Can a mobile phone signal jammer shield 4G signals?

Today, I will talk to you about whether the mobile phone signal jammer can effectively shield the 4G network signal? This topic will help everyone have a more comprehensive understanding of the signal jammer. Next, the editor summarized a few pieces of knowledge about mobile phone signal jammers.

jamming signal

1. In addition to the 4G network signals that have been widely used, the commonly used mobile communication network signals include the 3G network signals that were popular in the past few years, as well as the 2G network signals used by some elderly phones. Although 5G network signals have become a topic of discussion by many people, it will take some time before they can reach 5G networks.

2. The first thing to be clear is that the mobile phone signal jammer can shield 4G network signals. When the mobile phone is operating in a certain frequency range, the mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method. Aiming at this communication principle, the mobile phone 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 phone, and the mobile phone cannot detect the normal data announced from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested in the phenomenon of searching the network, no signal, no service system, etc.

3. The key to shielding 4G network signals depends on the frequency supported by the selected mobile phone signal jammer. The current 4G frequency range is very wide, from 800M-2. 4G, if you want to shield 4G signals, it depends on what you use for shielding. How much bandwidth can the device support? Because some of the 4G frequency band almost overlaps with WIFI 2.4. Once you shield the 4G signal, the WIFI and Bluetooth in the shielded area may not work properly. Therefore, whether the 4G signal can be shielded depends on the function of the shielding product, whether the device has a 4G signal shielding module.

Jammers can prevent the transmission of negative emotions

The humming and noise of the phone in public places could cause negative emotions in others, this behavior is outrageous, especially in theaters, cinemas, restaurants, concert halls and speeches, etc. In order to avoid such a loud voice, a local GPS jammer installed at these locations, in particular 2G 3G 4G, GPS, WiFi, Bluetooth, LoJack jammer, is blocked.

Speech is important to show whenever speakers hope to achieve their goals through individual performances. No one likes his speech brutally interrupted by some viewers of the phone, then he felt neglected and disrespectful – and sometimes beat your man is not your competitors, but the vandals. You are these attacked vandals, and worse still, the behavior seems to be understood and appreciated … it really starts, becoming a normal trend, it was to make a speech to the public, there is always a chance that they will suddenly drop out of other phones.

Therefore, we recommend that you install phone jammer before speaking. The equipment can be up to 10 meters, must calculate the area of ​​the place, the device if the number of cell phone jammers. 10 antennas are switched to different interference objectives, as we mentioned in the first paragraph, or we can make them all work. This means that almost the phone can ring and work there (cannot receive and receive phone calls and text), you can use the source Wi-Fi signal, data can be transmitted via Bluetooth, no GPS signal and LoJack, no follow-up. In short, no mobile device can run speech, they can focus on performance and avoid interruptions.

In order to avoid loud noises in the voice telephone, you can better use the jammers.

Use jammer properly and do not hurt others’ right

More and more people are increasingly concerned that their privacy is leaked and that their privacy is consciously protected. We all know that there are many ways and tools to tacitly steal our personal information, and even unwittingly.

We use different smart devices every day such as GPS navigators, laptops, smartphones and so on. These devices give us a lot of convenience, but there is no doubt that your personal information has leaked from these devices too. You can say that your wireless gadget is the double agent of the stolen person.

We use Wi-Fi connection, but we don’t know that it can be hacked easily. We use Bluetooth, we have never heard of Bluetooth hacker technology. If we use GPS to determine where we are and how we get where we need, we will find gps tracking there.

From these aspects, it is not difficult to understand why these cell phone jammers are so popular in the world. This is because people want to protect their privacy.

But why jammers are illegal in many countries because their use can affect other agencies, like gps jammer can interfere with other GPS navigation. So when we use jammers to protect our privacy, we shouldn’t forget the rights of others. The jammer should be used accordingly.

This is the advice we give you to use the jammers appropriately:

Do not use traffic jams in public places. We recommend that you use blockers in a private place. Don’t try to open it in public places because you can violate the rights of others. You are free to use jammers in your car or at home. Also, choose a signal blocker with the right work area that you need to avoid to bother someone else.

We have the right to defend our privacy, but we should not violate the rights of others. You should remember that other people want to communicate freely. Don’t try to block them. Because there can be an urgent call.

