The network version of the cell phone jammer system, the signal shielding terminal, that is, the network version of the mobile phone signal shielding device, and the network cable connection between the control computer, it is best not to exceed 100 meters.
Friends who are familiar with the network know that the twisted pair has an insurmountable transmission distance of 100 meters, whether it is a three-type twisted pair with a 10M transmission rate, a five-type twisted pair with a 100M transmission rate, or even a 1000M transmission rate. Category 6 twisted pair, the farthest effective transmission distance is less than 100 meters. In the integrated wiring specification, it is also clearly required that the level should not exceed 90 meters, and the total length of the link should not exceed 100 meters. That said, 100 meters is a limit for wired Ethernet, which is the length of the link from the network card to the hub device.
Of course, the online version of the mobile phone signal shielding system cannot escape this rule. The network cable transmission should not exceed 100 meters. If it exceeds 100 meters, it will affect the transmission rate and also affect the transmission efficiency, resulting in the instability of the signal transmission of the mobile phone signal shielding system. What if the length of the network cable used by the on-site server and the terminal of the mobile phone signal shielding system exceeds 100 meters?
There are two ways to solve this problem. First, you can connect a switch in the middle to solve the problem of transmission delay or instability caused by the use of a long network cable. Second, you can directly use optical fiber to access. In this way, even if the distance between the control host and the terminal of the mobile phone signal shielding system exceeds 100 meters, there is no need to worry about the signal transmission problem.
