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. In order to ensure the fairness and justice of the college entrance examination, it is necessary to install the latest 5G cell phone signal blocker to effectively prevent candidates from cheating with electronic devices. It can also be used in cells, military, hospitals, offices and other places.
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. But everyone knows that this has also brought great challenges to information security, which means that the old wifi signal jammer cannot block the new 5G signal, so it is necessary to replace the latest wifi signal jammer, so what are the advantages of the new Wifi signal jammer?

FAQs
1. Why do some cell phone signal indicators still have signal indicators when the 5g signal jammer is working?
A: This is just an illusion. In fact, the mobile phone has been unable to communicate at this time. You will find that there is no signal indicator on the signal indicator when you press the key casually.
2. Will the 5g signal jammer affect the normal operation of other electronic products?
A: It is not easy. This is because the electromagnetic wave signal transmitted by the 5g signal jammer is completely within the mobile phone working frequency band specified by the country, which can only have a suppressive effect on mobile phone communication. Moreover, this signal is always in a relatively static state, which will not cause harm to all electronic products.
3. Does the jammer have any harm to the human body and mobile phones?
A: Please rest assured that the electromagnetic induction receiving sensitivity emitted by the Texin Electronics mobile phone signal jammer is relatively weak. After the Guangdong Occupational Safety and Health Inspection, the data test shows that the radiation source standard is far less than the national standard value, and this kind of receiving sensitivity is far from causing harm to the human body. At the same time, the signal jammer only blocks the forward data signal of the mobile phone, so that the mobile phone cannot communicate with the communication base station, so it is impossible to cause other damage to the mobile phone itself.
4. Is there a difference in the effective distance when the jammer is used indoors and outdoors?
Answer: Yes. The effective distance (5-40 meters) of the 8341 Technology Electronics Mobile Phone Signal Jammer generally refers to the indoor distance. In a wide outdoor area, the effective distance of the jammer can reach tens of meters. It should be emphasized that whether it is used indoors or outdoors, the effective effective distance of the jammer is related to the environmental conditions at the time, such as the distance from the communication base station, the location of placement, etc. Therefore, when using the signal jammer, this factor should be taken into account to avoid the formation of a blind spot in the jamming and thus affect the actual effect of the jamming.
5. Does the jammer have the same effect on GSM and CDMA mobile phones? #GSM jammer
Answer: This is a good question. Because the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the effective shielding distance of signal jammers for CDMA mobile phones is lower than that for GSM mobile phones, but the difference is not very large, about 2-4 meters. However, please also pay attention to some particularly important places, and increase the number of indoor signal jammers when necessary to ensure the shielding effect of CDMA mobile phones.

Communication technology is developing faster and faster, and 5G technology has been basically popularized in recent years, but do you know what is the working principle of wireless wifi signal jammer?
The working principle of mobile communication technology is that within a certain frequency range, the transmitting wireless network equipment and the base station communicate through electromagnetic waves, and transmit data and sound at a certain serial port baud rate and modulation method. The normal operation of the mobile phone is to send the working frequency to the base station, but there is a voice call requirement. First, according to the request report, according to the specific situation of the peripheral channel of the terminal, it is allocated to the mobile phone service channel, so that the mobile phone jumps to the service channel to realize voice calls and transmit data. At the same time, wireless communication must ensure sufficient frequency stability in order to better receive and communicate.
According to the above principle, the several major modules of the wireless wifi signal jammer are composed of switching power supply, scanning control module, segmented RF module, amplifier module, transmitting antenna unit and other parts. After the signal jammer's transmitted scanning signal passes through the inverter, it enters the oscillator and is adjusted to the mobile communication working frequency band, and then amplified by the power amplifier circuit and the voltage regulator diode controls the output power. After amplification, the frequency deviation signal is emitted into the air in the form of electromagnetic waves. Because the frequency deviation signal generates error code interference in the mobile phone's received message format signal (increasing the noise signal ratio to the device threshold), the mobile phone cannot receive the normal data transmitted by the base station, so that the mobile phone cannot establish a normal connection with the base station, thereby causing the mobile phone to leave the base station communication network. The mobile phone manifests as the phenomenon of no network signal and no service system, achieving the actual effect of blocking.
The working principle of the wireless wifi signal jammer is to scan the low-frequency working frequency of the channel to the high-frequency at a certain speed during operation. The scanning speed can also generate error code interference in the mobile phone's received message format signal, and 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, achieving the effect of shielding the mobile phone signal, and the mobile phone manifests as the phenomenon of network search, no signal, and no service system.
The interference output power of the wireless wifi signal jammer is certain, and the shielding radius of the unobstructed space is determined by the path loss and the receiving base station signal pulse signal. In order to achieve the interference of the cell phone signal jammer on the mobile network, it is necessary to ensure that the signal field strength emitted by the jammer exceeds the field strength of the mobile signal in the interference area. The closer the interference address is to the base station, the higher the field strength and the lower the effective interference area. On the contrary, the farther the interference address is from the base station, the weaker the field strength and the more effective interference areas.
It is not difficult to see that within a certain signal strength, the interference range depends on the field strength in the interference area. No matter how powerful the wireless wifi signal jammer is, as long as the signal strength is constant, as the distance increases, the interference signal strength will gradually decrease, thereby losing the interference level. The following is a comparison table of distance and path loss. Then the wireless wifi signal jammer derives the channel output power, base station signal pulse signal, and coverage line gain value to determine the theoretical coverage radius with practical value.
With the advent of the information age, cell phones and other communication devices have become a must-carry device for everyone. We use cell phones in almost any occasion, but in some areas, the use of cell phones and other communication devices is strictly prohibited. So we need a device that can effectively block cell phone signals, and then cell phone signal blockers are born. Let's take a look at the functions of cell phone signal blockers.
1. cell phones and other communication devices have become a common means for new criminal suspects, and cell phone signal blockers can help make an indelible contribution to social stability.
Some new criminal suspects use cell phones to cheat in order to take advantage of people, and some extreme organizations and foreign hostile elements are using cell phones to detonate explosive devices... Practice has proved that cell phones have become a means for criminal suspects to commit crimes in some places, bringing adverse harm to social stability.
2. cell phones and other communication devices have gradually become a new unsafe factor, and cell phone signal blockers can reduce the safety hazards of enterprise safety management.
We go to gas stations, gas stations, oil and gas fields, and petrochemical plants to use cell phones, which will also cause fire accidents or explosions, and the adverse effects will be very serious.
3. cell phones have gradually become a source of noise pollution, and cell phone signal blockers can maintain normal office order in the place.
With the increasing popularity of cell phones, the living environment of conference halls, courts, public libraries, schools and other places has not deteriorated. The noise generated by cell phones destroys the quiet and serious atmosphere of such places and seriously affects everyone's normal work implementation.
4. cell phones have gradually become a way of leakage, and cell phone signal blockers can take corresponding security precautions for confidential information.
With the rapid development of scientific and technological progress, the positioning, tracking and monitoring of cell phones have become the most important means of reconnaissance and intelligence sources around the world. Therefore, as long as you bring a cell phone to a confidential place, whether it is used or not, as long as it is in a dormant state, it is very likely to cause leakage, which will bring serious threats to the unit or individual, and even to the ruling party and the country.
