Shop around to select products and conduct extensive research to learn more about:
1. Investigate product quality, technical means, brand, etc.;
2. Through Internet search, initially understand and communicate with technical personnel, and listen to technical instructions;
Prison demonstration to see the effect:
Select a few and go to the site to test and demonstrate the shielding effect;
The third part examines the actual effects of the case.

Equipment not suitable for use
Small in size, the host and power supply are separated, and a circuit board is used internally;
An additional protective box is required, the cell phone jammer which is small in size and light in weight;
The natural heat dissipation area is small or a fan is used to assist heat dissipation;
There are multiple internal and external airflows circulating inside the equipment, and the interior is prone to corrosion;
