What can a prison cell phone signal jammer achieve?

If there is no cell phone jammer in the prison

Contraband phones are a terrible problem. They allow prisoners to secretly handle drugs, run illegal businesses and even organize murders, under the supervision of guards and warden. A prison in South Carolina recently discovered 35,000 cell phone calls and text messages in 23 days. This is a very serious problem for prisons.

High Power Mobile signal jammer

The cell phone owned by the prisoner allows him to contact external partners in the crime to coordinate escape plans, thereby creating a life-threatening situation for the agency’s guards and the public. More commonly, reports from correctional facilities indicate that the overwhelming majority of hidden mobile phones were used to harass victims of their crimes, or that a prisoner repeatedly intimidated his victim to persuade the victim to abandon the accusation or change him. Story to instill doubtful testimony.

Many detainees continue to organize illegal drug trade from within the prison walls. Mobile phones are an important means for detainees to keep drug organizations running and tightly controlled. By contacting visitors before they arrive, prisoners can arrange for the transfer of drugs and drug paraphernalia, allowing them to continue the illegal habits of being detained. The family is often harassed by relatives who have been imprisoned, and when the family realizes that their relatives receive better services during detention, they ask for bail.

A prominent issue is the prisoner’s ability to contact witnesses before an upcoming hearing, trial or appeal. By matching the absence or correcting the conflict in the testimony, the defendant can win relief or complete dismissal charges. The frightening concern that the prison considers is the undetected use of cell phones by prisoners in order to warn other prisoners before accidental searches that may confiscate cell phones, knives, drugs, syringes and other prohibited items. Such smuggled goods may cause life-threatening conditions to prison guards and medical staff.

The prison has tried and failed to prevent cell phones from entering the prison. If there is no way to prevent cell phones from entering the prison, prisoners must also be prevented from using cell phones normally inside the prison.

Talk about the 4 advantages of wireless signal jammer

In the last few years, various types of cell phone jammer have emerged in an endless stream. We are dazzled and dizzy. In fact, not all products are suitable for us to apply to ourselves. Some products are public, so they are not suitable. There is a very special jammer used in other fields by us, and it also appears in front of us. Its name is wireless signal jammer. So what are the advantages of this type of product?

When we use a wireless signal jammer, you will find that no matter where we are, as long as we can turn on such a jammer, no one can search for our wireless signal. In other words, home The effect of the product is more obvious than that of common public products. In such an environment, we can always shield all signals easily, but if we use a public shield, then the shielding effect may be unstable The problem, so we need to understand the specific use effect.

What are the advantages of wireless signal jammers? The following editor from Chengdu Saiyue will explain the 4 advantages of Saiyue wireless signal jammer one by one.

1. Wide application
Wireless signal jammer is mainly used in examination rooms, but not limited to examination rooms. They can also be used in prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, Only used in libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries guarding the scene).

2. Strong pertinence
Wireless signal jammers can be mainly used for domestic college entrance examinations, domestic college entrance examinations, adult college entrance examinations, self-study examinations and various colleges and universities examinations, as well as various middle schools, technical secondary schools, vocational high schools, prisons, detention centers, conference rooms, etc. Use mobile phones to cheat, send text messages, Adverse effects caused by communication with outside prisoners, collusion with others, etc.

Three, the shielded signals are diverse
Effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE.

Fourth, model advantages
1. Using high-dispersion aluminum alloy shell, low working temperature, more stable shielding effect.
2. Built-in silent turbo fan, low working noise.
3. Separate power adapter. 12V/24V DC power supply work, convenient for vehicle mobile work.
4. The antenna is externally designed, and one end of the interface is unified to make the appearance more beautiful and decent. It also has an anti-loosening design, and the antenna and the host have a marked working frequency band to facilitate one-to-one correspondence.

A major feature of the wireless signal jammer is that it is easy to carry, because it is relatively small, so when we go out, we can also carry it around, but there are other types of products around us. There are major drawbacks. Because the public products are relatively large in size and heavy in quality, they may consume a lot of manpower, material and financial resources during the carrying process, and sometimes even extremely difficult problems occur. In comparison, the reputation of household products will naturally be more ideal and more convenient.

