If the original stipulated trouble-free service life is 1 year, and the actual use of trouble-free service reaches 3 years, the cost-effectiveness has tripled. If the original non-fault service life is 1 year, it often fails in less than half a year in actual use. Although it is a free warranty, the risk is immeasurable, waste of human resources, and the corresponding cost-effectiveness is greatly reduced. If external interference is not considered, simple shielding is relatively easy, as long as the shielding power is increased. However, it is necessary to ensure that the shielding area has no blind spots and no leakage points. cell phone jammer The power intensity of the shielded area is relatively large. If there is a little leakage, external interference can be great. This requires full design consideration and technical control Project On Cell Phone Blcoker Pdf to achieve accurate and efficient shielding without external interference. Costs should follow shielding requirements and budget. You can't blindly choose cheap products, and you can't think that expensive products are good. In the actual selection, word of mouth is very important. It is also necessary to investigate past cases on-site to test the shielding effect before making a selection.
The shielding distance of the equipment has a lot to do with the power of the equipment and the use environment. Several aspects affect the shielding effect: one is the output power of the equipment, the second is the working method of the shielding, and the third is the use environment (indoor or outdoor). The fourth is the strength of shielding the influence of the surrounding environment. So what does the effective blocking range of Project On Cell Phone Blcoker Pdf depend on? The power of the machine itself. There are many 5W machines on the market now, but the actual power is less than 1W. So it has to be real power. For low-power devices within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember that such a machine cannot go through walls. The density of cell towers near you. Today, many customers buy back their phones. 2G and 3G calls can be blocked, but 4G cannot. what is the reason? This is because there is a base station near you. Generally speaking, there is a base station within 100 meters. If you buy a low-power machine, it is basically impossible, because the signal of the base station is too strong. It is recommended to buy a low-power mobile phone jammer, more than 2W per channel.
