4. Common problem
4.1 Unsatisfactory transmission distance

When there is a straight line communication obstacle, the communication distance will be attenuated
accordingly;

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 when it is close to the ground;

Sea water 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 power output;

The matching degree of the antenna and the module is poor or the quality of the antenna itself is problematic.
4.2 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, and the voltage should not fluctuate significantly and frequently;

Please ensure that the installation and use process is anti-static, and high-frequency components are
electrostatically sensitive;

Please ensure that the humidity should not be too high during installation and use, and some components are
humidity sensitive devices;

If there is no special requirement, it is not recommended to use at too high or too low temperature
4.3 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;

Unsatisfactory power supply may also cause garbled codes. Be sure to ensure the reliability of the power supply;

Poor or too long extension cables and feeders can also cause high bit error rates.
