Mobile phone blocker is a mobile phone blocking program or mobile phone detection system, designed to prevent unauthorized mobile phones while allowing authorized mobile phones to run. Blocking cell phone signals can prevent certain critical foundations, unauthorized calls to courts, military installations, or certain environments that need to manage cell phone activity to control the control.

Please note that in some states, cell phone jammers are illegal. Although attention to information rejection has long been an integral part of the PLA’s doctrine, this jammer is mainly used in military locations or other places where the use of mobile phones is prohibited.

Truth|Does the cell phone signal jammer affect the human body?

Generally, people have inexplicable rejection of wireless devices. They always think that the signals emitted by wireless electronic products will affect their health. So, today, let’s talk about whether cell phone signal jammers have any impact on human health.

First of all, concerns about radiation from electronic products have always been a controversial issue among the people. Because we know that all electronic products have radiation, but different products have different amounts of radiation. Generally, the equipment of regular cell phone jammer will be monitored by the National Center for Disease Control and Prevention before leaving the factory. At present, the National Standards of the People’s Republic of China “Electromagnetic Radiation Protection Regulations” (GB8702-88) and the People’s Republic of China Environmental Radio Wave Hygiene Standards (GB9175-88), according to the national standard radiation level requirements, are allowed only after manufacturers who produce electronic products have passed the test. sell. And after installation on site, it also needs to undergo radiation testing by the National Center for Disease Control and Prevention. For engineering sites that meet national standards, the National Center for Disease Control and Prevention will issue an electromagnetic radiation testing report.

After testing, electronic products that meet the national standard radiation level requirements have no effect on the human body, so there is no need to worry about whether the signal radiation of the mobile phone signal jammer will affect the health of the body. In addition, according to the conversion of relevant data, the amount of radiation from the mobile phone to the human body should be the largest, and the radiation from the shield to the human body is almost negligible compared with the radiation of the mobile phone we use daily.

Do we really need to install a cell phone signal amplifier?

We can often see mobile phone signal amplifiers installed in many places such as tall buildings, basements, shopping malls, restaurants, karaoke saunas and massages, underground civil air defense projects, subway stations and many other places to solve these signal blind areas and weak areas. Poor problem. But do we really need to install a cell phone signal amplifier?

cheap portable wifi signal jammer

1. With the rapid development of my country’s economy, the requirements for mobile communication services are getting higher and higher. The rapid development of mobile communication and the rapid increase of mobile users have resulted in smaller and smaller cellular plans and smaller and smaller coverage areas of mobile phones.

2. With the rapid development of the city, the planned use area of ​​the city is getting smaller and smaller, and the tall buildings in the city are being built higher and higher. The signal base stations on the back of these tall buildings or underground are blocked by the high-rise buildings, and the signal attenuation is serious. The mobile signal received by the mobile phone also weakens.

3. With the rapid development and renewal of the city, the decoration level of the exterior of the building has also improved. The commonly used metal steel structure, aluminum alloy structure, etc. absorb and reflect the signal, making the mobile phone users in the building unable to normally accept the outdoor Cell phone signal

4. Due to the blocking and reflection of electromagnetic wave signals by buildings, some places in closed buildings, such as shopping malls, supermarkets, KTVs, bars, underground parking lots, etc., cannot actually receive external mobile phone signals normally.

In view of the above four points, in order to make normal communication between mobile phones, normal calls and Internet access, we need to install a set of mobile phone signal amplification equipment to amplify the normal signal from the outside of the mobile phone to the place we need, and give it to the inside Staff or customer personnel bring the convenience of mobile phones.

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.

Jammer-mart successfully completed the delivery of the UAV defense system at Zhangjiajie Hehua Airport!

On November 24th, our company tested the UAV defense system-portable for Zhangjiajie Hehua Airport and completed the delivery.

