7 FAQ
7.1 Communication range is too short
The communication distance will be affected when obstacle exists.
Temperature, humidity, and co-frequency interference will increase the communication packet loss rate.
The ground absorbs and reflects radio waves, and the test effect is poor near the ground.
Sea water has a strong ability to absorb radio waves, so the seaside test results are poor.
If there is a metal object near the antenna or placed in a metal shell, the signal attenuation will be very serious.
The power register is set incorrectly, 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 lower the power output.
The matching degree of the antenna and the module is poor or the quality of the antenna itself is problematic.
7.2 Module is easy to damage
Please check the power supply to ensure that it is between the recommended power supply voltage. If it exceeds the
maximum value, it will cause permanent damage to the module.
Please check the stability of the power supply.
Please ensure anti-static operation during installation and use, and high-frequency components are electrostatically
sensitive.
Please ensure that the humidity during installation and use should not be too high, and some components are
humidity sensitive.
If there is no special requirement, it is not recommended to use it at too high or too low temperature.
7.3 Bit error rate is too high
There is co-channel signal interference nearby, stay away from the interference source or modify the frequency and
channel to avoid interference.
Unsatisfactory power supply may also cause garbled codes. Ensure the reliability of the power supply.
Poor or too long extension cables and feeders can also cause high bit error rates.
