From time to time, customers ask us: Does your 5G mobile phone jammer only interfere with the signal of 5G mobile phones? Can other types of mobile phone signals not be interfered? Some customers will additionally ask: Can your 5G mobile phone jammer interfere with GPS satellite navigation signals? Can it interfere with electronic devices such as WIFI routers and Bluetooth headsets?

In fact, the so-called “5G mobile phone jammer” is usually just a general term. After the 5G mobile phone jammer is turned on, it not only interferes with 5G signals, nor does it specifically refer to only interfere with 5G signals. The meaning it expresses can be understood in this way : This refers to mobile phone jammers that can cover all standards in today’s 5G era, not only including current 5G signals, but also backward compatible with all past 2G, 3G and 4G signals.

Moreover, the 5G mobile phone jammer can only be regarded as an abbreviation. Although the name only expresses the meaning of including the mobile phone signal, in fact, by default, as a production factory, when the product leaves the factory, it is almost accompanied by the mobile phone signal The WIFI signal, Bluetooth signal, etc. are all used as standard configurations at the same time, and these signal types will be interfered together.

Regarding whether the GPS satellite navigation signal interferes: 5G mobile phone jammers usually do not use the jamming module in the GPS frequency band as the default factory configuration. Because GPS satellite signals are protected by law, no organization or individual can buy a device at will to interfere with the signal at will. Only some special departments, after having relevant authorization or permission, can we provide customized services for them .

Products such as drone jamming guns have only been developed in the last ten years. It is a countermeasure that can be quickly activated in the face of illegal approach of drones, or in other words: under visual conditions, security maintenance personnel After the drone target is found, the drone jamming gun will become the last defensive or counterattack weapon. Today, the miniaturized drone jamming gun can be worn on the go, which brings great convenience and practicality to security maintenance personnel.

From the analysis and comparison of the previous drone jamming gun products: the previous products, because of the preliminary research and development of new products, the design ideas have not been fully expanded, so the appearance, shape and structure of the products cannot be regarded as excellent. There are many subtle shortcomings such as the product is too large, the weight is too heavy, and the function is relatively simple.

According to feedback from some security personnel who have used drone jamming guns: the previous products were a bit too large in size and heavy in weight. However, in the process of carrying out missions, because more time is spent on patrol and inspection, the old drone jamming guns usually need to be held with two hands, even if some products with reduced sizes appear later, It also still needs to be held with at least one hand for extended periods of time. Once the patrol mission is longer, the physical and energy consumption of security personnel will increase a lot. Therefore, suggestions are made from the experience of end users: they very much expect that our drone jamming gun can be worn on the go.

So we newly designed a new style of drone jamming gun. Compared with the previous products, in addition to continuing to retain the basic technical indicators of jamming performance, we have done a lot in terms of the appearance and structural details of the drone jamming gun. Humanized design: 2 “QD fast buckle slots” are reserved on both sides of the device, and the operator can quickly disassemble and assemble the strap rope with “QD buckle”, which can be realized within 1 second Fast carrying function. In addition, we also designed a “GC mount” fast-connecting waist-mounted structure on both sides of this drone jamming gun, with quick-lock and one-key unlock functions. After using this waist hanging method, security personnel can directly hang the drone jamming gun on the belt when patrolling, and their hands can be completely released.

Among the numerous questions about mobile phone jammers in the examination room, the most frequently asked question is: Is there a maximum power shielding device? It is hoped that only one or two high-power shielding devices can solve the problem of signal shielding in all examination classrooms in a school. Why are the supervisors of the school examination room keen to ask such questions? Is the higher the power of the mobile phone jammer in the examination room, the better?

First of all, high-power shielding equipment is of course available, and we can also customize various power levels according to customer requirements, but based on years of experience in the field of signal shielding, the suggestion we need to express is: examination room type Mobile phone jammers are not suitable for high-power models, and the power of shielding equipment is not as high as possible.

The test room type mobile phone jammers are installed in the school, mainly to solve the signal shielding problem in each test classroom. This is mainly for building interiors. However, since the school’s teaching buildings are all reinforced concrete structures, each building has multiple floors, and each floor uses concrete or brick walls to separate several classrooms. For this type of building structure, if you want to cover the shielding signal inside it, choose a low-power test room mobile phone jammer and install it inside each classroom to achieve complete coverage in the form of a cellular network. This is the best solution.

