Mobile phone signal shield is a high-tech product that our factory adopts foreign advanced technology, aiming at the continuous development of communication system and elaborately developed according to the actual situation of foreign mobile communication. It can cut off GSM / CDMA / AMPS / DCS / PHS / 3G (WCDMA, TD-SCDMA and CDMA2000) and 4G mobile phone signals within a radius of 1-25m (about 10-250m2, and the shielding range can be adjusted according to the required place), and 2.4G wireless The signal makes the mobile phone unable to send and receive messages, but does not interfere with the work of other electronic devices, so as to ensure the safety of the required place. When the mobile phone leaves the partition range, it can resume normal use without any damage to the human body.
1. Effectively shield all communication signals such as CDMA (China Telecom), GSM (China Mobile, China Unicom), SCDMA (Netcom PHS), DCS (1800MHz), PCS (1900MHz), PHS (Telecom PHS), 3G mobile signal and 4G mobile signal,
2. Ultra thin shell, the surface can be pasted according to the needs of customers or silk screen logo (provide silk screen service)

Action radius beside the base station: 150-200m2. (the size of shielding area is adjustable)
Product size: 380x260x560 (mm) applicable power supply AC110V-240V 50 / 60Hz
Shielded band CDMA / TDMA: 870-880mhz GSM: 925-960mhz DCS: 1805-1920mhz; 3G: 2010-2025 3g1 2110-2145 MHz 4G: 2300-2483mhz: 2555-2655mhz
1. It can block all cell phone signals.
2. Only the downlink signal of mobile phone is shielded, and the base station is not interfered
3. Imported devices and slow start circuit design can avoid the phenomenon of ignition caused by mechanical switch, with high integration and stable operation.
4. Waterproof structure design of aluminum alloy outer box, indoor and outdoor installation and use.
5. One output port is designed, which is simpler and more convenient.
6. Reserved upgrade port.
7. Use an omni-directional antenna or directional antenna to transmit in the open space.
8. Indoor environment can adopt antenna distributed transmission, which is simpler.
9. It can be used in vehicle, and the installation is simple and convenient.
10. The external pulley is more convenient for installation and movement.
It is mainly used in prisons, detention centers, school dormitories, lawns, armed police internal security forces to deal with illegal gatherings, large-scale places, special operations for safety accidents, military field exercises, etc!
