In order to make the mobile phone signal amplifier achieve the effect required by the user, some manufacturers arbitrarily increase the output power of the product, thereby causing direct noise interference and pilot pollution to the communication base station.
The noise coefficient, standing wave ratio coefficient, third-order intermodulation, frequency filtering and other parameters of these cell phone jammer often fail to meet the technical requirements stipulated by the state.
In addition, private cell phone signal amplifiers often do not have a good installation point, which usually coincides with the signal coverage point of the operator, causing the base station to not normally transmit signals to the area where the cell phone signal amplifier has been installed. Therefore, as long as there is a place where an inferior cell phone signal amplifier is installed, it will cause interference from a large number of base stations, causing the surrounding users to be unavailable.
It is illegal to install cell phone signal jammers without permission!
According to Article 70 of the "Regulations of the People's Republic of China on Radio Management", in violation of the provisions of these regulations, unauthorized use of radio frequencies, or unauthorized installation and use of radio stations (stations), the radio management agency shall order corrections and confiscate the illegal activities. Equipment and illegal gains from activities may be fined not more than 50,000 yuan; if they refuse to make corrections, they will be fined not less than 50,000 yuan but not more than 200,000 yuan.
The Criminal Law also stipulates that anyone who violates national regulations by setting up and using radio stations (stations) without authorization to interfere with the normal conduct of radio communications and causing serious consequences shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or surveillance, and a fine or a fine.