So, let’s take a look at the situation of high-power shielding equipment? Usually, high-power shielding equipment is used in: outdoor open environment, or relatively transparent open area without obvious obstacles. What will happen if the customer strongly demands that a high-power mobile phone jammer must be used? The result is: the shielding effect of high-power test room mobile phone jammers is indeed better than that of low-power shielding equipment. However, due to the blocking and attenuation of the shielding signal by the building wall, only one or two high-power test room mobile phone interference However, it is not enough to cover all the classrooms in a building to completely shield the signal coverage. There will be many blind spots in signal coverage, and these blind spots have to be supplemented by low-power test room mobile phone jammers.

In recent years, many public security and special police departments have begun to purchase and assemble vehicle-mounted frequency jammers. Usually, these customers provide the vehicle chassis of an SUV, and then send the purchased frequency jammer equipment to the vehicle modification factory for modification and assembly. Make it a qualified and satisfying car frequency jammer. However, in the process of formulating a vehicle modification plan, the question of which power supply method to choose is the best, which often becomes the first problem that customers must solve.

Due to the large power consumption of the vehicle-mounted frequency jammer itself, it is generally required that the modified car can provide at least 5KW of power output, and there are even some vehicle-mounted frequency jammers, because there are many types of wireless signals that need to be targeted at interference, and it may be equipped with at least 24 A communication jamming module, which may require the modified car to provide at least 10KW of power output. With such a large power consumption, relying on the vehicle’s own generator or its own battery will definitely not be able to meet the power supply demand.

There are usually two options for providing power to the on-board frequency jammer on the modified car: the first is to choose a conventional gasoline generator or a diesel generator. The biggest advantage after adopting this method is: low cost and cheap price. The purchase cost of a gasoline generator or diesel generator can be settled at 10,000 to 20,000 yuan. However, this method also brings obvious disadvantages: a separate isolation compartment needs to be made inside the vehicle, and exhaust and ventilation measures need to be taken. Because the noise of this type of generator is very loud, the exhaust fume and exhaust gas need to be discharged to the outside of the vehicle as soon as possible. There is also a disadvantage: if the vehicle modified in this way is used in a parked and stationary state, if the on-site environment is a windless state, oily smoke and exhaust gas will quickly accumulate around the vehicle, which will interfere with the vehicle frequency. The instrument brings a very bad experience in use.

The second way is to choose a power take-off generator, which is installed next to the original engine of the vehicle, and the power take-off generator is driven by a belt to generate electricity. The advantages of using this method are obvious: low noise, stable and reliable output power, and no additional oil fume and exhaust gas. But there are also disadvantages, which will make customers entangled: the purchase cost of the power generator is relatively high, and the price of a set needs to be at least hundreds of thousands, and even as high as two to three hundred thousand. Another disadvantage: Not all vehicles can be used as vehicle chassis for on-board frequency jammers. Because it is necessary to consider whether there is a suitable space in the engine compartment of the vehicle to install the power generator.

If we have to ask the manufacturer to provide suggestions, our leading opinion is still: to choose the power supply mode of the power generator for the vehicle-mounted frequency jammer is the most suitable.

At present, electronic equipment used for drone defense and counterattack is emerging in an endless stream. Various methods such as drone detection, reconnaissance, and drone interference and strike have greatly strengthened defense capabilities. In the category of drone jamming, the drone jamming gun is a separate branch project, and some customers have raised questions: since there are relatively mature drone reconnaissance and high-power drones on the market now Why do you need to make this kind of gun-shaped drone jammer? What is the purpose of the drone jamming gun and the final protective effect?

The reason why the drone jamming gun is still in market demand is that it can be used as the last support weapon to effectively defend against drone attacks. Although there are indeed various drone detection products, the actual situation is that there may not be any manufacturer of drone detection equipment that dares to claim that it can achieve 100% effective detection of drone s. identify. If a small drone flies at low altitude and slow speed, hovers, or uses the blockage of buildings to fly around, it is extremely difficult for drone detection equipment for optical detection or for radar detection equipment. identified. Small drones still have the opportunity to break through the protected areas of some drone detection equipment, thereby having a devastating impact. When this happens, if the security personnel suddenly find that the drone has reached the visible range, in this case, what countermeasures can the security personnel take quickly? At this time, don’t think about using conventional guns to directly aim and shoot the drone. This is like a cannon hitting a mosquito, and the damage to the drone is almost zero. At this time, what can really play an effective strike against drones can only count on the drone jamming guns carried by security personnel.

