A mobile cell phone signal jammer, also called a mobile cell phone signal blocker, is a tool that allows nearby cell phones to be blocked from cell phone signals. Because of its function, it is destined that the mobile cell phone signal jammer is a double-edged sword. Today, I will share with you how to use the cell mobile phone signal jammer correctly.
Today, I mainly share the use of two types of cell phone signal jammers.
The first type of cell phone signal jammer is a hand-held cell phone signal jammer, which has the advantage of being a very convenient, portable cell phone signal jammer. You can take it with you to use in cafes, small meeting rooms and other scenarios. And it is a built-in battery, which can last up to 6-8 hours when fully charged. We can pay attention to the picture above. There are antennas on the mobile phone signal jammer. Different antennas represent different frequency bands. They are all marked, and the corresponding markings are installed. It can be simply understood as increasing the gain through the antenna, masking the signal emitted by the base station, so that the mobile phone only receives the signal of the shielding device, and the effect of shielding the mobile phone signal is achieved.
The second type of mobile phone signal jammer is a desktop mobile phone signal jammer. Even some mobile phone signal jammers that require high power and a wide range for outdoor use are basically desktop. The greater the power, the better the cooling function is required. The disadvantage compared to hand-held cell phone jammers is that they must be connected to AC power to use because there is no built-in battery. And the volume is also larger than the hand-held one, which is inconvenient to carry. The installation method is the same as that of the hand-held type, and it can be installed according to the frequency band of the antenna. There are two details to pay attention to. The first is that all antennas must be installed before turning on the power, otherwise the modules inside may be burned out. The second is that the device cannot be placed next to inflammable and explosive items. The surface temperature generated by the mobile phone signal jammer when it works can reach up to 50℃-60℃.
In addition, it is emphasized again that mobile phone signal jammers can only be used under the premise of reasonable and legal compliance. Water can carry a boat and capsize it. If there are children at home who like to play with mobile phones, you can try to use a mobile phone signal blocker to let the children put down their mobile phones to cultivate their other hobbies, or to complete their homework more efficiently. Many municipal projects also need to use mobile phone signal jammers, but I hope everyone can think a little more and think a little more for others. Do not interfere with the normal use of the phone by others.
