Due to the need to limit the use of mobile phones in many occasions, installing frequency jammers has become the most effective way to solve this problem. However, users like some schools, prisons, detention centers, etc., their needs for frequency jammers are large-scale, and they often need dozens or even hundreds of them. So how to control and manage the large number of shielding devices in a unified way promotes the synchronous development of the frequency jammer control system. Nowadays, several shielding devices with remote unified centralized management function can also be seen on the market. After comparing the product functions and support performance, the question arises. Why do the control systems of frequency jammers mostly adopt the transmission method of wired connection?

In the current control systems of common frequency jammers, the networking methods of multiple shielding devices are almost all connected by wired connection. The wired connection here refers to the conventional network cable networked with the TCP/IP protocol, or the 485 serial port. Multi-core cable for protocol networking. There is another way, which is in the form of power carrier, by means of the power line that supplies power to the frequency jammer, and also transmits the control system while supplying power. But no matter which of the above methods, their communication network is actually through wired connection. So some customers thought: Wired connection must require construction wiring, so is it possible to use relatively mature wireless networking technology to control several frequency jammers online?

Although the biggest advantage of wireless networking is that there is no need to arrange dedicated communication cables, the communication frequency band used in wireless networking is precisely the communication frequency band that needs to be shielded or interfered most during the use of our frequency jammers, such as 433MHz. And WiFi2.4G, 5.8G, etc., if the wireless connection method is used to realize the network of the frequency jammer control system, this will cause a very embarrassing result: when the administrator remotely turns on the frequency jammer through the software, it has not been shielded at this time. Signal, turning on the equipment in the system can be realized normally, but once the shielding device is turned on, the wireless communication signal will be interfered by the shielding signal, which will cause the management personnel to send and transmit the next control command. , the signal cannot be reached or the transmission distance is severely shortened. This also makes the entire frequency jammer control system function unstable.
