Nowadays, there are more and more advantages brought by mobile phone signals, but some limitations will inevitably appear. For some occasions, mobile phone signals are completely unnecessary or cause a lot of interference. Therefore, a cell phone jammer is used, so that there will be no cell phone signal where it is installed. What factors affect the cost-effectiveness of the shield?
One: Effective shielding range
The effective shielding range is whether there are blind spots or leaks within the shielding range. In some places where a mobile phone signal shielding device needs to be installed, there may be a base station of the operator, so the mobile phone signal in the place will be very strong. In order to achieve a good shielding effect, it takes a lot of materials and energy, and the cost is corresponding. will increase substantially. Therefore, the better the shielding effect, the higher the cost will be. In practice, the shielding requirements of 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 originally stipulated shielding area, and the original intention of shielding the mobile phone cannot be achieved.
Two: No downtime
Assuming that the fault-free service life of the cell phone jammer is 1 year, and the actual use of the fault-free device reaches 3 years, then the cost performance is 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 free of charge, the risk caused is immeasurable, the personnel resources are also wasted, and the corresponding cost-effectiveness is reduced.
Three: external interference
Regardless of the external interference of the mobile phone signal shielding device, simple shielding will be relatively easy, as long as the shielding power is increased. However, it is necessary to ensure that there are no blind spots and leaks in the shielded area. The power intensity in the shielded area is relatively large, which may cause great interference to the outside world. This requires that the shielding design should be fully considered and controlled technically to achieve accurate and efficient shielding without external interference.
Four: cost
The cost should follow the shielding requirements and budget. You can't blindly choose cheap products, and you can't simply think that the higher the price, the better the shielding effect. In the actual selection, the shielding effect of the mobile phone signal jammer is very important. Shield effect, then make a selection.
