With the popularity of mobile phones, the demand for full-band jammers in various conferences and examinations has also increased significantly, so full-band frequency jammers naturally have a wide market. However, the vast majority of customers lack sufficient understanding of full-band jammers, and often choose high-power full-band frequency jammers one-sidedly for better results, causing many hidden dangers.
The principle of the full-band jammer is to transmit jamming signals through broadband to interfere with the uplink signal of the mobile phone to shield the mobile phone from working. It is therefore a source of signal emission in itself. Since it is a signal emission source, there is naturally radiation. The current full-band frequency jammer has a transmission power ranging from 1W-100W according to the needs of use. How strong is this transmission power? For comparison, the maximum transmit power of a GSM mobile phone is 2W, and the usual transmit power of a GSM macro base station is between 20W and 40W. The transmission power of the full-band jammer generally used for examinations and meetings is between 10W-50W.
Usually, for general examinations and small meetings, choosing a full-band jammer with a transmission power of 2W-10W can achieve good results. However, according to our investigation of major schools and important meeting places, many places are often one-sided in the pursuit of high-power full-band frequency jammers, for example: a school with more than 20 classrooms, each classroom is equipped with a full-band jammer I chose a 50W transmission power, and after the test, due to the lack of attention to the use, there will often be a small number of full-band frequency jammers that are not turned off in time and continue to transmit for several weeks. Especially in a certain elementary school, after a certain exam, the full-band jammer was not turned off for 2 weeks. It was not until we went to the scene that we found that the full-band frequency jammer was on the side of the classroom full of primary school students. open! This really made us break out in a cold sweat!
Therefore, here I strongly appeal to all major units that need to use full-band jammers:
1. Do not blindly choose a high-power full-band frequency jammer. For a classroom, choosing a full-band jammer with a transmission power of 2W is enough to achieve the shielding effect.
2. After use, be sure to turn off the full-band frequency jammer in time to avoid continuous radiation.
3. Be sure to choose a full-band jammer produced by a regular manufacturer. A full-band frequency jammer produced by an informal manufacturer often deliberately increases the transmission power in order to pursue a good shielding effect.
The 5G mobile phone signal jammer is a new type of information security product. It uses specific electromagnetic signals to form a shielding network where it needs to be protected, so that the mobile phone cannot receive data from the base station and cannot establish contact with the base station. What should be paid attention to when installing it? ? Let's take a look at the detailed introduction of the staff.
1. Before installing the device, the antenna must be installed correctly according to the signs, and then turn on the power to prevent the machine from burning out.
2. Before installing the equipment, you must first understand the direction of the base station, and try to make the direction of the jammer follow the direction of the base station.
3. When installing the equipment, pay attention to whether there are metal objects within 1 meter around the machine to prevent signal reflection and affect the shielding function.
4. Special environments such as gas stations and gas stations should be equipped with explosion-proof machines.
5. The height of the device is preferably 1.8-2 meters. It can be placed directly on the table, and can be installed on the wall or ceiling. It is better for the antenna to be perpendicular to the ground.
6. If it is installed indoors, attention should be paid to whether the transmission frequency of the wireless device causes co-channel interference.
7. The anti-interference ability and safety interval of the existing indoor precision instruments and meters must be considered.
8. If there are amplifiers such as signal boosters in the room, it is not suitable for device shielding.
The above is the relevant introduction to the installation precautions of the 5G mobile phone signal jammer. I believe you have understood it. If you have any other questions, you can consult us.
