dojammer signal blocker

 If you want to make a  frequency jamme r, you can determine how many frequency bands to make based on the WiFi frequency distribution at the site. If the site requires the interference range of the frequency jammer to be relatively small, with a radius of about 10-20 meters, then you can use a low-power frequency jammer module, which can basically meet the requirements of on-site shielding. Of course, it also depends on the distance between the WiFi signal source and the frequency jammer. The closer the mobile phone or WiFi receiving device is to the shield, the better the interference effect will be. The closer the distance between the mobile phone or WiFi receiving device and the WiFi signal source, the worse the shielding effect will be than the same distance at the far end. If the site requires the interference range of the frequency jammer to be relatively large, with a radius of about 20-100 meters, then you can use a medium-power frequency jammer module, which can basi...

 Customers purchase  high-power signal jammers  and are in a hurry to get the goods, so they think of air transport. Why are some items with built-in batteries allowed to be shipped by air, while some items or equipment are prohibited from being shipped by air? That is because batteries are different, and the classification and identification of batteries is also complicated. Some batteries or equipment with built-in batteries may be dangerous goods involving air transport items 4.3, Class 8 and Class 9, while some are conventional ordinary batteries with low battery capacity, which are allowed to be shipped by air. So can things with batteries be shipped by air? It cannot be said that it can or cannot be, but it still needs to be analyzed based on the specific product. So how to determine whether a signal jammer with a battery can be shipped by air? The answer is one: the equipment to be shipped by air must have an appraisal report issued by a professional appraisal agen...

 With the rapid development of 5G technology, 5G networks have been widely used around the world. However, in certain specific occasions, such as schools, prisons, examination rooms, etc., 5G signals need to be shielded to ensure fairness, safety and order. Therefore, as an emerging electronic device, the importance of 5G Jammer is becoming increasingly prominent. The working principle of  5G Jammer  is based on electromagnetic interference technology. It forms a high-intensity electromagnetic field by emitting radio waves with the same or similar frequency band as the 5G communication band. When these waves meet the 5G signals received by mobile devices such as mobile phones, an interference effect will occur, causing the signal strength to weaken or even disappear completely, thereby shielding the 5G signal in the area. This process is similar to the sound emitted by two different sound sources meeting at the same frequency, which may cause interference and cause sound ...
