From ancient times to today, security has always been an important aspect, such as military, network and many other fields. In this case, we need to use different types of security tools in different areas, such as WiFi jammers, which can protect the network security.

In order to ensure a safe environment, various safety measures have been taken in different locations and regions. For example, in factories, hotels, schools, and many other places, we can usually see that in many places, maintenance personnel of buildings should register first. All of this is to ensure security. We can see that security plays an important role in different regions and networks. Now, more and more people are accepting wireless network jammer devices.

How effective is the shielding of household signal jammers?

The mobile phone signal shielding system is a relatively professional modern communication signal shielding technology, especially in the special environment of prisons, which puts forward higher requirements on the mobile phone signal shielding technology. For example, in the application environment of the communication signal shielding system of a general meeting, participants come and walk in a hurry, and there is almost no time to “search” for the blind spots of communication signal shielding. In the special environment of the prison, the number of people is dense and the activities are more concentrated. This is the time to use mobile phone signal jammer for shielding.

1. How to evaluate the effect of the cell phone signal shielding system in the prison? If there is no shielding blind spot in the prison, the test should be repeated. In places with strong signals, such as “windows” or “every corners”, professional equipment detectors should be used. , Radiation, and shielding of other systems; to achieve no blind spots; to comply with the inspection regulations of relevant departments

2. The shielding effect and external shielding?

The high-quality mobile phone signal shielding system project must be completely shielded without affecting the communication of residents, not letting people complain, not allowing mobile and China Unicom to cause trouble, and the shielding area is more accurate, and there is no shielding outside the shielding area, which can be regarded as a complete acceptance project.

3. Problems with upgrading and expansion? The wireless communication technology is developing rapidly. 5G is currently in the trial operation stage. Yesterday, the system could be completely shielded, and there may be problems today. Therefore, the construction of the shielding system should be modularized, and it can be easily upgraded according to the changes of the surrounding communication facilities, so as to substantially save the project investment and achieve permanent shielding.

Factor 1: the effective shielding of mobile phone signal jammer

The efficiency of the so-called cell phone jammer is whether the shielding effect has blind spots or leaks. Near some prisons, there may be sources of strong mobile phone signals. In order to achieve a good shielding effect, a lot of materials and energy will be spent correspondingly, and the cost will correspondingly increase substantially. Therefore, the better the shielding effect, the cost will increase accordingly. In actual use, the shielding requirements of the prison area are generally higher, with a little leakage and blind spots. Some personnel may seize this loophole, so that the mobile phone can be used in the originally prescribed shielding area, which cannot achieve the original intention of shielding the mobile phone.

Factor 2: No malfunction time of mobile phone signal jammer

If the original stipulation that the failure-free service life is 1 year and the failure-free service reaches 3 years in actual use, the cost performance will be tripled. If the original stipulation that the failure-free service life is 1 year, it will often fail in less than half a year in actual use. Although it is a free warranty, the risk is immeasurable, personnel resources are wasted, and the corresponding cost performance is greatly reduced.

Factor three: external shielding of mobile phone signal jammer

If external shielding is not considered, it is relatively easy to simply shield the mobile phone signal, as long as the shielding power is increased. But it is necessary to ensure that the shielding area has no blind areas and no leakage points. The power intensity in the shielding area is relatively large. If there is a little leakage, the external shielding will be large. This requires full consideration and technical control during shielding design to achieve precise and efficient shielding without external coverage.

Factor 4: Cell phone signal jammer cost

The cost should follow the shielding requirements and budget. You can’t blindly choose cheap machines, and you can’t think that expensive is good. In actual choices, word-of-mouth is very important. It is more necessary to investigate past cases on the spot, test the shielding effect, and then make selections.

Explain the function of GPS jammer

When purchasing and using vehicle mortgages, it is best to configure GPS jammer within a certain stage. Especially some car dealers who hand over the car and purchase the mortgaged car, in other words, once they receive the car, they can turn on the GPS jammer and put one in the car, and one in the car trunk! When the shield is turned on, you can be assured of peace of mind when you take the car back and forth. However, the jammer cannot be activated 24 hours a day, so after the safety reaches its own chassis, you must find a technical professional to investigate the GPS by yourself, and modify the GPS positioning equipment and mortise locks, key changes and other security guards to prevent mistakes. just in case.

gps signal blockers

1. Understand the GPS jammer
GPS jammers (jammers) can reasonably prevent being tracked by GPS communication satellites, reasonably affect GPS communication satellite signals, and maintain your track privacy protection and information business secrets.

