New Paint to Block Wi-Fi SignalsMonday, January 26, 2009
This would be a perfect paint to use if you’re living in an appartment building and you’re worried about your wireless internet being stolen.
This particular paint was started by a team of researchers from the University of Tokyo. They have developed an aluminium-iron oxide that blocks radio frequencies up to four times beyond existing anti-RF technologies. The paint puts out a magnetic field that resonates at the same frequency as the electromagnetic wave (in this case, a radio frequency) you’re looking to block.
