Chapter Seven Frequently Asked Questions

7.1 The transmission distance is not ideal

When there is a straight-line communication obstacle, the communication distance will be attenuated accordingly;

Temperature, humidity, and co-channel interference will increase the communication packet loss rate;

he ground absorbs and reflects radio waves, and the test effect is poor when it is close to the ground;

Seawater has a strong ability to absorb radio waves, so the seaside test effect is poor;

There are metal objects near the antenna, or placed in a metal case, 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 matching degree between the antenna and the module is poor or the quality of the antenna itself is problematic.


7.2 The module is easily damaged

Please check the power supply to ensure that it is within 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, the voltage cannot fluctuate greatly and frequently;

Please ensure anti-static operation during installation and use, and high-frequency devices are electrostatically sensitive;

Please ensure that the humidity during installation and use should not be too high, 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.


7.3 The bit error rate is too high

There is co-channel signal interference nearby, stay away from the source of interference or modify the frequency and channel to

avoid interference;
Unsatisfactory power supply may also cause garbled characters, so ensure the reliability of the power supply;
