　　Working principle of mobile phone signal jammers

　　Mobile phone signal jammers interfere with the normal connection between mobile phones and communication base stations by emitting electromagnetic signals with the same frequency band as mobile phones, making it impossible for mobile phones to receive or send signals. Since terrorists often use mobile phones as remote-controlled detonation devices, mobile phone signal jammers can effectively prevent them from sending detonation signals, thereby thwarting potential terrorist attacks. In addition, this technology can also be used to protect the safety of important personnel, prevent information leakage, and ensure the safety of specific areas.

　　Typical Counter-Terrorism Case Analysis

　　1. Thwarting the assassination attempt on the President of Pakistan:

　　In December 2003, Pakistani President Pervez Musharraf was assassinated. According to reports, terrorists planned to assassinate President Musharraf by remotely controlling a bomb via a mobile phone. However, the mobile phone signal jammers installed along the presidential motorcade successfully blocked the terrorists' detonation signals and thwarted the plot. This incident further proves the importance of mobile phone signal jammers in counter-terrorism operations.

　　2. Protection measures during President Bush's visit in London:

　　In November 2004, then-U.S. President George W. Bush visited London, England. In order to ensure the safety of the president, the British police reportedly considered deploying mobile phone signal jammers along the presidential motorcade to prevent terrorists from using mobile phones to detonate bombs. Although this measure was not made public in the final implementation, it shows the potential of mobile phone signal jammers in the protection of VIPs.
