Answer common questions about mobile phone signal jammers

1. Is there radiation?
If high-power equipment, such as 5W (37dBm) above the host computer may also have greater radiation. Generally, the output power of mobile phone signal booster is within 200mW (23dBm). After reaching the antenna, it is generally within 5mW (7dBm). After other losses, the indoor signal after installing a cell phone jammer is generally around -50dBm to -75dBm. Good outdoor signals are generally around -40dBm to -75dBm.

When the mobile phone is talking, the GSM mobile phone is talking in a weak signal environment, and the worst radiation power can reach 1W (30dBm). After installing the amplifier, the radiated power of the mobile phone call is about 10mW (10dBm). It can also be said that after installing a small power amplifier in a poor signal environment, the mobile phone reduces radiation when talking.

2. How to distinguish the quality of signal amplifier?

1. Look at the workmanship and choose the brand. If you use more, you can take it apart and compare it internally.

2. There are many inferior signal amplifiers on the Internet, mainly because some circuits for optimizing signals, such as automatic gain control, are omitted. Generally, there are less than 80 devices, and the host with complete circuits generally has more than 200 devices.

3. Inferior cell phone signal amplifiers will cause serious interference to the base station after a large number of installations, making it impossible to make calls when the signal is full. Of course, there are interferences of good quality, but the interference of the same power is several times and dozens of times smaller.

3. Why can’t I make a call when the installation signal is full?

The signal amplifier is a simple device developed at the intermediate frequency of China Mobile and China Unicom. If there is no signal or very weak indoor China Unicom and China Mobile, it should be no problem to use this device. If one party has a full signal and the other has no signal, interference will occur in this case, so it is not recommended.

Telephone jammers are necessary for a good environment for important meetings

We’re tired of being interrupted, especially in important places, and I’m tired of the phone ringing. He was very angry when the leader was chairing an important meeting and was interrupted by the ringing of the cell phone. The frequency jammer is used in the conference room so that the conference has a good environment.

With the popularity of cell phones, cell phone ringtone makes people more tired, especially in some quiet public places. In many places, cellphone use is prohibited as it affects others, affects others to rest or work, and even affect the websites such as the use of the instrument and the moderating effect of cellphone. While there are clear instructions on how to ban cell phone use, there are a lot of people in these places using gas stations for example, as we use cell phone at gas stations is dangerous and probably caused the explosion.

We should know that the important national meeting will last for many days. The content of the meeting must be kept strictly confidential and must not be interrupted by the outside world. Therefore, the mobile phone is prohibited. Not only is this a national meeting, but it was also adopted at a series of corporate meetings where cell phones were banned and cell phone blockers were gradually installed. What do you think is reasonable about Office installation of the cell phone jammer?

Not only are cell phones banned in gas stations, but many public places are starting to ban them. It may also be banned in some private places. We have heard of cell phone jammers being used in schools and cell phone jammers being used in prisons to disable cell phone signals and protect prison security. What about the conference room? Have you seen any examples of this? With people increasingly relying on cell phones, many companies are starting to install an adjustable device in the meeting room. The cell phone jammers will be held in the meeting. The meeting leader conducts the meeting properly without the ringtone intervening. opens and adjusts the disruption area in the conference room. This not only affects the normal use of the outside, but also provides the environment for the meeting.

If the ringing of a cell phone interrupts the speaker’s thinking at an important meeting, it will upset them and distract attendees from the meeting. The cellphone in the meeting room with important rings is rude behavior. Therefore, in many meetings, before the prompts begin, the phone will shut down or put into mute state. Many companies are not allowed to take cell phones with them while attending the meeting, visible on cell phones in the Internet age, the use of cell phones is regulated more and more clearly.

Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

GPS signal jammer

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.

Why use signal jammers in educational institutions?

The mobile phone is undoubtedly a very convenient tool. However, depending on the time and place of use, normal public order may also be hindered. Such as libraries, classrooms, etc.

There is no doubt that smartphones have extraordinary functions that can theoretically promote student learning. But the fact is that despite the best efforts of parents and teachers, children still mainly use mobile phones to access digital entertainment.

Needless to say, mobile phones should not be used in classrooms. Mobile phones are not allowed in the classroom, but teachers don’t want to enforce the rules. They often complain that I should find a solution so that they don’t have to argue with students. A friend of mine used to be a teacher. His students used to send text messages in class and later bought a portable cell phone jammer. Then all the students felt that their phones could not receive any signals.

The principal of high school purchases cell phone signal jammer from dealers to prevent students from using cell phones in school in violation of school district policy. First, he may be tired of abusing mobile phones on campus, and his decision may be due to cases where the learning environment he tried to create was seriously damaged. However, it is frustrating that education efforts, deterrence strategies, formal policies, and vigilant supervision and sanctions have not sufficiently reduced the problem.

smartphone signal blocker

The school will restrict the use of students’ mobile phones during class, so as to clearly promote students’ academic success and safety. At present, most schools will let teachers install signal jammers in their classrooms. But this piecemeal approach leaves teachers with insufficient support to cope with difficult and potentially unsafe tasks that provoke students to restrict destructive phone use.

