1. Product introduction:
ZJSC-PB08 can effectively shield all 2G/3G/4G/5G mobile phones, WIFI and other communication signals. The built-in omnidirectional antenna is used to transmit specific electromagnetic signals to form an electromagnetic protection field in the place where the use of wireless communication equipment is prohibited, so that the wireless communication equipment in the place and the external communication signal cannot be identified and connected, thereby cutting off the wireless communication tools in the place Contact with the outside world to eliminate hidden dangers of information security.

2. Use place:
School examination rooms, conference rooms, prisons, detention centers, hospitals, courts, interrogation rooms, confidential rooms and other places for information security and confidentiality.

3. Product features:
1. The latest multifunctional 5G model can shield all 2G/3G/4G/5G, 2.4G/WIFI Bluetooth and other signals.
2. The built-in space can be expanded to 18 modules, and different frequency bands can be increased and enhanced according to demand.
3. It adopts high-hardness PVC plastic shell, built-in aluminum heat dissipation strip and dual fans for ventilation and heat dissipation, excellent heat dissipation performance, sturdiness and durability, ensuring long-term uninterrupted and reliable operation.
4. High-quality built-in switching power supply, built-in antenna can effectively prevent the antenna from being damaged, and the effective shielding range is wider. It can be used with only one power cord, which is convenient and fast.
5. Original imported chip, stable frequency without frequency deviation.
6. It only shields the mobile phone signal and does not affect the normal operation of other electronic devices.
7. Ultra-low radiation, safety and environmental protection, no adverse effects on human health.
8. Only shielding the downlink frequency of the transmitting base station does not affect the uplink frequency.
