How to purchase mobile phone signal jammer equipment and matters needing attention
First, Cell phone signal jammers are selected by shopping around the three products, extensive research and understanding:
1. Research on product quality, technical means, and brand; 2. Through Internet search, preliminary understanding and communication with technical personnel, and listening to technical explanations.
Second, see the effect of the prison demonstration: select a few of the best ones, go to the scene to test and demonstrate the shielding effect.
3. The actual effect of the investigation case: 1. After the product is demonstrated, the application, operation status and actual effect of the product on other similar projects can be inspected; 2. It is better to bring the mobile phone into the shielded area after approval during the investigation. Perform the verification of the shielding effect.
4. Simple and quick method of judging the equipment: the equipment that can be considered 1. The area that should be shielded is not strictly shielded, which is costly and laborious and ineffective; 2. The area that should not be shielded has serious interference and is complained and cannot be used normally; 3. Too partial There is a gap between information detection and pseudo base station technology, ideals and reality, and there are currently no real successful cases in China to check.
Unsuitable equipment
1. Small size, the host and power supply are separated, and a circuit board is used inside; 2. An additional protective box is needed, which is small in size and light weight; 3. Natural heat dissipation area is small or a fan is used to help heat dissipation; 4. How much is inside the device The air circulates inside and outside, and the inside is easy to corrode.
Questions of life: Why is there no signal jammer on the plane?
Although the signal jammer is called a signal "jammer", it is essentially a signal "jammer" and a high-power jammer. The reason why mobile phones cannot be used on airplanes is to prevent mobile phone signals from interfering with airplane communications. Installing a "jammer" means installing a huge source of interference by yourself. Therefore, there will be no such device on the plane!
