　　In addition to schools and examination rooms, the application of mobile phone signal jammers in some special places has also gradually become popular. For example, in some highly sensitive places such as government agencies, military bases, banks, etc., mobile phone signal jammers can prevent unauthorized communication activities and ensure information security.
