In the vast world of Industrial Internet of Things (IIoT), the stability and coverage of wireless networks are crucial for ensuring communication between devices. When the coverage of a single wireless router cannot meet the demand, the bridging technology of multiple Industrial Lte Router becomes particularly important. This article aims to explain the advanced techniques and precautions of wireless router bridging to engineers and technicians in traditional industries, helping them better apply this technology in IIoT projects.
Wireless router bridging, also known as Wireless Distribution System (WDS) bridging, refers to connecting two or more Industrial Lte Router together through wireless signals, forming a logical single network. In bridging mode, Industrial Lte Router will forward the received wireless signals to other devices, thus extending the coverage of the wireless network. This technology can effectively solve the problem of limited coverage of a single wireless router, especially in large factories, warehouses, or outdoor venues that require extensive coverage.
1. Select Routers with WDS Functionality: Ensure that the purchased Industrial Lte Router support the WDS function, which is the foundation for bridging.
2. Configure the Main Router: First, configure the wireless parameters of the main router, including SSID (network name), encryption method, and password. Ensure that the DHCP service of the main router is turned on to distribute IP addresses to connected devices.
3. Configure the Secondary Router: Enter the management interface of the secondary router, enable WDS function, and set the same wireless parameters as the main router. In the list of scanned wireless signals, select the SSID of the main router and enter the password to connect.
4. Adjust IP Addresses: Modify the IP address of the secondary router to a different address in the same subnet as the main router to avoid IP address conflicts. Meanwhile, turn off the DHCP service of the secondary router to ensure that connected devices obtain IP addresses from the main router.
5. Test the Connection: After completing the configuration, use a mobile device or computer to connect to the wireless network and test whether it can successfully access network resources.
1. Signal Quality: Ensure good signal quality between the main router and the secondary router to avoid unstable connections or decreased data transmission rates due to signal attenuation. If the distance is far or there are obstacles blocking the signal, consider using higher-gain antennas or repeaters to enhance the signal.
2. Security: When configuring Industrial Lte Router, always set strong passwords and adopt secure encryption methods such as WPA2 to protect the wireless network from unauthorized access and attacks. Additionally, regularly update the router's firmware and software patches to ensure its security and stability.
3. Compatibility: Although most Industrial Lte Router support the WDS function, there may be differences in configuration and compatibility among different brands and models. Therefore, when selecting routers, it is recommended to prioritize the same brand or models that have been tested and verified to ensure the stability and reliability of bridging.
4. Topology Structure: When designing the wireless network topology, it is necessary to plan reasonably based on actual needs and site environments. For example, in large factories or warehouses, a star topology can be adopted to bridge multiple secondary routers to the main router. In rectangular coverage areas, a linear topology can be used for expansion. At the same time, avoid excessive WDS bridging levels to ensure network stability and wireless speed.
5. Redundancy Backup and Load Balancing: In critical business scenarios, it is recommended to adopt redundancy backup and load balancing technologies to improve network reliability and stability. By configuring multiple Industrial Lte Router as backup nodes or load balancing nodes, automatic switching to backup nodes or balanced load distribution can be achieved when the main node fails or the load is too high.
The bridging technology of Industrial Lte Router is an effective means to achieve extensive coverage of wireless networks in IIoT. Through reasonable configuration and adherence to precautions, the stability and reliability of bridging can be ensured, providing strong support for the development of IIoT. As engineers and technicians in traditional industries, we should continuously learn and master new technologies to adapt to the rapid development and changes in IIoT.
