here are rumors that the wifi jammer device cannot block China Telecom and China Unicom numbers during the exam, and some say that the mobile phone will have a signal if it is attached to the wall. Is it true?
I play games every day in the university dormitory, and I don't know how to talk to them, because I am extremely "unsocial" in this matter, and I am afraid of being excluded when there are too many people.
You can see if there are mobile phone signal towers built by China Mobile, China Unicom, and China Telecom within three or four hundred meters of your home because mobile phones need to communicate and surf the Internet normally.
Once the wifi jammer is turned on, the WIFI signal cannot be searched, and it cannot be connected and used normally. Its power is also large and small, and the greater the power.
The main function of the wifi jammer installed in the school is to interfere with the signal received by the mobile phone from the base station, so that the mobile phone cannot make and receive calls.
If the wifi jammer is really installed in the office building, as long as it is in the area where the wifi signal jammer is placed, all mobile phones will not be able to make and receive calls, send and receive text messages, and surf the Internet normally. It is impossible that some mobile phones have busy tones, some mobile phones have noise.
Anti-radiation suits for pregnant women use nano-materials of various components to interfere with the wavelength of the electromagnetic signal wave of the mobile phone to achieve the ablation and shielding effect on the electromagnetic wave.
The wifi jammer cannot prevent sneak shots, because if the sneak shot device is recording, there is no signal transmission, so there is no way to block and interfere. Now there are devices that can detect whether there is a sneak camera in the room.
The standard wifi jammer on the market can block all 2G/3G/4G mobile phone signals and 2.4G WIFI signals, but 5G WIFI signals are usually not within its standard shielding range. This does not mean that 5G WIFI will not be blocked, because buyers will customize it according to the frequency of WIFI.
What you want to express is to only block the signal of this person in the dormitory, so that his mobile phone cannot make calls, right? There is a small wifi jammer, but it is impossible to block the signal of only one person.
It's like this, my roommate scolds the phone like a mentally retarded person every day when he plays games, wants to make a wifi blocker by himself, and then turns on the jammer when he reaches the finals, so happy. All I know is the same-frequency signal interference. I am a student of electronics.
There is a radiation source, and every piece of electrical equipment will have a radiation source. Just like the transfer of mobile phones that everyone usually uses, a radiation source will inevitably appear when you lean against your ear every day. my country has also set up a mobile phone standard for mobile phone radiation sources.
If you want to block the mobile phone signal, it is recommended to buy a wifi jammer product. Although metal can affect the mobile phone signal.
Isn't it illegal for individuals to manufacture and process wifi jammer devices that are not corporate?
In fact, the dormitory you mentioned is crowded with thousands of people using mobile data at the same time, which leads to network congestion and is blocked by walls.
This is because the steel structure in the bathroom wall is denser, like a wifi jammer. Devices like WiFi routers transmit wireless signals.
The working principle of the radio wifi jammer is that within a certain frequency range, the mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method.
I just hope that the wifi signal in the dormitory will be invalid during sleep, the intention is this... not to mention that everyone understands, in order to make the dormitory quieter. Want a convenient and easy-to-implement method.

There are special wifi jammer, you can find a professional manufacturer of jammers online.
The wifi jammer installed in the examination room will not use high power, so the radiation of the wifi signal jammer is basically negligible.
Using a signal amplifier will not be detected by the signal jammer, but because the two devices, the signal amplifier, and the wifi jammer, are two devices with completely opposite functions and opposing functions.
If the school's installation of a wifi jammer does not affect normal communication outside the school, it is generally allowed.
Because iron is a metal that can reflect wireless signals, placing a mobile phone in an iron box is equivalent to a wifi jammer.
The wifi jammer uses its own frequency to interfere with the mobile phone to receive the normal frequency sent by the base station so that the mobile phone mistakenly thinks that the signal sent by the wifi signal jammer is the signal of the base station.
The neighbor's live broadcast late at night will affect the rest. It is recommended that you communicate with him first and tell him that this will affect his normal rest.
