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?

① After networking, the mobile phone signal blocker can log in to the shield management system webpage to remotely turn on or off the mobile phone signal blocker with one click.

② The transmitting power of each channel can be adjusted remotely

③ The working status of the mobile phone signal blocker can be observed in real time, so that the user can see the working status of the current mobile phone signal blocker at a glance.

④ Later maintenance and repair is very convenient. Through the mask management system, you can judge the working status of the mobile phone signal blocker according to the color of the icon.

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.

GPS jamming requires very little jamming energy to temporarily or completely block the GPS signal.After all, gsm signal jammer and communication base stations are in competition.All normal microwave data signal data information released by the base station will inevitably prevent the mobile phone from establishing a connection with the communication base station, so as to achieve the purpose of intercepting the mobile phone signal.For this purpose, electromagnetic waves are emitted that completely or partially superimpose the signals and waves of the disturbed transmitter, rendering them unusable.If the signal strength of the mobile phone signal jammer is lower than the natural environment, the output power of the wireless channel transmitted by the Chinese communication base station to the mobile phone will not be intercepted by the signal jammer.

For example, in aviation or the military, special antennas are used that only receive signals from a certain direction.Statistics from the Criminal Police also prove that locating vehicles or trucks using GPS trackers installed in vehicles is an effective method of locating stolen vehicles, even if they have been taken abroad.In this regard, there is always a residual risk that GPS positioning will be corrupted by criminal energy to disable anti-theft protection or use the vehicle for unintended purposes.

Only when the output power of the signal jammer exceeds the transmission power of the communication base station to the mobile phone Only when the output power is output, the blocking can be stopped reasonably and effectively.Such transmitters have difficulty receiving radio signals correctly.Jammers can operate on the same or adjacent frequencies, the field strength of the jammer and the type of jamming wave are important.It is easy to understand that the frequency band released by the mobile phone signal jammer invades the frequency band of the mobile phone receiving communication base station.Because GPS satellites orbiting more than 20,000 kilometers above the Earth's surface have relatively low transmit power.Mobile Smart Positioning Devices Offer Special Protection Against GPS Interference Mobile Smart GPS Tracking Transmitters provide the option to continue locating the vehicle in the event of GPS interference.

Such signal blockers are used time and time again in criminal cases.In flight, co-targeting allows the weapon to use its advanced viewfinder to identify and pass on tactical details to other weapons so it can maneuver as needed.The Air Force is taking new steps to bring promising new technology to the weapons network in flight.Recent tests of a small-diameter synergistic bomb that transmits data in flight have shown promising results and room for improvement.The tracker supports so-called cell positioning (also known as GSM positioning or cell phone positioning) as an alternative.Car locks are also increasingly being manipulated by jammers to open vehicles and steal items from them.

If the entire vehicle is stolen, thieves use GPS jammers to block GPS signals over a wide area.10 times weakening; less weakening if it is sheet or glass material.How much a signal jammer can block is not only related to its own signal strength, but also to the spacing between the communication base stations in the natural environment used.This test rate will lead to the intrusion of the audio data signal received by the mobile phone with bit error, resulting in the mobile phone being unable to detect the slave communication.Even small GPS jammers can jam signals within a radius of about 10 meters.The perpetrator tries, for example, B.to overcome the anti-theft system in the case of shoplifting.

This means that it is no longer possible to GPS track the vehicle with a GPS tracker. The mobile signal jammer tests the high-end of the low-end frequency band of the wireless channel at a certain rate during the operation.The Air Force tested the ability of air-dropped bombs to share purpose-sensitive data with each other in flight to customize attack specifications, locate GPS interceptors, and optimize the speed and accuracy of attack maneuvers.GPS Jammers and Jammers - Still Using Smart Hardware Location A GPS jammer or GPS jammer is a device used to jam or completely block Global Positioning System (GPS) signals operated by the U.S.Department of Defense.Therefore, when all signal jammers are used in different data signal environments, the interception interval will be different, and the direction of the communication base station and the output power of the communication base station cannot be reversed.
