WLAN jammers emit noise signals that interfere with WLAN / Bluetooth communications within a certain bandwidth. Our interference unit can be programmed to interfere with any number of discrete frequencies within its radio frequency operating range. For a simple WLAN interference system, the effective interference radius is approximately 20 meters.
Jammers also include wifi jammer and cell phone jammers, which can prevent your phone from receiving or making calls, emails, and text messages. You can also prevent Wi-Fi enabled devices from performing multiple actions to connect to the Internet, prevent you from using GPS to get accurate location signals, and prevent emergency responders from finding you in an emergency.
The development of electronic warfare is one of the key elements in the development of military autonomous systems. Drones are now waging electronic warfare against cellular communications, but it's not hard to imagine new technologies will apply the same doctrine. In this case, it is easy to imagine that other vehicles will become disruptors on the battlefield in the future or even now.
Removing authentication attacks or general "tampering" may violate the laws or regulations of some countries. However, because the source of interference is small and easy to hide, it is often difficult to identify the source of interference.
The problem is as follows: (a) Good wireless routers now use 5 GHz in addition to 2.4 GHz, and additional 5 GHz channels are available. Then (b) if you block the 2.4Ghz channels, all the owners of the access point only have to swap channels. If they change the channel and channel on their phones, it can turn into an escalation of war. Unending. Until someone has a baseball bat or worse a gun.
As I said, we rely heavily on wireless networks. Wireless communication is like two people talking. One of them speaks first and then listens, and vice versa. What if a third person walks up to you and starts screaming so the other two can't get along? At first they will try to keep the conversation going, but soon they will realize that it is impossible. They will stop talking and wait for the fool to shut up. This is the case with many communication protocols. If you find the channel is busy, please disconnect. As a result, the exchange of messages between these devices has been interrupted. Even if they try to communicate when the media is not available, just like other protocols, when the noise is too high, the other party does not receive the message properly and cannot communicate. We call this wireless interference.
