What you don’t know about cell phone jammers.
With the popularity of mobile phones, the demand for cell phone jammers in various conferences, exams, etc. has gradually increased, thus opening up a broad market for mobile phone jammers. However, there are still many users who do not know enough about mobile phone jammers and think that using high-power mobile phone jammers can achieve better results. In fact, this idea is wrong and there are great safety risks.
The working principle of the signal blocker for sale is to use broadband to transmit interference signals to interfere with the uplink signals of the mobile phone, thereby shielding the work of the mobile phone. So, this itself is a signal transmitter. The signal transmitter will produce radiation. According to the usage requirements, the current shielding transmission power range of mobile phone jammers is between 1W and 480W.
Generally speaking, for general examinations and small meetings, using a topsignaljammer electronic mobile phone jammer with a transmission power of 2W-10W can achieve good results. However, surveys of major schools and important conference venues reveal that many venues only pursue high-power shielding. For example, in a school with more than 20 classrooms, each classroom uses a mobile phone jammer and selects a 30W transmit power. After inspection, it was often found that the jammer was not closed in time due to improper use, resulting in continuous emission for several weeks.