How smart home products steal your secrets

There is no doubt that the US’s information technology strength is in an absolute leading position in the world. This strength is not only reflected in the number of information technology talents, but also in the ability to research and develop information technology, control of information resources, and influence on the formulation of information technology standards. For example, the world’s largest professional network warfare unit is in the United States; the mainstream operating systems (such as Windows, MacOS, Andriod, etc.) installed and used in the world’s computers and smart terminals are all developed and designed by the United States; the world’s main 13 root domain name servers Ten of them are in the United States…It is no exaggeration to say that the United States has the power to monopolize the world in terms of information technology. Of course, this also includes the power to invade and monitor the world.

In addition to operating systems, smartphones, tablets, web cameras and other software and hardware that are often “visited” by hackers, household products such as routers, set-top boxes, smart cars, and even smart TVs, smart air conditioners, etc. cannot escape the fate of being invaded and monitored by the CIA . Take smart air conditioners as an example. In order to improve the user experience, some manufacturers have installed microphones inside the air conditioners to collect and feedback the noise generated during the operation of the air conditioners, and use this as a basis to improve the process to improve the user experience. The CIA can use its exclusive mining (not publicly disclosed or feedback to related manufacturers) or vulnerabilities that have been disclosed but not patched in time (such as zero-day vulnerabilities) to attack smart air conditioners and ultimately gain control. Once the intrusion is successful, the microphone used to collect the operating noise of the air conditioner becomes an eavesdropper that monitors the sound of the surrounding environment, making it impossible to guard against. For another example, by invading and controlling smart cars, the CIA can tailor “traffic accidents” for some key targets, which are silent and difficult to track down. The most frightening thing is that the malware developed by the CIA can bypass software that uses cryptographic technology to encrypt storage and communication, and directly obtain your communication information. It should be noted that the “bypass” here does not directly crack the data that has been encrypted by the application, but has been monitored and acquired at the beginning of the information collection and entry (not yet encrypted). Of course, if your smart terminal uses point-to-point encrypted communication at all times, the CIA will still be unable to receive the monitored information.

So you still need to know about mobile phone signal jammer, Jammer-mart.com will be your good choice.

Chinese company fined 34.9 million U.S. dollars for selling mobile phone jammers

Phoenix Technology News, May 27, Beijing time, according to foreign media reports, a man in Florida and a Chinese company CTS Technology were formally fined US$48,000 and US$34.9 million by the Federal Communications Commission (FCC), respectively, because of the man. Use signal jammers to prevent drivers from using mobile phones, and CTS Technology sells these devices.

Signal jammer may hinder the work of the emergency response team, thereby hindering public safety, so the use or possession of these devices is illegal.

It is reported that for two years, the man named Jason Humphreys (Jason Humphreys) has been interfering with cell phone signals on Interstate 4 between Seffner and Tampa until 2014 Was caught.

At the time, MetroPCS reported that its signal towers would always be disturbed at certain times of the day, but in fact this is exactly the time Humphries drives to and from get off work every day.

The document shows that the FCC had planned to fine Humphries US$48,000 two years ago, and this week the FCC finally officially confirmed the penalty.

Humphries told the police that he had been using signal jammers in his Toyota vehicles to prevent other drivers from making calls while driving.

The FCC determined that this was an “unauthorized behavior, which used illegal equipment to cause deliberate interference.”

The fine for the Chinese company CTS Technology was much higher, reaching US$34.9 million. The FCC said that for more than two years, CTS Technology has been selling 285 signal jamming devices to American consumers through the company’s official website or third-party platforms, and falsely claimed that some devices have been approved by the FCC.

The FCC said the company sold 10 high power jammer to the committee’s secret investigators. They can interfere with signals such as mobile phones, Bluetooth, radio waves, and GPS, and some interference strength can even reach half a mile.

FCC official Travis LeBlanc said: “In today’s mobile world, cellular networks, GPS and other signal jamming devices will seriously endanger communications, commercial operations and public safety. The promotion or sale of these devices to the public is illegal and will be severely punished.

YX-007, a global all-recording jammer (jammer), was born in Incom!

