Chinese laws related to cellphone wifi signal jammer devices
According to the "Radio Management Regulations of the People's Republic of China" implemented on December 1, 2016, anyone who uses cellphone signal jammer devices without permission or sets up or uses radio stations without permission shall be ordered by the radio management agency to correct the situation, confiscate the equipment and illegal gains used in illegal activities, and may be fined up to 50,000 yuan; if the person refuses to correct the situation, he shall be fined between 50,000 yuan and 200,000 yuan; if the person sets up or uses radio stations without permission to engage in illegal activities such as fraud, and does not constitute a crime, he shall be fined between 200,000 yuan and 500,000 yuan.
The lawyer said that no unit or individual may use jammer blocker device without permission, and may not cause harmful interference to radio services carried out in accordance with the law; if necessary, they should go to the local radio management department for approval and filing. The management of mobile phone signal blocking is very strict, such as the use of government agencies, school examinations, etc., which also needs to be approved, and must be used within a controllable range and within a specified time, and must not affect the normal communication industry.
