9Frequently Asked Questions
9.1 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-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 effect is poor;
If there are metal objects 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 poor matching degree of the antenna and the module or the quality of the antenna itself.
9.2 Module is easy to damage
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 cannot 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.
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 lines and feeders will also cause high bit error rates.
