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.
