Wi-Fi Blocking Paint

* Here is another useless product to make you say, hmmm.  Developed at the University of Tokyo, the first paint that can block radio frequencies from being broadcast outside of your happy abode, according to university sources: “the paint is said to be the first that can block radio frequency in higher spectra where Wi-Fi and other higher-bandwidth communications occur rather than just low-frequency wireless like FM radio. Most Wi-Fi technologies operate at 2.4GHz; the Tokyo paint can reportedly block frequencies all the way up to 100GHz, with a 200GHz-blocking paint now in the works.” 

Other applications include churches, movie theaters, concert halls, conference rooms, class rooms and offices to keep cell phone signal at bay.  No more ringing, glowing phone screens at movies and concerts, cheating on exams will no longer be possible, and  the wife can’t call in the middle of a meeting to let you know that your kid is not really sick (it’s just an excuse to get out of the meeting).  Look at all the great applications for this neat new product.  However, according to most engineers - if security is the issue, most, if not all Wi-Fi systems have:  "Surely the thought of having to redecorate a building in order to provide Wi-Fi security is more costly and complex than the security functionality available in even the cheapest of Wi-Fi access points..."

What makes the paint work?  Simply, the paint contains aluminum-iron oxide particles.  If you are looking for greater security, don’t waste your time.  Yet, other applications, such as theatres and class rooms, may make it well worth the expense, when and if you need to repaint, or in new construction.

Other than the report from the University, no testing, etc. has been done on this product, making it a developed, un-proven idea.  Let’s wait and see where this will go. Until the paint is available, just get a copy of “Paint your Wagon,” featuring Lee Marvin and Clint Eastwood, and enjoy at night at home with no cell phones or Wi-Fi.

* DISCLAIMER: This author found the paint, and it's uses interesting. However, in no instance is the author recommending this product, or the usage of frequency blockers of any kind.
