Radio waves can propagate freely in the air; it is difficult to avoid that cell phone signal jammer takes negative impact on the normal operation of the nearby mobile communications, while the cell phone signal jammer is used to achieve the interference effect in a specific area of mobile communication base station.
In addition to the interference signal, but also mobile phone jammer will have a larger energy microwave electromagnetic radiation while working. Although so far it has not been confirmed that how much harm will be brought by the electromagnetic radiation to people, but it is certain to say that this energy electromagnetic radiation is very harmful to human health. Theoretical analysis shows that excessive use of jammer in a small range like conference rooms and classrooms, microwave electromagnetic radiation energy will superimpose in a small space and was not outside the walls, ceilings, floors multiple reflections, it will cause exposure to in serious electromagnetic pollution in indoor staff. Many people reflect that the human body is often a lot of discomfort in the serious electromagnetic radiation environment; scientific experts said that excessive microwave electromagnetic radiation will cause headache, insomnia, skin or blood diseases.
Cell phone signal jammer is more often used in College entrance exams, candidates and teacher in the classroom installed with mobile phone jammer are irritability, inability to concentrate effort, individual candidates or even headaches, various phenomena that cell phone signal jammers will affect the normal thinking candidates in the examination room.

However, the application of cell phone jammer has aroused a heated debate in the society. The ones who approve of it argue that it guarantee that the examination can be carried on normally and creates a peaceful and equal environment for the candidates. The ones who are against it think that the radiation from the cell phone jammer may do harm to the human body, and will interrupt the function of other electronic equipments and block other networks. Well, it must be noted that the radiation from the cell phone jammer is relatively very low and thus the cell phone jammer is user friendly. As the cell phone jammer works in the same frequency as the cell phone, it is certain that the jammer only blocks the transmission between the cell phone and base station and has no influence upon the function of other devices and networks.
In company with raising of safety consciousness of the people, cell phone jammer has been widely used around the world to protect privacy. Nowadays, mobile phone jammer has been applied in various important places, such as schools, gas stations, churches, court, library, conference center, theaters, hospitals, government, finance, prisons, public security and military powerhouse.
The cell phone jammer shut down cell phone calls using a device which looked like a small portable radio with multiple antenna. The news station employee reported the incidents to the station, which prompted an investigation and the media attention.

The use of cell phones and other mobile communication devices, has brought us a lot of convenience, but sometimes their use will also have a lot of problems.mobile phone jammer is economical and effective solution to resolve these problems.
The phone is up and down dual-frequency operation. Regardless of whether the phone call, the phone and the base station are in constant contact to maintain registration to confirm the phone is running on your network. Once the call to the base station will be issued an instruction to inform the owners with the call, the signal on the phone, ringing the moment, the phone electromagnetic pulse. These pulses of electromagnetic waves on us a lot of electronic equipment generated a great deal of interference. Also due to the above reasons, the electromagnetic pulse generated by the phone calls in some regions and places can also cause great harm, and even endanger persons and property loss. Such as: remote scene of the explosion, hospital CCU, ICU ward, automation control room, refueling stations.
mobile phone jammer is to control more effective equipment. It is a signal blocking device, the use of the frequency sweep and point the combination of control technology, to cut off the signal contact between the wireless handset, a pager, mobile communication base station, blocking the normal working of the phone with the inter-base-station broadcast band (BCCH), reaches the blocking, inhibition, and the purpose of the truncated. Form a "quiet zone" in a particular place or area to control abuse of communications products, eliminate the interference, to ensure the health and safety purposes.
In the micro-Bo, students holding a civil and military views, there are many, many of them radical. The students zbsay, "claiming to be computer technology" home ", he suggested that anti-shielding against the fifth generation of jammers installed by the school.
The students questioned this there are security risks, claiming that anti-jammers protest. 12 at noon, see the dormitory corridor new cell phone signal jammers, a middle school student, civil and military, exclaimed "crying wolf". He bursts of microblogging protest, school dormitory engage in mobile phone signal jammers, rumors debugging Anyway, I am in the dormitory can not receive the signal, restrictions on freedom of communication.

Soon, all kinds of radiation spermicidal tumor radiation students say began to spread among students. In this regard, Huxiao Zhang said, in accordance with the product specifications, the product does not produce harmful radiation.
Yesterday, the Board of Education official said, the school installed phone signal jammers have been through parents, belonging to the internal management of the campus without getting the approval of the education sector.
