In many situations, there is a need to restrict the use of cell phones. As a result, installing cell phone jammers has become the most effective solution to this problem. However, for users such as schools, prisons, and detention centers, the demand for cell phone jammers is on a large scale. They often require dozens or even hundreds of devices. This has prompted the synchronous development of control systems for cell phone jammers.
Unified Control and Management:
Many occasions require the restriction of cell phone use, making the installation of cell phone jammers the most effective solution. However, for users such as schools, prisons, and detention centers, the demand for cell phone jammers is on a large scale, often requiring dozens or even hundreds of devices. Therefore, the question arises of how to unify the control and management of these numerous jamming devices, which has led to the synchronous development of control systems for cell phone jammers.
Currently, several models of jamming devices with remote centralized management capabilities can be found on the market. After comparing the product features and support performance, a question arises: why do most control systems for cell phone jammers use wired connections? The common control systems for cell phone jammers on the market almost always use wired connections for networking multiple devices. This wired connection refers to the use of conventional network cables that form a TCP/IP protocol network or multi-core cables that form a 485 serial port protocol network. Another method involves power line carrier technology, which utilizes the power lines that supply power to the cell phone jammers to transmit control signals. However, regardless of the method used, their communication networks are ultimately established through wired connections.
Wireless Networking Challenges:
Customers have wondered if it is possible to use mature wireless networking technology to connect multiple cell phone jammers for unified control. Although the biggest advantage of wireless networking is the absence of dedicated communication cables, the communication frequencies used in wireless networking are precisely the frequencies that cell phone jammers need to block or interfere with, such as 433MHz, WiFi 2.4G, and 5.8G. If wireless connections are used to establish the control system network for cell phone jammers, an awkward situation arises. When administrators remotely activate the cell phone jammers through software, the devices in the system can function normally because there is no jamming signal at that time. However, once a jamming device is turned on and receives the jamming signal, the wireless communication signal will be disrupted. This will prevent the transmission of subsequent control instructions and significantly reduce the transmission distance. As a result, the entire control system for cell phone jammers becomes unstable.
Due to the factors that cause unstable signal transmission, most control systems for cell phone jammers currently rely on wired connections for networking. Although wireless connections are more convenient, the frequencies used in wireless networking are the same frequencies that cell phone jammers need to block or interfere with. Therefore, the use of wireless connections for control systems would lead to unstable functionality. As a result, wired connections remain the preferred method for establishing communication networks for cell phone jammers.