The working principle of the wifi jammer is simply that the frequency emitted by the jammer itself interferes with the normal frequency of the mobile phone receiving the router, making the mobile phone unable to connect with the base station, and thus unable to make calls.
The wifi jammer will not affect sleep. The working principle of the wifi signal jammer is to scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process.
Yes, the wifi jammer is a full frequency band, it can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom.
It is recommended to communicate with your roommate and tell him that playing games at night will affect your sleep. If the communication is really ineffective, you can buy a small wifi jammer and only turn it on when you sleep at night.
There are large and small wifi jammer. There are many channels in any frequency band of mobile communication. In professional terms, it is a channel, and a channel can be used as BCH.
If the wifi jammer is installed in an outdoor environment, it must take waterproof and lightning protection measures. Generally, it is recommended to choose a special installation box for the wifi signal jammer.
In the final exam, the school turns on the shielding device, the kind that has been a long time.
It is still recommended to communicate first because after using the wifi jammer, the 2G/3G/4G mobile phone signal will be blocked.
According to your description, the wifi jammer in your school may only block the 3G/4G Internet access function.

You can search for low-power wifi jammer on the Internet. The frequency emitted by the signal jammer itself interferes with the normal frequency of the mobile phone receiving the base station so the mobile phone.
The function of wifi jammer: used to prevent mobile phones from receiving and transmitting signals with base stations, disabling mobile phones in defined and designated regulated areas.
Now is an era of rapid development of the Internet, information explosion, and all kinds of private data can be seen on the Internet.
There is no way to crack the wifi jammer in the exam. Generally, the wifi signal jammers used in exams are relatively powerful and basically can block all 2G 3G 4G signals.
The current wifi jammer is all frequency bands, which can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom, and Telecom.
The working principle of the wifi jammer is that the frequency emitted by the jammer, itself interferes with the normal frequency of the mobile phone receiving the router so that the mobile phone cannot be connected to the router it cannot normally make calls.
The wireless wifi jammer purchased by the customer many years ago can be confirmed by contacting our company, and the original 8 modules can be increased to a maximum of 12 modules so that there is a redundant space for 4 shielding modules to assemble 4G or 5G.
Now the wifi jammer on the market are full-band, it can be all mobile, Unicom and Telecom three operators below the 2G 3G 4G signal and 2.4G WIFI signal and Bluetooth signal all blocked out.
The current online shopping is very convenient, online you can pick a variety of shields without leaving home, now the shields on the market are full-band, it can be all mobile.
The wifi jammer will have no effect on the human body. Signal jammer works by scanning from the low end frequency to the high end of the forward channel at a certain speed during operation.
Yes, now the new technology of the full-band wifi jammer, that is, you can shield 2G + 3G + 4G + WIFI. There are only shielding 2.4G router wifi, not shielding the cell phone signal, which is mainly based on customer demand.
After the wifi jammer is installed in the toilet of the office building, the 4G network can be blocked.
Can a wifi jammer block 5G signals? The answer is of course yes. For the early traditional wifi jammer device, as long as the frequency band of the signal jammer is increased.
Banks generally use wired networks for office work, so they will not be affected by wifi jammer.
For general exams and small meetings, choosing a wifi jammer with 2W-10W transmission power can achieve good results.
The purpose of the wifi jammer is to isolate, and the circuits that are easy to interfere with each other can be considered isolated:
If the child will cry if the mobile phone is confiscated, you can use a wifi jammer, the mobile phone cannot access the Internet, and the child will not be interested in the mobile phone.
Many people don't know the difference between Bluetooth, Wi-Fi, and mobile data, they are all wireless communication technologies. In fact, the main difference between the two is the frequency band.
1. Fixing clip for wifi jammer cover, the product has good elasticity, easy to tin, and is packaged with SMD carrier tape.

According to the communication principle, the wifi jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process.
In order to ensure the shielding effect of the examination room and realize the interference of the wifi jammer to the wireless network.
