Ⅳ Frequently Asked Questions

4.1 Unsatisfactory transmission distance

A corresponding attenuation of communication distance when linear communication barriers exist.

Temperature, humidity, and co-channel interference, which can lead to higher communication packet loss rates.

The ground absorbs and reflects radio waves, and the test effect is poor near the ground.

seawater has a very strong ability to absorb radio waves, so the seaside test effect is poor.

metal objects near the antenna, or placed in a metal shell, signal attenuation will be very serious.

Wrong setting of power register, too high setting of air rate (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 less power is generated
The use of antenna and module match the degree of poor or antenna itself quality problems.


4.2 Module is vulnerable to damage

Please check the power supply to ensure that it is between the recommended supply voltages, as exceeding the

maximum will cause permanent damage to the module.
Please check the stability of the power supply, the voltage should not fluctuate significantly and frequently.

Please ensure that the installation and use process anti-static operation, high-frequency devices electrostatic

sensitivity.
Please ensure that the installation and use process humidity should not be too high, some components are

humidity-sensitive devices.
If there is no special demand is not recommended to use at too high or too low temperature.


4.3 BER is too high

Nearby interference with the same frequency signal, away from the source of interference or modify the frequency,

channel to avoid interference.
unsatisfactory power supply may also cause garbled codes, be sure to ensure the reliability of the power supply.

Poor quality or too long extension cable or feeder line may also cause high BER.
