Utilizing Jammers to Inhibit Micro Devices from Capturing Audio
Signal jammers, such as those for cell phones, Wi-Fi, and Bluetooth, are often distinct devices. They can be portable or remotely activated in an office context, functioning on the network frequencies of GSM, CDMA, Wi-Fi, or Bluetooth. Once the jammer is turned on, the mobile phone or other devices will indicate "No signal," "Please select a network operator," and "No network found," among other messages. This indicates that communication within the interference zone is no longer feasible. The interference signal from the jammer also disrupts other wireless data transmissions. Therefore, mobile phones and similar devices cannot function as eavesdropping tools. When a GSM signal jammer is in use, the mobile device is incapable of receiving any external signals. Moreover, cell phone and wifi jammers do not generate strong radio signals or full-frequency noise, ensuring that they do not interfere with the operation of other household devices and are safe fo...