2. The function of GPS jammer
The GPS signal is the same as the signal on the mobile phone, it is very susceptible to the influence of electronic components. The signal jammer can shield all the signals in a certain range, so that all communication devices in the range lose the signal. The installation of a GPS locator on the car enables buyers to easily find their own car on the GPS monitoring management platform. As everyone knows, such a good product is also found by criminals to find loopholes. If you buy a signal blocker on Taobao, Turn on when the car is stolen, there will be no signal in the car, and the car will go offline on the service platform, as if the whereabouts of the car are unknown, you can’t find it anyway.

3. Disadvantages of GPS locator
I have to admit that the GPS jammer also has disadvantages for the user. The signal jammer is only temporarily turned on, and it is unlikely to be turned on all the time. If he turns off the jammer, the GPS locator will have a signal again. Drivers can quickly find the stolen car based on precise positioning information.

In addition to signal jammer, some people will say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also an objective fact, but this is only valid for some GPS devices. If the GPS tracker is in a dormant state most of the time, the signal detector will not be able to detect it! what happened?

For example, some ultra-long standby GPS locators can only be awakened once a day. After being awakened, the precise positioning information of the vehicle is sent back to the buyer’s network platform and then it enters the dormant state. In the dormant state, it is Without a signal, it is absolutely impossible for car thieves to detect it! In addition, it is also free of wireless network installation. There is no wiring on the surface of the machine and equipment. It can be placed anywhere on the car (if it does not have to be placed in an area blocked by the signal). It is very concealed for engineering safety.

We have solved the four major methods of cracking the signal jammer

Four ways to crack the school signal shielding! Don’t worry about exams

First declare that our company has completely solved this problem!

Method 1: Number segment cracking method

The school uses an older signal jammer that can only shield the old number segments of PHS, China Mobile, and China Unicom, such as the new Telecom Tianyi 186, China Unicom’s Wo number segment and China Mobile’s TD-SCDMA etc. number segment. of! Simply put, the China Unicom and China Mobile numbers beginning with 13 15 and all PHS numbers can be blocked! The beginning of 18 will not be blocked!

Method 2: Band cracking method

Because the school’s cell phone jammer works to shield the mobile phone by interfering with the mobile phone signal of the designated band, so long as the mobile phone’s receiving transmission frequency can be modified to prevent it from being shielded, the jammer can only shield the mobile phone signal of 900—1800MHZ, and the mobile phone The receiving and transmitting frequency of 850-1900MHZ is much larger than the shielding range of the jammer, so as long as the receiving and transmitting frequency of the mobile phone is adjusted to the maximum in the mobile phone settings, the mobile phone signal can be received normally.

Method 3: wifi cracking method:

This method has high requirements for mobile phones and the environment, but the effect is the best and most concealed. The premise is that the mobile phone must have wifi wireless Internet access function and there must be an available wireless network around (it is almost impossible in our first high). After searching and successfully connecting to an available wireless network with your mobile phone, you can still surf the Internet even if your mobile phone has no signal and no traffic. At this time, if you want to find the answer you can’t find, you can use Baidu. If you want to send the answer, you can use QQ. Row. A method of hyper perversion.

Method 4 Bluetooth cracking method:

It is suitable for students with a distance of no more than 50 meters to pass answers to each other. It is also possible to test two adjacent classrooms by myself. Install bluetooth software like bluetooth hacker on the mobile phone, and then both sides turn on the bluetooth visibility. In the software option, there is an option to force the message to be sent via bluetooth. Enter the answer and force it to be sent, and all bluetooth mobiles that turn on the visible bluetooth will accept To the answer, one person sends the whole class to share. The above method is a method that I came up with after several days of meditation. It is dedicated to all the students in a high school who are distressed by the signal being blocked. I hope that using the above methods can liberate students from the abnormal school and get relaxed and happy!

Prevent children from indulging in mobile phones-how to choose home mobile phone signal jammer

With the advent of summer vacation, primary and secondary schools all over the country began to have holidays, but the tests for parents have come one after another-what should I do if children are addicted to cell phone chat, what should they do if they don’t have a good rest and play mobile games in the middle of the night, children hold their phones all day and are indifferent to other things How to do? These are the questions I have received the most recently.

