What functions can the mobile phone signal blocker achieve after networking?

In some classified places, if you carry mobile communication equipment, there is the possibility of leakage, causing harm to units or individuals. What is more serious is that some criminals use mobile communication equipment to remote control bombs, causing casualties and property losses. To solve these problems, the mobile phone signal blocker came into being. It can interfere with the signal of mobile communication devices, and then cannot use mobile phones to communicate normally. Provide security and stability for meeting rooms, prisons and other places!

With the development of society and the progress of science and technology, the requirements for mobile phone signal blockers are also constantly improving, and more and more intelligent. Now the mobile phone signal blocker has a networking setting, then relative to the ordinary mobile phone signal blocker, what are the functions of the intelligent network control mobile phone signal blocker?

Utilizes of Signal Jammers

Why are cell phone jammer increasingly used in school testing rooms?

Cell phone blockers are used in many places. Mobile phone signal blockers can now be seen in exam rooms of major schools. So why are more and more schools looking to install them? This is because cheating has become more rampant in recent years. In order to effectively curb the occurrence of this kind of cheating, the mobile phone signal blocker came into being. The appearance of mobile phone signal blockers is a great help to the examination room. More and more people choose it to prevent mobile phone communication cheating.

Wireless blockers: Block cell phone signals in certain areas

Common wireless blockers block cell phone signals by transmitting interference signals. By transmitting a signal of a specific frequency, the surrounding electromagnetic environment is subject to the same frequency interference, and the mobile phone cannot correctly analyze the signal from the base station, so as to achieve the purpose of shielding the mobile phone signal.

Under normal circumstances, when the mobile phone first enters a cell, the local cell signal base station will update the location of the mobile phone and assign it new temporary user information. After receiving the base station information, the mobile phone can determine the location of the cell. When the wireless wifi jammers is working, it sends a interference signal and interferes with the effective signal on the base station broadcast channel frequency band. Interference signals increase the bit error rate of the communication channel and reduce the signal-to-noise ratio of the channel, which affects the effective reception of the broadcast information of the base station by the mobile phone. When the signal-to-noise ratio drops to a certain extent, the mobile phone cannot decode the broadcast information of the base station normally, thus losing contact with the base station. After many attempts, the mobile phone cannot determine the service area it is in, so there is no signal in the interfered mobile phone area. Not in the service area.

How to ensure the signal interference to achieve the desired effect

Wireless shielding is usually used in examination rooms, regulatory places, confidential meeting rooms, etc. When using wireless shielding in these places, it is necessary to ensure that the shielding effect of wireless shielding achieves the desired effect. In fact, there are many factors that affect the shielding effect of wireless jammers, such as the distance between the installation site of the wireless jammer and the nearby signal base station, the transmission power of the jammer, and the use of the wall. In order to ensure that wireless blockers can effectively block mobile phone signals, it is very important to test when buying a GPS jammers.

First, test the shielding distance of the wireless blocker, not just one or two network types of the phone. The mobile phone network used by cheating candidates during the exam is different, especially the 5G mobile phone network which is very popular in the past two years. Therefore, it is necessary to test mobile phones on all networks of current carriers. Make sure that the wireless blocker can block all cell phone networks in the exam room area to qualify!

Then test the stability of the shielding effect of the wireless shield. Test the shielding effect after turning on the phone to ensure that the phone has no signal, and the mobile phone signal cannot appear from time to time, otherwise it will lead to someone using this interval to send test information. This is enough time for the examinee to cheat through the answers. Therefore, when purchasing a wireless jammer, we must pay attention to the field test of the shielding effect of different mobile phones to ensure that the jammer really achieves an effective shielding effect.

Why is the wireless signal blocker used in the exam room with a built-in antenna?

In recent years, as long as there are large exams, in order to completely eliminate cheating in the exam room, it is not surprising to install wireless signal blockers. However, many people have only heard of such things, and know that it is used to block signals, and have not carefully observed its appearance. So, what does a wifi jammer look like? The difference between wireless signal blockers first lies in the appearance of the housing. There are currently two types on the market. One uses an external antenna, the other an internal antenna. The internal structure of these two wireless signal blockers is still a little different.

