Why do most control systems of mobile phone signal jammers use wired transmission?

In order to meet the needs of restricting the use of mobile phones in various scenarios, installing a mobile phone jammer is an effective solution. However, for users such as schools, prisons, and detention centers who need a large number of mobile phone jammers (often dozens or even hundreds of them), unified management and control of these devices has given rise to the development of mobile phone jammer control systems. At present, there are many control systems with remote centralized management functions on the market. When comparing the functions and supporting performance of these products, one can’t help but wonder: Why do most mobile phone jammer control systems mainly use wired connections for transmission?

In the existing mobile Cell Phone Jammer control systems, the networking method of multiple devices mainly uses wired connections. The common method is to use multi-core cables for serial port protocol networking; another method is to use power lines to High Power Jammers, and use power carrier technology to transmit control signals while powering. But no matter which method is used, the communication networks in these systems rely on wired connections. As a result, some customers began to think about whether they can use mature wireless network technology to achieve remote control of multiple mobile phone signal jammers, eliminating the construction and wiring work of wired connections.

Although wireless networks have the advantage of not requiring dedicated communication cables, the communication frequency bands used by wireless networks happen to be the frequency bands that mobile phone signal jammers need to shield or interfere with, such as 433MHz, WiFi 2.4GHz, 5.8GHz, etc. If a wireless method is used to establish a mobile phone signal jammer control system network, an embarrassing situation will arise. When the manager remotely starts the mobile phone signal jammer through the software, the devices in the system can be turned on normally because the signal has not been shielded. However, once the signal jammer is started and sends out a shielding signal, it will interfere with the wireless communication signal, causing the subsequent control commands of the manager to be unable to be transmitted normally, the signal may not reach the destination or the transmission distance is severely limited, resulting in instability of the entire mobile phone signal jammer control system.

Considering the various factors that lead to unstable signal transmission, the control systems of most mobile phone signal jammers rely on wired connections and networks.
