The choice of 5g signal blocker is mainly based on three aspects: according to the type of signal being shielded, according to the output power size, according to the purchase price, and according to the appearance.
5G signal jammers are mainly used in various examination venues, courts, detention centers, international conference centers (rooms), government departments, the military and other places where it is strictly prohibited to bring mobile phones into people. So how should you choose the most suitable signal jammer according to your own needs? From the manufacturer's point of view, if the selection is unreasonable and the installation has no actual effect, it will easily lead to the return, exchange or refund of the product. Waste time and miss good opportunities! How to choose a jammer that suits your needs without spending transportation fees.
First, the blocked signals can be divided into wireless network signals, Wi-Fi, etc. used by China Mobile, China Unicom, telecommunications networks, radio and television network communication base stations. In addition, there are also 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands. This type of frequency band can be combined according to different needs and can form different types of jammers. Therefore, the first thing to do is to understand the signals you need to block. In the past, the mobile signals that were normally blocked were 2G, 3G, 4G, 5G and 2.4G, but now 5g signal jammers that can block 5g signals have become popular.
Second, the output power size of the shielder: generally divided into small output power, medium output power, and large power. Small output power: total output power 3W-80W. Medium output power has a total output power of 80W-160W, high power: a total output power of 160W-800W. In addition to unique site requirements, it is generally not recommended to use high-power signal jammers, which will seriously interfere with communication base station signal transmission and also cause a certain degree of radiation to the body. For example, in college entrance examination rooms and conference halls, it is recommended to use low-power ones. Even if one low-power one cannot achieve the actual effect in many areas, you can use several multi-tube ones to set up points. In this way, the effect is better than that of using a single power or power in Taichung, Taiwan, and the radiation source is not that large.
Third, compared to the shield, it is not very important. It is just a difference in the structure of the settings. From the appearance, the shield can be divided into external antenna and built-in antenna. The external antenna is because the antenna is external and bends outward. Because of the outwardly extending antenna, the effect of the external antenna is smoother. For machines with external antennas, in addition to the antenna, the external power supply compatibility is also external, so the space occupied by the built-in antenna is larger; generally speaking, the antenna and switching power supply with built-in antenna are installed in the casing Inside, it occupies a small area and is very convenient to use.
What factors must be considered when choosing a mobile phone signal jammer?
When buying a signal jammer, everyone should not only care about the price, but also understand its quality and pay attention to its functionality. So what are the main factors that affect the price of 5g cell phone signal jammers? The reference answer is high shielding efficiency, that is, whether the actual shielding effect has blind spots or leakage. There may be communication base stations with strong mobile signals around some prisons. In order to achieve a good shielding effect, a relatively large amount of material and energy will be spent, and the cost will be correspondingly high. raised dramatically. Therefore, the better the shielding effect, the higher the cost. In actual applications, the shielding regulations in prison areas are generally higher. If there are slight leaks or blind spots, the violators may seize the system loopholes and allow mobile phones to be used in the originally regulated shielding areas. It is impossible to achieve the original intention of shielding the mobile phone.
