6. FAQ

6.1 Communication range is too short

l The communication distance will be affected when obstacle exists.
l Data lose rate will be affected by temperature, humidity and co-channel interference.
l The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
l
Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
l The signal will be affected when the antenna is near metal object or put in a metal case.
l Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the distance).
l 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.
l Due to antenna quality or poor matching between antenna and module.
