Everyone has a cell phone now, even students now have a cell phone. This is great because it is easier and more convenient for their parents to contact them and find out about their condition. But we realized that if students were using their phones there were a lot of negative issues, and that was a big problem! More and more teachers are annoyed by this and want to find a solution to the problem. What if there was a device that could block the noise? What if there is a device that can keep student phones from working? In fact, with a portable cell phone jammer, the problem can be easily solved. Usually mini cell phone jammer are small enough to fit in your bag, but they make a great distraction so students can't figure out why they can't use their phones to chat online, make calls, send messages, etc.

The prison shielding system works like other mobile jammers, but with a little bit of high tech. Smart Prison Blocker can not only block unsolicited calls inside the prison but also allow only authorized calls. It is mainly used in prison cells, military facilities and courts. It is a smart device that can be managed automatically or manually to detect and block unauthorized calls in the corresponding area. It works like a well-managed access point or gateway that manages all incoming and outgoing calls within range, and controls all of them based on manually stored instructions or automatically. The device is used to control cell phone activity in prison areas. It works well to block unauthorized calls and allow authorized communication activities. These signal jammer devices are administered through a central system. They have the right to allow or deny communications at any time. These high-tech cell phone signal jammer devices have the advantage of being operated remotely. This means that if the managed area is far from the control center, the device can be activated or deactivated at any point by using the remote on/off function.

Signal jammers can make your surroundings quieter

When the WiFi isolator is working, if the transmission power is too large due to the improper setting, in a small-scale conference room, classroom and other confined spaces, the electromagnetic waves are superimposed in the narrow space, and the electromagnetic waves will pass through the walls, ceilings, and floors that are originally separated from the outside for many times. The reflection will make the people in the room in more serious electromagnetic pollution. According to the survey, the college entrance examination and high school entrance examination are the occasions where wifi jammer are used the most, and in some test rooms that use WiFi jammers, some parties (gaokao inspectors, candidates and teachers) are in a state of irritability and inability to concentrate. Some candidates even Headache symptoms occur. There are various indications that if the transmission power of the WiFi jammer is too large, it will seriously affect the normal thinking of candidates in the examination room. When you really need to use a WiFi jammer, try to use a low-power WiFi jammer. If one can solve the problem, don't set up multiple ones. The lower the installation position, the better. Do not hang it on top of people's heads, which is very detrimental to human health. The WiFi signal jammer we set up during the county economic work conference in the province was placed in the flowers on the floor beside the wall of the conference room, which not only achieved the shielding effect, but also did not affect the beauty of the venue. It can be said that it is the best of both worlds.

The rapid development of wireless communication has greatly facilitated the lives of people all over the world. But criminal abuse has seriously damaged people's lives and impartial law enforcement. Prisoners use wireless communication devices to conduct illegal activities with outside guerrillas. They ordered the murder of witnesses and attempted to be acquitted, even sparking riots to escape from prison. The competition of gps jammer is getting more and more fierce. In order to greatly reduce the cost, some unscrupulous traders buy cheap second-hand dismantling devices for new GPS jammers, which will greatly shorten the service life of the equipment and the result. At present, China Unicom and China Mobile, including China Telecom, have already launched their own 4G frequency bands. Some GPS blocker manufacturers can block a frequency band that you can block called 4G. Very irresponsible to consumers. We know that every high-tech product was invented because people had this need, like a cell phone, because it was easier for those who needed it to communicate than before, including 4g phones that are now commonplace. But the 4g signal that many people are using these days and people who suffer from loud phone calls complain and make sure it's quiet in places like conference rooms, classrooms and late at night where people need to sleep a GPS jammer is a must for people.
