In recent years, new forms of cheating in examinations have emerged constantly. The means and tools of cheating in examinations have become a professional and high-tech development trend, posing a serious threat to the normal order of examinations. The appearance of cell phone jammer can perfectly solve this problem.

The cell phone jammer is composed of several small power modules and related high power unit modules, field case and gain antenna, as well as scientific design, installation and debugging technology. It can cover a large area. Modular combination is characterized by simple operation, high reliability and easy upgrade. For on-site signal shielding, the internal modular combination of cell phone jammer has a high cost performance ratio, which can meet the customer's requirements to the greatest extent.

The production process strictly follows the ISO9001 quality system, adopts special structural design, and has uniform heat dissipation, earthquake resistance and moisture resistance. Therefore, it can effectively control internal and external interference, effectively ensure and improve the stability of performance. It can effectively and reasonably block different mobile phone signals in the shielding area without leakage. It will not cause signal interference to other electronic equipment.

The cell phone jammer has a network interface and supports networking. It can be used for separate shielding or networking shielding. The wireless signal shielding function can be realized by powering on and turning on the power switch. It can also realize functions such as automatic searching equipment, online equipment working status and remote control, free grouping control, etc. through the network.
