The GPS jammer itself is usually a small independent frequency transmitter that can send interference signals within a range of 5 to 10 meters. These devices are usually plugged into a cigarette lighter or USB/charging port and require almost no power supply. Although GPS jammers are illegal in most places, they can be purchased online and appear in many forms, such as: B. Wi-Fi jammers, Bluetooth jammers, remote control jammers or drone jammers.
Although most markets still use 4G networks, 5G is the mainstream signal in the future and will soon occupy the market. With the greatly improved transmission speed, whether in life or work, the utilization rate of 5G has greatly increased. Our company has always put the development of 5G jammers in a central position, which is essential to keep up with the times and adapt to market changes and demands.
If you need a powerful signal jammer, the high-power desktop jammer is the most powerful indoor equipment we have. There are a large number of signal jammers in high power jammer, designed to provide a higher interference rate, and you can also get the ideal type of high-power signal jammer.
Cell phone jammer, also known as cell phone blocker or mobile phone jammer, are devices that prevent wireless connections from being established in their surroundings. This creates artificial dead spots that are supposed to prevent the use of cell phones and smartphones. Cell phone jammers are primarily aimed at cell phone networks, but WLAN and GPS are also affected by them. The range of the Handy-Jammer depends on the model.
The signal jammer sends a signal of the same frequency (noise or pulse) with a certain strength on a certain frequency, thereby superimposing the original transmission. If jammers are used exclusively, they are called strategic jammers. These devices are also called jammers, and the process is called noise interference.
Cell phone jammer-it feels inaccurate after all, we use data to speak. According to related reports, the current average download speed of Chinese mobile phone users using 4G networks is 28mbit. If you add up the national internet speeds, the average download speed is about 3-4m/s. In fact, this value is enough for us to use the network normally, except where the signal is bad.
With the development of science and technology, the positioning, tracking and monitoring of mobile phones have become the most important reconnaissance methods and sources of intelligence in countries around the world. As long as the mobile phone is carried in secret-related places, whether it is used or turned on, it is extremely likely to cause leakage of secrets and cause serious harm to units or individuals, even the party and the state.
Cell phone signal booster is also called mini repeater, also called cell phone companion. From its name, the signal booster knows that its function is to amplify the signal. Amplifiers that specialize in amplifying cell phone signals are called cell phone signal boosters.
Many companies will install signal jammer in conference rooms. The main reason is that they don't want the call to interfere with the progress of the meeting. So what are the technical advantages of the signal jammer in the conference room? What are the installation and use methods of the signal jammer?
The shielding effect is different according to the distance between the location and the base station, and the shielding range is mainly determined by the strength of the magnetic field. Can recommend handheld 4-way and 6-terminal cell phone jammer. Low-power shielding through walls will weaken the signal. If you need to go through walls, it is not recommended to buy low-power ones.
Since 2001, a total of 11 cases have been published in the "Communiqué", which ranks among the forefront of basic courts in the country. In order to prevent the leakage of important information of the government unit, signal jammer are arranged around the unit to ensure the information security of the government unit.
The working principle of mobile communication is that within a certain frequency range, wireless devices (mobile phones, etc.) communicate with the base station through radio waves, and complete data and sound transmission with a certain baud rate and modulation method.
Police said the suspects went to shopping malls, parking lots, leisure centers and other public places where they loitered in the parking lots and remotely intercepted their victim's car lock with a GPS jammer.
This way, they gain access to vehicles, steal valuable items and money, and lock them.
The big advantage of sending a fighter drone with countermeasures instead of attempting to do so on the ground is that it can reduce the power of the signal jammer near the drone, which reduces the interference with other RF equipment in the area. The rogue drone is specially designed for them.
In order to ensure the security of classified information, a "cell phone jammer" should also be placed in the classified area to block the communication of mobile terminals that are intentionally or unintentionally brought into the classified area.
Members of the group's leadership team also participated in the group discussions and exchanged views on issues of concern to everyone. In order to protect participants from outside interference in the conference room, the conference room signal jammer is placed around the conference room to make the participants focus more on the meeting and improve the overall quality of the meeting.
Large-scale musical instruments such as organs, pianos and advanced audio and video equipment imported from the Czech Republic, Germany, Japan and other countries have made the sound effects of Xinghai Concert Hall famous at home and abroad. Mobile phone signal jammers are used in the venue. In order to protect participants from external interference and focus on enjoying the influence of art, signal jammer is installed around the venue to allow participants to enjoy art.
As the activity base of the Guangzhou Municipal Party Committee Propaganda Department and Enterprise Cultural Association, the city-wide corporate culture and art festival is held here every year. cell phone jammer is used in the venue. In order to protect participants from external interference and focus on enjoying the influence of art, signal jammers are installed around the venue to allow participants to enjoy art.
Signal jammer is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of mobile phones is prohibited. It is understood that cell phone signal blockers on the market can limit cell phone signals to 500 meters away from the launching station.
Of course, in terms of energy saving and heat dissipation, Borch's space-time built-in cell phone jammer cannot be compared with Borch's space-time external cell phone signal blocker. From the perspective of external structure, the built-in mobile phone signal shielding device integrates the transmitting antenna, power supply and heat dissipation fins in an external plastic shell, which is more beautiful in appearance, plug-and-play, and requires complicated antenna connections, plug-in power supplies, etc. advantage.
If you want to stop the GPS orbit, you need to choose a 2-in-1 jammer (low-cost 2G GPS jammer)) at least! Because when you only use a small GPS jammer to block the GPS, it will automatically activate the built-in SIM card to achieve GPS positioning.
First, let's popularize the relationship between price and power. The shield is divided into low power, medium power and high power. Low power, that is to say within 2W, this 2W refers to 2W per channel. If it is 8 channels, the cell phone jammer is also 16W. This is suitable for home use, small meeting rooms, etc., generally within 15 square meters.
We all know that the signal jammer is a weapon dedicated to anti-cheating, but it is not only used for cheating, but can also be used in all walks of life, such as: large conferences organized by the country, training institutions, and the military. After we know the purpose of the signal jammer, we don't know how the signal jammer manufacturer produces such a signal jammer? Let's take a look at the situation of Shankino's signal jammer manufacturers.
The first is to test the coverage distance of the cell phone jammer device. Don't just use one of the two network mobile phones to try it out. During the exam, cheating candidates use different mobile phone networks, especially 4G mobile networks (4G networks use broadband high-speed transmission, if the power of the mobile phone signal masker is not enough, it may not be able to cover 4G).
The signal 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 communication, and the mobile communication cannot detect the normal data sent from the base station, so that the mobile communication cannot establish a connection with the base station.
In view of the RF interference problem of GSM mobile phones, GSM mobile phones work in TDMA mode, and RF transmission and reception are not performed at the same time. The basic principle of reducing RF cell phone jammer is to strengthen matching and isolation.
Some simpler devices can only block one set of frequencies, while advanced cell phone jammer can block multiple types of networks at the same time, cutting off the signal of dual-mode or triple-mode mobile phones, making it impossible to switch between different networks and find open signals. Some high-end jammers can block all frequencies at the same time, while others can be set to block specific frequencies.
