WiFi and bluetooth are the most widely used wireless technologies, using a 2.4ghz band to exchange data over short distances between fixed and mobile devices. From this point of view, wi-fi or bluetooth requires people to use them to send messages and documents to create great convenience. Transmission in the LAN is faster and does not require data traffic to complete the data transfer. As a result, wi-fi connections from large companies are cheap because they can connect to multiple systems on wifi signals. Bluetooth can also be used to help people send and share files. With the development of wireless network, now, people can easily access WiFi network, bringing a lot of convenience to people.

Even though they bring a lot of convenience to people's life and work, bluetooth and WiFi have many disadvantages, among which the most prominent one is security. For example, all personal data stored on a laptop or PDA can be exposed to everyone in the same area. If improperly configured, criminals can easily obtain passwords and important personal information from wireless networks. Once someone else knows the password, it's a real risk. The most obvious aspect is that your privacy is likely to be compromised by hackers, whose passwords are used as wireless networks because of their poor capabilities. On the other hand, because WiFi and bluetooth must follow your location and working ability, it is similar to the location of a triangle cell tower. So, how to make sure your information is not disclosed.WiFi Jammer are an essential tool in the face of the threats that can be posed by wifi and bluetooth.

When you exchange data over wifi or bluetooth, our secret data will be hacked. This is because the wireless Internet is poor at fighting hackers. Another danger comes from the danger that WiFi and bluetooth need to share our location while working, and that hackers will use to do something dangerous for us. Everyone will know our location through the wifi service, how dangerous it is, so. To protect ourselves from potential danger, we need Wifi jamming scramblers. It is known as wireless networking jamming killer.
