At present, there are many manufacturers of 5G industrial CPE/5G industrial gateways in the world, but the quality and price are uneven. Many companies do not fully consider the environment of the project application site when purchasing, resulting in various unstable phenomena during use, increasing unnecessary maintenance costs.

Here are a few common mistakes that can be made in the purchasing process:
1. Equipment does not work properly in extreme outdoor environments
In some areas, the lowest temperature in winter is tens of degrees below zero, while in some areas the outdoor temperature is very high in summer. In these cases, it will be found that the commercial gateways purchased online often have problems during use, and the service life will be greatly reduced due to salt-alkali, temperature, static electricity and other reasons. The industrial-grade gateway can operate stably in harsh field environments, and the industrial-grade design ensures that its internal devices will not be affected by the environment and rapidly age.

2. The power supply is not guaranteed, the voltage fluctuates greatly, and the equipment is often shut down or damaged
Although household electricity voltage is very stable, in many industrial sites, because the power supply voltage cannot be fully guaranteed, the voltage fluctuates greatly. For example, 220V AC directly drops to 100V, and 24V DC fluctuates between 12 and 48V. In this case the equipment is prone to downtime or damage. Therefore, it is necessary to choose gateway products with wide voltage input. After all, in industrial sites, even one minute of downtime will cause great economic losses.

3. The virtual serial port function has high end-to-end data transmission delay, resulting in untimely data collection
Many companies have purchased equipment from non-professional manufacturers. After configuration and installation, they found that when the virtual serial port function is used, the data collected from the serial port to Ethernet is often not collected in time, or even data is lost, causing impact and loss on field applications. This problem occurs because the data stays in the Ethernet protocol stack for too long and cannot achieve low-latency end-to-end transmission. In the final analysis, the serial server manufacturers have insufficient technical accumulation in product software. These problems are very fatal in some factory automation applications.
