In the third case, because of the special nature of the job or some other reasons, in short, you don’t want the car you drive to be continuously located and tracked by others, and you will also purchase Cell Phone Slot Machine Jammer to maintain your driving privacy. We have been focusing on the R&D and manufacturing of various test room signal jammers and GPS signal jammers for many years. Through an in-depth understanding of the principles of car locators, GPS jammers cut off GPS frequency band signals to make the car in a signal blocking state. Built-in antennas, external 2 antennas, 3 antennas, 6 antennas, 8 antennas, and many other products. Among them, the GPS jammer with 2 antennas is the most compact, which can effectively interfere with GPS and Beidou satellite signals, protect your privacy and information confidentiality, and will not affect mobile phone signals. cell phone jammer With advanced anti-interference ability, the mobile phone that is easy to install and use can run continuously for a long time. Choose the correct position of the protective cover carefully to prevent it from rotating.
The 5g era is coming, but sometimes these signals need to be blocked, such as the annual college entrance examination. For the college entrance examination in 2021, the shielded signal interval must contain 5g. Ok Cell Phone Slot Machine Jammer It can be done. We have professional personnel, factories, and researched new mobile phone jammers that can shield 5g signals. By generating a broadband comb-spectrum interference signal waveform in the baseband, the frequency or channel of the interfering target signal can be targeted and interfered, and all target signals can be continuously interfered for a full period of time. Compared with the noise interference and frequency sweep interference commonly used by existing domestic interference equipment, the outstanding advantages are:
