Should jammers be used in public?

The wifi jammer will send a predefined white noise signal within a specific bandwidth, thereby interrupting all wifi / Bluetooth communication. Our scrambling unit can be programmed to scramble any number of discrete frequencies within its RF functional range. For a basic wifi interference system, the effective interference radius is about 20 meters.

Jammers also include Wi-Fi jammers and cell phone jammers, which can prevent your phone from receiving or making calls, emails, and text messages. They can also prevent Wi-Fi-enabled devices from connecting to the Internet for multiple operations, prevent you from using GPS to receive accurate positioning signals, and prevent being discovered by first responders in an emergency.

The progress of electronic warfare is one of the key factors guiding the development of armed autonomous systems. At present, drone aircraft are launching electronic warfare with cellular communications, but it is not difficult to imagine that the same theory applies to new technologies. In this case, it is easy to imagine that other vehicles will become jamming devices in the future battlefield or even in the current battlefield.

Identity verification attacks or more generally “interference” attacks may violate the laws or regulations of certain countries. However, it is often difficult to determine the source of interference because it is small and easy to hide. Wammer is an acronym for wifi jammer and combines all the steps behind an extremely simple but effective user interface. To launch an attack, the user simply presses the “Activate Jammer” button. That’s it! A few seconds after the interference starts, the user ’s device will be the only one connected to the WiFi access point.

The questions are: (a) Today, good Wi-Fi routers use 5 GHz in addition to 2.4 GHz, and there are more 5 GHz channels available. Then there is (b), if you block the 2.4 GHz channel, the owner of the access point is enough to change the channel. When they change the channel, and you change the channel on your phone, this may become an escalating war. Constantly. Until someone climbs with a baseball bat or something more serious.

As we said, we are very dependent on wireless networks. Wireless communication is like two people talking. One of them speaks and listens, and vice versa. What happens if the third person approaches them and starts shouting so loudly that the other two can no longer listen to each other? First, they will try to continue the conversation, but soon they will realize that this is impossible, and they will stop talking while waiting for the lunatic to remain silent. This is what happens with many communication protocols. When they found that the chain was already occupied, they withdrew. Therefore, the exchange of messages between these devices is suspended. Even if they try to communicate without support for free, just like other protocols, if the noise is too loud, the other side will not be able to receive the message correctly and will not be able to communicate. This is what we call wireless interference.
