Wireless signal jammers are suitable for different jamming purposes and can provide communication protection. Keep the frequency free from any interference. In addition to wireless signal jammers, there are several other types of wifi jammer that are very useful for both personal and business information, and wireless signal jammers are very important.
The wireless signal jammer is an excellent jammer that can effectively block the signal, and this wireless signal jammer is not expensive. The wireless signal jammer will not affect the work of other electronic products around. This feature of the wireless signal jammer makes it very easy to use. In addition, wireless signal jammers are portable and come in different models and sizes. Therefore, it is ideal for shielding signals.
A wireless signal jammer is a very efficient and sophisticated device, it is a powerful device that can interfere with signals from 10-60 meters away. It is also possible to operate the wireless signal jammer with batteries and an adapter. So it can be used both indoors and outdoors. In other words, the advantage of this wireless signal jammer is that you can choose the installation location.
The shielding distance of a wireless signal jammer has a lot to do with the power of the device and the use environment. There are several aspects that contribute to the shielding effect: the first is the output power of the device, the second is the working mode of the shield, and the third is the use environment (indoor or outdoor), the fourth is the interference intensity of the surrounding environment.
How to ensure that the shielding effect of the wireless jammer can achieve the expected effect?
Wireless jammers are usually used in examination rooms, supervision places, confidential meeting rooms, etc. When using wireless jammers in these places, it is necessary to ensure that the shielding effect of the wireless jammers meets the expected effect. In fact, there are many factors that affect the shielding effect of the wireless jammer, such as the distance between the installation place of the wireless jammer and the nearby signal base station, the transmission power of the jammer, and the use of through walls. To ensure whether the wireless jammer can effectively shield mobile phone signals, testing is a very important step when purchasing a jammer.
First of all, test the shielding distance of the wireless jammer, don't just use one or two network types of mobile phones. The mobile phone networks used by cheating candidates during the exam are different, especially the 5G mobile phone network that has been very popular in the past two years. Therefore, it is necessary to test the mobile phones of all the networks of the current carrier. Ensure that the wireless jammer can block all mobile phone networks within the scope of an examination room, so that it is considered qualified!
Then test the stability of the shielding effect of the wireless jammer. Test the shielding effect after powering on to ensure that the mobile phone has no signal, and the mobile phone signal cannot appear from time to time, otherwise it will cause someone to use this intermittent time to send exam information. This time is enough for candidates to pass answers to cheat. Therefore, when purchasing a wireless jammer, you must pay attention to on-site testing of the shielding effects of different mobile phones to ensure that the jammer can truly achieve an effective shielding effect.
