GPS signal jammer can block the GPS signal in a specific area　

　　In the use of GPS signal jammer crowd, some to avoid cheating in the exam, some for the quiet meeting or confidential information, these are out of good wishes and purposes. But there are also selfish interests.

　　For example, the owner of a public telephone may use a jammer to interfere with the mobile communication base stations around his business location, so that the people around the public telephone that they operate are not very easy to use.

　　And use public telephones to increase their economic benefits. In addition, mobile communication operators may also use shielding to harm the interests of others, thereby gaining an advantage in some local competition in the same industry. In addition, the GPS signal jammer is also very easy to add software to become real monitoring equipment.

　　As radio management and Security Bureau and other functional departments, in view of the increasing application of GPS signal jammers in all walks of life, it is necessary to strengthen the control and standardization of such equipment.

　　As we all know, the characteristics of the free propagation of radio waves in mid-air, the GPS jammers can block the signal of the mobile communication base station in a specific area and achieve its limited purpose, but it will also damage the health of varying degrees. Therefore, it is necessary to Use this device with caution.

　　Theoretical analysis shows that when the device is working, if the transmission power is too large due to unreasonable settings, in a small-scale conference room, classroom, and other confined spaces, the electromagnetic waves accumulate in the narrow space, and pass through the walls and ceilings that were originally separated from the outside.

　　Among the people who use GPS signal jammers, some are for the sake of avoiding cheating in exams, and some are for the sake of the silence of the venue or confidential information in meetings, all for good wishes and purposes.

　　But there are also selfish interests. For example, the owner of a public telephone may use a jammer to interfere with the mobile communication base stations around his business location, so that the people around the public telephone that they operate are not very easy to use. And use public telephones to increase their economic benefits. In addition, mobile communication operators may also use shielding to harm the interests of others, thereby gaining an advantage in some local competition in the same industry. In addition, the GPS signal jammer is also very easy to add software to become real monitoring equipment.

　　The above list is what people use the device for, but whatever the purpose, it should not be obtained at the expense of large-scale mobile communication. In fact, according to the study, the device can be installed without affecting normal applications of mass mobile communications.
