They look around the knowledge and the beauty of the museum, they can well understand the meaning of it all. Great history, magnificent art, and knowledge of the ocean can make someone fall in love. Everything is harmonious, suddenly, annoy the guy took out his cell phone to call out loud, regardless of the feelings of others, to stop what will happen? Fight with him? There is no good choice here if there are cell phone jammers installed there. There is no problem with that. This is the world of interference. Now put the cell phone interrupt kit so that they understand the value of education and secular knowledge.

Story of drone and mobile phone jammer on NHK News

Knowledge of drone and 4G phone jammer week frequency

By Wikipedia’s explanation, FPV (first person view) is called RPV (remote person angle) or video navigation. It is a backpass facility with a built-in wireless camera based on a remote-controlled model airplane or car model, which is a new way of playing the model on the ground while watching the screen. Over the last few years, more and more drones have been used. This type of FPV utilization is most often seen.
The drone is actually a pilot’s eyepiece surveillance, a higher version of the drone incorporates two in-vehicle cameras and a portable jammer 4g in the pilot’s eyepiece. Can be 3D view

Wi-Fi Radio Blocker Let’s learn basic knowledge about week frequency

2.4GHz and 5.8GHz are the two most common frequencies for being connected to terrestrial radio transmitters and UAVs
The 2.4 GHz band is a common radio frequency. Often used to connect to ground-based transmitter axis aircraft and UAVs. If you know more about frequencies, you may know that the 2.4GHz band of unwanted cell phone jammers is also used in wireless computer networks. Therefore, it can be expected that there will be many accidents that lost control of the aircraft in densely populated residential areas with too many radio signals.

Another problem with drones is that they interfere with the vehicle’s navigation system. This is mainly due to the fact that the two transmitters worked together, one transmitting the guided wave number signal to the vehicle and the other transmitting the video signal to the driver.

The 5.8GHz band is used in 4-axis aircraft technology to avoid entanglement of the same frequency band with other RFs. This week frequency is found in the Dow Phantom model. Let’s see how UAVs work around wireless frequency issues

Phantom 1 This drone works in the 2.4GHz band. If you plan to participate in FPV, you will have to do it yourself using the 5.8 GHz frequency of the mobile deterrent jammer to avoid common problems.

If you use GOPRO or any other action camera’s unique wireless system, remember that the wireless option is turned off. Otherwise, it can interfere with the aircraft. The Phantom FC40 drone has adopted a radio frequency of 5.8 GHz. And since it has a single 3.4GHz system, you can send videos and photos to your pilot.

Phantom 2 Because this drone uses control at a 2.4 GHz radio frequency of a radio signal jammer, you have to use additional tools. Therefore, it transmits the FPV signal using the frequency of 5.8 GHz.

Phantom 2 Vision and Vision+ These two types of drones use 5.8 GHz and 2.4 GHz FPVs separately to take advantage of smartphone application connectivity and telemetry.

Portable jammer final conclusion
Therefore, if you bought a phantom UAV without a camera and other drones, you should use the 5.8 GHz frequency and FPV. By the way, it is worth noting that the RF signal is said to be a LOS mobile jammer or visual signal line. If there is no barrier between the UAV and the remote control, it will show that they cannot work. The best flying area of ​​the drone is directly visible to the naked eye. Otherwise, your drones could be damaged or lost.

Communication function suppression device. Development background and utilization of mobile phone suppression device

While convenience has improved due to the rapid spread of communication devices such as mobile phones and PHS, ringing tones of communication devices and noise caused by telephone calls have become a social problem in spaces such as theaters and halls where a quiet atmosphere is required. I will. In one hall, concerts by prominent conductors have even been interrupted. For this reason, the current situation is that operators such as theaters are strongly demanding the development of effective countermeasure technology.

To prevent ringing tones and calls from mobile phones, PHS, etc.
For this reason, there is a movement to prevent annoyance due to ringing sounds, etc. by using wireless equipment (mobile phone suppression device) that has the function of suppressing ringing sounds and calls from mobile phones.

