How to solve the problem that a low-power full-band signal shielding device in the conference room cannot shield the mobile signal?

With the increasing popularity of mobile phones, there are more and more users, and many people do not pay attention to the occasion of use and do whatever they want. In some specific places such as conference rooms, courts, libraries, schools, etc., it needs to be used regulated. The noise generated by the frequent use of mobile phones spoils the quiet, serious atmosphere of these places. Affect people's normal work. It is difficult to have a significant effect simply by artificially requesting the prohibition of use. However, only one full-band signal shielding device is needed to solve the situation of indiscriminate use of mobile phones in the conference room, avoid personnel waste and reduce personnel costs.

The effective shielding distance of the full-band signal shielding device is closely related to the distance of the site base station. Under normal circumstances, a conference room within 200 square meters only needs a full-band signal shielding device to perfectly shield mobile phone signals. However, in some conference rooms, you will find that using a full-band signal shielding device, the telecom and China Unicom mobile phone signals can be shielded normally, but the mobile ones cannot be shielded or the shielding distance is relatively short. The root cause of this phenomenon is that the mobile phone signal of China Unicom/Telecom in this conference room is weaker than that of mobile phones, and the shielding effect is better than that of mobile phones. That is, the mobile base station is closer to the base station of China Telecom/China. The relationship between the full-band signal jammer and the base station is opposite. The two also transmit electromagnetic wave signals of the same frequency band, and the electromagnetic wave signals emitted by the full-band signal shielding device are to suppress the signals from the base station. A single channel of the full-band signal shielding device generally has a transmit power of 2-3W. If the base station signal is too strong, it cannot be suppressed. This will lead to the situation that the full-band signal shielding device cannot shield.

Then, in the same conference room, the full-band cell phone jammer can only shield telecommunications/China Unicom, but cannot shield the movement or the shielding distance of the movement cannot meet the requirements, how to deal with it?

The reason why the full-band signal shielding device cannot shield a certain operator is that the transmission power of the moving module in the full-band signal shielding device is too low to suppress the signal of the base station. At this time, the mobile module in the mobile high-power full-band signal shielding device can be added separately. The high-power full-band signal shielding instrument produced by topsignaljammer Technology Co., Ltd. is composed of independent modules. It can be used independently by a single module or by a combination of modules. For the situation where the mobile phone signal cannot be shielded, a mobile module can be added separately, combined with a low-power full-band signal shielding device to achieve full shielding.
