7. FAQ
7.1 Poor transmission range
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 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, 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.
7.2 Module is easy to damage
Check the power supply to ensure that permanent damage to the module occurs between recommended supply
voltages, if exceeded;
Please check the stability of the power supply. The voltage cannot fluctuate significantly and frequently.
Please ensure anti-static operation during installation and high frequency device electrostatic sensitivity;
Please ensure that the installation process is not too humid. Some components are humidity sensitive.
If there is no special requirement, it is not recommended to use it at too high and too low temperatures.
7.3 The 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.