Wireless signal blockers with built-in antennas usually have the antenna installed inside, and the antenna is composed of various electronic components. With a built-in antenna like this one, the main reason is aesthetics. The external antenna shielding device is provided with a plurality of interfaces on the housing for mounting the external antenna. These interfaces represent signal shielding for different channels. Generally speaking, the number of external antennas also determines the advantages and disadvantages of wireless signal blockers. More antenna shielding will also have a wider range. It’s got all kinds of electronics in it. Through these electronic components, the purpose of interfering with mobile phone signals can be achieved.

Cell Phone and WiFi Jammers

The range of cellular and wifi jammers may vary depending on their power and surroundings. It can block signals from many different types of networks at the same time. Low-powered devices can only jam signals up to 30 feet away, while high-powered jammers can make cell-free areas the size of football fields. Law enforcement jammers can shut down service for up to a mile. These devices can be placed in many places, depending on your needs.

One of the reasons people use cell phone and wifi jammer is to prevent people from using their smartphones and social media without their permission. However, some have reported that their neighbors use jammers to prevent their teenage children from accessing the Internet without their permission.

Cell phone and wifi jammers work by blocking radio and cell phone signals. It interferes with these signals and blocks their reception. These devices block signals from cell phone towers, cutting out all but the most important signals. So, cell phone jammer blocks calls and text messages. The phone will not display the signal bar. It will stop responding to calls and won’t even register calls. Therefore, people who buy mobile phones and wifi jammers will be protected from harassment or even harm by others.

Jamming Cell Phone Signal

1. Jamming cell phone signals is a multi-billion dollar industry. Many people have tried this approach with varying degrees of success. A jammer is a device that covers an area, denying service to everyone. Some have even suggested disrupting movie theaters, highways and school systems to prevent emergency services from reaching those areas. However, these methods are controversial because some countries do not regulate them.
2. A Tampa Bay-area school used a cell phone jammer during a recent incident, but officials are cautious about the device’s effectiveness. While it’s illegal to use cellphones in schools, a Florida principal is using cell phone jammers in his classroom.

Many people use cell phone blockers to protect themselves from rude passengers. The technology sells for less than $200. Plus, it’s easy to install. You can choose a jammer based on the area you plan to use. While it won’t block all signals, you can choose a specific location for your device.

Uses of mobile phone jammers

The popularity of mobile phones is increasing day by day, and many people now own multiple mobile phones for various purposes. Few people live without a cell phone, and cell phone use has become so common that a phone jammer is the perfect tool for blocking cell phone signals. Phone jammer work by jamming cell phone signals, blocking them within a 60-80 foot radius.

In restaurants and movie theaters, callers are an unwelcome distraction. They keep other people from concentrating on the meal they’re eating or watching a movie. But with cell phone jammer, people can focus on the meeting. In addition to blocking cell phone signals, phone jammers allow people to focus on the meeting at hand, allowing everyone to fully participate in the meeting.

Cell phone jammers are available in a variety of styles. Some are personal cell phones, while others resemble routers with multiple antennas. Personal ones can create bubbles up to 30 feet, while stronger ones can block cell phone service for up to a mile. They are especially useful when police need to monitor a presidential motorcade, or when terrorists are plotting to detonate bombs at a distance.

Advantages and disadvantages of cell phone jammers

• There are people who make and sell cell phone jammers. The federal government has even fined some companies for using illegal equipment in violation of federal law. While these companies were fined, they cooperated with the FCC and their fines were reduced. However, using a cell phone jammer is not without its drawbacks. First of all, if you buy a cell phone jammer, you will most likely interrupt someone’s voice or text message.
• The main disadvantage of cell phone jammers is that they are very difficult to detect. If you are caught using a cell phone jammer, your signal reception will be poor.
