How far is Wi-Fi transmission distance of 4g industrial router? Theoretical distance is about 100-300 meters as transmission distance depends on whether there is interference around it, if there is no obstacle or interference within the range of 100-300 meters from the router, the maximum transmission distance can be achieved. However, it is impossible to occur in the environment where 4g industrial router used, but what specific factors will impact the effective distance of transmission, please check below for reference.
1.The transmit power of the router itself
Transmit power is a fundamental factor affecting 4g industrial router and the reasonable transmission distance of wireless router. The greater the output power, the wider the transmission range, but the maximum transmission power cannot exceed 100MW which is 20dBm (2.3GHz frequency band) according to relevant requirements, as the greater output power make greater radiation source, which is harmful to human body.
2.High-gain antenna improve smooth reception distance
Wi-Fi transmission distance of 4g industrial router is about 35-50 meters under normal circumstances, which not use external antenna or other gain device. If you have requirements for transmission distance, you can add auxiliary equipment yourself.
3.Landforms and obstacles
The actual application scenarios of 4g industrial router are complicated, if network signal range indicator not show under interface test, this is mainly due to the influence of environment and obstacle which affect the wireless network. Among them, barrier walls with glass and metal have greater impact on the signal.
