In the vast world of Industrial Internet of Things (IIoT), wireless communication technology plays a crucial role. Among them, industrial wireless bridges, as key devices for achieving long-distance and high reliability wireless connections, are widely used in fields such as industrial automation, intelligent monitoring, and remote data acquisition. For traditional industries, mastering the pairing method of industrial wireless bridges is the foundation for building efficient and stable wireless networks. This article will delve into the pairing method of industrial wireless bridges, in order to provide valuable references for the digital transformation of traditional industries.

1、 Traditional configuration method: Fine operation to ensure stability

1. Basic settings and IP planning
   Firstly, it is necessary to clarify the IP address planning of the primary and secondary wireless bridges, ensuring that they are in different network segments to avoid conflicts. For example, the main network bridge can be set to 192.168.1.1, while the secondary network bridge can be set to 192.168.2.1. This step is the foundation for subsequent configuration and the key to ensuring network stability.

2. Separate connection and configuration
   Main bridge configuration: Connect the main bridge separately to the computer and access its management interface through a browser, usually with an IP address and port number. In the configuration interface, set the default "3G/4G dial-up" if supported or wired network access method, and insert the SIM card for automatic dial-up connection to the network if applicable.
   Secondary bridge configuration: Similarly, connect the secondary bridge separately to the computer and change its IP address to a different network segment from the primary bridge. In the configuration interface, change the default internet connection method of the secondary bridge to "dynamically obtain address" and uncheck the "change WAN port to LAN port" option to obtain the network from the primary bridge.

3. Connection and testing
   After completing the above configuration, connect the LAN port of the main bridge to the WAN port of the secondary bridge. At this point, the secondary bridge will automatically obtain the IP address of the same network segment from the primary bridge through DHCP allocation. Subsequently, you can use a mobile phone or other terminal to connect the WiFi signals of the primary and secondary bridges separately for internet testing to verify whether the configuration is successful.

2、 Advanced configuration method: flexible response to complex scenarios

1. WPS one click pairing
   For industrial wireless bridges that support the WPS Wi-Fi Protected Setup function, quick pairing can be achieved through the WPS button. The specific steps include:

Switch the two bridges to AP access point and client client mode respectively.
Short press the WPS button on one of the bridges, and then short press the WPS button on the other bridge within 15 minutes.
Observe the signal indicator lights of the bridge. When the signal indicator lights of both bridges are constantly on, it indicates successful pairing.
This method simplifies the configuration process and improves the convenience of on-site installation, especially suitable for scenarios that require rapid deployment.

1. Custom configuration and mode selection
   For scenarios that require higher flexibility and customization, custom settings can be made by entering the configuration interface of the bridge. For example, in AP mode, configure the wireless parameters of the transmitting end such as SSID, channel, encryption method, etc., and in Client mode, configure the connection parameters of the receiving end such as scanning and connecting to the specified SSID, setting the same channel and encryption information, etc.

In addition, other advanced features such as VLAN partitioning, QoS settings, link aggregation, etc. can be selected according to actual needs to further optimize network performance and security.

There are various pairing methods for industrial wireless bridges, including traditional fine operation methods and modern one click pairing technology. Traditional industries should flexibly choose matching methods based on actual scenarios and needs. Meanwhile, with the continuous advancement of technology and the expansion of application scenarios, the functionality and performance of industrial wireless bridges will also continue to improve, providing stronger support for the digital transformation of traditional industries.
