WIFI Jammers
The development of smart phone wireless network plays an important role in improving the speed of development. Mobile phones can solve network problems, and mobile phones play a more important role in people's life, mobile communication and mobile Internet. Because of this, it caused a lot of problems. Especially in the home network, children are addicted to the network mainly because of the WIFI network. Therefore, many families gradually began to install mobile WIFI jammer to block the wlan network to control their children's Internet time.
What is a WiFi Jammer?
The WI FI signal jammer transmits on the same frequency as the signal to be jammed. If the jammer sends a significantly stronger signal, it renders the original signal unusable -- Make the wireless network generator unable to send out signals, so as to achieve the purpose of jam.
In a WLAN, this means that the exchange of packets only works to a limited extent or doesn't work at all, and the actual data flow can no longer be properly grouped together. This is a key point for security-related mission devices that need to be protected from hacking.
However, WiFi jaming are perfectly normal in radio technology. In the 21th century, when the number of transmitters increased substantially, need poorly shielded transmission signal caused interference with radio signals. But even today, WLAN networks that transmit close to each other on the same radio channel sometimes interfere with each other. However, the problem was not so severe that all data traffic stopped.
Why Do You Need A WIFI Jamming Device?
We often encounter children who delay learning because they are addicted to games, and the existence of wifi further contributes to this phenomenon. Imagine that your child uses a mobile phone/computer to connect to the wifi signal to surf the Internet wantonly, and stays up all night to watch Internet TV series on the mobile phone, which will lead to the lack of energy in class during the day, and thus the academic performance will drop.
To prevent this from happening, you can buy a wifi blocker device, it can block the signal from the wifi router and won't interfere with the cell phone signal, you can still use your phone to make calls, using a wifi jammer allows you to It can prevent children from being addicted to the Internet; not only that, the wifi jammer can also interfere with the bluetooth signal, and can also interfere with the bluetooth candid camera, protecting your privacy.
Blocking WI FI Bluetooth Signal Device
Bluetooth and Wi-Fi technologies are two of the most popular wireless communication technologies. However, these devices are also being used more and more often, which creates some signal confusion issues. In order to solve these problems, some people use disruptor to interfere with the transmission of wireless signals.
First, let's take a look at how Bluetooth and Wi-Fi work. Both Bluetooth and Wi-Fi are wireless communication technologies that transmit data through wireless signals. Bluetooth technology is suitable for short-distance communication and is usually used to connect mobile phones, headsets, mice and other devices. The Wi-Fi technology is suitable for medium and short-distance communication, and is usually used to connect to a wireless router to realize wireless access to the Internet.
However, the transmission of Bluetooth and Wi-Fi signals is limited. The distance and bandwidth of signal transmission will be affected by the physical environment and interference. If there is interference during signal transmission, it will affect the communication quality. In some scenarios, the blocking problem becomes particularly prominent. For example, in public places, crowded with people, signal blocking is easy to occur. At this time, some people will resort to jammers to solve these problems.
Bluetooth Signal Scrambler can interfere with signals in different bands. Some low-end disruptor can only jam one band, while some high-end blocker can jam multiple frequency bands. Using internet jammers can cause serious interference to normal wireless devices. If you are using a Bluetooth device or a Wi-Fi device, you will not be able to use them properly when the scrambler's signal interferes with your device.
Will the WI FI Bluetooth jammer jamming with the WIFI signal and will affect the cell phone signal at the same time?
The bands used by WiFi signals are 2400-2500MHz, 5125-5350MHz, 5725-5850MHz; the bands used by mobile phone communication signals are 5G: 617-685MHz, 3400-3600MHz, 3600-3900MHz; 4G: 2300-2400-2400MHz, 700-803MHz ;3G: 2110-2180MHz; CDMA/RC868: 850-894MHz, it can be seen from the above signal bands that the WiFi signal does not overlap with the cell phone signal , so the WiFi blocker will not interfere with the mobile phone signal when it is running.
Of course, if you want to blocking with WiFi and mobile phone signals at the same time, it is also possible. The current Wi Fi jammer design is very advanced. It can set both Wi-Fi and mobile phone signal into the WiFi signal device at the same time. When it is running, turn on the desired signal. If you want to interfere with mobile phone and WiFi signals at the same time, you only need to open all the bands to complete the interference.
Wifi Blocker Signal Bands
To jamming with the WIFI signal, you can buy a special WIFI signal jammer, and choose different jammers according to the frequency of the used.
At present, the WiFi bands on the market are 2.4G, 5.1G, and 5.8G, of which 2.4G and 5.8G are the most used bands, the most used signal of 5G WiFi is 5.8G, and a small part uses 5.1G.
1. There are special WIFI signal blocker that only shield 2.4G WIFI. Most routers use 2.4G signal.
2. The dual-band switching router, which uses 2.4G and 5.8G frequencies, so at this time you need to buy 2.4G and 5.8G WiFi scrambler. Of course, the 5.1G WiFi interference can also be increased, as long as you have needs, we can serve you.
3.The shielding range of WiFi jammers in different bands is also different. Under the same use environment and the same transmit power of the jammer module, the shielding range of WiFi2.4G is larger than that of WiFi5G. This is because the lower the frequency, the farther the wireless signal can travel, and the less the attenuation will be.
Therefore, according to different use environments and WiFi shielding of different bands, choose the appropriate WiFi blocker to achieve higher cost performance.
These Wi-Fi interceptors are actually very simple to operate and it sends the same frequency signal as WiFi to interfere with WiFi signals. You just need to be sure you know the correct type of frequency that is being used here. In this case it is 2.4 GHz.
