The prison service has requested the installation of a signal jammer

Due to concerns about the ineffective jammers installed in the Rajasthan Central Prison and the use of cell phones by inmates, the State Prison Service asked the Home Office to transfer the total income of the three prisons from ‘worth Rs 2012 for best results.

Not only is the government struggling to restrict phone use, prison security is also affected. The High Court also takes these matters seriously. The prison official added in a letter to the government: “In order to prevent the prisoners from using the telephone and to better interfere, we ask you to approve the transfer of these 57 jammers to the two central prisons of Bikaner and Bharatpur. And “Ajmer”.

The prison department has requested a budget of Rs 7,200,100 for the transfer of the jammer, Rs. 1.12 million for the new tower, and Rs. 188 crore for the annual maintenance of the equipment.

As we all know, mobile phone signal jammers are very common. People will choose to buy mobile phone signal jammers to maintain their privacy and protect their independent space. Where will the jammers be used?

armband mobile gps jamming

Cell phone jammer is mainly used in various places where cell phone use is prohibited, such as various inspection rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals , governments, finances, prisons, public security and military might.

It is understandable that the WiFi cell phone signal jammers in the market can limit cell phone signals that are 500 meters from the transmitting station and have a radius of> 20 meters. The shielding radius is adjustable, it only protects the cellphone signal without affecting other electronic devices. Save energy, the power is 20W-480w.

The mobile phone is in a certain frequency range when it is operating. The mobile phone and the base station are connected by radio waves, and the data and sound transmission is supplemented by a certain baud rate and modulation method. Taking this communication principle into account, the mobile phone jammer will sweep the frequency from the low to the top of the front channel at a certain speed during the working process. The mobile phone seems to search the network, there is no signal, no service system and other phenomena.
The signal jammer is very convenient and practical, you don’t have to worry about whether it will be difficult to use.

About the need to use interfering devices in public places

Many people don’t think installing cell phone jammer in schools is a solution, but because children have access to the internet in several other places, such as at home or in open Wi-Fi areas in the city. It’s a very good plan. Adolescents do not have enough maturity to use the Internet properly. From time to time, out of curiosity or under pressure from peers, they may come into contact with content they shouldn’t have. Even if someone accidentally makes such a mistake, it is a very good idea to install jamming devices.

Apart from basketball, what makes me more happy than sports is being able to watch movies in the theater. This is a rare hour and a half for me to get away from the real world and immerse myself in the fantasy of others. Using a mobile phone in the theater is distracting. Like a drunken fan of sports games, it’s distracting. If you look carefully, a nearby ringing phone suddenly interrupts your thoughts, which is terrible.

If you’re attending an emergency meeting and don’t want to join unwanted calls or messages during an important meeting, you can take advantage of mobile phone signal interference technology. Using 3G / 4G Phone Jammer, this technology allows people to avoid calls and text messages without turning off the phone. When this technology is enabled, the signal from the base station will be blocked directly and you will not be able to communicate with others via your mobile phone.

I heard that some devices can prevent eavesdropping and this is true

There are equipment to prevent eavesdropping

More precisely, this is a technique called “scrambling”, namely jammers and jammers. With the popularity of mobile phones, this interference has become popular among the public.

Interference is a device that interferes with radio waves used in communication devices such as mobile phones. When this kind of interference occurs, it interferes with radio waves emitted by mobile phones at a certain distance from the device.

Places that are susceptible to interference include concert halls, movie theaters and hospitals where the use of mobile phones is restricted.

Recently, signal jammer has been installed around bank ATM machines, which are often used to prevent transfer fraud. Many people may be familiar with this news.

Moreover, this interference is an effective preventive measure to prevent the use of radio waves for eavesdropping.

Interference can also prevent eavesdropping

You can use scrambling to block listening. Several scramblers are commercially available and can be purchased by the public.

Jammers can be divided into two types.

Types of blocking/blocking radio waves

Types of hard to hear

There are two types of phone scramblers: one that blocks radio waves and causes interference, and one that makes speech difficult to understand. You can use any of them to stop eavesdropping.

You can use a single encryption machine the same size as the apartment room to protect your privacy, so as not to be eavesdropped. Therefore, it can be expected to be an inexpensive method to prevent eavesdropping.

However, this method of preventing interference requires some precautions to be kept in mind.

