Chapter XII FAQ

12.1 The transmission distance is not ideal

When linear communication obstacles, communication distance will be the corresponding attenuation;

Temperature, humidity, same frequency interference, can lead to communication packet loss rate increase;

The ground absorption and reflection the radio waves, near ground test effect is poorer;

Seawater has a strong ability to absorb the radio waves, so the test effect is poor;

Near the antenna with metal objects, or placed in a metal casing, the signal attenuation is very severe;

Power register setting error, air rate set too high, the higher the air velocity, the closer distance);

Power low voltage is lower than the recommended value at room temperature, the lower the voltage to send power

is smaller;
The matching degree between antenna and module is poor or the quality of antenna itself is wrong.


12.2 Module damage

Please check the power supply, ensure the recommended between the power supply voltage, such as more than

the maximum value will cause the module permanent damage.
Please check the power supply stability and voltage cannot significantly fluctuate frequently;

Please ensure installation using anti-static operation, high frequency devices electrostatic sensitivity,

Humidity shoulds not be too high, please ensure that the installation process of components for humidity sensitive

device;
It is not recommended to use at high or low temperature if there is no special requirement.


12.3 The bit error rate is too high

Near the same frequency interference, away from the interference sources or change frequency, channels to avoid

interference;
Power not ideal also may cause garbled, be sure to guarantee the reliability of the power supply;

Extension wire, feeder quality is poor or too long, will also cause high bit error rate.
