Use signal jammers with caution from mobilejammer's blog

Jammers are a signal blocking device which transmits synchronized radio waves at the same frequency as a device like a cell phone or drone in order to blur its signal.

These are favored by companies who deal with sensitive information to prevent leaks. The 5GHz WiFi jammer is effective up to 40 meters and will block WiFi and phone signal in a fixed space.

For something more mobile, the WiFi Mini Signal Blocker is small and much cheaper than the 5GHz. Designed to be carried around in your pocket, this WiFi jammer provides 10 meters of protection no matter where you are.

This jammer is effective if you are working with sensitive data away from work or your home, like a hotel or some other more public space. With up to two hours of battery life on full charge, it’s also ideal for people who feel more comfortable with a bit of a barrier between themselves and other people’s devices.

The next threat you should know about is related to the wireless internet usage. Both WiFi and Bluetooth are poorly protected against hackers thus your personal data is in potential danger all the time if there is a wireless access to the internet nearby. Not only information about you can be stolen, there are far worse things might happen: law enforcement agencies can connect to your webcam and watch everything through it, or they can simply use hidden cameras and microphones, installed in your house, for eavesdropping and snooping on you secretly, getting back streaming data with the help of WiFi and Bluetooth connections.In this case you will need a powerful wireless signal jammer, bluetooth jammer or WIFI blocker. All these devices work on 2.4 GHz frequency so actually you will only need one device - 2.4 GHz wireless jammer.

Terminology confuses us all at some point. [A good explanation of the difference between the WiFi jammer and the deauthenticator in the video embedded below. Many of you already know the difference, but it is useful to point out the difference, because many people refer to de-authentication devices as "WiFi jammers."

They continue to explain in the YouTube video that the jammer will basically release a lot of noise on all WiFi channels, making the frequency unusable within a given distance from the jammer. Jammers are also usually expensive and mostly illegal, so unless you build them yourself, they are difficult to find.

On the other hand, WiFi de-authentication works very differently. WiFi sends unencrypted data packets, called management frames. Because these are unencrypted, even if the network uses WPA2, malicious parties can send de-authentication commands that will direct users out of the access point. 802.11w can encrypt management frames. It has been around for a while, but the manufacturer seems to ignore it and has not implemented it, even if it can improve the security of WiFi devices in such attacks.
