The heat dissipation problem has always been the shortcoming of mobile phone jammers. Compared with the mobile cell phone signal jammer produced by other companies, the upgraded version of MDPB-5E (6 channels) continues all the advantages of MDPB-5E, metal body and increased heat sink , Both ensure the heat dissipation performance of the machine, so that the machine will not cause the problem of unstable shielding effect due to the overheating of the body during the working process. But in terms of volume, the upgraded version of MDPB-5E (6 channels) is small and light, easy to install, plug and play, and will not cause any problems on the floor. The five antennas above the machine ensure the sensitivity to the signal, expand the shielding effect of the mobile phone jammer, and improve its own work efficiency. At the same time, users can choose whether to extend the antenna according to their own situation to expand a larger shielding space.
Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station, achieving the purpose of shielding the mobile phone signal. No service system and other phenomena.
Mobile phone signal jammers are mainly used in examination rooms, prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, libraries, school dormitories, and special safety And confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile politicians and business dignitaries guarding) scenes, etc., and the status of mobile phone signal jammers in social life is becoming more and more important.
