Factors that affect the jammer and it can be used to maintain order

A signal jammer device is used to protect the order of the test site. There are many success stories. Cheating uses scientific and technological means and equipment. The jamming device is a technical guarantee to prevent fraud. We effectively maintain the order of the examination room. Related organizations are believed to have a reasonable understanding of this device. The environment of the test site is based on fairness and fairness. This is a responsible attitude for students. Enactment of examination room rules and maintenance of order are indispensable. Several aspects need to be considered when formulating and operating specific measures. Jammer employs advanced blocking technology. It can be adapted to complex work environments.We know that each interfering device has a different blocking range. In general, the higher the power, the longer the radius of interference. The higher the power, the larger the size of the jammer and the more cooling system is required. This is why desktop jammers usually have a wider range of interference than portable jammer. Therefore, before you buy a jammer, you need to determine the type of jammer you need and the range of interference you need. Both need to be taken into account. That way, you'll get what you need.The second factor is the interference of local signal strength or the distance from the signal tower. The closer the telephone signal tower is, the stronger the telephone signal and the worse the interference effect. If the local equipment is near the signal tower, the power of the mobile tower is usually much higher than the power of the jammer, so the small jammer may not work. It also emphasizes that using low-power jamming devices to block high-power devices such as high-power Bluetooth wireless routers may not work properly.First, when a gps signal jammer is manufactured, it is tested. There are many necessary tests such as battery life, transmission frequency, etc., including interference radius tests. Since these devices are often tested in open areas, manufacturers always believe that the test results are more effective than they really are. You know that buildings and various concrete structures can interfere with the transmission of signals. Most of us live in big cities and are surrounded by skyscrapers. The signal strength of the local mobile phone is also an influential factor. So if your interfering device can't block a phone within 30 meters, don't be surprised.
