8 Frequently Asked Questions

8.1 The communication distance is very close

When there are straight-line communication obstacles, the communication distance will be correspondingly

attenuated.
Temperature, humidity, and co-channel interference will cause the communication packet loss rate to increase.

The ground absorbs and reflects radio waves, and the test effect is poor when close to the ground.

Seawater has a strong ability to absorb radio waves, so the test results at the seaside are poor.

If there are metal objects near the antenna, or if it is placed in a metal case, the signal attenuation will be very

serious.
The power register setting is wrong and the air rate is set too high (the higher the air rate, the closer the distance).

The low voltage of the power supply at room temperature is lower than the recommended value. The lower the

voltage, the smaller the power generated.
There is a poor match between the antenna and the module or there is a problem with the quality of the antenna

itself.

8.2 Modules are easily damaged

Please check the power supply to ensure that it is within the recommended value. If it exceeds the maximum value,

it will cause permanent damage to the module.
Please check the stability of the power supply. The voltage cannot fluctuate greatly and frequently.

Please ensure anti-static operation during installation and use, as high-frequency devices are sensitive to static

electricity.
Please ensure that the humidity during installation and use should not be too high, as some components are

humidity sensitive.
If there are no special needs, it is not recommended to use it at too high or too low temperature.
