- Currently, using a signal blocker for sale to block signals is a relatively effective method and will not damage electronic products. But how effective the shielding is depends on whether electronic products can still emit signals. How to test the effectiveness of the jammer? At this time, you only need to follow the following methods:
1. Test the shielding distance of the signal jammer. Don’t just try it with one or two network mobile phones and then be done. During the exam, cheating candidates use different mobile networks, especially 4G mobile networks. If the power is not enough, 4G may not be blocked.
2. Each mobile phone network must be able to meet the needs of small classrooms. To test the shielding effect after turning on the phone, there must be no signal on the phone within half an hour, and it cannot be intermittent.
3. If it is a signal jammer with a metal shell, touch the front and rear sides of the fuselage with your hands after turning it on for 1 hour. If the temperature is moderate and not hot, there is no problem. If it is very hot, it means it is not qualified. The continuous heating of the machine will cause the power of the jammer to attenuate. , unable to work stably, and prone to burns.
We need to test the effect of the signal jammer according to the above method and whether it can block various signals. Before use, you can use a variety of mobile phones to test and a variety of networks to test. Be careful to avoid interference when using it.
cell phone jammer
Signals can transmit information, but there are no signals in some special occasions, so using a signal jammer to shield signals in these special occasions is an ideal choice. It effectively identifies signals based on frequency and can be shielded. It can be said that its identification ability is very strong. Here is an introduction to how to use it:
1. Select the area where the mobile phone signal needs to be cut off, and place the signal jammer or cutter on the table or wall in this area.
2. After the installation is completed, turn on the power of the disconnector and turn on the power switch.
3. After the signal jammer for cell phone is connected, press the power switch cutter to start working. At this time, all powered mobile phones on site are in the search network state and lose the base station signal. Neither the calling party nor the called party can establish a call connection.
The signal jammer is indeed an ideal signal shielding instrument. With it, the signals generated by electronic equipment are automatically shielded. In order to achieve good use results, we must learn to master the correct use methods to achieve the effect of shielding signals. - İnsanlara gidiyor
