In prisons, detention centers and other regulatory institutions, mobile communication tools such as mobile phones are not only explicitly prohibited from use by criminals, but also by supervisors. Once the mobile phone is brought into the prison and used in violation of regulations, it will cause great harm to the prison management. Some criminals have illegally brought in mobile phones to make calls, send text messages and receive information, and even form gangs to escape from prison. Therefore, it is urgent to install prison signal jammers in prisons and other regulatory institutions. So when the prison jammer signal is working, there are still some shielding blind areas that are not completely covered, how to solve it?

Prison signal jammers are generally more used in prisons or detention centers, because prison signal jammers have a larger interference range and require fewer installations, so they are very popular among customers. However, within the high walls of the prison, the interference frequency band will also be affected by the building walls, and the number and height of the buildings in each prison are different. The distribution direction and terrain of the base stations around each prison are different, so the strength of the mobile phone signal transmitted from the base station is also different. The layout of the prison signal jammer in each prison needs to be designed according to the actual situation. Even in the same environment, the base station signal will be affected by air humidity, which will also cause fluctuations in the signal field strength. In addition, there are differences in field strength between indoors and outdoors. Metal objects have very complex negative effects on cell phone shielding signals. Therefore, there will be partial shielding blind spots. Therefore, it is recommended to use the prison signal jammer with large and small powers together in the prison. When there is a shielding blind spot, use a low-power prison signal jammer, which can solve the problem of shielding blind spots.

We want the mobile phone jammer to achieve the expected shielding effect, what should we do?

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 the wall. 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 turning on the phone to ensure that there is no signal on the mobile phone, and the mobile phone signal cannot appear from time to time, otherwise someone will 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.
