The annual college entrance examination and high school entrance examination are coming soon, and the construction and preparation of standardized examination rooms are in progress. It is almost a must to install signal jammers in each examination room, so the education authorities or school leaders are choosing signal shielding equipment. When testing, the corresponding technical indicators and functional requirements will be put forward, so the question arises: Does the signal jammer in the examination room need to have many auxiliary functions? Are there more functions to better meet actual needs?
The so-called test room signal jammer is not just to shield mobile phone signals. It is actually a general name. The types of shielded signals it emits usually include Wi-Fi signals, Bluetooth signals and wireless data transmission , walkie-talkie communication, remote control cheating tools, etc. To evaluate whether the signal jammer in the examination room is good or bad, the first criterion is: whether it achieves effective shielding effect. The second basis for judging is: the distance or range where various signals are effectively shielded. When these two key technical indicators are met, other auxiliary functions will be assessed.
Nowadays, there are many manufacturers that can produce signal jammers for examination rooms, and each manufacturer has developed and launched many auxiliary functions around the products, such as:
1) Based on the Internet networking protocol, a large number of test room signal jammers are intelligently networked to realize remote intelligent control and management functions;
2) Turning on or off any frequency band in the shielding device can also realize the function of adjusting the transmission power;
3) Display the working status of the device through the LED indicator light or LCD screen;
The above is just a list of some representative auxiliary functions, not all of them. So in the actual use process, do customers have to require all these functions? In fact, not necessarily. We believe that these functions are only auxiliary after all. For the signal jammer in the examination room, these functions only play a role in strengthening intelligent management, and have no effect on the final signal shielding effect. Or to put it more bluntly: these auxiliary functions are icing on the cake.
