Electronic signals play a very important role in modern warfare. The stability of the signal is very important for combat. Therefore, while studying how to protect the stability of its own signals, the country will find ways to influence the signals of other countries. Yonhap News Agency said on Tuesday that according to a report from the South Korean government, North Korea has developed a powerful cell phone jammer that can shield GPS (Global Positioning System) satellite signals within a range of “over 100 kilometers.” The news agency said the news about the mobile phone jammer was included in a report submitted to the National Defense Committee of the South Korean Parliament this week.
