Take a look around, choose suitable portable jammer from three companies and learn more about them through extensive research:
1. Carry out research on product quality, technical means and brand;
2. Get a preliminary understanding by browsing the network, communicating with technical staff, and listening to technical explanations.

Second, see the effects of the prison demonstration:
Pick some of the best, visit the website to study and demonstrate the shielding effect.

The real impact of the case study:
1. After demonstrating high power jammer the product, you can investigate the application, operational status, and actual impact of the product on other similar projects.
2. It is better to bring the mobile phone to the shielded area after the approval during the inspection to check the shielding effect.

Simple and quick method for evaluating devices:
Equipment that can be considered
1. The area to be shielded is not strictly shielded, which is expensive and troublesome and has no real effect.
2. The area that should not be shielded is severely disturbed, weighed down and cannot be used normally.
3. There is a gap between overly biased detection and pseudo base station technology, ideals and reality, and there are currently no really successful cases in China.

Inappropriate equipment
1. The main unit and drone jammer power supply are small and separate. A printed circuit board is used inside.
2. It must be equipped with a small and light protective box.
3. The natural heat dissipation area is small or fans are used to help dissipate heat.
4. There are many places where the air circulates inside and out and the inside easily corrodes.
