The above is how our 5G cell phone signal jammer manufacturer explains to you the four major advantages of signal shielding equipment.
As we all know, with the rapid development of electronic information technology, the technology of wireless wifi networks used by people has also been greatly improved, resulting in many old WiFi signal jammers needing to be replaced with the latest equipment, so a good signal jammer must include many aspects, not only the product has higher performance and stronger quality assurance, but also it has a cost-effective price, after all, there are many choices. In today's market, but users often want to choose the one that best suits their needs. How does a wifi signal jammer block signals, and how to use it?
1. Select the area where the mobile phone signal needs to be cut off, and place the cutter on the table or wall in this area.
2. After assembly, connect the cutter power supply and turn on the power switch.
3. After the device is connected, press and hold the power switch to cut the device to work. At this time, all the mobile phones turned on on the spot are in the network search state and lose the base station signal. All callers cannot establish voice call connections.
The key of wifi signal jammer is to block the use of mobile phones in places where mobile phones are prohibited, such as various examination rooms, universities, gas stations, churches, courts, public libraries, international conference centers (rooms), cinemas, hospitals, government departments, financial institutions, prisons, public security organs, key military sites, etc. According to statistics, the wifi signal jammers on the market can block mobile phone signals 500M meters away from the tower. The shielding radius is adjustable, and the coverage area is more than 30㎡. The wifi signal jammer only blocks mobile phone signals and does not affect other electronic products. Save electromagnetic energy, output power 12W--480W. During operation, the wifi signal jammer transfers to the high-end scanner through the low operating frequency of the wireless channel at a certain speed. This scanning speed can cause error code effects in the mobile phone receiving message format data signal. The mobile phone cannot detect the normal data transmitted from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone mainly manifests itself in the search network, poor cell phone signal, no service system, etc.
Cell phone signal blockers can effectively block cell phone signals in the specified area, but will not affect electronic devices beyond the shielding range. Blockers can effectively block GPS, WIFI, 2G, 3G, 4G, and other signals, and the latest 5G cell phones.

So how to choose a qualified 5G cell phone signal blocker? In fact, you can first choose a good manufacturer, and then choose the equipment. A good manufacturer can also cover after-sales and other issues, and the effect is guaranteed.
5G cell phone signal blocker uses 5 ways to teach you how to choose signal blocking equipment.
First, the appearance is not particularly critical compared to the blocker, just the set structure is different. External antennas can be divided into external antennas and internal antennas. The external antenna occupies a larger space volume than the internal antenna, because the external antenna is connected to the external antenna, bending and stretching outward; the actual effect of the external antenna is more stable, because the wireless antenna extends outward.
Second, the power size of the jammer
The general power range is 3W-480W. Jammers can generally be divided into low power, medium power, and high power. The power is between 3W-100W. It is generally not recommended to use high-power signal jammers, which will seriously affect the base station signal transmission and have a certain degree of radiation source to the body. For tests, colleges, national judicial examinations, etc., it is recommended to strongly recommend some small and medium-power machines.
Third, the size of the power supply system
The handheld is embedded with a lithium-ion battery, and the adapter battery can be used to charge it after the power is used up; the test site of the desktop all-in-one machine uses a 220V working voltage power supply system, and the car-mounted type in the car generally uses a 12-36V working voltage power supply system.
Fourth, the application site
If it is used indoors, the signal blocker suitable for examination rooms, conference rooms, meeting rooms and other areas is generally small power, and the gas station must use explosion-proof and heat-resistant; if it is a wide outdoor area, a high-power signal blocker must be used to achieve the appropriate distance. Especially it is necessary to pass through the wall.
Fifth, the requirements for working frequency
In fact, it is what everyone knows, 2G, 3G4G and 5G: Before purchasing, you must know what data signal you want to block. The general data signal (2345G) can be selectively blocked. If you only block 23G or only block 45G, this can be adjusted before shipment. There are also 2.4GWIFI, 5.8GWIFI and other frequency bands. Generally, ordinary data signals can basically be blocked quickly.
At present, our information technology is becoming more and more powerful, especially the latest 5G information technology, and with its popularization, the wifi away from home has also been upgraded.