As the name suggests, the recording muting device is an instrument for shielding recording. In today’s society, information is rapidly developed. The problem of voice information leakage is a difficult problem to solve in the world. People’s normal conversations are recorded silently and reprocessed out of context to become a means of coercion by people with ulterior motives, which involve national security. Important information is illegally recorded and spread, becoming a security hazard!

For this reason, Tianjin Yingxun Technology Co., Ltd. has developed a sound signal jammer product with great concentration. This product can effectively prevent illegal sound collection such as mobile phones, voice recorders, video audio parts, recorders, etc. According to the needs of users, the company has developed several products covering handheld to desktop, meeting the various needs of meeting rooms and individuals.

In addition, the company’s products have obtained authoritative inspections by the National Security and Alarm System Product Quality Supervision and Inspection Center of the Ministry of Public Security and the Ministry of Public Security’s Safety and Police Electronic Product Quality Inspection Center to ensure the quality of the products.

When the YX-007 series recording muting device is recording, the recording muting device will generate random noise signals, which can produce suppressive interference to the voice signal, so that the recording equipment picks up only noise information, and cannot distinguish the voice information. Ensure the security of voice information. Widely used in: leadership offices, confidential meeting rooms, military war rooms, business negotiation rooms and other places that prevent recording.

Where can I sell mobile phone signal jammers?

At present, there are more mobile phone signal jammers on the market. There is no difference between good and bad. Some time ago, I purchased one from Texin Electronics and placed it in the company’s conference room. The effect is very good.

Generally, one meeting room with more than 100 square meters on your side should be enough. If it is 600 square meters, it is better for you to find out.

Everyone knows that mobile phone signals will be shielded during the college entrance examination. So how much do you know about mobile phone signal jammers? Today, the editor of China Security Network will introduce to you the principles, characteristics, and appearance of mobile phone signal jammers. The problem.

indoor phone jammer

Introduction of mobile phone signal jammer

The cell phone jammer effectively shields all mobile phone signals of CDMA (China Telecom), GSM (China Mobile, China Unicom), SCDMA (Netcom Da Lingtong), DCS (1800MHz), PCS (1900MHz), PHS (Telecom PHS) and 3G Used in examination rooms, prisons, courts, conference venues, libraries, theaters, churches, gas stations, gas depots, gas stations, hospitals and other places that require confidentiality, quietness, riot prevention, and interference prevention.

Introduction to the principle of mobile phone signal jammer

The working principle of the mobile phone signal jammer is as follows: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method.

In view of the above communication principle, 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. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.

Features of mobile phone signal jammer

Only shield mobile phone signals, and does not affect the normal operation of other electronic devices
Only shield mobile phone signals in the examination room, no interference to mobile phones outside the examination room, let alone the base station
Only shield the downlink frequency of the transmitting base station without affecting the uplink frequency
Green and environmentally friendly, the electromagnetic field intensity is far lower than the national standard, without any impact on the human body
The operation is simple, the antenna is installed correctly, and it can run automatically after power on

Problems and solutions of mobile phone signal jammer

1. Why is the shielding range different from that described in the manual when the shielding device is working?

Answer: The shielding range of the jammer is related to the strong electromagnetic field at the shielding site and the distance from the communication station. Generally the best is 200 meters away. The manufacturer has tested it under normal conditions, so the shielding range will be slightly different.

2. Will there be radiation when the mobile phone signal is shielded? Is it harmful to the human body?

Answer: Regarding radiation, as long as electronic products are large and small, there will be radiation. Any piece of electrical equipment will have radiation. Just like the mobile phones we usually use, it is inevitable that there will be radiation when leaning against our ears every day. The country has also set a standard for mobile phone radiation, and the radiation generated by our mobile phone signal jammer is much lower than the national standard, and it is not every day. Lean against the ears, so there is almost no harm to the human body.

Multifunctional signal jammer, suitable for different interference purposes

GPS jammer not only provide communication protection. These GPS jammers can point out small problems in the network signal. The GPS jammer keeps the frequency free from any interference. Entrepreneurs and employees are also protected by any intrusive measures used by database crooks. Multifunctional shields set the tone, making all forms of information indispensable, whether it’s personal or business information.

