Wi-Fi signal shielding equipment is used in many places, but it is not immediately available after installation. We also need to go through a certain test to determine its use effect and ensure that it is truly effective. Next, we will share with you how to test the effect of wifi jammer.
To test the shielding distance of the wifi signal jammer
Don't just use one or two network mobile phones to try it out. Cheating candidates use different mobile phone networks during the exam, especially 4G mobile phone networks. 4G networks use broadband high-speed transmission methods. If the power of the wifi frequency jammer is not enough, it may not block 4G. Therefore, it is necessary to find all network mobile phones of the current mobile communication providers before testing, to ensure that each mobile phone network can meet the minimum one classroom, and then test the shielding effect. Sometimes not.
To test the temperature of the wifi blocker
If the wifi jammer kit with the metal shell is turned on for 1 hour, touch the front and back sides of the fuselage with your hands. If the temperature is moderate and not hot to the hand, there is no problem. If it is very hot, the quality is not good. Because the machine continues to heat up, the power of the wifi isolator will be attenuated. It can not work stably and is prone to burns.
