In Japan, some criminals will use their mobile phones to withdraw money through ATMs after they have obtained other people's mobile phone numbers, falsely claiming that their family members need to remit medical expenses for fraud. Therefore, Chiba Bank of Japan installed mobile phone jammers next to ATMs to prevent fraud. In the United States, cell phone jammer are generally used in prisons. At one time, this equipment was also purchased and used by some coffee shop and barber shop operators, restaurant owners, theater operators, etc., but later private blocking of signals was banned by legislation, and offenders would be fined up to $11,000. fine.
"Obviously, the random use of this mobile phone jammer device interferes with citizens' freedom of communication." Dong Zhengwei, a lawyer at the Beijing Bank of China Law Firm, said that on some specific occasions, participants need to be shut down or turned into a silent state, which also requires the consent of the other party , If there is a consensus, there is no problem. However, if such shielding equipment is installed, the forcible prohibition of mobile communications can be considered "unconstitutional."
According to my country’s Constitution, citizens’ freedom of communication and confidentiality are protected by law. Except for the needs of national security or the pursuit of criminal offenses, the public security organs or procuratorial organs shall inspect communications in accordance with legal procedures, no organization or individual shall infringe citizens’ freedom of communication and confidentiality for any reason.
Dong Zhengwei told the Beijing Science and Technology News that only some units involved in state secrets can use mobile phone jammers with the approval of relevant departments when conducting confidential meetings. In June 2001, the then Ministry of Information Industry issued the "Notice on Prohibiting the Illegal Development, Production and Use of Radio Interference Equipment", which clearly emphasized that "blocking mobile phones to dial in and out within a certain range, this kind of equipment in the society The use disrupts the order of radio waves and severely violates the legal freedom of communication of mobile phone users, and must be stopped in accordance with the law."
"But the current situation is: there is no legal prohibition on the sale of this kind of mobile phone jammer electronic equipment, but only restricts the illegal use. Some theaters and libraries are also using this equipment, and in many cases it has not been approved by relevant departments. It is more difficult to supervise.” Wang Lijun believes that to fundamentally eradicate the use of such equipment, relevant national departments must ban it through clear laws and regulations, or formulate “approval by the local radio management department before it can be sold. Or use regulations like "to control market disorder."
