Factors affecting the wireless transmission distance of 4g modem

An industrial 4g modem router is a wireless communication device for the Internet of Things. It can ensure the stable connection of the wireless network, use the operator's network to provide users with long-distance wireless data transmission functions, and realize the high-speed and stable network deployment of industrial equipment outdoors.

Many people want to know how the transmission distance of industrial routers is affected, and I will talk to you this time!

1. Affected by the transmit power of the router itself.

Transmitting power is a fundamental element that affects the reasonable transmission distance of 4 industrial routers. The greater the output power, the wider the transmission range, but according to the relevant national requirements, the larger transmission power cannot exceed 100MW, that is, 20dBm (2.3GHz frequency band).

2. Affected by landforms and obstacles:

The specific application scenarios of wireless routers are numerous and complicated, and there is no way to show the standard value of the network signal category under the interface test. The key is that the natural environment and obstacles affect the wireless network. Among them, barrier walls with laminated glass and metal materials have a greater impact on the data signal of industrially produced wireless routers.

3. The high-gain antenna can improve the stable receiving distance:

The gain value is to increase the power ratio of the data signal caused by the specific wireless router antenna and the idealized radiation source module at the same point in the indoor space under the condition of the transmission power, and improve the transmission range of the industrial router.
