What factors affect the transmission distance of 433M wireless transceiver module

When we used the 433M wireless transceiver module, we found that the transmission distance of the wireless module was not as far as the manufacturer advertised. What's the matter? In fact, this is a very common phenomenon. After all, the environment should not be the same and interfered. It's not the same, let's take a look at what factors will affect the transmission distance of the wireless transceiver module.

1. Obstacles such as buildings and trees interfere. Buildings are built of reinforced concrete, which can easily shield the signal. Therefore, the transmission distance of the wireless module will be shortened when the building is affected by obstacles such as trees.
2. Electromagnetic interference. The environment tested by the manufacturer is relatively pure, but electromagnetic interference is inevitable in the environment used by the user. Therefore, the wireless module has an electromagnetic interference signal that shortens the transmission distance.
3. Antenna. The height of the antenna has a great influence on the transmission distance. Because users consider setting up a higher antenna, which will increase the cost, they will consider comprehensively. The antenna may not be as high as the manufacturer, so the transmission distance is not that far.

There are many factors that affect the transmission distance of the 433M wireless transceiver module, some are visible to our naked eyes, and some are invisible, so when using the wireless transceiver module, you may wish to consider it comprehensively.
