When many people buy phone jammers, they usually buy them at different prices. How to judge them? Is it worth that much?
Cell phone signal protectors have been used in many places, but they cannot be used immediately after installation. We also need to pass some tests to determine the effect of its use to make sure that it is truly effective. Below, as a manufacturer of mobile phone signal jammers, skylifr will teach you how to test the effect of cell phone signal jammers.
If you want to make sure that the cell phone jammer can effectively block the mobile phone signal is very important, then when buying a cell phone signal jammer, testing is a very important step.
The first is to test the coverage of mobile phone jammers. Don't just use one of the two Internet phones for a test drive. During the exam, the cheating candidates use different mobile networks, especially 4G mobile networks (4G networks use high-speed broadband transmission, if the mobile phone signal jammer function is insufficient, it may not be able to cover 4G).
What is the relationship between the power and the price of the jammer?
1. Depends on actual power? For each power source, the corresponding electronic components are different. Especially for some high power products, to achieve this effect, electronic components will be very expensive.
2. How many volts of power does it depend on? Just like, if you are a 1.0 displacement car, your horsepower is the same. If it is a 5v power supply, it is difficult to achieve 24w or 36w.
3. Take a look at the hull. It is a metal shell, a material shell or an aluminum alloy shell. Different shells and mussels have different prices.
4. In a little more detail, just look at the design of each module. Usually the manufacturer uses the same module, replaces the case and makes shield covers with different wattages.
