With the development of science and technology, communication technology has also been upgraded. As a very advanced digital product today, mobile phones must have been very familiar to everyone, and almost everyone has one and is using it. It has become one of the indispensable tools in everyone's daily life and work.

The communication data transmission between mobile phones and base stations is to transmit signals directly to the base station. The base station is a signal jammer station in mobile communication technology. It is difficult for mobile phones to make voice calls, surf the Internet, pay and other services. Mobile phones play a very important role in our daily life, but it really doesn't work without base stations.

In fact, the emergence of anything has both good and bad. Mobile phones have played a very convenient role in our daily life, but they have also brought us some inevitable problems, such as not being able to use mobile phones in some specific occasions. In order to prevent the use of mobile phones in some special occasions, mobile phone signal jammers have emerged. Signal blocking equipment can effectively block the signal of mobile phones, so that mobile phones cannot be connected to base stations. At this time, the mobile phone will display a no service status.

Many people know one thing. The working principle of mobile phones is to establish a connection with base stations within a certain working frequency band to achieve data transmission such as video, voice and Internet access. When the mobile phone signal jammer works, it will scan the wireless channel from low frequency to high frequency at a certain speed. When the mobile phone receives the data signal from the base station, it will form noise interference on the screen, so that the mobile phone cannot establish contact with the base station, thereby achieving the purpose of shielding the mobile phone data signal. The shielding distance of the mobile phone signal jammer is closely related to the distance between the base stations, so the distance between them must be paid close attention.

When the place to be shielded is closer to the base station, the intensity of the mobile phone signal transmission will become stronger. The mobile phone signal jammer is difficult to shield, and at this time it is necessary to replace the mobile phone signal jammer with a higher power to shield the data signal. But when the shielding place avoids the base station, the mobile phone signal transmission intensity is weak. The signal strength of the mobile phone signal jammer does not need to be too large to be able to shield.

In general, the efficient shielding distance of the mobile phone signal jammer is closely related to the distribution and distance of the base stations near the shielding place. The closer the base station is to the shielding place, the less the shielding distance of the mobile phone signal jammer; the farther the base station is, the farther the shielding distance of the cell phone signal jammer is.
