With the popularization of wireless internet, the demand for wifi jammer in various conferences, exams, etc. has gradually increased, thus opening up a broad market for wifi signal jammers. However, there are still many users who do not know enough about wifi signal jammers, thinking that using high-power wifi signal jammers can achieve better results. In fact, this idea is wrong, and there are great security risks.
The working principle of the wifi jammer device is to use broadband to transmit interference signals to interfere with the uplink signal of the mobile phone, thereby shielding the work of the mobile phone. So, this is itself a signal transmitter. The signal transmitter produces radiation. According to the needs of users, the current shielding transmission power range is between 1W and 480W.
Choose the right wifi blocker
Generally speaking, for general exams and small meetings, using a wifi frequency jammer with a transmit power of 2W-10W can achieve good results. However, from the investigation of major schools and important conference venues, it is known that many venues only pursue high-power shielding. For example, there are more than 20 classrooms, and each classroom uses a shield, and chooses 30W to transmit power. After the inspection, because it is not used correctly, it often happens that the wifi bluetooth jammer is not closed in time, resulting in continuous transmission for several weeks.
Therefore, the unit applying the mobile phone shielding device should pay attention to the following three points:
1. Do not blindly apply high-power shields. The shielding effect can be achieved by applying 2W transmit power shielding in a classroom.
2. After use, it is necessary to turn off the wifi blocker in time to avoid continuous radiation.
3. Be sure to choose a wireless wifi jammer produced by a regular manufacturer.
