What are the precautions for choosing a wireless industrial router?

1. The stability of industrial-grade 4G routers. Because it is used unattended, the stability of the device is very important, which is related to the stability of the entire network data and the realization of functions. The device needs to support software restart and hardware watchdog to ensure long-term operation without problems.

2. The scalability of industrial-grade 4G routers. Some 4G industrial routers have only 2 network ports, and some do not support serial ports, so when purchasing, consider the compatibility of subsequent projects. For example, for PLC remote monitoring, in addition to the PLC's own interface, touch screens and video surveillance may also be used. Therefore, it is best to choose an industrial-grade 4G router with multiple network ports and serial ports.

3. The price of industrial-grade 4G routers. Due to cost considerations, price is an important factor considered by many users. The price is too high, beyond the cost budget, and users cannot accept it. Is the price as low as possible? In fact, not all. The unusually low price means that the product may not use industrial-grade modules, which may affect the stability. It cannot be because the initial purchase cost is low, and the later maintenance cost is high, and the gain is not worth the loss. Therefore, a reasonably priced industrial-grade 4G router is very important.

4. Technical support. 4G industrial routers are not like ordinary routers. Many projects will use VPN functions, port mapping and other network technologies. If you are not very familiar with the network, you may encounter problems like this during use, so it can be timely Companies that provide technical support and respond quickly to customers are important.

5. Industrial-grade 4G router chip. Industrial-grade 4G routers support the use environment of -20° to 75°, so the project implementation environment needs to be considered.

6. 4G frequency band. The 4G full Netcom industrial router supports 4G signals, eliminating the trouble of changing cards.
