What is the type of wireless LAN signal jammer?
Canadian advertiser Grip Limited recently proposed a new idea. It's a tie that can hijack your home WiFi signal and change its transmission path. After wearing this tie, only users who are 10 feet away from the wearer can successfully find the WiFi signal. Therefore, when the father wears it, children who want to go online have no choice but to go around him. Therefore, from this conceptual point of view, this new technology is called TieFi (a combination of Tie tie and WiFi).
A few years ago, French researchers developed wallpapers that shield cell phone blocker and allow WiFi signals to be restricted to specific offices or departments. This will improve the security of WiFi. This shielding technology shields only wireless LAN signals of a specific frequency, not a general electrostatic shield, so mobile phones and radio broadcast signals can pass through. According to researchers, the price of this wallpaper is about the same as the price of a traditional midrange wallpaper and was launched in 2013. This wallpaper not only prevents snooping of WiFi signals, but can also be used in places where WiFi interference can occur. For example, you can use hospitals, hotels, theaters, etc. to prevent guests from trying to avoid payments using external free WiFi signals. Of course, consumers who are sensitive to electromagnetic waves are also potential marketing target groups.
