Wifi jammers are usually used in exam rooms, supervision places, secret conference rooms, etc. When using the isolator in these places, it is necessary to ensure that the shielding effect of the wireless wifi signal jammer achieves the expected effect. In fact, there are many factors that affect the shielding effect of the wifi jammer, such as the distance between the installation site of the wifi jammer and the nearby signal base station, the transmit power of the jammer, and the use of it through the wall. To ensure whether the wifi blocker can effectively block the wifi network signal, testing is a very important step when purchasing a blocker.
First of all, test the shielding distance of the wifi blocker, don't use only one or two network types of mobile phones. The mobile phone networks used by candidates who cheat during the exam are different, especially the 5G mobile phone network that has been very popular in the past two years. Therefore, it is necessary to test the mobile phones of all the networks of the current communication providers. Make sure that the wifi blocker can block all mobile phone networks within the range of an exam room, so that you are qualified!
Then test the stability of the shielding effect of the wifi jammer device. After powering on, test the shielding effect to ensure that the mobile phone has no signal, and the mobile phone signal cannot appear from time to time. Otherwise, someone will use this intermittent time to send test information. This time is enough for candidates to pass the answer to cheat. Therefore, when purchasing a wifi frequency jammer, you must pay attention to the on-site detection of the shielding effect of different mobile phones to ensure that the jammer can truly achieve an effective shielding effect.
How to use a wifi blocker
How to use the wifi signal jammer: The mobile phone signals in the school classroom are transmitted to the classroom by the remote base station signal through the doors and windows, so the most reasonable installation position is to select the installation position of the wireless wifi signal jammer in the examination room. The middle of the wall is on the side of the base station so that the shielding effect of the shielding device can be maximized. Then determine the area where the cell phone signal will be blocked, and place the blocker on the desktop or wall in this area. After the installation is complete, continue to turn on the power supply of the shield and turn on the power switch.
After the wireless signal jammer device is connected, it can work directly by pressing the power switch. At this time, all the mobile phones used on the scene will lose the base station signal and can no longer make calls.
Over the years, we have produced various types of wireless wifi bluetooth jammer to escort the college entrance examination room, and spare no effort to create a fair examination environment for candidates
