Perfectjammer 2022/06/02

The test room-type mobile phone signal jammers are all omnidirectional, and are generally installed on the top of the classroom wall and near the base station, so that the classroom signal can be shielded in all directions, the connection between the mobile phone and the base station can be blocked, and the normal learning of the student door can be guaranteed. healthy. Conference room type Block Harassing Calls On Cell Phone Generally, it is omnidirectional. It is generally used in the meeting in the company to prevent employees from playing mobile phones during the meeting and being unable to listen to the leader's speech from destroying the atmosphere of the meeting. The mobile phone signal jammer is installed on the top wall of the conference room, which can fully cover every dead corner of the conference room. Factory-type mobile phone signal jammers are directional, and the installation location is generally installed on the top of the factory workshop and outdoors to prevent employees from playing mobile phones at work. After installation, the production efficiency is greatly improved.

The basic principle of 5G mobile phone signal jammer is actually not difficult. As a mobile communication technology equipment, a mobile phone must first establish a connection with the surrounding communication base stations when communicating, and then connect to the base station equipment to find the communication arrival station. In the above whole process, all information content is installed and transmitted according to radio waves. The frequency band of radio waves commonly used by mobile phones is related to the common style of mobile phones and the carrier they belong to. But in general, the three operators use radio frequency bands in the 850-4900MHz range. If you want to block the mobile phone signals in the test room, it is unlikely that the 2G/3G/4G/5G communication base stations of each operator around the test room will not work, otherwise all the communication equipment in this area will be paralyzed. Can't communicate properly. Since it is not possible to shield from the operator, the only way is to shield the mobile phone signal in the test room. Shielding the mobile phone signal can reasonably avoid the situation of fraudulent use of mobile phones, thereby avoiding all fraudulent personal behaviors. In general, the Block Harassing Calls On Cell Phone effective range is within 25 meters, and ideally a machine can provide a total area of ​​100 square meters of interference. cell phone jammer The total output power of the transmission should not be too high, otherwise it may cause a certain amount of radiation to the body. Long-term exposure to radiation can cause damage to the human body. Therefore, when purchasing a jammer, not only the scope of efficacy, but also the scope of efficacy should be considered. output power to the machine.