Jammers can help in the war on terrorism

Terrorist attacks have occurred frequently in recent years and are causing great harm to people. Today, the fight against terrorism has been widely discussed and is one of the things people need to watch out for. We find an important means of the terrorist attacks is a bomb attack that causes great damage as a cruel and common means of the terrorists. Therefore, an important thing to fight a terrorist war is to prevent different types, sizes and powers of bomb devices.

There are many types of bombs. Fortunately, the government also has a special bomb disposal force to deal with these various bombs. However, the most difficult terrorist attacks are not able to tear the bomb apart, but to find and prevent bomb attacks. Can you imagine that when you are on the square, was there a sudden bombing in the cinema? It was too late to prevent it. With regard to the precautionary approach, you know that most of the terrorist attacks are triggered by a simple phone call. At this moment, if there is a suitable signal jammer near the place where the bomb is installed, you can make sure that nothing happens because the signal is not being transmitted. Such cell phone jammers are used by military and law enforcement agencies.

In addition, when we refer to the fight against terrorism, we should mention that most countries have started to take these measures and have installed special woes on important roads where the President has witnessed. For this reason, because there is no signal that can trigger a bomb even when it is installed, there is no accidental danger.

The good news is that blocking technology is evolving and its functionality is getting better and better. Some of the best high power jammer can block radio signals in the range of 1 km or more. This achievement is very important because it can be more effective against terrorist attacks.

With the civilian conversion of military jammers and the development of all technology, it is good to know that the authorities are doing their utmost to protect the innocent. The woes can help with the terrorist attacks. The government’s defense measure is all the more important.

Don’t stay up all night

Now many young people have stayed up all night. Why? Because now there is a lot of entertainment. Mobile phones and wireless networks are particularly widespread. As long as there is a cell phone and WiFi network, many people can kill time very easily, including online chat, playing mobile games and so on.

In order to keep teenagers, so as not to stay late and protect their health, parents need to control their use of WiFi network and cell phone. How do you do that? Young people are very rebellious, it is difficult for them to listen to other opinions sometimes, especially for the children who are addicted to mobile games, it is difficult for them to leave the phone.

Once you play the phone, you will easily forget the time. So the phone is the main reason for their lack of sleep time. Lack of sleep will hurt your health and also have a bad impact on your learning and work. To live healthy, we need enough sleep. So we should get rid of the addiction of the cell phone. To do this, you can use the cell phone jammer at the right time to block the phone signal so that the phone cannot access the Internet.

Of course, we should pay attention to the WiFi network. Because of WiFi networks, even if there is no cell phone signal, you can also play the phone at midnight. The phone’s small screen is easy to hurt her eyes. So we need wifi jammer. To fufill both, you can choose a phone and WiFi jammer to interfere with cell phone signals and WiFi networks at the same time.

In a word, to let teenagers and get enough sleep and maintain a healthy lifestyle, sometimes we have to use jammer at the right time.

Cell phone jammers are used to combat trade in the Philippines

In the Philippines, as part of the campaign against human trafficking, government immigration officials used mobile jammers at Ninoy Aquino International Airport (NAIA).

Immigration said it plans to install high-performance jammers in all of the country’s international airports.

Cell Phone Blocker

Immigration chief Ronaldo Ledesma said the jammer was a tool to help curb airport traffic.

Ledesma added that the trafficking group connects cell phones to the intended victims.

An immigration official asked not to call it, he said: “The usual destination for traffickers is the travel visa for foreign Filipino workers, the so-called travelers.”

Immigration officials said how the gangs work “sometimes they are only with a few immigration officers at the airport and display the intended victim or victim of cell phones at a specific queue or counter.

The use of cell phone jammer is one of several measures undertaken by business intelligence and interinstitutional anti-trafficking programs, and it has been reported that there has been an increase in the number of Filipino trafficking cases.

Ledesma emphasized: “These mobile jammers will certainly strengthen our fight against human trafficking.”

He said that the office’s real estate department had been ordered to obtain the necessary licenses from the National

To receive the Telecommunications Commission (NTC) to operate the NAIA handsets again as soon as possible.

The Commission is a government agency under the Ministry of Justice that oversees the implementation of Act No. 9208 or the 2003 Anti-Trafficking Act.

John Tugade, head of the BI real estate department, said the jammers and their servers are still available in NAIA.
