insightful

    Governments have a great habit of wasting money by trying to dot every 'i' and cross every 't'. Of course, you can never achieve perfection, but their endless quest does have the effect of each extra step costing enormous amounts of extra money with minimal incremental benefit.

    In this case: WPA (and many other layers of encryption) = free. Painting a building with special paint = £$massive.

    What's scary is that someone from a government department will mandate this kind of tosh - and suddenly every government building (including leisure centres) will have to have it.

    Of course, the irony is that - once they get paint like this, people will feel overly secure - reduce the more sensible types of encryption - and then leave the loading bay doors open, right next to a wireless repeater, pouring forth their unencrypted secrets.

    Do you think it is 'cool' when you have a problem and your doctor is notified via SMS while they're watching a movie in a cinema or having dinner in a restaurant that uses this uber-paint? You know, if the tired old "what if your doctor blah blah blah" is the only thing anyone can ever come up with against cell blocking, then I say who the fuck cares? There's generally nothing one doctor can do in an emergency that another can't, and in those very rare cases where there is, then those doctors need to stay out of EM blocked places, 'kay? The "doctor getting an SMS" case is already such an extreme outlier that it really has no business dictating policy that affects everyone. Go ahead, tell me you hope my mother has a terrible cheese-grater accident and needs the services of the one and only "grated face restoration" expert, but that he's watching the entire Lord of the Rings trilogy in a theater covered with this EM paint. I'm willing to take that billion to one chance.
