This high-end mobile phone signal shielding device is a product developed by our company's specialized school. It has the following characteristics in view of the specific use of the school:
1. The built-in antenna design avoids the trouble of screwing the antenna and also eliminates the possibility of students destroying the antenna;
2. Six--eight-channel design The shielding range is more precise and the anti-interference ability is stronger:
The high-end mobile phone signal shielding device adopts 6-8 channel design, which completely solves the problem that the 3, 4, and 5 mobile phone shields are shielded from 3G signal instability and the shielding distance is too close, sometimes there is no phenomenon, completely shielding the mobile phone short message. Even if it is close to the mobile phone transmitting base station, it can guarantee to shield one classroom. If it is far away from the mobile phone signal transmitting base station, it can be used in multiple classrooms.
Due to the multi-channel design, it will inevitably increase the cost of the product, but his shielding effect is unmatched by the ordinary mobile phone signal shielding device. This product is mainly used by some high-end users. It is targeted to shield all current domestic The mobile phone signal, including the 3G and 4G frequency bands of mobile, China Unicom and Telecom launched in the past two years, adopts the segmentation shielding mode, which only interferes with the downlink signal, and does not affect the uplink signal of the mobile operator. The green environment has no pollution to the electromagnetic environment.
In addition: This high-end mobile phone signal shielding device is completely modular design, users can add GPS shielding module, WIFI shielding module, wimax shielding module, etc. as needed


3. The company's corresponding national green environmental protection requirements use injection molding once to form a shell to solve the problem of hot metal casing body, the body is light and easy to carry, and is also convenient for secondary recycling.
4. The dual-channel fan design ensures good heat dissipation and prolongs the service life. Due to the built-in power amplifier chip, there is a certain amount of heat during the work. The product has a heat sink and a dual-channel cooling fan to prevent the temperature from burning up and killing the chip. Time-stable work greatly extends the service life of the product, and the average failure rate of the product is 150,000 hours.
5. Built-in dual-channel metal industrial switching power supply is stable
The power supply is the heart of electronic products. The most important thing is the quality of the power supply. The built-in dual-channel metal industrial switching power supply is designed for the shield and has sufficient bandwidth and power for each channel.