Contraband in prison: cell phone

Another way for prisoners to evade prison wiretapping is to obtain their own mobile phones. The prison authorities found that prison inmates can easily get their previous mobile phones (which can be activated with a charger). One tip came from the mother of a prisoner who complained in a jail guard at a Texas state jail that her son’s cell phone was not well received.

In addition to known prisoners committing crimes by telephone, the accessibility of mobile phones has become a serious problem in prisons. When members of the prison have mobile phones, gangs can organize themselves more easily. For example, it is reported that in 2006, gang leaders imprisoned in Brazil used their mobile phones to plot a large-scale simultaneous riot, with the purpose of proving their influence and even being locked up in prison. The group caused an uprising in more than 70 prisons. At the same time, members outside the prison caused riots and caused serious damage to public buses and police stations. Gangs have also surpassed American prison cells, where gang leaders can exercise power from inside the prison walls and even order the killing of gangs.

So, how do prisoners use mobile phones? Obviously, it is well known that visitors and corrupt prison guards provide these calls to prisoners. To help eliminate this phenomenon, some states try to combat it by making the consequences more serious. The court allowed penalties for people who were discovered with a mobile phone, because these conversations cannot be monitored and are therefore a security threat. Several states have criminalized the possession of mobile phones by prisoners, while others hope to increase this crime to a felony level.

Desktop high-power jammer

Unfortunately, for prisons, cell phone signal jammer (interfering with radio waves to prevent cell phone communication) from the “prison jamming” system is not a viable option-at least in the United States, because cell phone jamming devices are illegal under property laws. In addition, even if the prison obtains permission to block cell phone signals, jammers may also interrupt the prison’s radio signals. Despite these concerns, prisons in other countries (such as England) have also implemented jammers due to the widespread use of mobile phones.

How to make your own cell phone signal blocker

Cell phone signal jammer is installed in quiet areas, such as schools or universities, but… how exactly does this instrument block cell phones? These locking instruments prevent mobile devices from receiving signals from base stations. While it may sound like a complicated process, making your own phone blocker isn’t that difficult. However, you should know that in many countries (including the United States) they are illegal and subject to large federal fines, in addition to criminal prosecution. Who knows what could interfere …

phone jammers

1. Understand the principles of operation. This cellular signal blocker operates with the GSM800 frequency, since most mobile phones use it to operate. The VCO selected is a sweeping oscillator, which is very effective but can be difficult to build for beginners who do not have good RF testing equipment.
As a noise source you can use a 45MHZ clock oscillator, which is the local oscillator port located on the mini-circuit mixer. There is also an impedance matching network for the local oscillator signal to pass through. It is used to match the impedances of the oscillators and the mixer port.
The RF input (which is the mixer port) connects to the first 800MHz cell antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power by 15-16 dbm. Then the amplified signal is sent to the second antenna of the cell phone.

2. Consider how it works. All cell phones using GSM800 always separate the transmitted and received frequencies at 45MHz. So when the mobile phone tries to call, it is blocked by its own signal coming back to you! Isn’t it cool? So when the chatter of the phone irritates you, turn on the blocker so that the criminal hears his own voice on his cell phone. By the way, you can also use this cell phone signal blocker to block any cell-based tracking system that uses your GPS to track and record the movements of your car. And you can probably block improvised explosive devices that are detonated using cell phones. The mixer that is used is designed to work up to 600 MHz, but in this case it works very well. The RF amplifier does its job quite well even though it consumes additional power.

3 Use an old aluminum box as a frame for the jammer and some old UHF connectors from a Motorola cell phone for input and output.

4 Connect the RF connectors to the circuit.

5 Use a nine-volt battery and a voltage regulator to power all components. Place the battery inside and separate it from the rest of the components using foam rubber.
Flip the on / off switch at the top.

6 Screw the input and output antennas (also from an old Motorola cell phone) to the UHF connectors.

7 Your cell phone blocker is ready. Enjoy it!

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.

How does cell phone signal jammer work!

