(from a press release) "CPFilms Inc., a unit of Solutia Inc., announced today that it is introducing LLumar® Signal Defense Security Film, a high-tech clear window film for businesses and high net-worth individuals looking to secure and protect the confidentiality of their wireless and other “free-space” electronic communications. The film is ideally suited for industries where securing confidential information and protecting data is paramount – such as retail, healthcare, and the financial services industry. Patented technology built into LLumar Signal Defense film reduces electronic signal leakage through windows, a building’s point of least resistance, by serving as a transparent barrier that allows light to pass through, while minimizing transmission of wireless (WiFi), radio frequency (RF), and other electronic signals." (press release)(patent)
Think about it...
Do radio waves only travel through windows?
Does "reduced" signal leakage prevent interception?
"Tested and Proven" ???... Got proof?
What are the attenuation measurements?
Perhaps this would be effective if it were presented as part of a larger architectural shielding effort. In our opinion, the inventors worked hard and developed a clever and potentially useful product. But, to promote this film as a simple paste-on eavesdropping solution is neither credible, nor honest.