Notes on using interference

Cannot completely prevent interception

There are two types of scramblers, but neither can completely interfere with listening.

The performance of 3G/4G mobile phone jammers that the general public can buy is very limited, and the type of blocking/blocking radio waves can interfere with radio waves up to 2.4Ghz, but cannot block radio waves beyond this range.

Also, the type of sound that is hard to hear does not mean that you can mute it by completely muting your voice, as the name implies.

You may need a license to use the scrambled device

Some models send mobile phone interference signals. This powerful interference radio can only be used with the permission of a third-level professional terrestrial radio technician.

If used by an undocumented person with interference model qualifications, a violation of the Radio Law will result in severe penalties.

Even if you block the interception of spies, it will interfere with the communication of the phone, so it is difficult to hear or hear the communication with the phone. There is a danger of touching people.

You will not be caught in commercial facilities or public transportation

Blocking commercial facilities or public transportation violates the Radio Law.

Even if it is unethical to use a mobile phone on a bus or train, do not bring the jammer into the car, but only use it as a jam avoidance device.

In order to prevent eavesdropping, there are plans to install interference in the home or office, but there are restrictions where interference can be installed and where interference can be used.

Jammer-mart’s mobile phone signal jammer is recognized by consumers

Many friends who use mobile phones have this kind of distress, that is, the signal of the mobile phone often has problems. Especially friends whose home is in the country, can’t chat online all day long. But after some friends used Saiyue Communication’s cell phone jammer, this problem was completely solved.

Whether it is a branded mobile phone or a copycat mobile phone, they often encounter poor signal problems. The cell phone signal booster of Saiyue Communication was born under this situation. This is a cross-age product, so it is very popular in sales. Whether online or in physical stores, many consumers are buying.

But at the same time, there are also many companies that seize the tricks and follow the trend, all of which are producing mobile phone signal amplifiers. This is because with the increase in mobile phone users, mobile phone signals have received serious interference. Because Saiyue Communication itself is a well-known company specializing in the production of mobile phone signal amplifiers. Now everyone in the industry knows that if you want to have a good mobile phone signal amplifier, you must choose Saiyue Communication. This is a testimony of strength, and also the affirmation of industry insiders and consumers.

Mobile phone shielding device selection guide for examination rooms

By the annual exam season, all parties have begun to prepare for the exam, and the invigilator has various tricks to prevent high-tech fraud. Among them, the shielding device used in the examination room is still an anti-fraud shielding device. However, Chengdu Saiyue Communication reminds that there are many types of shielding devices, and users should clarify their needs before purchasing them to avoid test room accidents due to poor shielding effects, and pay attention to the correctness of the method of use.

First of all, I want to clarify the place of use. Most schools use test room-type mobile phone shields that are suitable for long-term work and are durable. The second is how big are we in the shielded area? For example, if it is a room of 100 square meters or a venue of thousands of square meters, if the area is large, the power must be larger, and if the area is small, the shielding power must be considered small. Then there is which frequency bands need to be shielded. Are all China Mobile, China Unicom, Telecom and CDMA shielded? Still only need to shield part of the frequency band.

Phone Wifi signal jammer

At this time, we remind everyone that if you want to buy a suitable shielding device to achieve the effect, it depends on the method used. The main points are as follows:

1. It is recommended that the indoor shielding device be placed at a height of about 180cm-220cm above the ground, with a forward angle.

2. Whether there are obstructions (such as walls, metal products, etc.) between the wireless jammer and wireless communication equipment (mobile phones, etc.). The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to avoid it.

3. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shielding device.

4. The farther the jammer application environment is from the signal tower, the stronger the theoretical shielding effect of the jammer.

Install Cell Phone Jammers To Avoid Road Accidents

This is a question you should consider today. You may ask me: why should I worry about this? In response to your question, I would like to say that despite the fact that it doesn’t seem like a problem (for example, in relation to texting while driving), this topic is more and more popular these days. That is why I ask you to think deeply and consider various options. You also provide cell phone signal jammer to choose from.

Powerful signal jammer device

There is no law against texting while walking. But a town called Fort Lee in New Jersey almost passed such a law. Ultimately, the law was not approved and a few state walking safety programs were launched in March, as two fatal pedestrian crashes occurred in Fort Lee within 24 hours of February this year. . In addition, 117 pedestrians were fined for using crosswalks without using or using a cell phone.

