In the IIoT environment, the choice of network devices directly affects the stability and security of the entire system. As the core device of industrial networks, industrial routers not only undertake the task of data transmission, but also need to ensure the security and integrity of data during transmission. Therefore, when purchasing an industrial router, you need to consider it from multiple perspectives to ensure that the selected device can meet your networking application needs.

1. Clarify application requirements

Different application scenarios have different requirements for routers. Before purchasing, it is necessary to understand the specific requirements of the application in detail, such as bandwidth, latency, connection stability, and so on. For example, video surveillance requires high-bandwidth, low-latency routers to ensure real-time data transmission; However, big data transmission focuses more on throughput and stability. Therefore, clarifying the application requirements is the first step in selecting an industrial router.

2. Evaluate hardware performance

Hardware performance is the core of industrial routers, directly affecting their transmission speed, stability, and reliability. The following are several key hardware performance parameters that require attention:Processor performance: The stronger the processor performance, the better the processing capability of the router, which can support more device connections and higher data transmission rates.
Number of network interfaces: Ensure that the router can meet the needs of existing devices and future expansion. The multi-WAN port design can enhance the flexibility and reliability of network connections.
Dustproof and waterproof rating and temperature adaptability range: The industrial environment is complex and changeable, and factors such as dust, moisture, oil mist, and temperature fluctuations can affect routers. Therefore, when purchasing, it is necessary to focus on the dustproof and waterproof rating and temperature adaptability range of the router. A high level of protection can effectively ensure the stable operation of the device in harsh environments.

3. Pay attention to stability

The stability of industrial routers is an indispensable feature. Due to the harsh industrial environment, such as high temperature, high humidity, vibration, etc., routers are required to have high stability and reliability. The following factors can help improve the stability of the router:Protection level: The higher the protection level, the stronger the router's adaptability to harsh environments.
Heat dissipation performance: Good heat dissipation performance can ensure the router to operate stably for a long time under high temperature conditions.
Redundant design: For example, the dual SIM card redundant backup function can automatically switch to another SIM card when one SIM card fails, ensuring that the network is never disconnected.

4. attach importance to safety

In industrial networks, data security and privacy are of utmost importance. When shopping, it is necessary to choose a router with strong security features, such as support for advanced encryption standards, built-in firewalls, and VPN functionality. These functions can effectively protect the network from attacks and illegal access, ensuring the secure transmission and storage of data.

Data encryption: The router should support the Advanced Encryption Standard to ensure security during data transmission.

Firewall and VPN: The built-in firewall can effectively prevent external malicious attacks, while the VPN function can achieve remote secure access and protect the security boundary during data transmission.
Access control and authentication: Support multiple authentication methods and fine-grained access control policies to ensure that only authorized users and devices can access the network.

5. Consider scalability and management maintenance

With the development of industrial automation and intelligence, more devices may need to be connected to the network in the future. Therefore, it is necessary to choose a router with good scalability so that new devices and functions can be easily added in the future. At the same time, the management and maintenance of the router is also an important factor to consider when purchasing.Interface type: Ensure that the router supports commonly used protocols in industrial communication and has a rich variety of interface types to facilitate the connection of various industrial devices and sensors.
Remote management: The router should have remote management capabilities, such as configuration, monitoring, and troubleshooting through a Web interface, to reduce on-site maintenance costs.
Software upgrade and maintenance: consider whether the router supports firmware online upgrade and whether the manufacturer provides long-term technical support and software update services.

6. Brand and Reputation

Brand and reputation are also factors that cannot be ignored when shopping. Choosing well-known brands and understanding user reviews and feedback on products can help you purchase industrial routers with stable performance and excellent service. At the same time, the technical support of the manufacturer is also very important. A company that can provide timely technical support, respond quickly to customers, and solve problems is more reliable.

7. Price Factor

When shopping, you also need to choose the right equipment according to your actual needs and budget. Don't just pursue low prices and ignore the quality and performance of the equipment, otherwise it may bring greater risks and losses.

The purchase of industrial routers needs to be considered from multiple aspects such as application requirements, hardware performance, stability, security, scalability, management and maintenance, and price. By selecting the appropriate industrial router and taking corresponding security measures, network security can be strengthened and the stable operation of the industrial network can be ensured.
