Sharing of selection methods and precautions for mobile phone signal jammers from YIFALIU's blog

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.

After the demonstration, the application, operating status and actual effect of the product in other similar projects can be tested;

During the inspection, take your mobile phone to an approved shielding area to verify the shielding effect.

Simple and quick way to judge the signal blocker:

What devices to consider

The area to be shielded is not strict enough and the effort is not effective enough;

Areas that cannot be shielded have serious interference, complaints, and cannot be used normally;

There is a certain gap between biased signal detection and pseudo base station technology, and there is a gap between ideal and reality. Currently, there is no truly successful case in China;

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;
