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 price/performance ratio has 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, personnel resources are wasted, and the corresponding price-performance ratio is greatly reduced. If external interference is not considered, it is relatively easy to simply shield, as long as the shielding power is increased. 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 large. If there is a little leakage, the external interference will be great. This requires full consideration and technical control when designing Gsm/Cdma/3G Cell Phone Signal Jammer to achieve precise and efficient shielding without external interference. The cost should follow the shielding requirements and budget. You cannot blindly choose cheap products, and you cannot think that the expensive is good. In the actual choice, word-of-mouth is very important. It is also necessary to investigate the past cases on the spot, test the shielding effect, and then make the selection. cell phone jammer
Nowadays, various signal jammers are common in the market, and everyone’s understanding of Gsm/Cdma/3G Cell Phone Signal Jammer is uneven. What should we know about cell phone jammers? The first point: Everyone thinks that the higher the power of the mobile phone signal jammer, the better the shielding effect. In fact, this is not completely correct. Many manufacturers use some inexperienced users to be unable to detect the loopholes in the actual power, and will deliberately exaggerate the openness of the shielded power, causing the device's nominal power index and affecting its reference value. For large-scale shielding systems,