Some people think that mobile phones should not be used during learning because children will not be fully focused on their work. Children can go online to play games, but it does not help their learning. Children will be distracted by the ringtones on their phones or the flashes of other children taking pictures with their phones. Mobile phones should not be allowed to go to school during the study period.

In addition to sending text messages, jammers can also effectively prevent students from cheating on their mobile phones. Cheating is always repeated. Facing this situation, educators must use jammers to prevent cheating.

Now not only educational institutions in China are using mobile phone signal jammers, more and more countries are introducing signal jammers into educational institutions.

What are the effects of communication base stations on the social economy?

Why build a communication base station?

Regardless of the mobile communication system, the calling and called users do not directly transmit information. The calling user transmits the demand signal and transmits it to the central computer room through the base station. The central computer room analyzes this information, determines the location of the called user, GSM jammer and transmits relevant information to the base station near the location of the called user, and the base station transmits to the called user. Since each base station has coverage distance and access capacity limitations, it is necessary to build multiple base stations to form a communication network to achieve seamless coverage of the entire area.

What is the effect of mobile communication on the social economy?

The development of mobile communications has had a profound impact on the reform of the telecommunications industry, economic growth, independent innovation and social life.

First, it has promoted the change of Chinese people’s concepts and led to the rise of communication culture. Over the past 20 years, my country’s mobile communication network has continuously expanded its coverage and enriched business content, expanding the breadth of people’s communication, deepening the depth of people’s communication, expanding the time and space of communication with each other, and accelerating people’s ways of thinking, working, and Changes in lifestyle. The reduction of information exchange cost brought about by convenient mobile communication has expanded people’s information sources and effectively promoted the improvement of national quality.

The second is to promote the improvement of social and economic operation efficiency and economic development. Through continuous innovation in business services, my country’s mobile communications industry has effectively helped related industries to reduce operating costs, avoid operating risks, improve management efficiency, promote the improvement of social and economic operation efficiency, and bring double value that is difficult to measure with money.

The rapid development of my country’s mobile communications has played a positive and direct role in attracting foreign investment, becoming a global electronic communications manufacturing base and important research and development center, and has promoted my country’s mobile communications manufacturing enterprises to enter international competition, thereby changing mobile communications systems and mobile phones. The global layout of the manufacturing industry has greatly stimulated the development of the domestic communications manufacturing industry and even the global communications manufacturing industry.

The third is to promote environmental protection. In 2009, the “thumb economy” represented by mobile phone text messages for New Year greetings reappeared. According to estimates, the number of mobile phone text messages sent nationwide during the Spring Festival holiday exceeded 18 billion. Compared with the previous paper greeting cards, 4,000 paper greeting cards are about one tree. Calculated, it is equivalent to cutting down 450,000 trees. In today’s era when paperless office is promoted, mobile communication platforms extend this concept to the extreme.

The role of drones in future warfare, what about drone jammers?

War is entering the era of drones faster than expected, and the “high altitude danger” of civilian drones is increasing, except for large drones like the Global Hawk. At home and abroad, the phenomenon of “black flying” and “flying flying” has emerged one after another, which has attracted more and more attention to security monitoring issues such as civil aircraft taking off and landing, eavesdropping in secret areas. In fact, the increasing number of unmanned aerial vehicle (UAV) crimes makes people pay more and more attention to the management of unmanned aerial vehicle (UAV).

drone signal jammer

The drone signal jammer market is developing rapidly, and UAVs are now playing a role in aerial photography, mapping, delivery, rescue and other fields. However, “problems” followed. These problems affected the order of aviation and the penetration of sensitive areas… These phenomena even led to the rapid development of the derivatives industry and unmanned aerial vehicles (uav). Equipment and service providers, unmanned aerial vehicle (UAV) “predators” have also benefited a lot from it, which brings huge development opportunities to unmanned aerial vehicle (UAV) companies.

The Chinese military has been equipped with the ability of the US military to use drones to interfere with radiation weapons. Large electronic warfare equipment can even destroy and capture enemy large drones. For example, Russia’s “automatic” countermeasure energy response system has some powerful functions that the outside world has not yet realized. The radar system can suppress 50 aircraft at an altitude of 30,000 meters, and can also conduct electronic attacks on fighter jets and unmanned aircraft within a radius of 100 square kilometers. In October 2011, Iran captured the US RQ-170 stealth drone “outpost” using an electronic countermeasure system provided by Russia.

Example of installation of UAV countermeasure equipment by cultural relics protection unit

UAV “black flying” harm

There are blind spots in the supervision of drones in my country, and the large-scale use of drones brings hidden dangers to public safety. Drones that were originally used for legal purposes are increasingly being used for criminal purposes. The public has become increasingly aware of the harm that drones may cause. UAVs can smuggle drugs; UAVs can spy on privacy/technology; UAVs can affect civil aviation – close to collisions; UAVs may appear in sensitive areas, key locations, cultural heritage protection units and government facilities; UAVs may even Can shoot automatically…

Because the intrusion of drones has brought great harm to everyone’s lives, many units have begun to install drone countermeasures. Let’s take a look at this fixed drone counter independently developed by Texin Electronics. Control the efficiency of the equipment.