The current cell phone jammer is full-band. It can shield all the 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under all the three operators of China Mobile, China Unicom and Telecom. Its principle is sent by itself. The frequency interferes with the mobile phone receiving the frequency from the base station and wireless router, so as to achieve the purpose of shielding them. Generally speaking, the working principle of the mobile phone signal jammer is that the frequency emitted by the jammer interferes with the normal frequency of the mobile phone receiving the base station, making the mobile phone unable to connect to the base station, and thus unable to make calls, receive and send text messages and surf the Internet.

mobile signal jammer 5G

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone. 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 and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

No matter what cell phone card you use, as long as the cell phone cards under China Mobile, China Unicom and China Telecom will be blocked. WIFI will also be blocked. Unless you use 5.8G WIFI to surf the Internet, because the standard configuration of the jammer does not shield 5.8G WIFI. However, some schools may let jammer manufacturers order 5.8G frequencies just in case, so this is not guaranteed to be absolutely foolproof.

Whether it is a high power jammer or a small signal shielding instrument, its principle is to interfere with the mobile phone to receive the normal frequency sent by the base station through its own frequency, so that the mobile phone cannot contact the base station, so as to achieve the purpose of shielding. The principle of shielding WIFI is actually that the signal jammer will send out the corresponding frequency when it is working to interfere with the mobile phone to receive the normal frequency sent by the router, so that the mobile phone cannot connect with the router and cannot access the Internet normally.

Mobile phone signal jammers are mainly used in some school examination rooms, dormitories, detention centers, military units and confidential meeting rooms, etc. So as long as you enter these places, your mobile phones will be shielded, and you will not be able to make calls, receive text messages, and access the Internet normally. There is no exception, and nothing can be set to avoid being blocked.

How to use high-power test room signal jammer

The test room signal 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.

wireless network jammer Buy

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. 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 shielding device, 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 high power 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 the 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 to some electronic equipment, try to keep the distance between 1 and 2 meters above the following common equipment: stereo, wireless microphone, radio, computer, TV, Wi-Fi router, etc.

UAV countermeasure market analysis

During this period of time, everyone knows that drone black-flying incidents happen frequently, small enough to be used for peeping, large enough to steal state secrets and military secrets, small enough to fall and injure a person, large enough to cause the airport to close. The delay of the aircraft and the stranded passengers have caused serious consequences. Therefore, the national laws have also been continuously improved during this period. Legal documents have been issued one by one to strengthen the control and real-name registration of drones. Here we do not make any comment on politics, only UAV defense and UAV countermeasures technical means are analyzed.

waterproof drone signal blocker portable

There are several ways to control drones:

1. This method of shooting with a gun seems to be more enjoyable. It not only manages but also destroys it. The damage index is higher than five stars. But there is a problem that is more headache. It requires the shooter to be accurate, not the one who has participated in the Olympics and won the championship. Forget it, so as not to be embarrassed. In addition, you need to find the right time. Once you fall, it is absolutely not allowed to hurt people. It is important to get off the phone. In addition, you must remember where you are calling. If you fall, you need to find it. This is a headache. The question, how many people do you need? Who flew the last question is unknown!

2. Catching with a net is similar to shooting a gun, except that the gun shoots out points, here is the net; it seems that this technology has improved, the destructive power is reduced, and the accuracy rate is improved, but the prerequisite for the problem is The drone needs to fly low, and the human station is high, so the practicability is low;

3. Drone jammer is also the mainstream technology at present. The remote control signal of UAV is blocked by high-power transmission, so that the UAV loses control. Generally, UAVs can be shot down directly, and smart UAVs can also be unmanned. Aircraft interference interferes with GPS and Beidou signals to prevent drones from returning home;

There are two types of UAV interference:

1) Hand-held UAV jammers require humans to conduct investigations, and it is found that manual intervention by the handheld UAV jammers can achieve the control effect; the control distance can generally reach about 2 kilometers;

2), base station type UAV jammer The base station type UAV jammer is mainly aimed at the relatively large control area, prevents the drone from entering the control area, and greatly reduces the safety risk; it can be completed without a large number of personnel operation; control Distance: 6-8 kilometers can be;

In addition, I did a lot of searches on the Internet. The Chinese characteristics are vividly reflected. As long as there is a need for thousands of troops to invest in this market, the market capacity and market opportunities are as big as everyone’s guess;

One set to two sets per unit, let’s calculate that the quantity is really limited and belongs to a niche market; in addition, the technical content is not particularly high, the threshold is low, the more participating businesses, the smaller the market profit margin, so it is recommended that those already on the road should be prepared Don’t be hot on the road for a while, look at the market sensibly.

