FAQ5.1 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. Sea water 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 d istance). 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. Due to antenna quality or poor matching between antenna and module.
