Problems solved by technology

This solution can realize the physical isolation of the internal and external networks, but the signal transmission of the internal network and the external network can only support one frequency band respectively, and the two need to stagger the frequency bands, otherwise crosstalk problems will easily occur

Abstract

The invention relates to a network signal isolation transmission method, device and system. The method comprises the following steps: receiving network signals sent by different network ends, carrying out signal shunting on the network signals through different power division circuits, and sending the network signals to a signal transceiver through different feeder lines in the same group; wherein different groups of feeder lines correspond to different signal transceivers; and terminal signals sent by the signal transceiver are received through different feeder lines in the same group, and the terminal signals are sent to different corresponding network ends through different power division circuits. According to the scheme provided by the invention, physical isolation of different network signals can be realized more simply, the deployment cost is reduced, and the network security is ensured.

Description

technical field [0001] The present application relates to the technical field of signal transmission, in particular to a network signal isolation transmission method, device and system. Background technique [0002] The application scenarios of wireless networks are becoming more and more extensive. Taking the application in hospital business scenarios as an example, the hospital's intranet (ie local area network) services such as mobile nursing and mobile ward rounds will also use wireless networks. In addition, the hospital's wireless external network (that is, the public network) is generally a simple open network, which is transmitted on the same device as the wireless internal network, and only logically isolated. However, such a deployment method is easy to be accessed by hackers from the external network to attack the internal network, which may leak a large amount of valuable information in the internal network. [0003] In related technologies, the following soluti...
