Method for shielding wireless signal

Abstract

The embodiment of the invention discloses a method for shielding a wireless signal. The method includes the steps that (1) a monitoring unit receives a user instruction, wherein the user instruction is a modification instruction or an inquiry instruction; (2) the monitoring unit judges the user instruction, if the user instruction is the inquiry instruction, shielding parameters are fed back to a user, and if the user instruction is the modification instruction, the monitoring unit judges whether the modification instruction is in a manual control mode or an automatic control mode, if the modification instruction is in the manual control mode, a manual control process is started, a power control signal is transmitted to multiple frequency band shielding units, and if the modification instruction is in the automatic control mode, an automatic control process is started, and the power control signal is transmitted to the multiple frequency band shielding units; (3) the frequency band shielding units radiate shielding signals in multiple frequency bands according to the power control signal. According to the method, the shielding signals can be flexibly controlled, a wireless signal shielding device can be monitored in real time, the power level of the wireless signal shielding device can be accurately adjusted, dynamic upgrading can be achieved, wireless signals possibly occurring in the future can be shielded, and the signal shielding effect can be optimized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless signal shielding method. Background technique [0002] With the rapid development of wireless communication technology, terminals such as mobile phones and walkie-talkies are popular among users due to their convenience, speed, and freedom from time and place restrictions. One of the indispensable tools in . While wireless communication technology brings convenience to people, it also brings negative impacts, such as using wireless communication equipment to cheat, stealing user privacy, and mobile phone noise interference. Therefore, in many occasions, people wish to shield various wireless signals in a certain area. For example, shield the wireless signals in the examination room to prevent the possibility of cheating by radio and maintain the fairness of the exam; shield the wireless signals in important conference rooms to prevent the leakage of state secre...
