In order to ensure the fairness and impartiality of the examination and prevent cheating using mobile phones, a wireless signal shielding system will be installed in the examination area for signal shielding during the college entrance examination. Although this will bring some inconvenience to the lives of the surrounding people while ensuring a fair examination, after all, the college entrance examination is an important way for the country to select talents, and it is only once a year, so this unconventional method is adopted.
There are many occasions where the wireless signal shielding system is used in the examination room. With it, it is difficult for mobile phones to transmit signals, which can prevent candidates from secretly using mobile phones to send messages. However, before using the wireless wifi signal jammer, we should also pay attention to some uses Misunderstanding:
①In different places of use, the wireless wifi bluetooth jammer will have different effective shielding ranges. This is closely related to the signal field strength on site. Different models of mobile phones may not have the same shielding range at the same location, so they should be selected according to the actual situation before use.
② Factors that affect the shielding range of the wireless wifi frequency jammer include but are not limited to the distance from the base station, the wall material of the site building, the installation height, and the installation specifications.
③ During use, in order to avoid possible interference to some electronic devices, keep a distance of 1 to 2 meters from commonly used devices.
The wireless wifi jammer device can effectively shield the signal and prevent the transmission of the signal. When we use the wireless wifi disruptor, we should know some misunderstandings, so that we can completely shield the signal in the maximum range.