UAV jamming system contributes to national defense

In the Zhurihe military parade in Inner Mongolia on July 30, 2017, there was a modern information warfare unit, which was responsible for ensuring the communication of the unit. Drone jammer is another important part of modern information operations. Among them, the second-generation individual portable anti-UAV equipment is an anti-UAV information individual operation equipment.

uav drone blocker

This single-soldier drone jamming device interferes with the drone’s sensors and flight control signals to force the drone to land or return, without destroying the drone. The UAV jamming system of the device looks like a rifle, and it is easy to operate and can be operated by one person. It can block the signal between the interfered drone and the remote control by transmitting wifi and GNSS signals. When the jamming system is turned on, it will completely cut off the connection between the drone and the ground workstation, thereby ensuring airspace safety and interfering with illegal drone intrusion.

Military heavy ground needs UAV countermeasure system defense

With the development of science and technology, drones have become more and more common. They are not only used in the military, but also in civilians. Moreover, drones are widely used. They have night-time camera functions and can quietly disappear at night. Flight at various places. People can use it to take pictures, to video, to explore, to peep, etc. It depends on what kind of behavior the drone owner will have. If it is a military powerhouse, drone countermeasures systems are needed for defense.

Since drones are more common and common, if a military site is peeped or attacked by drones, it will bring serious consequences. Because the drone has an intelligent form, it can also be controlled. As long as the operator connects to the computer, he can see everything the drone sees through the computer, and some can also launch an attack. There are many military secrets in military powerhouses. Once snooped by drones, it often leads to the leakage of military secrets.

If there is a drone jammer in a military powerhouse, once the UAV enters, the surveillance system can be used for monitoring and the UAV can also be landed. Destroying devices can also be used, but generally as long as the drone is knocked down, it can be studied through the drone to know the main messenger behind the scenes.

What are the basic advantages of drone jammers

After the development of UAV monitoring equipment, its application has become more and more extensive, especially in many high-tech fields, and its role is still very good. Therefore, the design effect and function of the UAV jammer will be even more different. So what are its basic advantages?

drone jammer gun high power

The use of radio and photoelectric technology makes the system technology of the drone jammer interfere with the signal during the use process is relatively advanced, especially in the recognition and judgment are very accurate, after the signal is identified, the interference will be carried out immediately , It will not affect its operation. Therefore, it is getting higher and higher in its technical level, which has been recognized and trusted by customers. From a design point of view, you all think that the functional characteristics of drones will be more diversified. In the analysis, you all feel that the functional advantages of jammers are diversified, and the role played out is quite good.

After comprehensively analyzing and summarizing the diversified UAV jammer design, it will always reach the level of system technology, and it has been recognized and trusted by customers during the application process. Therefore, the principle of action in the interference process is still more and more advanced. From the perspective of promotion, they all feel that its performance advantages are diversified, and the choices it brings are worthy of recognition. Sales advantages have been trusted and recognized by customers. After mastering the basic points of its jammer, it can be seen from the design that its performance will be more prominent, and the choices brought are diversified.

China’s self-developed UAV jammer looks strange like a chainsaw

The first is discovery. Almost all current large-scale advanced drones use stealth design, which makes it difficult to discover their whereabouts. At this time, the long-wave radar is used. The current stealth drones are mainly effective for centimeter-wave radars, but for long-wave radars, drones are almost impossible to stealth. Long-wave radar can provide early warning and azimuth indication for stealth drones, laying the foundation for subsequent strategy development.

The second is interference. Utilizing ultra-high-power drone jammer to transmit strong electronic waves to the UAV, blinding the UAV’s radar, cutting off the “umbilical cord” connection between the UAV and the space-based satellite and parent base, making it unable to receive remote control instruction. * Is to take over. When the UAV’s accusation command is interfered by strong electronic waves, it will retransmit a fake GPS parameter to the UAV to make it fly according to the path desired by the trapper, and finally control it to land smoothly to the designated location.

drone jammer gun high power

However, the theory is so, but in fact, because the enemy UAV also has information encryption and anti-interference methods, it is not easy to operate. All military powers are sparing no effort to develop technologies that can “trap” drones. For example, Russia’s “automobile field” is one of the few electronic countermeasure systems that can “trap” advanced drones. It consists of dozens of vehicles, loaded with radar, electronic jamming equipment, and ground command equipment, which can easily penetrate The enemy’s electronic jamming waves and avionics resistance.
