The proportion of netizens using mobile phones to go online increased from 81.0% in 2013 to 85.8%. The popularity of smart phones, the rapid development of smart hardware, and the continuous development of innovative applications have brought more convenience to people. Mobile phone communication not only gives people convenience, but also brings new challenges to the security and confidentiality of communications.
What countermeasures will I have for the new challenges that mobile communication poses to communication security? As it is said that it is one foot high and one foot high, the mobile phone signal blocker is an important device we use to ensure the security and confidentiality of communication. During the work process, the mobile phone signal blocker scans from the low-end frequency of the forward channel to the high-end at a certain speed. .
In the rapid development of mobile communications, mobile phones have become an indispensable communication tool for people. Mobile phones not only bring convenience to people's work, life and study, but also bring many disadvantages. Especially in schools, the school has a very headache in the management of students' mobile phones. Some students use mobile phones to cheat in the test room, which violates the fairness and justice of the exam. For this, we can use mobile phone signal blockers. Therefore, the mobile phone signal is blocked within the test room. Because the mobile phone signal is blocked, no mobile phone in the test room can receive and view, and calls and short messages from outside the test room cannot be transmitted to the test room. Similarly, the mobile phone in the test room cannot be dialed. Call and send short messages to ensure the fairness and justice of the exam. At the same time, the mobile phone signal shielding box can also be used for some confidential meetings.
According to the actual situation of domestic mobile communications, the shielding box research and development manufacturer has carefully developed a high-tech product mobile phone signal shielding box, which can block the mobile phone signal within a radius of 1-20 meters (50-250 square meters), making the mobile phone unable to make And answer, but will not interfere with the work of other e-learning equipment, when the mobile phone is not in the range, you can resume normal use. In function, it accepts sensitivity test and mobile phone test.
