What factors affect the transmission distance of industrial routers

When purchasing an industrial router, the general user will pay attention to the transmission distance of the industrial router, and mistakenly believe that the transmission distance of the industrial router can receive signals as long as the transmission distance is within the specified range, but this is a big misunderstanding, because industrial routers are different The transmission power and the presence of obstacles between the receiving end will affect the final transmission distance.

The transmission distance given on the industrial router description is the farthest distance under ideal conditions. This condition excludes all kinds of interferences around. However, in actual use, this situation is difficult to achieve. Part of it depends on the transmit power of the router, and the other part depends on the number of obstacles between it and the receiving end. These are the two major factors that affect the final transmission distance of industrial routers.

According to the IEEE802.11 standard, the maximum distance that a general industrial router can cover is usually 100 meters to 300 meters, but the coverage range should mainly depend on whether the environment is open or not; if it is a semi-open space, or an area with isolation , The transmission distance will be reduced accordingly.

Therefore, it needs to be applied according to the needs of users. Therefore, after testing, we found that when there are buildings, objects, and signal interference, the effective distance will be reduced and the network speed will be unstable, and there are many factors such as voltage instability and electromagnetic interference among these reasons. Of course, there are also high-end routers with stable transmission and long distance.

Regarding the transmission distance of industrial routers, everyone should judge according to the actual usage. If there are multiple obstacles in the middle and there are gaps in the transmission of collected data, the transmission distance will be longer than that in a relatively open place. Great attenuation. These issues should be fully considered when placing industrial routers, and the most suitable location should be selected to achieve the longest transmission distance.

 The industrial router supports serial port DTU, wired/wireless dual backup functions, and supports 5G/4G/WIFI/VPN and other networking; it is suitable for multi-channel big data, picture, and video data transmission in industrial field remote monitoring. It has 4 LAN ports, 1 WAN port, 1 RS232 and 1 RS485 (optional); the WAN port can be customized as a LAN port and expanded to 5 LAN ports; the serial port adopts terminal form to meet the requirements of industry for transmission .
