With the popularity of mobile phones, the demand for mobile phone signal jammers in various meetings and examinations has greatly increased. Therefore, mobile phone signal jamming naturally has a broad market. However, most users lack sufficient understanding of mobile phone signal jammer. In order to achieve better results, one-sided selection of high-power Mobile Phone Signal Jammer will bring many hidden dangers.

The principle of mobile phone signal jammer is to use broadband to send interference signal to interfere with the uplink signal of mobile phone, so as to shield the working effect of mobile phone. Therefore, this itself is the origin of the signal. As a signal source, there will be radiation naturally. According to the use requirements, the transmission power of the existing mobile phone signal jammer ranges from 1W to 100W. The transmission power of ordinary mobile phone signal jammer for examination and conference is between 10W and 60W.

Therefore, I strongly appeal to all those who need to use mobile Signal Jammer equipment:
1. Do not blindly select high-power mobile phone signal jammer. For the classroom, choosing 2W transmission power shielding is enough to achieve the shielding effect.
2. In addition to the daily interference demand, after use, remember to turn off the mobile phone signal jammer in time to avoid long-time startup and communication interference to surrounding residents.
3. Be sure to select the mobile phone signal jammer produced by the regular manufacturer. The mobile phone signal jammer produced by informal manufacturers often pursues a large interference range. When debugging the equipment, it does not comply with relevant standards, resulting in the impact on the surrounding residents or operators' base stations after the mobile phone signal jammer is turned on.
