No matter where we go now, it looks like the first sentence we enter the store is to ask the owner, "What's your WiFi password?"
It is undeniable that the wireless network has permeated all aspects of our lives. If we ever lose it, the consequences will be unimaginable. But did you know that WiFi jammer detectors are actually weird?
Recently, Hui Guoren found a wifi jammer, which can block surrounding wireless networks and prevent you from surfing the internet. The success rate can be as high as 99%, which is really scary.
This motherboard is the NodeMCU ESP8266 which is very popular recently in the open source community. It was originally a device that provided transparent transmission from the WiFi serial port as a micro-controller. It was actually a 32-bit Tensilica Xtensa LX106 processor with an 80 MHz clock frequency and a full wireless WiFi stack. Developers are transforming it to simplify network shielding. In the video you can see the invisible. So I can only say, see it, stay away.
A few days ago, Canadian advertiser Grip Limited came up with a new idea - a tie that can hijack your home's WiFi signal and change its transmission path. After wearing this tie, only users within 3 meters of the wearer can successfully search for WiFi signals. Therefore, when dads wear it, kids who want to go online have no choice but to shop around for their dad. So in terms of this concept, we call this new technology TieFi (a combination of Tie tie and WiFi).
Even with such a magical connection, I think maybe not everyone understands the heart of the matter yet, ”a family doctor said in a media interview.
A few years ago, French researchers developed a wallpaper that can protect WiFi signals so that WiFi signals can be confined to specific offices or departments, thus providing better WiFi security. This shielding technology is not common electrostatic shielding, but only protects wireless LAN signals of a specific frequency, so that mobile phones and radio broadcast signals can pass. According to researchers, the price of this wallpaper is almost the same as traditional mid-range wallpaper, and it went on sale in 2013.
Besides preventing spy on the WiFi signal, this wallpaper can also be used in the places where WiFi interference may occur. For example, hospitals, hotels, theaters, etc. can also be used to prevent customers from trying to use free external WiFi signals to avoid paying. Of course, consumers who are more sensitive to electromagnetic waves are also a potential marketing target group.
Originally, there are wifi jammer detectors like pepper bottles, but they are basically not used in China, so we list the most common. Do you want to buy?
