The function of the wireless signal jammer is to shield the signal, and it is used in many occasions. The most common use case we come into contact with is the examination room. When we use the wireless signal jammer, you will find that within a certain space, as long as you turn on the switch of the wireless signal jammer, there is no way for everyone's mobile phone to search for the signal, that is, if When you use a wireless signal jammer, you cannot use your mobile phone. So do you know what the shielding effect of the wireless signal jammer is related to? Let's find out together!
The power of the wireless signal jammer is certain. In a space without obstacles, the shielding range is determined by the path attenuation of the received signal and the signal level of the receiving base station. In order to realize the interference of the wireless signal jammer on the mobile network, it must be ensured that the signal field strength emitted by the wireless signal jammer is greater than the field strength in the interference area, because the closer the base station, the stronger the field strength and the shielding effect will be attenuated. On the contrary The farther the interference location is from the base station, the better the shielding effect of the wireless signal jammer will be.
It can be seen that within a certain power range, the shielding effect is mainly determined by the field strength in the interference area. No matter how large the power of the wireless signal jammer is, as long as the transmission power is a fixed value, the strength of the interference signal will increase as the distance increases. will gradually decrease, thus losing the shielding ability. Therefore, the shielding effect of the wireless signal jammer is related to the output power and the signal strength of the base station.
The wireless jammer has been trusted by examination rooms, schools, prisons and other units
The wireless jammer has been trusted by examination rooms, schools, prisons and other units. In recent years, mobile phone cheating in various examinations across the country has occurred from time to time, seriously affecting the fairness and impartiality of the examination. In this regard, it is stipulated that wireless jammers will be set up during the exam to create a healthy and fair exam environment for candidates.
Therefore, the wireless jammer has come into everyone's sight, and it is learned that the wireless jammer is used for candidates to cheat with their mobile phones. I believe that people who have experienced the big exam are familiar with it. Before the exam, I heard that a wireless shielding system may be installed in this examination room.
It can be used not only in student dormitories, examination rooms, office meeting rooms, but also in prisons and military operations. With the progress of society and the development of technology, wireless jammers have become an indispensable part of people's lives. For middle school students, wireless jammers are an important factor affecting their lives. Using mobile phones for a long time will affect eyesight, and more seriously, it will affect children's study. Therefore, a wireless signal shielding system will be installed in the dormitory to prevent students from playing with mobile phones at night and affecting their sleep.
For many families, children are addicted to online games and various video software. Parents are very distressed, so they put wireless jammers in their children's rooms to prevent children from calling when they are not sleeping and delaying their studies.
