Wi-Fi most commonly uses the 2.4 gigahertz (12 cm) UHF and 5.8 gigahertz (5 cm) SHF ISM radio bands. Anyone within range with a wireless modem can attempt to access the network; because of this, Wi-Fi is more vulnerable to attack (called eavesdropping) than wired networks. Wi-Fi Protected Access is a family of technologies created to protect information moving across Wi-Fi networks and includes solutions for personal and enterprise networks. Security features of Wi-Fi blocker constantly evolve to include stronger protections and new security practices as the security landscape changes.

The main issue with wireless network security is its simplified access to the network compared to traditional wired networks such as Ethernet. With wired networking, one must either gain access to a building (physically connecting into the internal network), or break through an external firewall. To enable Wi-Fi, one merely needs to be within the range of the Wi-Fi network. Most business networks protect sensitive data and systems by attempting to disallow external access. Enabling wireless connectivity reduces security if the network uses inadequate or no encryption.

Therefore, in response to this situation, scientific researchers have developed a WIFI jammer device. By using this device, you can create a 5-40m signal vacuum around the area, isolating all wireless network signals. Isolating WIFI signals not only protects your network, but also protects your health. Studies have shown that people exposed to wi-fi radiation for long periods of time are more likely to develop cancer

The recent explosion of free, public Wi-Fi has been an enormous boon for working professionals. Since these free access points are available at restaurants, hotels, airports, bookstores, and even random retail outlets, you are rarely more than a short trip away from access to your network, and your work. This freedom comes at a price, though, and few truly understand the public Wi-Fi risks associated with these connections. Learning how to protect yourself will ensure your important business data remains safe.

First, try not to connect to public WIFI. If your smart device is connected automatically, try using a WIFI jamming device and refuse to receive WIFI signals.
Second, if you have to use this kind of WIFI, be careful not to open your social software and bank accounts.
Thirdly, please confirm whether WFI is safe before using WIFI, and try to avoid the connection of unsafe WIFI.
