In the examination room of many large-scale examinations, in order to prevent students taking the examination from carrying their mobile phones without permission, secretly using mobile phones to contact the outside world during the examination and cheating in the examination, the installation and use of mobile phone signal jammers in the examination room is the most commonly used technical protection means . However, with the progress of the times, the peripheral electronic products that match mobile phones have flourished in recent years, such as smart watches or electronic bracelets, etc. Some smart watches can even be completely separated from the mobile phone, and can communicate with the outside world and communicate with the outside world by themselves. For data transmission, the question arises: can the mobile phone signal jammers commonly used in examination rooms block smart watches?
If you carefully understand the functions and technical parameters of smart watches, you can know that no matter what the appearance of these smart watches is, or there are more or less differences in functions, there will be no obvious difference in their basic communication modules, or It uses the WIFI module to bind with the mobile phone to complete the communication, or it has a built-in SIM card, which is equivalent to a simplified version of the mobile phone. After this analysis, the questions raised above are easy to answer: since the mobile phone signal jammer in the examination room can completely shield all mobile phones, the smart watch is almost equivalent to a simplified small mobile phone, so the mobile phone signal jammer in the examination room Smart watches can also be blocked.
Some students may be lucky enough to think that electronic products such as smart watches or electronic bracelets can be brought into the examination room. As everyone knows, in any formal examination, not only the mobile phone signal jammer in the examination room will directly block and block the signal, even such electronic products When the product enters the examination room, the invigilator will fail to pass the inspection with a metal detector.
