What needs do we need GPS jammers to meet?

Since the GPS system has been installed in place, it is of great help to us. Based on the GPS system, we have developed many devices to help us carry out military use and life. But the GPS system also poses a very dangerous threat to us, it can easily reveal our location. Anyone can easily find our location by putting a small GPS device in our car or even pocket. In order to protect ourselves from the danger of illegal tracking, we need GPS jammers. GPS jammer is an anti-GPS electronic device, which can transmit a stronger signal to cover the GPS signal with the same frequency as the GPS signal. Since this signal from the GPS jammer is stronger than the GPS signal, it may cover and hide the GPS signal, so that all GPS devices in a certain area cannot receive the GPS signal and therefore cannot work normally.

At the same time, the market will increase to about 1 billion US dollars in about 2-3 years. The total amount of these transactions in the global arms market is not high, but it can be regarded as the performance of a major breakthrough in the field of anti-UAV by Beijing Shenzhou Mingda. The outstanding performance of Beijing Shenzhou Mingda’s anti-UAV technology is due to a series of anti-UAV control products developed by the company in recent years. The company launched the DZ01 bag single-soldier portable low-altitude UAV control system in early 2017. , Launched the third-generation product DZ01 PRO gun-type single-soldier portable low-altitude UAV control system in May 2017, and officially launched the fourth-generation portable four-channel strike gun DZ03 PRO in 2019. The latest generation strike gun has a higher single-channel power , The interference distance is longer than the previous two generations of products (the interference distance is more than 2.5 kilometers), and the current advanced interference technology is adopted to deal with the interference of the flight control signal and the navigation signal to achieve a faster and more accurate interference effect. Really achieve long interference distance, low radiation, lightness, and simple use. Individual soldiers are portable and can achieve non-destructive precision strikes against drones from the sky!

Anti-terrorist forces acquire radar jammer

NSG and CISF will have mechanisms such as electromagnetic systems, which incorporate radars and radio frequency jammer, and may have the power to shoot down any object from low altitude to low altitude.

The National Security Agency and the CISF Industrial Security Agency may have the right to shoot down “rogue” low-flying objects such as drones and gliders under a new policy being finalized.

Interior Ministry officials said a draft policy on the operation of unmanned low-level flying objects will be released soon to address the possible use of drones, gliders and other tools to conduct terrorist attacks.

The Union Secretary of the Interior recently held a meeting with representatives of the Indian Air Force, Ministry of Civil Aviation, Central Industrial Security Force (CISF) and others stakeholders to discuss this issue.

“The draft drone policy is in its final stages. It focuses on regulating the use of unmanned aircraft and similar flying objects at low altitude. The policy itself is expected to be released into the public domain this time. this month to consult with stakeholders. ” the official Say.

The official said that if the National Security Guard (NSG) and the CISF consider him a “thug,” they may have the right to shoot down any low-flying object that “makes mistakes.”
Both forces will have defense mechanisms such as electromagnetic systems, which will have built-in radars, radio frequency wave jammers and detectors.

The policy will have a preventive function to ensure that terrorist organizations or other anti-national elements will not abuse any low-flying object.

The policy was formulated after several drones were discovered at airports and border areas, which hampered air traffic and caused security concerns.

“There is a need to supervise drones to prevent their abuse in sensitive areas like airports. This policy will stipulate how to control thieves who operate drones.” Another official said.

The policy will have two aspects of enabling functions: granting permission to use drones at international borders and enabling national protection of important facilities and disaster relief operations.

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.

Jammer Telephone and radio waves. What are radio waves? I don’t have many. Radio waves are electromagnetic waves, which are electrical waves that travel through space. Radio waves of various frequencies are used in various places in our life. Cell phones can receive signals using radio waves. There are multiple deterrents to the radio frequency used on the phone. The function is also different. Effective when used correctly. Bring convenience to our lives.

A smartphone that can be connected to the Internet is connected to a mobile phone base station (base station) via radio waves, and transmits voice, characters and images to the other party via a communication line. We support practical life. Communication is possible within a radius of several kilometers. It is a wifi jammer, which emits radio waves, which is essential for wireless communication. However, many problems also arose. Someone is still talking loudly in the car. Someone is walking typing a cell phone email. At such times, I want to cut off the telephone signal. I want the signal to stop working. Introduce disruptive equipment. I am using a cell phone jammer to block the radio waves on the train. The radio wave disappeared in the blink of an eye, out of range. Interference from public transport is a problem. Therefore, the correct use of jammers is very important. The use of cell phones is a problem. Place devices that interfere with radio waves from cell phones. It is said to have been started after getting tired of rude customers. The device emits parasitic radio waves. It can emit enough radio waves to interfere with the call. This will worsen the radio waves received by the mobile phone. The phone cannot make or receive calls. This portable jammer goes beyond the “weakness” defined by the radio law and requires a license.

5G jammers, full body scanners on Punjab Prison Minister’s menu to improve work

Ministers said no one except the superintendent was allowed to carry cell phones in prisons. “If an officer is found in jail with a cell phone, the first thing we would do is suspend him.”

The installation of 5G jammer, full-body scanners and other sniffer dogs outside the prisons is the plan that the new prison minister Sukhjinder Singh Randhawa has drawn up for a reform of the department.

The minister, who has firsthand experience of phone phone threats in prisons, told a press conference on Tuesday about one of an inmate’s congratulatory calls: “5G jammers will soon be appearing in the state’s central prisons. A proposal has been sent to the Union Ministry of Interior. ”

“Now we only have jammers for 2G and 3G signals. If we install 4G jammers today after a tremendous effort, it will be out of date when 5G comes in. So we’re trying to install 5G jammers, ”Randhawa said after a meeting with prison officials.

Incidentally, the government’s official press release in the evening spoke of the installation of 4G jammers. “We have three detection dogs in the prison section. We plan to add seven more to check drug and cell phone use in prison complexes, ”the minister added.

Only supdt can transport telephones in prisons

The minister added that no one except the superintendent is allowed to carry cell phones in prisons. “If an officer with cell phones is found in prisons, the first thing we would suspend,” Randhawa said, adding that over 1,500 cell phones were recovered from prisons in 2017.

“To prevent this from happening, the additional chief secretary will instruct the district police chiefs to investigate mobile recovery cases. All prison staff involved are severely punished, ”he said.

The minister added that 651 inmates were found to be HIV positive and said the department would improve health facilities in prisons. “We are also planning to introduce health insurance for inmates. I will also ask that doctors be permanently deputized to prisons. The health department only sends its doctors to deputation for six months, ”he added.

He said the prisons were almost full with 22,375 inmates versus the 23,218 capacity. There are 1,119 women and 132 foreigners. Around 40% of inmates who were fined were booked in cases related to the NDSP law. Around 60% of the prison population (13,000) are under-tried.

Benefits of installing shields in dormitory areas and examination rooms

In recent years, due to the widespread popularity of mobile communication tools such as mobile phones, cheating using mobile communication tools such as mobile phones has become a “secret weapon” for some candidates to improve their test scores. These candidates do not seek hard work on weekdays, but want to use them when taking exams. Some illegal means, or organizations and individuals who listen to some illegal test-disclosure vendors, or provide answers for profit, want to use their mobile phones as answer receiving tools or transmission tools to obtain ideal test scores through cheating, which seriously damages The fairness and seriousness of the exam! It is a great harm to most other students who usually study hard and learn from the truth!

In order to strictly discipline the examination room and ensure fairness and justice for each reference person, installing a mobile phone shielding network intelligent management system or a wireless signal jammer device is one of the most effective ways to prevent candidates from cheating through mobile phones and other communication tools.
