The gps jammer power of the signal masker is fixed, and the shielding radius of the unblocked space is determined by the path attenuation and the signal level of the receiving base station. To realize the interference of the mobile phone signal jammer to the mobile network, it is necessary to ensure that the signal field emitted by the jammer is stronger than the field strength of the mobile signal in the interference region. The closer the interference location is to the base station, the stronger the field strength and the smaller the effective interference region. The farther the interference location is from the base station, the weaker the field strength is, and the larger the effective interference area is.
 
Dudayev, head of the Russian Chechen insurgency group, was shot by a Russian army using a mobile phone. The phone may also leak during standby or even shutdown. Because the mobile phone must maintain an uninterrupted handshake with the communication network, the resulting electromagnetic spectrum can be easily identified, monitored and tracked.
