There is no relevant specification for the installation position of jammer
The construction principle of the mobile phone signal jammer is too simple. Anyone who knows a little about electronic information technology can build it. Therefore, the quality of this item in the market is uneven. Do not send a machine that costs tens of dollars or even one or two hundred. I hope it can work all day and in all frequency bands. People are dizzy, not to mention simple electronic components. Therefore, the high equipment failure rate is one of the factors that cause the poor effect of shielding. Even then, it can't be said that is useless at all. The facilities processed by reliable manufacturers and approved by my country's wireless management method agency can also realize the dream shielding effect. When the mobile phone is completely manipulated by the blocker, it is really useless except to check the time. Therefore, the Education Bureau can also block the internal communication signals of the examination room to the highest degree by opening 88 during the Chinese examination period. It is fair and reasonable to maintain and maintain the examination. Even if the common faults of the shielding device in a classroom caused by various factors cannot work normally, the coverage area of the shielding equipment opened in the nearby examination room will be accumulated in this area, thereby completing the passive operation of this area. Block out.
