If there is a base station nearby,will it affect the jammer?
When taking some important exams, in order to prevent candidates from cheating through mobile phones and other communication devices, the signal jammer gps can always be seen in the exam room. As a tool that can effectively eliminate and prevent cheating, schools and teachers are accustomed to it, but some issues are still unclear. For example, if there is a base station near the examination room, will the effect of the signal jammer be affected?
Because the base station itself has a strong magnetic field, and the strength of the magnetic field will affect the shielding effect of the test signal shielding, so when the test room is put into use, you may wish to use it first to see how much the actual shielding range is. Then we need to decide how many machines we need based on this actual data. This needs to be taken seriously, otherwise there will be places that are not blocked. But whether or not testing the jammer will be affected, a better performing, more professional machine is a must.
When the mobile phone is working, it is within a certain frequency range. The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. Most of the signal jammers shield mobile phone signals by transmitting interference signals. By transmitting a high-power signal of a certain frequency, the surrounding electromagnetic environment is severely damaged, and the mobile phone cannot normally obtain and analyze the signal from the base station, so as to achieve the purpose of shielding the mobile phone signal.
The base station itself will generate a strong electromagnetic signal when it transmits signals to the surroundings, and the electromagnetic signal emitted by the base station, as the distance increases, the electromagnetic signal of the field strength will also correspond. The strength of the electromagnetic signal is one of the most important factors affecting the shielding effect of the mobile phone signal jammer. The field strength of the electromagnetic signal will also correspond. The strength of the electromagnetic signal is one of the most important factors affecting the shielding effect of the mobile phone signal jammer. The field strength of the electromagnetic signal will also correspond. The strength of the electromagnetic signal is one of the most important factors affecting the shielding effect of the mobile phone signal jammer.
However,if there is a communication base station near the examination room, the strength of the transmitted signal will be stronger and more stable, and it will be less likely to be interfered by the signal jammer. The shielding effect of the signal jammer will naturally be greatly reduced. So what do you need to do to achieve a stable and reliable shielding effect? In fact, it is very simple, that is, increase the power of the signal jammer.As long as the power of the signal jammer increases, the strength of the interference signal will also increase, and naturally you can achieve better good shielding effect
