Cell phone jammer is a common jammer that can effectively block the transmission of mobile phone signals. In private places, many people use mobile phone signal jammers to prevent others from monitoring or recording through their mobile phones. The working principle of a mobile phone signal jammer is to divert or block mobile phone signals by sending interference signals, thereby achieving the effect of blocking mobile phone signals. This type of jammer is widely used in highly confidential places such as government agencies and police stations to protect the security of confidential information.
