Many people know that the communication of the mobile phone is transmitted through the signal of the base station, and what the wireless wifi signal jammer does is to shield the base station signal in a certain frequency band.
The wireless signal jammer system is a complete system consisting of power module, power unit module, chassis, antennas with different gains and scientific design, installation and debugging technology, which can cover large-scale areas.
After the wireless wifi jammer is used, if you want to know how it works, it mainly depends on whether the mobile phone displays a signal.
Less than 100 square meters. For the more common small and medium-sized conference rooms, the internal environment is relatively transparent.
At present, every school examination room is basically equipped with a wireless wifi signal jammer. With its help, it is possible to maintain a stable order in the examination room and completely eliminate such bad things as cheating.
For all kinds of school examination rooms, supervision places, and secret-related units, wireless signal jammers are a very common device, because in some cases where mobile phones need to be shielded.
The network version of the wireless signal jammer is a new type of high-tech information security product developed on the basis of the original, using modern high-tech, through in-depth analysis of communication principles, and comprehensive comparison of electromagnetic emission suppression methods.
In the face of places that need to use multiple signal jammer devices, it is often inconvenient to manage. Due to the large number of blocker devices, the daily inspection workload is relatively large.
Check the selected wireless signal jammer technology. High-quality wireless signal jammers are made of high-quality materials from the housing to the internal components.
The wireless signal jammer system is a product that integrates signal shielding, monitoring and management. By shielding the downlink signal of the mobile phone, the illegal use of the mobile phone can be prohibited.
With the advanced technology in modern society, people's lives have entered a state of intelligence.
A friend of ours told us that he was always fidgeting in the library and hearing all kinds of voices, which seriously affected his reading, and people loved it because of the silent environment of the library.
As a substitute for the early mobile phone signal jammer, the mobile phone wireless wifi signal jammer product has completely surpassed the effect of only shielding the mobile phone signal.
Romania plans to implement a system to obscure cell phone reception in prisons starting in 2015, which will limit the use and frequency of cell phones in prisons.
Let's first look at how WiFi and Bluetooth work. Both WiFi and Bluetooth are wireless devices, and generally use the 2.4G frequency band to support short-distance data exchange.
Signal jammers, I believe students in the past few years know what they are, the most common radio interference equipment in the examination room.
In recent years, with the continuous development and popularization of communication tools such as mobile phones, and the continuous improvement of the technical level of mobile communication tools.
In order to prevent the internal information from being stolen by the outside world, which leads to the occurrence of leakage incidents, many technical preventive measures are adopted in secret places, and the installation of wireless wifi signal jammer is one of these technical preventive measures.
Wifi signal jammer, can it be shielded through the wall through the wall? To answer this question, several situations need to be considered.
The best operating principle of wifi signal jammer; the working principle of mobile communication is that within a certain frequency range, wireless devices (mobile phones, etc.) and signal towers communicate with signal towers through radio waves to complete data and sound transmission with a certain baud rate and modulation method.
To interfere with the signal of the entire teaching building, should you choose a low-power signal jammer or a high-power one?
Many users who use wireless wifi signal jammers do not understand its working principle, and often use it beyond the frequency range, resulting in poor use.
Now the wireless network is flooded, so the network will interfere with each other, resulting in poor wireless network at home, many people want to how to block the signal? Can a wifi signal blocker block local wireless signals?
As you know, actual working time will depend on signal interference strength and battery capacity. Signal interference strength depends on three factors:
So far, the main WiFi frequency bands used in China are: WiFi2.4G and WiFi5G, of which WiFi5G is further divided into WiFi5.1G and WiFi5.8G.
In major electronic forums and social platforms, there will always be posts of this kind explaining how to crack the wifi signal jammer.
Many customers called and said that I needed a wifi frequency jammer with a radius of 50 meters, a distance of 500 meters, and a radius of one kilometer, and the three networks of China Mobile.
A signal jammer is a device with a very broad name. Different shields can shield different signals, mainly depending on the needs of customers. For example, there are remote control cheating signal jammers, walkie-talkie signal jammers.
The test signal jammer has a radius of about 1.3 kilometers, which may have an impact. The mobile phone signal shielding device uses the latest Israeli interference technology to generate stable electromagnetic signals, covering mobile communication GSM.
Afraid of incomplete shielding? The signal environment is complex, afraid of insufficient budget? Afraid of being destroyed, the machine life is short? Just want to block one kind of signal, afraid of affecting other frequency bands?
In various examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military centers, libraries, theaters and other places, in some cases, the use of communication equipment such as mobile phones is prohibited
First, let's talk about the current status of the use of wireless signal jammers.1. The area that should be shielded is not strictly shielded, and it costs money and effort to be ineffective;
