Recently, we can see that a kind of machine has been installed in the examination room. This is the wireless wifi signal jammer that has been vigorously promoted by many schools recently. It is a problem that can effectively counteract electronic signal cheating. Although it has obvious effects, but What is not known is that when it is actually put into use, the shielding effect will be different due to the installation location and site conditions, mainly these places will affect the effect of the wireless wifi jammer device.
Although the size of the shielding range we see can be clearly seen in the description of the wireless signal shielding device, these data are divided into different situations in practical applications. First of all, the distance from the base station is one of the reasons that affect the shielding range. The impact is different according to the distance from the base station. Secondly, the wireless wifi bluetooth jammer cannot pass through the wall, which will greatly reduce its shielding effect. In addition, metal objects will also directly affect the shielding effect. Therefore, the shielding range of the wireless signal shielding device not only depends on the transmission power of each module of the wireless wifi frequency jammer, but also has a great relationship with the signal field strength of the site base station and the material of the obstacles. Although there are several problems that will affect the effect of the wireless signal jammer, it is still the most effective way to eliminate electronic cheating.