In important security guard occasions, you can select a part of the personnel responsible for security protection and wear drone jamming guns with you. When performing normal patrols and performing security tasks, the overall situation can be realized by drone detection equipment to achieve global early warning, but once In the event of an emergency situation in which drones accidentally penetrate defenses, security personnel cannot expect to report to their superiors or mobilize remote drone strike equipment. The only way to quickly resolve the current emergency situation is the last guarantee. Sexual weapon: Take out the drone jamming gun and directly drive the drone away or make a forced landing.

I often receive inquiries from some customers. After understanding the functions and technical indicators of the product, I propose to complete the purchase transaction of mobile phone signal jammers through the e-commerce platform, but troubles arise: there are now many e-commerce platforms. Online transactions of such products are not supported, why? Why can’t e-commerce platforms sell mobile phone signal jammers at will?

If we go back to ten years ago, such as Taobao, Alibaba or JD.com, the e-commerce platforms at that time were developing rapidly after they started. At that time, products such as mobile phone signal jammers could be sold on the shelves. However, with the development of e-commerce platforms and the implementation of supervision and management policies, the review of products on e-commerce platforms has gradually become stricter. In this review process, mobile phone signal jammers are classified as sensitive commodities, which can be generally understood as: this is a product similar to police equipment, and it does not belong to popular daily department stores. Both buyers and sellers of signal jammers are subject to detailed and strict regulation.

Why are mobile phone signal jammers classified as sensitive commodities? This also starts from its functional characteristics. After all, a mobile phone signal jammer is essentially a device that emits wireless interference signals. Although there are many confidential places, examination rooms, prisons, and special management departments, it is necessary to limit the excessive use of mobile phones. Therefore, these needs can only be solved by purchasing and installing mobile phone signal jammers. However, if no regulatory measures are imposed on the e-commerce platform and some units or individuals are allowed to sell mobile phone signal jammers at will, the first possible consequence is: the use of mobile phone signal jammers in public areas will affect ordinary people. Normal mobile phone communication for the general public. The second possible consequence is that individual lawbreakers use mobile phone signal jammers to modify or engage in some technical illegal activities.

To sum up, it is worth affirming to prevent problems before they happen, e-commerce platforms strengthen restrictions on buyers and sellers, and the practice of not selling mobile phone signal jammers at will is worthy of recognition!

Anti-drone system is a general term, which can at least include: drone reconnaissance equipment, Drone data interception equipment, Drone jamming and strike equipment, etc. When the customer was planning the construction plan of the drone defense system, he had a question about the drone jamming equipment: Is it necessary to configure high-power drone jamming equipment in the anti- drone system?

Drone jamming equipment is usually divided into several types of applications, including: fixed drone jammers for position defense, vehicle-mounted drone jammers that can be transferred at any time at the airport, wearable or Portable drone jammers and more. Except for portable ones, the others are basically high-power products, and the RF transmission power of a single frequency band module will reach 10~50W.

No matter which detection method the drone reconnaissance equipment in the anti- drone system belongs to, their function is to discover or identify the direction and location of the drone’s invasion. Once the drone target is found, the drone reconnaissance equipment will output the target data to the control center. At this time, the control center should make a judgment whether to strike. The command is sent to the drone jamming device, and then the drone jamming device quickly starts the jamming strike mode.

What we need to know is that the detection range of most drone reconnaissance equipment is still relatively large, and the radius can generally reach more than several kilometers. It can be seen from this that the best matching mode for the supporting and linked drone jamming equipment is: its jamming and strike radius on drones is basically the same as the detection radius of drone reconnaissance equipment. This means that the radius of the interference signal is also required to be at least several kilometers. So the final conclusion is: It is recommended that the drone jamming equipment used in the anti- drone system should use high-power models.

After some units install the signal jammer, the mobile phone signal and WIFI signal will be interfered, which will cause the mobile phone to temporarily lose the function of answering and making calls, and cannot browse websites, watch videos, play online games, etc. normally. Therefore, some staff from such units often call us to ask: Once the signal jammer is turned on and working, what can be done to prevent interference?

From the conventional way of thinking, even if the interference signal is transmitted through the signal jammer, it can play the role of signal interference, then think about the problem in reverse: whether there should be a way, or whether there is an electronic product, Can the anti-jamming signal be used to counteract the jamming signal of the signal jammer? Some customers even ask: Is there an electronic device that can decipher the interference signal of the signal jammer, so as to achieve the purpose of anti-jamming?

