you can buy some radar detector and laser jammer

Even if the relevant laws and regulations have been promulgated, due to insufficient penalties, many people still take the risk and install cell phone signal jammers privately. Among them, quite a few people do not understand the working principle of mobile phone signal jammers, mistakenly think that cell phone jammer are almost the same, and just choose manufacturers with incomplete qualifications, or buy cheap ones.And this requires a considerable risk. Mainly reflect radiation, interference to base stations, etc.Therefore, inferior mobile phone signal jammers are not required.Inferior mobile phone signal jammers just blindly increase the shielding power.

Most of the Radar Detector And Laser Jammer on the market use the same frequency suppression method for signal shielding, which will inevitably generate radiation. Inferior mobile phone signal jammers cut corners, and have not tested and limited the radiation value. If the radiation value is too high, it will cause damage to human health. In addition to increased radiation, they also have no corresponding TD synchronization function, which will cause mobile phone signal jammers to cause interference to communication base stations. At that time, mobile operators will report complaints to the local radio administration, because they have violated the radio management regulations and are bound to be punished accordingly.

Laptops are used by more and more people for office and even entertainment purposes due to their convenient portability and other advantages.
