What is the function of wifi jammer?

Whether in public places or at home, people's lives are now inseparable from Wi-Fi networks. Not only computers need to go online, but many functions of smart phones also rely 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 problem. Let's take a look at topsignaljammer 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 equipment, which is generally between 2400-2500MHz. The mobile phone or computer receives the signal and completes the communication. According to the above working principle, a wifi jammer is usually composed of a power supply, an electronic scanning control unit, a segmented radio frequency module unit, an amplifier unit and a transmitting antenna unit. The signal generator generates the scanning signal through the inverter, switches from the modulation of the oscillator to the working frequency band of the mobile communication, and then controls the power through the amplification of the power amplifier and the voltage regulator tube. The amplified frequency sweep signal is then transmitted into the air in the form of radio waves. The scrambled signal forms a scrambled interference in the message signal received from the mobile phone. The mobile phone cannot receive the normal data sent by the wifi device, resulting in the inability to establish a normal connection with the wifi device. Therefore, the mobile phone cannot search for the signal of the network, service system, etc., so as to obtain the shielding effect.

The interference power of any signal jammer is fixed, and the protection radius of the unobstructed space is determined by the path attenuation and the signal level of the receiving base station. For WIFI interference to interference with network signals, it is necessary to ensure that the signal field emitted by the interference is closer to the area. The interference position is to the device transmitter, the better and effective than the signal strength of the interfering mobile station. Interference effect. The farther the distance, the more serious the effective interference effect.

It can be seen that within a certain transmission power, the interference range depends on the field strength of the interference area and has nothing to do with the power shielding. As long as the transmission power remains the same, the increase of the interference signal power will decrease and therefore decrease. Interference ability.

The development of smart phone wireless networks plays an important role in increasing the speed of development. Mobile phones can solve network problems. Mobile phones are playing an increasingly important role in people's lives, mobile communications and mobile Internet. Because of this, it has 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 have gradually begun to install screengear wifi devices for their mobile phones to shield the network and control the children's online time.

Although wireless networks are convenient for surfing the Internet, the problems they bring 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 begun to install such wifi filters to protect the network security in some places and prevent excessive use of the network. The equipment has been widely used in various countries and regions in the world, typical schools, prisons, libraries, reading rooms and gas stations.
