Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.
[0038] For the convenience of subsequent explanations, the relevant terms are explained here:
[0039] A method for detecting and evaluating the effectiveness of wireless communication signal interference protection, such as figure 1 As shown, its specific steps are as follows:
[0040] Step (1) Division of the target scene.
[0041] Firstly, a target scene to be tested is selected, in which there are mobile communication signals of various operators. When the communication signal jammer is placed in the scene and before the communication signal jammer is turned on, only the original mobile communication signal exists in the target scene; and when the communication signal jammer is turned on, the original signal and the co...

The invention discloses an interference protection efficiency detection evaluation system and method of a wireless communication signal. The method is not to simply perform strength detection gradingon the interference, but is to detect useful signal and interference signal under the current electromagnetic environment and accomplish the full-signal space strength distribution prediction, the space interference-to-signal ratio is computed, and the efficiency evaluation is performed by combining the actual protection effect grading standard based on the interference-to-signal ratio; and meanwhile, a background data processing system is used for quickly predicting the whole space distribution in real time. Therefore, the secrecy effect of the whole secrecy occasion can be evaluated so as toacquire the secrecy protection level of the whole occasion, the field strength before signal shielding, the field strength after the signal shielding, the interference-to-signal ratio and like information. The signal field strengths of the whole occasion before and after the signal shielding can be predicted, the influence index by the human body by a dome and the secrecy occasion arrangement canbe analyzed, the collected data and the analyzed result are saved, the later analysis is convenient, and the interference efficiency of the communication signal interferer can be scientifically evaluated.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system and method for detecting and evaluating the interference protection effectiveness of wireless communication signals. Background technique [0002] The mobile signal communication signal jammer is a kind of shielding wireless communication signal for various examination rooms, schools, gas stations, courts, conference centers, government, finance, prisons, public security, military centers and other confidential places where the use of mobile phones is prohibited. Devices, most of which use suppressive interference to block downlink mobile communication signals. Although there are various signal and communication signal jammers in the market, the instruments for jamming performance evaluation are basically vacant. After joint research with China Mobile, China Unicom, Telecom, and Radio Management Committee, and market research with confidentiality units an...