Commercial drones are sold in a dizzying array of shapes, sizes, features, functions, and prices, ranging from consumer-grade drones in the tens of dollars to military-grade weapon drones in the tens of thousands.
Although the use of drone jammer is generally restricted by law in many countries other than the military, police, and first responders.
The analysis of synthesis, attenuation, and reflection of indoor signals and interference signals is very complicated. Before shielding, the strength of the local space signal and the quality of the wifi jammer has a great impact on shielding.
The shielding distance of the wifi jammer has a great relationship with the power of the device and the use environment. There are several aspects that help the shielding effect: one is the output power of the device.
The interference power of any wifi jammer is fixed, and the protection radius of the unobstructed space is determined by the path attenuation and the signal level of the receiving base station.
Wifi jammer is mainly for all kinds of examinations, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, government, finance, prisons, public security, military and other places where the use of cell phones is prohibited.
Can not. With the advancement of technology, the current wifi jammer has achieved full frequency break coverage, signal bands including 1G-5G signal, as well as WiFi, Bluetooth, all shielded with one key.
As we all know, cell phone signal has a close connection with the signal base station, you are close to the base station, the phone gets a strong signal naturally.
The advantages of choosing the built-in antenna, if the wifi jammer is fixed in the conference room, the anti-destructive ability of the built-in antenna is better than that of the external antenna.
The 5G wifi jammer is the same as the old signal jammer in the past. Regarding lightning protection measures.
Electromagnetic waves from nature are divided into radio self-waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. Interference signals generated by high-voltage electric fields are also a type of electromagnetic wave.
I searched for a wifi jammer on the Internet. In fact, I only need to block the 3G and 4G signals used for Internet access, but the blocker that can block 4G has other signal blocking functions, and it is impossible to be portable in terms of size and power.
Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the effective shielding distance of wifi jammer for CDMA mobile phones is smaller than that of GSM mobile phones.
The effective distance of the wifi jammer (5-40 meters) generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach several tens of meters.
Please rest assured that the strength of the electromagnetic signal emitted by the wifi jammer is very weak. The test data shows that this signal strength is much weaker than the electromagnetic wave signal emitted by the mobile phone, and it is far from harming the human body.
Wireless signal jammer is a new type of product to protect information security. It uses specific electromagnetic signals to form a shielded network in the area that needs to be protected, so that mobile phones cannot receive base station data. Many people do not know its detailed precautions during installation. Regarding the installation of the shield, the following points should be noted:
Accurate? How could radio interference be called “accurate?”What a gps scrambler does is prevent reception of GPS radio signals. It does this by broadcasting noise. This noise extends quite a distance.Blocking any radio signal is illegal in the US, EU and many other places.
Yes, it works. It can effectively prevent the vehicle from being located and tracked on the road. After the effective shielding, the positioning signal disappears, and the vehicle cannot be located and cannot be located, thereby protecting the privacy of the vehicle.
By using orbiting satellites and radio signals, a receiver can determine the precise location of any GPS-enabled device or vehicle. Jamming occurs when a device emits radio signals at the same frequency as the GPS-enabled device. This causes the GPS-enabled device to be unable to determine its position and can prevent it from establishing or maintaining its connection.
gps blocker device can be used for a variety of applications, such as: Hiding, changing or obscuring positioning signals from GPS units. Inhibiting mobile devices from being able to make or receive calls, text messages or emails.
A GPS jammer is a typically small, self-contained, transmitter device used to conceal one's location by sending radio signals with the same frequency as a GPS device. When this occurs, the GPS device is unable to determine its position due to interferenc.
Criminals could use them to hide their whereabouts from law enforcement -- and some experts fear terrorists could use high-powered jammers to disrupt GPS reception on an airplane or in military operations. The gps blocker device pose serious societal risks, and they're unquestionably illegal to buy and use in the United States.
