The industrial cellular router adopts high-performance industrial-grade 4G wireless communication module, industrial-grade high-precision and high-stability components, which can adapt to various harsh environments such as high-temperature and cold operation, and providing reliable networking and stable communication for the unattended system. A lot of people are curious about the available transmission range of industrial wireless routers. So, let’s take a look today
Transmission Distance Industrial router
First of all, many people do not have a clear understanding of the transmission distance of industrial routers. Generally, the network signal strength of industrial routers will be marked in the specification, and the effective transmission distance is usually 100~200 meters, so many people think that as long as within this transmission range, they can receive the wireless signals.
However, this is not true. Theoretical data are obtained in an ideal test environment, and the specific influencing factors are mainly as follows:
Factor 1: Affected by the transmitting power.
This is the decisive factor that affects the transmission distance of industrial wireless routers.
The greater the power, the wider the transmission range. However, according to relevant national regulations, the maximum transmission power shall not exceed 100MW, or 20dBm(2.4ghz frequency band). Because of bigger power, can cause bigger radiation, and it is harmful to the human body.
Factor 2: Affected by terrain and obstacles.
The application environment of routers is complicated and changeable, and it is difficult to find the value of the wireless signal range in the real environment. This is mainly because the wireless network is affected by the environment and obstacles, interfering with the wireless network. Among them, glass and metal barriers have the greatest influence on the signals of industrial wireless routers.
Factor 3: High gain antenna can improve the stable receiving distance.
The high gain antenna is to increase the power density ratio of the signals generated by the actual antenna and the ideal radiation unit in the space unit to enhance the transmission range under a certain condition.
Factor 4: Affected by the weather.
Different from domestic routers, industrial routers are mostly used in outdoor environments, which determines that they are greatly affected by the weather. For example, in a thunderstorm, when the air humidity increases, the transmission range of routers will become narrower and closer. Harsh outdoor environment also have high requirements for the anti-oxidation
In short, when choosing industrial routers, users should choose products with appropriate power and gain antennas according to the needs and try to use them in open areas to maximize the transmission range of routers.
