If you think your neighbor has a cell phone jammer in his or her basement, then you are not alone. You can use the application to check if the signal bar on your phone is still working. If your signal bar disappears, you will be able to locate the jammer and how to restore it. But remember, not all jammer devices are suitable for all network modes.
Signal jammers can interfere with radar systems, especially those operating in the frequency range of interfering signals. By transmitting interference signals, the radar system can be prevented from working properly or misreporting, thereby interfering with radar detection and monitoring. However, using signal jammers to interfere with radar systems is illegal and may pose a threat to national and public security.
The signal jammer works by broadcasting a radio frequency that is the same as the radio frequency used by mobile phones. They will prevent communication between mobile devices and base stations. However, this does not mean that they are illegal. These devices can only be used to limit the number of mobile phone users, but they are not discounted. Therefore, you should know how to detect the phone jammer before it starts causing damage.
Signal jammers can interfere with onboard navigation systems, especially those operating in the frequency range of interfering signals. By transmitting interference signals, the onboard navigation system can be prevented from working properly or misreporting, thereby interfering with the navigation and driving of the vehicle. However, when using signal jammers to interfere with the vehicle navigation system, it is necessary to be careful not to cause danger to other vehicles and pedestrians.
Another method to detect mobile phone jammers is to check the strength of the signal. The output signal of the jammer may be much higher than the signal of the nearest mobile phone base station, which means that the phone cannot receive the signal at all. This makes it difficult to make phone calls. You can also check if your phone is damaged. The frequency used by the phone is similar to that of the jammer, but the sound is louder.
