Please use the phone signal jammer with caution!

Now that mobile phones have been popularized in all directions, everyone has their own mobile phone, but this also increases the requirements for phone signal jammers a lot, so the phone signal jammer market has a huge development space. But now many customers don't know much about the specific role of signal shielding equipment. In order to achieve good results, some companies often listen to unscrupulous salesmen bragging about buying high-power telephone signal jammers, which leads to some unscrupulous Necessary trouble occurs. Therefore, when we choose signal shielding equipment, we must choose the equipment that suits us according to our personal needs. Below, Chengdu 8341 Information Technology Co., Ltd. will explain to you the working principle of this aspect.

The working principle of the cell phone signal jammer is to interfere with the electronic signal sent by the mobile base station by transmitting in a special frequency band, and the transmitted signal will forge the base station signal to achieve the function of blocking the mobile phone signal. In fact, this is a signal shielding emission source. But these signal sources will also have some problems, that is, the source of electromagnetic radiation. According to the needs of the scene, the power emitted by today's phone signal jammers is different from 1W to 100W. How strong is this transmission power? We can only make a comparison. The transmission power of the largest GSM mobile phone is 2W, and the general transmission power of GSM macro base stations is between 20W-40W. The transmission power of the telephone signal jammer generally used for examinations and meetings is between 10W-50W.

Generally speaking, for general examinations and small and medium-sized conferences, choosing a telephone signal jammer with a transmission power of 2W-10W can achieve good results. But for the inspection of major schools and major meeting places, many places are usually superficial pursuit of high-power telephone signal jammers, for example: a college with more than 20 classrooms, each classroom is equipped with a signal jammer Shielding equipment, and the choice refers to the transmission power of 50W, and after the test, because of insufficient attention, it often occurs that a small shielding signal equipment cannot be turned off immediately, and the phenomenon of continuous transmission for several weeks. Especially in a certain elementary school, after a test, the phone signal jammer was not turned off for 2 weeks. It was not until everyone checked and went to the scene that they realized that the phone signal jammer was constantly on the side of the classroom platform full of students. open! This really made us break out in a cold sweat!

Therefore, I strongly recommend that companies that must use telephone signal jammers:

1. Do not blindly follow the trend and choose a high-power telephone signal jammer. For a classroom, choosing a shielding signal device with a transmission power of 2W is enough to achieve the actual effect of shielding.

2. After finishing the trial, try to turn off the phone signal jammer as soon as possible, so as not to cause continuous radiation source.

3. Try to choose reliable manufacturers to produce telephone signal jammers. Non-regular manufacturers usually produce telephone signal jammers to increase the transmission power intentionally in pursuit of obvious shielding effect.
