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

The principle of mobile phone 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 jammer ranges from 1W to 100W. The transmission power of ordinary mobile phone jammer for examination and conference is between 10W and 60W.

In general, for general examination rooms and small meetings, choosing a mobile phone jammer with 2w-10w transmission power can achieve good interference effect. However, from our investigation of large schools and important meeting places, many places often unilaterally pursue high-power interference. For example, in a school with more than 20 classrooms, each classroom is equipped with a mobile phone jammer with a transmission power of 30W. In addition, after the examination, due to the lack of attention to the use, a small number of mobile phone jammers often fail to shut down in time and transmit interference signals for a long time. Especially in some primary schools, after the exam, the mobile phone jammer has not been turned off for two consecutive weeks.

Therefore, I strongly appeal to all those who need to use mobile Phone Jammer equipment:
1. Do not blindly select high-power mobile phone 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 jammer in time to avoid long-time startup and communication interference to surrounding residents.
3. Be sure to select the mobile phone jammer produced by the regular manufacturer. The mobile phone 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 jammer is turned on.
