9 Frequently Asked Questions

9.1 The transmission distance is not ideal

When there is a straight-line communication obstacle, the communication distance will be correspondingly attenuated ;

Temperature, humidity, and co-channel interference will increase the communication packet loss rate ;

The ground absorbs and reflects radio waves, and the test effect close to the ground is poor ;

Seawater has a strong ability to absorb radio waves, so the seaside test effect is 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 speed is set too high (the higher the air speed, the closer the distance) ;

The low voltage of the power supply at room temperature is lower than the recommended value, and the lower the voltage, the

lower the output power ;
The antenna and the module are poorly matched or the quality of the antenna itself is a problem.

9.2

Modules are easily damaged

Please check the power supply to ensure that it is between the recommended supply voltages, if exceeding the maximum value

will cause permanent damage to the module ;
Please check the stability of the power supply, the voltage should not fluctuate greatly and frequently ;

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

devices ;
If there is no special requirement, it is not recommended to use it at too high or too low temperature.


9.3 Bit error rate is too high

There is co-frequency signal interference nearby, stay away from the interference source or modify the frequency and channel to

avoid interference;
If the power supply is not ideal, it may also cause garbled characters. Be sure to ensure the reliability of the power supply;

Poor quality or too long extension cables and feeders can also cause high bit error rates.