When encountering such consultations, I generally recommend parents to communicate with their children so that they can learn to self-discipline. However, some parents also reflect the actual difficulties and hope to purchase home cell phone signal jammer to interfere with/cut off cell phone signals. Yesterday, an older brother hoped that his younger sister could concentrate on studying. He sacrificed the fun of playing with mobile phones and bought a cell phone signal jammer. My heart is still very warm!

handheld signal blocker

Then let’s talk about how to choose a mobile phone signal jammer at home (to prevent students from indulging in mobile phones)?

Shielding range: The shielding range is proportional to the power. For low-power signal jammers, one is enough to install in a room, and the shielding area is about 20 square meters; while for high-power jammers, the shielding distance can reach 100-400 square meters. The local field strength is different or whether you need to go through the wall to decide (some parents will choose to install the mobile phone signal jammer in their own room).

Signal strength: The distance between the surroundings and the signal base station and now many cell buildings have signal base stations or signal amplifiers. According to the shielded frequency band: Before purchasing, you need to know which signals you want to shield. The ordinary mobile phone signal (2345G) can be selectively shielded. If you only shield 2G or only 345G, this can be adjusted before leaving the factory. There are 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands. Here we need to explain the function of each signal frequency band. Simply put, 2G is the frequency band for making phone calls, and 2345G is the frequency band for mobile phones to access the Internet, so it depends on the specific shielding frequency band requirements.

Appearance: The appearance of the mobile phone signal jammer can be divided into an external antenna and an internal antenna. In general, the external antenna is externally installed and stretches out, so it takes up more space than the internal antenna. The volume is larger; because of the antenna extending outward, the effect of the external antenna is more stable.

Power supply: Generally, the power supply of the jamming device is the built-in lithium battery. After the power is used up, the power adapter can be used for charging; the desktop examination room uses 220V voltage power supply, and the car-mounted vehicle generally uses 12-36V voltage power supply.

What does the price of the signal jammer depend on?

The signal jammer of the mobile phone is rarely used. The places that are often used may only be companies engaged in scientific research. There is also a research and development department on state secrets. The other is the military, where security and confidentiality related areas have set up cell phone signal blockers. It is better to have JAMMER-MART among the signal jammers in your hand. The brand Shenzhou Mingda is also sold at different prices. That’s because their performance is different. Let us look at the price of cell phone signal jammers.

indoor phone jammer

1. Cell phone signal shielding looks at the price from the power level
The mobile phone signal jammer has its own capabilities. Generally, the greater the power, the greater the range of cell phone signals that can be shielded, and the lower the power, the smaller the range of cell phone signals that can be shielded. Therefore, the price of mobile phone signal converters is also related to power.

2. The price of the signal jammer on the mobile phone is determined according to the main purpose.

We are also very aware of a problem, that is, the price of mobile phone signal jammers is determined according to the purpose. For example, if you buy a school with 5,000 students at a lower price, it is absolutely impossible, because the purpose of shielding cell phone signals is impossible. For example, if you buy an expensive cell phone signal blocker in a small meeting room or a small movie hall, this is not necessary. Because of the small area, we can buy a cell phone with lower power to block the cell phone signal. So according to your own use, decide what type of cell phone signal jammer to buy.

Does cell phone signal jammer affect pregnant women?

1. The signal jammer is aimed at mobile transmitters and has no effect on the human body.

jammer signal device Powerful

2. The mobile phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process, which can cause garbled interference in the signal received by the mobile phone. The mobile phone cannot detect the normal microwave signal data sent from the base station. In the range, the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of banning the mobile phone. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.

3. The mobile phone signal jammer only shields the mobile phone signal without affecting other electronic equipment and is harmless to the human body.

