What are the factors that affect the effect of cell phone signal jammers?

Factor 1: Shielding Effectiveness

The so-called shielding efficiency refers to whether there are blind spots or leaks in the shielding effect. In the vicinity of some prisons, there may be transmitting base stations with strong mobile phone signals. In order to achieve a good shielding effect, it will take a lot of materials and energy accordingly, and the cost will increase accordingly. Therefore, the better the shielding effect, the higher the cost will be. In practical applications, the requirements for signal blocker in the prison area are generally higher, and there are slight leaks and blind spots. The offenders may seize this loophole, so that the mobile phone can be used in the original shielded area, and the original intention of shielding the mobile phone cannot be achieved.

Factor 2: No downtime

If the original non-fault service life is 1 year, and the actual use of the fault-free service reaches 3 years, the cost performance will be tripled.

If the original fault-free service life is 1 year, and the actual use is less than half a year, there are often failures. Although it is a free warranty, the risk caused is immeasurable, and the personnel resources are also wasted. The corresponding cost performance is greatly reduced.

Factor 3: External Interference

If external interference is not considered, it is relatively easy to simply shield, as long as the shielding power is increased. However, it is necessary to ensure that the shielded area has no blind spots and leaks. The power intensity in the shielded area is relatively large. If there is a little leakage, it will cause great external interference. This requires that the shielding design should be fully considered and controlled technically to achieve accurate and efficient shielding without external interference.

Factor Four: Cost

The cost should follow the shielding requirements and budget. You can’t blindly choose cheap products, and you can’t think that expensive products are good. In actual selection, word of mouth is very important, and it is necessary to inspect its past cases on the spot, try the shielding effect, and then make a selection.
