6. FAQ
6.1 Communication range is too short
The communication distance will be affected when obstacle exists.
Data lose rate will be affected by temperature, humidity and co-channel interference.
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
Seawater has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
The signal will be affected when the antenna is near metal object or put in a metal case.
Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the
distance).
When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is,
the lower the transmitting power is.
The use of the antenna and the module is poorly matched or the quality of the antenna itself is defective.
6.2 Module is easy to damage
Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will
lead to a permanent damage to the module.
Please check the stability of power supply and ensure the voltage not to fluctuate too much.
Please make sure anti-static measures are taken when installing and using, high frequency devices have
electrostatic susceptibility.
Please ensure the humidity is within limited range for some parts are sensitive to humidity.
Please avoid using modules under too high or too low temperature.
6.3 Bit error rate is too high
When there are co-channel signal interference nearby, be away from interference sources or modify frequency and
channel to avoid interference;
Unfavorable power supply may cause code error. Make sure that the power supply is reliable.
The quality of extension cables and feeders is poor or too long can also cause high bit error rate.
