Cell phone signal jammers have become a must-have artifact for special occasions. In order to prevent information security leaks, many companies and units have installed such devices to prevent such situations from happening. However, some units are not sure how to choose a mobile phone signal jammer.
Mobile phone signal jammers are designed to effectively avoid and affect relevant data signals on mobile phones, such as GPS, WIFI, 2G, 3G, 4G, or 5G in the future. Mainly using on-campus examination rooms, cells, detention centers, etc., to ensure fair and reasonable testing, junior high school to high school, college entrance examination, or ordinary examination simulation. So how should you choose a mobile phone signal jammer for sale? Today I will teach you how to choose in four parts.
1. Shop around to select products, and conduct extensive research to learn more about:
1. Conduct investigations on product quality, methods and well-known brands;
2. Through website search, basic understanding and communication with professional and technical personnel to obtain technical interpretation;
2. Examine the actual effects of examples:
1. After passing the demonstrated product, you can observe the application, management status and actual effect of the product on other similar projects;
2. During the inspection, it is best to take the mobile phone to the shielding area after approval to verify the shielding effect.
3. Cell demonstration to see the actual effect:
We will select a few candidates on a merit-based basis and go to the site for on-site inspection and evaluation to demonstrate the actual results;
4. Easy and quick identification of equipment methods:
Consider the equipment you choose
1. The areas that should be shielded are not strictly shielded, and it is ineffective to waste money and effort;
2. Areas that should not be blocked have serious impacts, are reported, and cannot be used normally;
3. There are differences between the technology, ideals and reality of excessive bias detection and pseudo base station. At present, there are no truly successful examples in China;
Equipment not suitable for use
1. Small size, the server and switching power supply are separated, and a PCB circuit board is used on them;
2. A separate safety box must be installed, which is small in size and light in weight;
3. Of course, the total heat dissipation area is small, or you can choose wind-assisted heat dissipation;
4. There are several places in the equipment where gas flows inside and outside, and the internal structure is easily corroded;
