Something about the frequency of GPS jammers

GPS jammer is the main role is to prevent GPS tracking device. We were told about how it works in the article “what is misery”. If you are concerned about someone chasing you, you may need a GPS jammer to prevent others from using the GPS tracker to track you.

Before you buy it, there is something you should be aware of about these devices. One of the main issues to check when purchasing a GPS jammer is its frequency of operation. Because GPS tracking devices use a variety of frequency bands, especially the GPS L1 band, but there are other frequencies to use, so you need to know the frequency and choose what you need to set their working frequency. Please note that the frequency of the jammer used must be the same as the frequency used by the GPS tracking device for the jammer to work effectively. There are hundreds of GPS jammers on the market so it should be easy to find a jammer that suits your needs and requirements.

If you don’t know the frequency of these trackers, don’t worry. There are many types of GPS jammers, some of which block a primary GPS L1 frequency, and some may be able to block several at once. Of course, there are many high-end models that can block any tracking frequency (GPS L1 L2 L5, GLONASS, Galileo, Compass, etc.) If you want to be sure you haven’t “followed” these tools are yours Option, and of course these devices can be quite expensive, so you should determine how much money you will be making. Surely the GPS jammer can help you keep GPS tracking.

GPS jammers have different qualities – battery life and the frequency of assistance. The most important is the frequency of device support. Battery life is also an important characteristic, and if you plan to use Jammer for a long time, it should be checked carefully. In general, the battery life of portable jammers cannot be used for a long time on a single charge. If you’ve been wanting to use Jammer for a long time. Desktop jammers are better because they are generally used when loading.

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.

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.

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.

The national low-altitude airspace is gradually opening up, and the application of drones is becoming more and more widespread, but the uncontrollable risks from drones are gradually increasing. In the field of civil aviation, the airport encounters drone interference and causes flight alternates and passenger detention. occur. Since 2017, there have been nearly 40 drone disturbance incidents across the country.

In response to “black flight”, although the country has issued a series of drone supervision systems, there are always some “spoken people” who challenge national authority, threaten public safety and personal privacy, and even endanger national security.

Facing the technical difficulties of countering “low, slow and small” targets, effective control of drones still has to rely on professional drone jammer. Anze’s drone jamming gun solves this pain point for you.

The jamming gun is small in size and light in weight. By interfering with the UAV’s data link and positioning system, it cuts off the communication and navigation between the UAV and the remote control, thereby forcing the UAV to automatically land or drive it away for prevention and control Civil and military drones with counterattack.

Every time a product is delivered, we will repeatedly debug. We use our dedicated attitude and professional technology to provide customers with perfect solutions for drone attacks and customized low-altitude support services.

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.

What are the advantages of installing a mobile phone signal jammer in an auditorium?

The rapid development of mobile communication has brought great convenience to people’s work and life, but the side effects caused by mobile phones have become increasingly apparent. The unsafe factors of mobile phones are mainly reflected in the fact that in important secret-related places such as agencies, factories, enterprises and institutions, intentionally or unintentionally dialing a mobile phone or forgetting to turn it off may cause a leak at any time. In some important secret-related occasions or meetings, the use of mobile phones is prohibited. At this time, we will use the cell phone jammer, which is a green new information security product that is newly developed using modern high-tech. The principle is similar to that of the communication signal source. A fan-shaped shielded space is customized according to the power of the jammer, and the normal wireless connection between the signal source and the mobile phone is cut off, so that the mobile phone in this space cannot be received or called. To achieve the purpose of compulsory banning of mobile phones, so as to ensure the safety and confidentiality of the scene. The appearance of the equipment is simple and elegant, solemn and beautiful; efficient and intelligent cooling and heat dissipation system, stable performance, safe and reliable; built-in professional directional antenna, without external antenna, can be directly powered on by the mains; good electromagnetic compatibility, integrated design and installation of the whole machine Convenient and simple to use and manage.

Long-term uninterrupted work: The equipment adopts high-quality components, metal casing, and good heat dissipation performance. It can work uninterrupted for 7×24 hours. Long-term work will not cause damage to the performance of the equipment.

Drones are causing trouble again

From 6 am to 6:30 am local time on May 14, Saudi Aramco’s pumping stations 8 and 9 were attacked by drones, and the company was forced to temporarily close the east-west pipelines. The Yanbu Port that was attacked this time was even more than 700 kilometers away from the Houthi armed forces’ control area, and the ASEF-1 small drones currently in the hands of the Houthi are simply not enough to support such a distance. Voyage. The only explanation is that the attack was caused by a Houthi-armed drone attack squad that penetrated the border between Yemen and Saudi Arabia and carried out a long-distance attack.

Affected by this incident, international oil prices rose sharply during the intraday session, and the intraday increase once exceeded 1.5%.