Whether you are driving or crossing the road (or using a crosswalk), texting while driving or walking will not only put your life at risk, but the lives of others around you as well. For example, you text when going to the crosswalk, but you don’t see red lights and green cars. You start to cross the road, or you are hit by a car (especially if the driver is also texting and can’t see you), or the driver will apply hard braking and be hit by a car driving behind them. Or realize that he won’t be able to stop in time and is ready to stop his car from hitting you, he will turn to the sidewalk to take more time to rest. And no one knows how it will end … I suggest installing cell phone jammer around traffic lights, in order to eliminate the danger of looking at the phone.

To solve this problem, different countries use different methods. For example, in London, for pedestrians texting while walking, they would see loads on the poles, and when they hit the poles, they wouldn’t take much damage. Does that sound funny? Yep, it’s fun watching someone in that situation, but when you hit that post with your head, it’s definitely not that fun. However, for all pedestrians, including you, there is another option – you can prevent texting while walking and make your life and that of many people around you safer.

UAV signal race-the importance of jamming technology

With the rapid development of the drone industry, some individuals and groups have begun to use drones for malicious purposes on a global scale. Many companies are paying attention to this trend and trying to enter the anti-drone industry. They introduced various drone guns, anti-drone shooting, attacking birds, cyber artillery, lasers, missiles, GPS jammers, radio transmitters and more.

The drone did not seem to hit the projectile and laser when it landed (although this kind of evidence will definitely change this analysis). In addition to physical projectiles, there are three known non-dynamic methods to stop drones. Radio frequency (RF) interference, global navigation satellite system (GNSS) interference and deception. Radio frequency jammer disrupts the communication between the drone and its operator, usually causing the drone to descend or return home. With GNSS, the drone will lose its link with the satellite navigation. After that, the drone will usually hover, land or return to its original position. The attacker used deception to provide new information to the drone to control its flight.

By the way, the operation on the Crimean Peninsula was a great success, without bloodshed, because all Ukrainian military communications were cut off. I’m not sure about the mobile phone, but it is not allowed to use it as a military communication channel. Therefore, the Ukrainian army did not resist because it did not receive an order from Kiev. They don’t need much… Many people just joined the Russian army and navy enthusiastically.

It did not “close” anything. First, it will cause a big sensation on the radar oscilloscope, until the software or personnel press the “search for interference” mode button. Then lock the weapon system on the jammer. In a real war, the jammer will disappear within a few seconds. The American ship did not want this to be a fierce war, so it made the destroyer think it was evacuating it. You’re welcome.

China will continue to develop features designed to limit or prevent the enemy’s use of space-based assets in crises and conflicts, including the development of directed energy weapons and satellite interference.

The problem is that many potential enemies, including the Chinese and Russians, are developing advanced digital radio frequency memory (DRFM) jammers. These jammers effectively remember the incoming radar signal and repeatedly send it back to the sender. This will greatly reduce the performance of Friend Trader.

Can the test signal blocker block all communication signals?

Can the signal blocker block all communication signals? Having said that, many people are a little unfamiliar with test signal jammers. In fact, it has been widely used in the college entrance examination room. In the college entrance examination last year, many examination rooms were equipped with this kind of equipment. The response was very good. Practice has proved that this method has a good effect on eliminating electronic signal cheating. Starting this year, it has been vigorously promoted to allow more examination rooms to be equipped with this shield.

The emergence of shielding devices now solves many hidden dangers that disrupt the order of the examination room, allowing candidates to take the exam in a fair environment. The principle of the test signal shielding device is to disable the communication signal of the mobile phone by isolating the electronic signal, thereby preventing the use of the mobile phone to cheat. Not only that, it also has a good shielding effect on WIFI2.4G signals. Generally speaking, the effective range is within a radius of 0 to 30 meters. Generally speaking, a low-power test signal shielding device is sufficient to cover the entire classroom. It satisfies the test room’s requirement for shielding signals. Since the battery life of the device is generally three hours, although the heat dissipation is not good, it also leads to a particularly high cost performance, which is especially suitable for schools to buy test room signal shielding. Worry about buying test signal jammers is a common problem for many customers. At this time, you can contact Shankino and ask about the price of the test signal jammer. It is a manufacturer with many years of high quality and rich experience in research and development of shielding devices. With a first-class technical team to provide technical support for product quality, it is favored and selected by customers.
