Reasons and solutions that affect the coverage of wireless routers

Although 5G routers have come out, many people still use 4g wireless routers, so do you know how to expand the coverage of 4g industrial routers? What are the factors that affect the coverage of industrial routers?

The current 5g industrial routers can realize on-site standardized access of complex models in industrial scenarios, not only for data center computing and storage, but also for remote control, remote maintenance, and remote publishing. In the remote maintenance of equipment, the computer technology wireless industrial gateway can realize remote maintenance and management of construction machinery and process systems, remote maintenance and management of water treatment equipment, and solve rare remote processing problems.

The coverage in the wireless router refers to the effective working distance of the router! According to the IEEE802.11 standard, the maximum distance that a general wireless router can cover is usually 300 meters.

Factors affecting the coverage of industrial-grade 4g wireless routers:

1. The stronger the antenna, the wider the signal, or the number of antennas is also an important factor affecting the coverage of WIFI signals. Otherwise, you will not see 4g routers with 3 or 5 antennas on the market. At the same time, the antenna quality of industrial-grade 4g routers is also critical. A good quality antenna can achieve high gain signals, and the wifi distance can reach more than 100 meters.

2. Environment In an open environment, the signal coverage of 4g wireless routers is wider. If there are water signal interference sources, metal objects or wall interference in the transmission environment, it will inevitably affect the signal of the 4g router. The result of the influence is based on the degree of influence of the interfering substance on the signal. For example, the thickness of the wall in the transmission medium or wall material has different effects on signal coverage.

3. The coverage of the wireless router is related to the openness of the environment. In the case of the device without an external antenna, the field of view is about 300 meters; if it is a semi-open space or an area with partitions, the transmission is about About 35~50 meters. If you rely on an external antenna (to do a link), the transmission distance can reach 30-50 kilometers or more, depending on the gain of the antenna itself.

Industrial-grade 4g wireless router coverage adjustment method:

1. Adjust the antenna: Because the antenna affects one of the coverage factors of the 4g wireless router, choose a whip antenna or a full-frequency suction cup antenna, choose a small business antenna or a 5GBi antenna, and the number of antennas are all used Coverage of 4g router. Can be expanded and adjusted to varying degrees.

2. Networking mode: If the Wi-Fi signal coverage is not good, there will often be signal blind spots. The usual measure is to use a high-power wireless router or Wi-Fi relay, that is, networking mode to achieve coverage adjustment.
