Chapter 4 Frequently Asked Questions
4.1 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 ;

The 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 results are 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 power output;

The matching degree between the antenna and the module is poor or the quality of the antenna itself is problematic.
4.2 The module is easily damaged

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, 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.
4.3 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 be sure to ensure the reliability of the power supply;

Poor quality or too long extension lines and feeders will also cause high bit error rates.
