Although the time for the college entrance examination this year was affected by the epidemic and was postponed to July 7-8, in order to ensure the information security of the examination room, the corresponding measures have not been reduced at all. Operators have issued announcements that during the exam period, the wireless signal jammer will be turned on in accordance with the requirements of the Education Bureau, which will affect the communication quality of mobile phone users around the school. The communication will not return to normal until the end of the exam.

The principle of shielding mobile phone signal with college entrance examination jammer

The cell phone signal jammer scans from the low frequency band of the forward channel (the channel from the signal tower to the mobile phone) to the high frequency band at a certain speed during the working process, and forms interference when the mobile phone receives the message signal, so that the mobile phone cannot detect The normal data sent by the base station prevents the establishment of a connection with the base station and presents a state of no signal and no service.

At present, the mobile phone signal jammers used in the examination room are all full frequency bands, which can affect all the frequency bands of the three operators 2G/3G/4G/5G, and WIFI signals and Bluetooth signals can also be shielded.

Finally, Texin Electronics wishes the majority of candidates a victory and a title of gold list!
