outside of the enclosure.
The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly weakened.
11 Common Questions
11.1 Unsatisfactory transmission distance
When there are linear communication barriers, the communication distance is attenuated accordingly.
Temperature, humidity, co-channel interference, which can lead to increased communication packet loss.
The ground absorbs and reflects radio waves and is less effective for testing close to the ground.
Seawater has a very strong ability to absorb radio waves, so the seaside test is poor.
metal objects near the antenna, or placed in a metal case, signal attenuation will be very serious.
Wrong setting of the power register, too high setting of the 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, and the lower the voltage the
less power is generated.
Use antenna and module match poorly or antenna itself quality problems.
11.2 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 of the process of 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.
It is not recommended to use at too high or too low temperature if there is no special need.
11.3 BER is too high
If there is interference from the same frequency signal nearby, stay away from the interference source or modify the frequency or
channel to avoid the interference.
Poor power supply may also cause garbled code, be sure to ensure the reliability of the power supply.
Poor quality or too long extension cords and feeders can also cause high BER.