Jammers can help in the war on terrorism

Terrorist attacks have occurred frequently in recent years and are causing great harm to people. Today, the fight against terrorism has been widely discussed and is one of the things people need to watch out for. We find an important means of the terrorist attacks is a bomb attack that causes great damage as a cruel and common means of the terrorists. Therefore, an important thing to fight a terrorist war is to prevent different types, sizes and powers of bomb devices.

There are many types of bombs. Fortunately, the government also has a special bomb disposal force to deal with these various bombs. However, the most difficult terrorist attacks are not able to tear the bomb apart, but to find and prevent bomb attacks. Can you imagine that when you are on the square, was there a sudden bombing in the cinema? It was too late to prevent it. With regard to the precautionary approach, you know that most of the terrorist attacks are triggered by a simple phone call. At this moment, if there is a suitable signal jammer near the place where the bomb is installed, you can make sure that nothing happens because the signal is not being transmitted. Such cell phone jammers are used by military and law enforcement agencies.

super power signal jammers

In addition, when we refer to the fight against terrorism, we should mention that most countries have started to take these measures and have installed special woes on important roads where the President has witnessed. For this reason, because there is no signal that can trigger a bomb even when it is installed, there is no accidental danger.

The good news is that blocking technology is evolving and its functionality is getting better and better. Some of the best high power jammer can block radio signals in the range of 1 km or more. This achievement is very important because it can be more effective against terrorist attacks.

With the civilian conversion of military jammers and the development of all technology, it is good to know that the authorities are doing their utmost to protect the innocent. The woes can help with the terrorist attacks. The government’s defense measure is all the more important.

Russia has achieved significant results with the GPS jammer

The Russian military buys jammers and plans to install them on cell towers. The idea is simple: the Kremlin can launch these jammers during the conflict and pray that the jammers reduce the precision of the American missile attack.

drone jammer gun high power

Izvestia emphasized that “the system integration in the transmission and reception of communication signals on the tower of the communication tower formed a network that covered the entire area, like a satellite navigation signal through the dome.

The installation of drone jammer on mobile phone towers in Russia is an unconventional step, but its logic is militarily justified. From today’s perspective, the United States has a huge advantage in cruise missiles, drones and GPS systems.

The Russian armed forces are actively trying to block U.S. military drones that fly over Syria and disrupt flight operations by interfering with the signal from the global positioning system (GPS). Jamming has a “serious” impact on US drone operations, but it is not yet clear how serious Russia’s interference is.

According to the report, the jammer was developed by the Russian military and is highly developed to interfere with even navigation devices with anti-jam technology, and is also suitable for encrypted communication, although encryption is difficult for the drone’s control systems to penetrate sensor output. The Department of Defense declined to comment on whether drones had crashed as a result of the disruption.

The use of jamming in situations where the war has not fully emerged would reduce the effectiveness of Russia during a real war as the U.S. and Allied Forces examine the signals and find ways to overcome them and improve it to find fault-resistant system in use. The U.S. Army is already looking for field weapons that do not rely on GPS to get accurate results.

Given the sudden spiral drop of the drone in the published video, the system is most likely to be a radio GPS jammer . Given that the system is being used by the Russian-backed separatists, it is likely that the system will be another electronic war weapon made in Russia that will be used at the front of a proxy war, both for influence on the battlefield as well as for research and testing purposes.

US officials told NBC News that the Russian military had blocked smaller US drones. Jamming focuses on drones’ GPS systems, which can result in operators not knowing where the drone is, for more extreme results such as crashes.