In addition to GPS jammers, there are several other types of jammers, among which the best jammers are very useful for individuals and organizations.

The mini jammer is an excellent mobile phone jammer that can effectively block the signal while on the move. This portable jammer is not expensive. The portable jammer is very important. The jammer will not affect the work of any other electrical or electronic products around it. This feature of the portable jammer makes it easy to use without any restrictions. In addition, the portable shield is easy to carry and easy to carry. Therefore, it is an ideal choice for individuals. Portable jammers are available in different models and sizes.

portable mobile phone jammer

In addition, there is a 4G jammer, which can block all mobile phone signals from anywhere in the world. The 4G jammer is a very efficient and complex device. It is a powerful device that can block signals up to 20 meters long. The 4G jammer can be operated with batteries and adapters. Therefore, 4G jammers can be used indoors and outdoors. In other words, the advantage of this shield is that the installation location can be selected. 4G jammer is a more convenient shielding device.

The shielding distance of the device has a great relationship with the power of the device and the use environment, and several aspects that are helpful to the shielding effect: one is the output power of the device, the other is the working method of the shield, and the third is the use environment (indoor or outdoor). The fourth is to shield the interference intensity of the surrounding environment.

Mobile phone signal jammer

Nowadays, mobile phones are all digital signals, and the anti-interference ability of digital signals is very strong. Generally, the effect of using analog signal technology to interfere with digital signals is poor. Therefore, digital signals must be used to interfere with digital signals. The interference effect is quite different. The jammer using digital jamming signal technology has lower power and higher efficiency than the jammer using analog signal jamming technology.

The synthesis, attenuation, and reflection analysis of indoor mobile phone signals and interference signals is very complicated. Before shielding, the strength and quality of local cell phone signals have a great impact on shielding. Different mobile phones have different effects. Generally, mobile phones with strong ability to receive weak signals may not have good anti-interference effects.

The direction of the base station and the direction of the shielded area of ​​the mobile phone also affect the shielding effect. Generally, the spatial signal strength is about -60 to -70dbm, and the base station can reach about -40dbm within a few hundred meters, and the mobile phone reception strength range is generally between -35 to -95dbm. The higher the signal power of the space mobile phone, the shorter the shielding distance.

The above conclusions are based on the law of radio signal transmission in free space. In reality, there are many obstacles on the ground that affect the transmission of radio waves. The above can only be qualitatively used as a reference, especially indoors. The above law is very different from the actual situation. Therefore, this problem is difficult to calculate accurately at the time, and can only be determined based on the actual situation on site. Precise construction projects must carry out preliminary research and signal testing, and then design specific solutions. In the later period, timely follow-up tests are required, and certain corresponding supplements can be foolproof, that is, to achieve the effect of strict shielding.

How to use high-power test room signal jammer

The test room high power jammer has become an indispensable tool in the test room, escorting the information security of the test room. However, if we do not use the equipment correctly, there will be poor results, or even an exam room accident. The following Texin Electronics as a manufacturer will share the correct use of the test room signal jammer.

smartphone signal blocker

1. The effective shielding range of the test room signal jammer will be different in different use sites. This is closely related to the signal field strength on site. The shielding range of mobile phones of different standards may not be the same at the same site;

2. The factors that affect the shielding range include but are not limited to: distance from the base station, orientation, obstacles, the wall material of the site building, the installation height of the shield, the installation specifications, etc.;

3. Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one-to-one. Before turning on the jammer, ensure that each antenna is connected reliably. It is never allowed to turn on the device without connecting the antenna;

4. The surface temperature of the shield is about 40～50℃ after working for a long time, which is normal. If the surface temperature is too high, please turn off the power and try to contact your local dealer or agent;

5. The normal installation height is 1.8 meters ~ 2.5 meters, try to choose a place where there are no obstacles between the target shielding area. The wall-mounted installation requires the antenna to face up vertically. When placed on a desktop, the antenna can be folded 90 degrees and then up vertically. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna;

6. During use, in order to avoid possible interference with some electronic equipment, try to keep it at least 1 to 2 meters away from the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, etc.

The above are the precautions when using the test room signal jammer introduced by Jammer-mart. I hope it can help everyone.
