Beware of Japanese paint that blocks your air cards
Have you found a neighbor with an open internet connection that permits you free connection waiting for the spread of fast air cards 4g? Now, you will have to reckon a new barrier: an high-tech paint that protects fast wireless router connected to internet from the thief of internet signal.
Scientists at the University of Tokyo have discovered a new material that can block wireless communication radio, a real wave-absorbing dye that is much more efficient than similar ones available so far.
If in fact the current commercial products are not able to go beyond 50 GHz, WiFi communications can make use of (micro) waves that reach up to 100 GHz and beyond on the electromagnetic spectrum. At this point there is no paint that can defend your wireless signal. Maybe with an office builded into a anti-double-atomic layer bunker you can protect your signal from any outside device equipped with an aircard.
Paint Japanese, however, is able to overcome the above limitations, an oxide compound containing aluminum-iron that can resonate at the same frequency of the microwave WiFi more stringent, by blocking all attempts to access and successfully isolating the environment. According to the measurements of the researchers, the paint is able to inhibit communications traveling up to 182 GHz, more than four times the nominal capacity of absorption of ferrous oxide standard used in products currently on the market.
And there’s more: according to Shin-ichi Ohkoshi and his team, produce the paint it’s cheaper. Scientists have commissioned an outside company to produce a sample of 100 kilograms, the manufacturing costs didn’t exceed 14 dollars each kilo, in practice as a pack of low-tech paint.
Check with your air cards if there is an internet signal outside. If not, maybe you are the first victim of the japanese high tech paint.
