4 major factors that affect the cost-effectiveness of cell phone signal jammer equipment
The first factor: high shielding efficiency.
The so-called shielding efficiency refers to whether the shielding effect has blind spots or leaks. Near some schools, there may be a mobile phone transmitting base station with a strong signal. In order to achieve a good shielding effect, a lot of materials and energy are needed, and the corresponding cost will also increase greatly. Therefore, the better the shielding, the higher the cost. In practical applications, the cell phone jammers of campuses are generally higher, and there are slight loopholes and blind spots. Violators may seize this loophole, allowing mobile phones to be used in the originally specified shielding areas, failing to achieve the original intention of shielding mobile phones.
The second factor: interference.
If there is no need to consider external interference, single shielding will be relatively easy, as long as the shielding output power is enhanced. However, it is necessary to ensure that there are no blind spots or leakage points in the shielding area. The output power intensity in the shielding area is relatively large. If there is a little leakage, the external interference will be relatively large. These require full consideration in shielding design and technical mastery to achieve accurate and efficient shielding without external interference.
The third factor: uptime.
If the original trouble-free service life is 1 year, and the actual trouble-free life reaches 3 years, the cost-effectiveness will be tripled.
For example, the originally stipulated trouble-free life is one year, but in actual use, failures often occur within half a year. Although the warranty is free, the risks caused are immeasurable, human resources are wasted, and the corresponding cost performance is greatly reduced. The fourth factor: cost.
The cost must keep up with the signal blocker and budget. You cannot blindly choose cheap products, and you cannot think that expensive products are good. In actual selection, reputation is very important, and you must also examine its past cases and test the effects yourself before making your selection.
