What are the factors that affect the cost performance of mobile phone signal jammers?
Factor 1: Effective shielding
The so-called effective shielding refers to whether there are blind spots or missing spots in the signal jammer effect. Near some prisons, there may be base stations with 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 cost will increase accordingly. In actual use, the shielding requirements of the prison area are generally higher, and there are some leaks and blind spots. The offenders may seize this loophole, so that the mobile phone can be used in the originally prescribed shielding area, which cannot achieve the original intention of shielding the mobile phone.
Factor 2: No failure time
If the original stipulation that the failure-free service life is 1 year and the failure-free service reaches 3 years in actual use, the cost performance is tripled.
If the original stipulation that the failure-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, the personnel resources are wasted, and the corresponding cost performance is greatly reduced.
Factor 3: External interference
If external interference is not considered, it is relatively easy to simply shield, 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 interference will be great. This requires full consideration and technical control in shielding design to achieve precise and efficient shielding without external interference.
Factor 4: Cost
The cost should follow the shielding requirements and budget. You cannot blindly choose cheap products, and you cannot think that expensive is good. In actual choices, word-of-mouth is very important. It is also necessary to conduct field inspections of past cases, test the shielding effects, and then make selections.