Fact: Any GPS blockers that blocks GPS signals by emitting an interfering with radio frequency signals is illegal and cannot be marketed or operated in the United States, except in the limited context of authorized use by the government.
In another situation, when you buy such a mortgage vehicle from a mortgage vehicle company, you will inevitably worry about the safety after purchasing the vehicle. Will someone install a locator on the vehicle? Will the car be driven away in the middle of the night after the car is parked? Therefore, in order to protect property safety, car buyers will also buy a monopoly GPS signal jammer..

If your GPS jammer is a direct current (dc) device, you need to plug it into a usable power source, and that's it. It can also be used without a built-in battery, such as a car GPS jammer, which needs to be plugged into the car to lighten the cigarette The socket can be used normally.
GSM signal is a kind of mobile phone signal, so GSM jammer belongs to mobile phone jammer. If you only want to block the GSM signal, you only need to select a GSM jammer that will only interfere with the GSM signal of the device, but if you want to block other mobile phone signals in addition to the GSM signal, such as 3G, 4G or even 5G signals , Then I suggest you buy a GSM 3G 4G 5G signal mobile phone jammer.
A high power jammer means that it can interfere with more signal frequency bands and has a wider range of interference. But like other signal jammers, it is not harmful to the human body. It will only help the devices that you want to prevent signal interference, such as mobile phones, and provide you with a good environment.
In recent years, prisons, labor camps, and detention centers across the country have invested funds to build or rebuild cell phone jammer systems. It is hoped that illegal use of mobile phones will be eliminated, mobile phone management in supervision sites will be strengthened, and supervision work will be carried out smoothly.
As we all know, a good signal jammer needs to cover many aspects, not only the product has higher performance and better quality assurance, but it also has an affordable price, after all, there are many choices. Today’s market, but customers often want to choose the one that best suits their needs. This is also to achieve the most cost-effective consideration.
The cell phone jammer emits interference signals like the frequency that the mobile phone takes over. It just hinders the connection between the mobile phone and the base station so that the mobile phone is always in a state of no signal search, and it will never cause harm to the mobile phone!
Whether the test room signal jammer is effective depends on the environment around the test room and whether the quality of the test room signal jammer purchased is good. The test room environment is mainly to see if there are any base stations nearby. If there is a base station, it needs to be equipped with a little more shielding device.
Is there a base station near the school? In the process of construction, we often find that customers tell us that the signal jammer is not effective. 2G3G can be shielded, which means that the call signal can be shielded, but the 4G signal cannot be shielded. In fact, the power of each jammer is different. Generally, the power of 4G1 and 4G2 is about 2W, which means 33db.
Generally, the area of the examination room is less than 100 square meters. The installed cell phone signal jammers are all low-power. Low-power products are only used in open and small areas. And the current test room cell phone jammer technology is very mature, only shielding the downlink , Does not shield the upstream.
The first way is to surf the Internet via mobile phone operator signals. As soon as the shielding device is turned on, the mobile phone cannot receive the operator's signal, which makes it impossible to make calls or text messages. Naturally, the Internet cannot be accessed, and the shielding is effective.
It is understood that GSM jammer on the market can limit cell phone signals to 500 meters away from the launching station. The shielding radius is adjustable, and the coverage area reaches more than 30 square meters. The mobile phone signal shielding device can only shield the mobile phone signal and does not affect other electronic equipment.
The smart functions of mobile phones are now expanding. In addition to basic call and text messaging functions, they also have digital cameras, camcorders, voice recorders, More application functions such as Internet access. Why is it recommended to install cell phone jammer on the factory floor?
Another important factor is obstacles. If it is a metal material, it will be directly blocked; if it is a solid reinforced concrete wall, it will be attenuated by at least 10 times after penetration.
Hand-held cell phone jammer is a kind of signal jammer for mobile phones, because the mobile phone frequency band is also one of the signal frequencies of mobile phone communication, but it has its unique characteristics.
This is the mainstream of scientific and technological development. Therefore, 5G jammer has already appeared in 2020.