4. The radiation of the mobile phone is similar to that of the previous radio. Generally, the mobile phone has relatively large radiation only when making a call. In fact, pregnant women should be fine as long as they pay a little attention. The larger radiation is actually some electrical equipment at home, such as Said induction cooker air conditioner or something

Cell phone signal jammer manufacturers teach you which jammer is good for prison

In today’s information age, the development of communication technology is changing with each passing day. As a unique member of the communication family, mobile communication plays an important role in people’s lives and industrial and agricultural production. Today, let’s talk about prison cell phone signal shields. Secondly, while mobile phones bring great convenience to people’s lives, they also have some problems that cannot be ignored. Due to the wide coverage of mobile communication networks, the emergence of networks in some occasions makes the use of mobile phones cause people trouble. , Even security risks, such as:

(1) Become a new leak channel, posing a threat to the security of confidential information;

(2) Become a new source of noise pollution, disrupting normal work order;

(3) Become a new unsafe factor and bring hidden dangers to the safety production of enterprises;

(4) It has become a new criminal method, which has an impact on social stability. Therefore, in some places, we should be able to artificially destroy or restrict this kind of network to avoid the harm caused by the mobile network. Under this premise, the cell phone jammer in the meeting room came into being. The essence of the mobile phone signal jammer is: electromagnetic interference is applied to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network. But it has no effect on the signal generated by the mobile phone.

cheap signal jammers

In order for the mobile phone signal jammer to effectively interfere with the mobile network, it must be ensured that the signal field strength of the jammer should be much greater than the field strength of the mobile signal BCH in the interference area. Therefore, the same jammer uses different locations and the effective area of interference. The difference is that the local BCH field strength is generally stronger as it is closer to the base station, and the area where the jammer reaches effective interference is smaller. Generally, the interference radius can only reach 0.5-9m; if it is farther from the base station, the BCH field strength is relatively weak. Then the radius of the jammer to achieve effective interference is larger, up to ten to tens of meters. Therefore, the local BCH field strength should be fully considered before using the interference device, and then the location, number and combination of the interference device should be determined according to the size of the interference area.

Obviously, the farther the jammer is from the base station, the weaker the field strength and the larger the interference radius, and vice versa. The jammer will lose its interference ability if it is very close to the base station.

The interference range of the same shielding device used outdoors will be doubled than when used indoors. If the interference range is less than 200m, a shielding device is generally installed, which can be hung on the indoor wall with a distance of 1 to 1.8m on the ground; if it is greater than 200m, generally Two or more units should be installed and placed on the front and back walls; if the interference space is outdoors and greater than 1000m, multiple units should be used, and the honeycomb distribution effect is better.

Since the frequency band used by mobile phones is dedicated, the transmission frequency of the mobile phone signal jammer in the conference room is completely within the working frequency band of mobile phones prescribed by the country, so it has no effect on other electronic equipment such as TVs and radios. At the same time, the mobile phone jammer only interferes with the BCH transmitted by the base station received by the mobile phone, so that the mobile phone cannot establish contact with the base station, so it has no effect on the mobile phone. Furthermore, although the signal field strength it emits is stronger than that of BCH, it is far weaker than the electromagnetic radiation field generated during a mobile phone call. Therefore, it will not cause harm to the human body and can be used for a long time with confidence.

Which cell phone signal jammer works well in prisons? , Texin has compiled three plans for you!

1. TX-100W high power jammer
2. Portable GPS signal jammer TX-S6

Jammers can prevent the transmission of negative emotions

The humming and noise of the phone in public places could cause negative emotions in others, this behavior is outrageous, especially in theaters, cinemas, restaurants, concert halls and speeches, etc. In order to avoid such a loud voice, a local GPS jammer installed at these locations, in particular 2G 3G 4G, GPS, WiFi, Bluetooth, LoJack jammer, is blocked.

adjustable gps jamming device

Speech is important to show whenever speakers hope to achieve their goals through individual performances. No one likes his speech brutally interrupted by some viewers of the phone, then he felt neglected and disrespectful – and sometimes beat your man is not your competitors, but the vandals. You are these attacked vandals, and worse still, the behavior seems to be understood and appreciated … it really starts, becoming a normal trend, it was to make a speech to the public, there is always a chance that they will suddenly drop out of other phones.

Therefore, we recommend that you install phone jammer before speaking. The equipment can be up to 10 meters, must calculate the area of the place, the device if the number of cell phone jammers. 10 antennas are switched to different interference objectives, as we mentioned in the first paragraph, or we can make them all work. This means that almost the phone can ring and work there (cannot receive and receive phone calls and text), you can use the source Wi-Fi signal, data can be transmitted via Bluetooth, no GPS signal and LoJack, no follow-up. In short, no mobile device can run speech, they can focus on performance and avoid interruptions.

In order to avoid loud noises in the voice telephone, you can better use the jammers.