However, the above can only be regarded as personal conjectures, and the actual results can never be achieved through conjectures. The interference principle of the signal jammer is very simple to put it bluntly. It imposes a strong interference signal on all communication frequency bands of the mobile phone. This interference signal is chaotic white noise. From the analysis of technical principles, it is precisely because Interference signals are disordered and irregular, so naturally there is no targeted way to decipher them. Then analyze it from the perspective of the so-called anti-jamming signal: once the jamming signal of the signal jammer is emitted and spreads around, this process is a process of natural attenuation as the propagation distance increases, and there is no imposition of a Anti-interference signals can play a role in suppression or elimination. So this approach doesn’t work either.

According to all the technical capabilities or means that can be imagined at present, we can only say: Once the signal jammer is turned on and working, there is indeed no way to achieve anti-jamming. For problems that cannot be achieved by technical means, we can only rely on some simple and brutal means, such as directly powering off the signal jammer or using a metal cover to completely buckle it.

From March to May every year, it is the peak season for the sales of mobile phone signal jammers in the examination room. Many schools are making sufficient preparations for the college entrance examination in June and the high school entrance examination in July, and invest special funds for standardized examination rooms. Construction, as an important safeguard against cheating in the examination room, the mobile phone signal jammer in the examination room is an extremely important link, so why does the school spend a lot of effort on these aspects every year? Does the mobile phone signal jammer in the examination room need to be replaced every year? What is its failure rate?

In fact, it is not true that the school upgrades the mobile phone signal jammers in the examination room every year. It is just that there are a large number of schools. Different schools do not carry out a project at the same time. They will formulate according to their own needs and budget. The specific implementation time is usually replaced every 4 to 5 years. During this period, inspection and maintenance will only be arranged every year.

The upgrading cycle of the mobile phone signal jammer in the examination room is generally synchronized with the upgrading time of the mobile phone communication system, or slightly lagged behind by 1 to 2 years. For example, more than ten years ago, when 3G mobile phones began to spread widely, schools needed to replace the mobile phone signal jammers in the examination room that only had the function of shielding 2G mobile phones with ones that could shield both 2G and 3G. In the same way, when the replacement cycle of 4G and 5G comes, the corresponding replacement of mobile phone signal jammers in the examination room will follow up.

The replacement cycle is relatively long, at least once every 4 to 5 years, but the daily troubleshooting of mobile phone signal jammers in the examination room should be persisted for a long time, otherwise it will lead to low equipment integrity and failure rates On the high side. There are many reasons for the high failure rate, not only including the frequency of inspection and maintenance, but also closely related to the quality, process and use of the product itself, whether the transfer and transportation are safe, and whether the user cares about and protects the product.

After years of statistics and feedback, as a manufacturer of mobile phone signal jammers in the examination room, after nearly 20 years of experience accumulation, the quality and craftsmanship of the product itself have been greatly improved, and the failure rate in this regard has been reduced. down to a very low level. Today’s products are even more packaged with an overall shell, which is no longer like the past: antennas, power supplies, etc. are all connected externally, and now they are all built-in, which also minimizes the possibility of man-made damage to the device.

By 2023, the 5G era has been opened for more than four or five years, and the research and development and testing of 6G technology have been steadily advancing. The industry usually expects to fully enter the 6G era by 2030. So, what is the design idea and development direction of mobile phone signal jammers for the 6G era?

Looking back at the time when mobile phones were upgraded from 2G to 3G, and then from 3G to 4G and 5G, each upgrade cycle was only 5-8 years. The time span for upgrading from 5G to 6G is likely to reach or even exceed 10 years. . Every upgrade in the past will enable new frequency bands to meet the needs of higher network speed and wider bandwidth. The mobile phone signal jammer also adopts the method of continuously increasing and stacking multiple different frequency bands, so as to achieve complete coverage of all mobile phone signal types, in order to achieve a reliable interference effect.

In the current 5G era, because the original 2G, 3G and 4G signals have not completely withdrawn from the network, although 4G and 5G signals are the mainstream in cities, in vast rural areas or open areas, 2G and 3G signals are still The main frequency band to maintain the normal communication of mobile phones. Therefore, the mobile phone signal jammer must take into account all mobile phone signals, which makes a 5G mobile phone signal jammer usually need to be equipped with at least 10-12 signal jamming modules, corresponding to different mobile phone standard frequency bands. After the advent of 6G mobile phones in the future, mobile phone signal jammers that support 6G must also follow up immediately. What is the way to follow up? What can be predicted now is that the future 6G network speed will be faster and the bandwidth will be wider, which will inevitably determine that higher frequency frequency resources may continue to be used in the future. Once this is the case, the future 6G mobile phone signal jammers will increase simultaneously. Higher frequency 6G jamming modules are an inevitable development trend.

