Whether in public places or at home, people's lives are now inseparable from the Wi-Fi network. Not only do computers need to access the Internet, but many functions of smart phones also depend on the Internet. But what if you don't want to be disturbed by wifi? You only need to buy a wifi jammer, you can easily solve your problems. Let's take a look at topsignaljammer.com to explain what wifi jammer is and what wifi jammer does.
First of all, we need to know the frequency used by the wifi signal transmission device, usually between 2400 and 2500 MHz. The mobile phone or computer receives the signal and completes the communication. According to the above working principle, wifi jammer usually consists of power supply, electronic scanning control unit, segmented RF module unit, amplifier unit and transmitting antenna unit. The signal generator generates a sweep signal through the inverter, switches from the oscillator modulation to the mobile communication working frequency band, and then controls the power through the power amplifier amplification and the voltage regulator tube. The amplified frequency sweep signal is then transmitted through the air as radio waves. The scrambled signal forms scrambled interference in the message signal received from the mobile phone. The mobile phone cannot receive the normal data sent by the wifi device, which prevents it from establishing a normal connection with the wifi device. The mobile phone therefore cannot search for the network signal, service system, etc., and the blocking effect is achieved.
The jamming power of any signal jammer is fixed and the radius of protection of the unblocked space is determined by the path attenuation and the signal level of the receiving base station. In order for the WIFI jammer to interfere with the network signal, you must ensure that the signal field emitted by the jammer is greater than the signal strength of the mobile in the jamming area.The closer the jamming place is to the device transmitter, the better the effective jamming effect. The further away, the more serious the effective interference effect.
It can be seen that within a certain transmit power, the interference range depends on the field strength in the interference region. Regardless of the power shield, as long as the transmit power is constant, the increase in the power of the interference signal decreases and therefore decreases. Interference capacity.
The development of wireless networks for smart phones has a great effect on improving the speed of development. Mobile phones can solve network problems. Mobile phones play a more important role in people's lives, mobile communications and mobile Internet, among others. Because of this, it caused a lot of trouble, especially in the home network, children are addicted to the Internet, mainly because of the wifi network. As a result, many families are gradually starting to install mobile phone wifi screengear devices to block the network to control their child's online time.
Although the wireless network is convenient for accessing the Internet, the problems it causes cannot be ignored. This is not only a network access issue but also a network security issue. In order to maintain a good network environment, many places have started to install such wifi filter screen to protect network security in some places and prevent excessive network usage. This equipment has been widely used in various countries and regions around the world, typical representative of schools, prisons, libraries, reading rooms and gas stations.
