With the development of the times, the mobile phone signal is getting stronger and stronger, and the mobile phone signal has also increased from the original 2g3g4g to 2g3g4g5g, and the frequency of the mobile phone signal is more and more. The role of the old interference equipment is becoming more and more limited. So we are constantly innovating. This product can support 10 different signal frequency bands, support simultaneous interference with mobile phone, wifi, GPS and other signals; and the single-channel power can be up to 5W, effectively expanding the operating distance.
