8. FAQ
8.1 Communication distance is very short
When there is a straight-line communication barrier, the communication distance decays accordingly
。
Temperature, humidity, and concourse interference can lead to increased packet loss rates
。
The ground absorbs and reflects radio waves, and the test effect near the ground is poor
。
Sea water has a strong ability to absorb radio waves, so the seashore test results are poor
。
There are metal objects near the antenna, or the signal decay can be very severe if placed in a metal shell
。
Power register setting is wrong, air rate setting is too high (higher air rate, closer distance)
。
The lower the power supply voltage at room temperature is lower than the recommended value, the lower the voltage,
the lower the power
。
The use of antennas to match modules is poor or the antenna itself is of poor quality
。
8.2 Module is easy to be damaged
Check the power supply to ensure that the module is permanently damaged between recommended values if the
maximum value is exceeded
。
Check the stability of the power supply and the voltage does not fluctuate significantly or frequently
。
Make sure that the installation is using process anti-static operation and that the high-frequency device is static
sensitive
。
Make sure that the process humidity should not be too high for installation and that some components are humidity
sensitive devices
。
Use at too high or too low a temperature is not recommended if there are no special needs