In March of this year, the Houthi UAV has publicly reached an important strategic goal in southern Saudi Arabia: Suqa Phase 2 of independent desalination and power plants. Compared with the last reconnaissance operation on Suqa Plant 2, the attack on Yanbu is even more shocking, which is too far away from Yemen. Yanbu is located in the central area of Saudi Arabia’s Red Sea coast. The closest distance to Yemen is more than 800 kilometers. The range of small drones in the hands of Husseis is not that far. For such a long-distance flight, at least a medium-sized drone of the level of Rainbow 3 is required. The flying distance has exceeded the direct communication distance between air and ground. Satellite relay communication equipment is required to ensure the communication between the drone and the ground station. Because of the Houthi armed forces’ equipment level and organizational capabilities, the take-off point for this attack cannot be in Yemen. Either take off from the sea, or secretly infiltrate and take off near Yanbu. Obviously the former is the least difficult to implement.

The seven UAVs used in the attack were QASEF-1 suicide UAVs in the hands of Hu Sai. The pictures and information of the aircraft that Hu Sai has shown to the outside world are based on Iran’s Ababil-2 UAV. The maximum flight distance can reach 150 kilometers, the length is 2.5 meters, and the wingspan is 3 meters. Small fishing boats can carry it. . It is very likely that the fishing boat controlled by Husai sailed concealedly to the sea off Yanbu Port. The 150-kilometer voyage can ensure that the ship is on the high seas. The total weight of the warhead carried by the 7 QASEF-1s is 210 kg, which is enough. Two carefully selected pumping stations caused serious damage.

This shows the touching degree of the combat power of the Saudi “Royal Army”. First of all, the borders of their homes were infiltrated by the armed men of the other side without even knowing it, and they were allowed to run hundreds of kilometers in their own territory. What’s more, Iran’s aid to the Houthi armed forces has been significantly reduced after the sanctions. This can be said to be a wave of high-profile UAV counterattacks by the Houthi armed forces against Saudi Arabia under desperate conditions. Saudi Arabia, whose annual military expenditure is as high as 67.6 billion U.S. dollars, has nothing to do with it!

It’s time to consider using drone jammer to counter drone.

Why drones become a nightmare at British airports

London’s Gatwick Airport (Gatwick Airport) has been closed for more than one day under the influence of drones, affecting more than 700 flights and affecting approximately 100,000 passengers. The local police have yet to find anyone operating the drone, but they suspect that it may be the work of environmentalists.

A Gatwick Airport spokesperson pointed out that the British police and military have provided additional precautions for the airport to allow the airport to reopen and allow aircraft to take off.

Many drones are now cheap, and you can buy them for as little as tens of dollars. But the BBC science and technology reporter Jane Wakefield (Jane Wakefield) reported that these small aircraft can have a huge impact on civil aviation traffic.

What is the impact of drones on aviation safety?

A UAV collided with a civil airliner at an airport in Canada in October 2017. The wing was slightly damaged, but it still landed safely afterwards.

We are not yet fully aware of the consequences of a collision between a UAV and a civil airliner. Many organizations have done relevant research to simulate the consequences of collisions between drones and passenger planes in different situations, but the conclusions of each test seem to be different.

The University of Dayton in the United States simulated a collision between a one-kilogram drone and a civil aircraft flying at 383 kilometers per hour. The results showed that the passenger aircraft was seriously damaged.

If there is a drone jammer gun, will the situation be better?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type. The principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range. The operating distance is within 1000 meters, which can force the long-distance low-altitude drone to fall, return to the operator or descend smoothly in a short time, thereby realizing effective control of flying drones in the “control area”.

6 ways to prevent decoder theft

When the car owner locks the car, it intercepts the decoded signal sent from the car’s key to the car’s central control lock device, analyzes the frequency and data in it, and copies this signal to control the car door lock and easily steal the owner’s car or car property.

The car GPS jammer has a low technical content. The principle is to send out a frequency similar to the original car key signal, and the signal is strong, covering the original car key signal, making the vehicle unable to lock the door, and taking the opportunity to steal the property or the vehicle after the owner goes away .

car gps anti track blocker

“This kind of device is a decoder, rather than a codecutter, because it mainly relies on intercepting the signal to copy the signal.” Master Su said, the public need not be too panic, because only when the owner of the car is opening or locking the car, it is illegal. Only the disciples can take advantage of it. However, in order to avoid property damage, Master Su reminded the majority of car owners to be more careful when parking.

Learn the following 6 tips to reduce the chance of theft of vehicles and their belongings:

1. When you lock the car, pay attention to whether there are suspicious persons within 10 meters.
2. When locking the car, the owner should not be too far away from the car to reduce the range of sensor sensing by the decoder.
3. When using the car anti-theft alarm, install a mechanical anti-theft device and install several concealed locks, such as steering wheel locks and gear locks, so you are not afraid of any decoder.
4. Look for a more side-by-side anti-theft method, do not install the anti-theft device in a fixed position, which increases the time of the thief’s crime, and the thief will lose patience, thereby reducing the chance of successful theft.
5. Load the GPS global positioning system on the car. Even if the car is stolen, the police can quickly locate the stolen vehicle and retrieve the stolen vehicle as soon as possible.
6. It is still necessary to emphasize that you should not put valuables such as leather bags, mobile phones, cash, etc. in the car to avoid losses caused by criminals.

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.
