8 Frequently Asked Questions
8.1 The communication distance is very close
When there is a straight-line communication obstacle, the communication distance will be correspondingly attenuated.
Temperature, humidity, and co-channel interference will increase the communication packet loss rate.
The ground absorbs and reflects radio waves, and the test effect close to the ground is poor.
Seawater has a strong ability to absorb radio waves, so the seaside test results are poor.
If there is a metal object near the antenna, or is placed in a metal case, the signal attenuation will be very serious.
The power register is set incorrectly, and the air speed is set too high (the higher the air speed, 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 output power.
The antenna and the module are poorly matched or the quality of the antenna itself is a problem.
8.2 Module is easily damaged
Please check the power supply to ensure that it is between the recommended values, as exceeding the maximum value will cause
permanent damage to the module.
Please check the power supply stability, the voltage should not fluctuate greatly and frequently.
Please ensure anti-static operation during installation and use, and high-frequency components are electrostatically sensitive.
Please ensure that the humidity during installation and use should not be too high, and some components are humidity-sensitive
devices.
If there is no special requirement, it is not recommended to use it at too high or too low temperature.
