Based on the 5G/4G/3G wireless network provided by major operators, the industrial wireless router uses the IoT card to transmit the data collected from the front end to the back end, realizing the functions of high-speed data transmission and remote management of outdoor equipment. It is a commonly used data transmission equipment in the field of the Internet of things.

However, in practical applications, the transmission distance of industrial wireless routers is often easily affected by obstacles, topography, environment and other factors, resulting in transmission distance affected.

First of all, many people do not have a clear understanding of the concept of the transmission range of industrial wireless routers. Generally, the wireless network signals of industrial wireless routers are marked in the instructions, and the effective transmission distance usually ranges from 100 to 250 meters. Therefore, many people think that as long as this transmission range can receive the signal.

However, this is not the case. The theoretical data are obtained in the ideal test environment, and the specific influencing factors are as follows:

Factor one: the 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 radiation unit at the same point in space under the condition of a certain transmission power to enhance the transmission range.

Factor two: affected by the transmit power of the router itself. This is the decisive factor affecting the transmission range of industrial wireless routers. The greater the power, the wider the transmission range, but according to the relevant national regulations, the maximum transmission power must not exceed 100MW, that is, 20dBm.

Factor three: affected by the weather. The industrial wireless router is different from the ordinary home router. The conditions of most of its applications in the outdoor environment determine that it is greatly affected by the weather. For example, in a thunderstorm, when the humidity of the air increases, the transmission range of the router will become narrower and closer. The harsh outdoor environment also puts forward high requirements for the oxidation resistance and high protection of the router chip.

Factor four: affected by terrain and obstacles. The practical application environment of industrial wireless router is complex and changeable, so it is difficult to show the value of wireless signal range in the test environment, which is mainly affected by the environment and obstacles to interfere with the wireless network. Among them, the barrier walls with glass and metal have the greatest impact on the signal of industrial wireless routers.

To sum up, when users choose an industrial wireless router, according to their own needs, choose the appropriate power and gain antenna products, try to choose to use in the open area, can maximize the transmission range of the router.

Telecom industrial wireless router: www.top-iot.com/ equipment adopts high-performance 32-bit high-speed processor and high-gain antenna, has more sensitive signal search ability and wider coverage orientation, can provide a more stable and wider data transmission environment for industrial field, and provide important security for industrial field, intelligent power distribution, environmental supervision, traffic control and other fields.
