Effective coverage of industrial-grade wireless routers

Industrial-grade 4G routers use high-performance industrial-grade 4G wireless modules, industrial-grade high-stability and high-precision components, and various complex environments that should work in high temperature and severe cold, providing reliable networking and stable communication for unattended systems. Therefore, many people are curious about the effective coverage of industrial-grade wireless routers. Let's take a look today.

First of all, many people do not have a clear understanding of the concept of the transmission range of industrial-grade wireless routers. Generally, the wireless network signals of industrial wireless routers are marked in the manual. Usually, the effective transmission distance ranges from 100-250 meters, so many people think that As long as it is within this transmission range, the signal can be received.

But this is not the case. The theoretical data is obtained in an ideal test environment. The specific factors affecting the effective range of industrial-grade wireless routers mainly include the following four points:

Factor 1: It is affected by the transmit power of the router itself. This is the decisive factor affecting the transmission range of industrial-grade wireless routers. The greater the power, the wider the transmission range, but according to relevant national regulations, the maximum transmit power shall not exceed 100MW, which is 20dBm (2.4GHz frequency band). Because the greater the power, the greater the radiation, which is harmful to the human body.

Factor 2: Affected by the weather. Industrial-grade wireless routers are different from ordinary household routers. Most of them are used in outdoor conditions, which determine that they are greatly affected by the weather. For example, in thunderstorms, the humidity of the air increases, and the transmission range of the router will be narrowed. close. The harsh outdoor environment also places high requirements on the oxidation resistance and high protection of the router's chips.

Factor 3: A high-gain antenna can improve the stable receiving distance. The gain is to increase the power density ratio of the signal generated by the actual antenna and the ideal radiating element at the same point in space under the condition of a certain transmit power, so as to enhance the transmission range.

Factor 4: Affected by terrain and obstacles. The actual application environment of the router is complex and changeable, and it is difficult to show the wireless signal range value in the test environment, which is mainly affected by the environment and obstacles, which interfere with the wireless network. Among them, the obstacle wall with glass and metal has the greatest influence on the signal of the industrial wireless router.

In short, when users choose industrial wireless routers, they should choose products with appropriate power and gain antennas according to their own needs, and try to use them in open areas, which can maximize the transmission range of the router.
