With the development of industrial internet, 4G industrial routers have been increasingly widely used. However, how to choose the appropriate 4G industrial router based on actual needs is a concern for many users. Therefore, this article will deeply analyze the working principles, important parameters, and selection points of 4G industrial routers, and recommend high-quality brands and products to provide selection references.

4G Industrial Routers

Working Principles of 4G Industrial Routers

4G industrial routers achieve wireless data transmission of industrial site data through built-in 4G communication modules. Their working principles mainly include:

1. Data Collection: Collect data from on-site devices through interfaces such as serial ports and Ethernet.
2. Data Processing: Perform data caching, security verification, and other processing.
3. 4G Wireless Transmission: Send data wirelessly to remote platforms via the built-in 4G module.
4. Parameter Configuration: Allow remote configuration of router parameters, such as APN and heartbeat packets.
5. Status Monitoring: Monitor signal strength, data traffic, and other statuses to ensure transmission quality.

Key Parameters of 4G Industrial Routers

When selecting 4G industrial routers, consider the following key parameters:

1. 4G Module Model: Different modules have varying transmission rates and stability.
2. Interface Types: Choose interface types such as serial ports and Ethernet based on needs.
3. Operating Temperature Range: Some models can operate in -40°C low-temperature environments.
4. Protection Level: For outdoor use, choose products with IP66 protection level.
5. Power Consumption Optimization: Optimize router sleep-wake mechanisms to extend backup power time.
6. Intelligent Scheduling: Schedule data transmission on demand to optimize traffic usage.
7. Remote Management: Flexibly complete remote configuration, debugging, and diagnostics.

Typical 4G Industrial Router Brands

Yeaplink: Products offer high cost-effectiveness, strong technical capabilities, and good user reputation. Comprehensive considerations suggest that brands with balanced technical strength and product quality are more recommended, such as Starcrea and Tektronix. Users can choose suitable 4G industrial router brands and product models based on their own needs.