However, if we simply increase the frequency band as in the past, it will definitely make the appearance and size of the 6G mobile phone jammer continue to increase. As a professional manufacturer of mobile phone signal jammers for many years, we put forward our design ideas and development direction: we should focus on the future development trend, and start from the current 5G mobile phone signal jammers. Future module upgrades can reserve the assembly space for new modules. After the 6G module comes out in the future, the original equipment and its modules can continue to be used, so that unnecessary waste will not be caused.

With the approach of the exam season, many schools have started to prepare for the purchase and installation of mobile phone jammers in the exam room. The selection of products and how to install them in the exam room in the future are issues that customers should pay more attention to. Different product models, their functions, usage methods, installation methods, etc. will have certain differences, so the question arises: What are the precautions for the selection and installation location of mobile phone jammers in the examination room?

In terms of choosing the style of mobile phone jammers in the examination room, the current mainstream products all adopt the structural style of the built-in antenna. The advantages of this type are: simple and beautiful appearance, and no complicated assembly and connection are required for installation and use. It is necessary to power on the host of the mobile phone jammer in the examination room and turn on the switch of the host.

There are still some products on the market that have maintained their appearance for more than ten years, that is, the traditional mobile phone jammer in the examination room with an external antenna. Nowadays, a full-band mobile phone jammer in the examination room that can support all standards such as 2G, 3G, 4G, 5G, etc. usually needs to include at least 10-12 omnidirectional antennas. It’s not very good looking, just like a “hedgehog”. Moreover, so many antennas are directly exposed, so they are not anti-destructive and are easily damaged by humans. If it is not fixed or wall-mounted, the antenna needs to be disassembled or tightened one by one every time it is used. hidden trouble.

When the mobile phone jammer in the examination room is installed in the classroom of the examination, special attention should be paid to where it is installed. If wall-mounted installation is adopted, our suggestion is to install it at the upper end of both sides of the blackboard in front of the classroom or at the back, and the height from the ground is recommended to be 2-3 meters, which can preliminarily prevent some students from maliciously touching or damaging the mobile phone jammer in the examination room . It can also be installed on the middle wall on both sides of the classroom. This can achieve a better coverage effect.

If it is a form of temporary use and non-fixed installation, our suggestion is to place it above the classroom platform, or in a corner of the classroom. First, tables, chairs or bookcases are required as supporting surfaces, and mobile phone jammers in the examination room should be placed On these support surfaces, this allows the device to have a certain height difference from the ground. We mainly remind customers not to place mobile phone jammers in the examination room directly on the ground, as this will greatly reduce the transmission distance and coverage of shielded signals.

In the examination room of many large-scale examinations, in order to prevent students taking the examination from carrying their mobile phones without permission, secretly using mobile phones to contact the outside world during the examination and cheating in the examination, the installation and use of mobile phone signal jammers in the examination room is the most commonly used technical protection means . However, with the progress of the times, the peripheral electronic products that match mobile phones have flourished in recent years, such as smart watches or electronic bracelets, etc. Some smart watches can even be completely separated from the mobile phone, and can communicate with the outside world and communicate with the outside world by themselves. For data transmission, the question arises: can the mobile phone signal jammers commonly used in examination rooms block smart watches?

If you carefully understand the functions and technical parameters of smart watches, you can know that no matter what the appearance of these smart watches is, or there are more or less differences in functions, there will be no obvious difference in their basic communication modules, or It uses the WIFI module to bind with the mobile phone to complete the communication, or it has a built-in SIM card, which is equivalent to a simplified version of the mobile phone. After this analysis, the questions raised above are easy to answer: since the mobile phone signal jammer in the examination room can completely shield all mobile phones, the smart watch is almost equivalent to a simplified small mobile phone, so the mobile phone signal jammer in the examination room Smart watches can also be blocked.

Some students may be lucky enough to think that electronic products such as smart watches or electronic bracelets can be brought into the examination room. As everyone knows, in any formal examination, not only the mobile phone signal jammer in the examination room will directly block and block the signal, even such electronic products When the product enters the examination room, the invigilator will fail to pass the inspection with a metal detector.
