What are Wi-Fi jammers and how do they work?
Wi-Fi jammers are devices that intentionally disrupt or block wireless communication signals, including Wi-Fi, Bluetooth, and cellular networks. They work by transmitting a signal on the same frequency as the targeted network, overpowering the original signal and preventing devices from connecting or communicating effectively. This can be done using a variety of methods, including brute force signal jamming or more sophisticated techniques that mimic the characteristics of the targeted network.
Wi-Fi jammers can be used for a range of purposes, from legitimate applications such as military communications and security testing, to malicious activities like disrupting critical infrastructure or facilitating criminal activity. The use of Wi-Fi jammers is regulated in many countries, and their sale and possession may be subject to laws and restrictions. However, this has not prevented the proliferation of these devices, which can be easily purchased online or built using readily available components.
Do criminals really use Wi-Fi jammers, and if so, why?
Yes, criminals do use Wi-Fi jammers, and they can be a useful tool in a range of illicit activities.
