Bluetooth is a radio technology that supports short-range communication (typically within 10m) of the device. It can exchange wireless information between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. With "Bluetooth" technology, communication between mobile terminal devices can be effectively simplified, and communication between the device and the Internet can be successfully simplified, so that data transmission becomes more rapid and efficient.
In recent years, bluetooth technology has made a major breakthrough, but Bluetooth itself has great hidden dangers in terms of security. The first pairing of Bluetooth requires PIN verification. The PIN code only consists of numbers, typically 4 to 6 digits. After the PIN code is generated, the device automatically encrypts the PIN code using the E2 or E3 encryption algorithm that comes with Bluetooth, and then transmits the identity for authentication. In this process, hackers are likely to crack the PIN by intercepting the packet, disguising it as a target Bluetooth device, or using a "violent attack." At this point we need a Bluetooth jammers to prevent this from happening.
Electronic products such as smartphones around us all have Bluetooth capabilities, and many of us are used to "sharing" music and voice in public places without turning off Bluetooth devices. The portable WiFi signal jammer can disconnect unwanted Bluetooth signals and prevent unnecessary privacy leaks. Most Bluetooth interfering devices can not only interfere with WiFi 2.4GHz frequency, but also interfere with CDMA GSM 3G 4G mobile phone signals, and the design is small and portable, easy to carry, which is praised by many young fans.
The use of WiFi is becoming more and more common. It can help people share files and transfer documents. However, some hackers also use some illegal technology to steal other people's data and achieve their illegal legal interests. Once personal data is at risk, it will bring us significant losses, and even some more terrible things. The WiFi blocker is full-featured, small in size, and the price is only a few dozens of dollars. It is definitely a commendable product.
