Will the communication base station affect the signal jammer for the exam?
The communication base station will indeed have a certain impact on the signal jammer for wifi used for the exam, especially when the base station is close to the examination room (usually within 500 meters). The main reasons include:
The base station signal strength is strong
As the signal source of mobile phone communication, the base station has a much higher transmission power and signal strength than ordinary mobile phone devices. Near the examination room, the strong radio signal emitted by the base station will cause the jammer to generate a stronger interference signal to effectively cover and shield these strong signals.
The electromagnetic field of the base station affects the operation of the jammer
The electromagnetic field generated by the base station antenna will interfere with the working environment inside the jammer, which may affect the RF output and signal stability of the jammer, resulting in a decrease in the shielding effect.
The coverage range of the jammer is limited
Due to the need to counter strong base station signals, the effective shielding radius of the jammer may be compressed, and the originally expected coverage range will be reduced, resulting in the signal in some areas not being effectively shielded.
Necessity of debugging in practical applications
Therefore, when installing signal jammers in the examination room, on-site tests should be carried out in advance to evaluate the base station signal strength and the actual coverage effect of the jammers, and adjust the number and layout of the jammers according to the actual situation to ensure that there are no blind spots.
It is particularly important to choose high-performance equipment
For environments with strong base station signals, professional-grade jammers with sufficient power, comprehensive frequency band coverage and strong anti-interference ability can more effectively overcome the challenges brought by base station signals and ensure that the signal shielding effect during the examination is stable and reliable.
In summary, when the base station is close, it will affect the effect of the test signal jammer. It is necessary to reasonably arrange and select equipment in combination with the on-site environment to ensure that the signal is effectively shielded during the examination and maintain a fair and just examination environment.
