Cell Phone Jammer Pcb

The wireless communication technology is developing rapidly. 5G is currently in the trial operation stage. Yesterday, the system could be completely shielded, and there may be problems today. Therefore, the construction of the shielding system should be modularized and can be easily upgraded according to the changes of the surrounding communication facilities, so that the project investment can be substantially saved and permanent shielding can be achieved. Factor 1: cell phone jammer Pcb Effectiveness of shielding The effectiveness of mobile phone signal jammers refers to whether the shielding effect has blind spots or leaks. Near some prisons, there may be sources of strong mobile phone signals. In order to achieve a good shielding effect, a lot of materials and energy will be spent correspondingly, and the cost will correspondingly increase substantially. Therefore, the better the shielding effect, the higher the cost. In actual use, the shielding requirements of the prison area are generally higher, and there are some leaks and blind spots. Some personnel may seize this loophole. This makes it possible to use mobile phones in the originally prescribed shielding area, which cannot achieve the original intention of shielding mobile phones.

Factor two: the trouble-free time of the mobile phone signal jammer. If the original stipulation that the trouble-free service life is 1 year, and the actual use of the trouble-free period reaches 3 years, the cost performance has tripled. If the original stipulation that the trouble-free service life is 1 year, it will often fail in less than half a year in actual use. Although it is a free warranty, the risk is immeasurable, personnel resources are wasted, and the corresponding price-performance ratio is greatly reduced. Factor three: Cell Phone Jammer Pcb External shielding If external shielding is not considered, it is relatively easy to simply shield mobile phone signals, just increase the shielding power. But it is necessary to ensure that the shielding area has no blind areas and no leakage points. The power intensity in the shielding area is relatively high. If there is a little leakage, the external shielding will be large. This requires full consideration and technical control during shielding design to achieve precise and efficient shielding without external coverage. Factor 4: The cost of mobile phone signal jammers must follow the shielding requirements and budget. You cannot blindly choose cheap machines, and you cannot think that expensive is good. In the actual choice, word-of-mouth is very important. It is also necessary to conduct a field investigation of its past cases. Try the shielding effect, and then do the selection.
