With the popularity of mobile phones, the demand for wireless jammers in conference rooms, school examination rooms, etc. has gradually increased, thus opening up a broad market for wifi signal jammer. However, there are still many users who do not know enough about wireless jammers and think that only using a high-power wireless jammer can get a good shielding effect. In fact, this idea is wrong, and there are great potential security risks.
The working principle of the wireless jammer is to interfere with the mobile phone signal by transmitting the interference signal, so as to realize the shielding of the mobile phone. So, it is a signal transmitter in itself.
Generally speaking, for school examination rooms and small conference rooms, a wireless jammer with a transmit power of 2W-10W can achieve good results. However, according to surveys of major schools and major conference venues, many venues only pursue high-power shielding. For example, there are more than 20 classrooms in a school, and each classroom should be installed with a jammer, but some users only choose high-power transmission power. After practical application, it is found that the signal in some places cannot be shielded. Therefore, the units applying wifi disruptor should pay attention to the following points:
①Do not blindly use high-power jammers. The shielding effect can be achieved by applying a shield with a transmit power of about 2W in a classroom.
②After the end of use, it is necessary to turn off the jammer in time.
③Be sure to choose a wireless jammer produced by a regular manufacturer.
