Why do the control systems of mobile phone jammers mostly adopt the transmission method of wired connection?
Due to the need to limit the use of mobile phones in many occasions, installing a cell phone blocker has become the most effective way to solve this problem. However, users like some schools, prisons, detention centers, etc., their demand for mobile phone jammers is 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 has prompted the synchronous development of the mobile phone shielding device control system. Nowadays, several shielding devices with remote unified centralized management function can be seen on the market. After comparing the product functions and supporting performance, the question arises. Why do the control systems of mobile phone shielding devices mostly adopt the transmission method of wired connection?
At present, in the control system of the current common mobile phone shielding device, the networking mode of multiple shielding devices is almost all connected through wired connection. Multi-core cable for serial protocol networking. In addition, there is another way, which is in the form of power carrier, by means of the power line that supplies power to the mobile phone 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 think: Wired connection must require construction and wiring, so is it possible to use relatively mature wireless networking technology to control several mobile phone 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 with the most during the use of our mobile phone jammer, such as 433MHz and WiFi 2.4G, 5.8G, etc., if the wireless connection is used to realize the networking of the control system of the mobile phone jammer, this will cause a very embarrassing result: when the manager remotely opens the phone jammer through the software, because at this time If the signal is not shielded yet, it is normal to turn on the equipment in the system, but once the shielded device is turned on, the wireless communication signal will be interfered by the shielded signal, which will cause the management personnel to carry out the next control command. When sending and transmitting, the signal cannot be reached or the transmission distance is severely shortened. This will also make the whole set of mobile phone jammer control system unstable.
Because of the factors that cause unstable signal transmission analyzed above, most of the control systems used in mobile phone jammers can only use wired connection and networking.
