7.1 Communication distance 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
distance);
 The power supply low voltage under room temperature is lower than recommended value, the lower the
voltage, the lower the transmitting power；
 Due to antenna quality or poor matching between antenna and module.
7.2 Module is easy to damage
 Please check the power supply source, ensure it is between the recommended supply voltage, voltage
higher than the maximum will damage the module.
 Please check the stability of power source, the voltage cannot fluctuate too much;
 Please make sure antistatic measure are taken when installing and using, high frequency devices have
electrostatic susceptibility;
 Please ensure the humidity is within limited range, some parts are sensitive to humidity;
 Please avoid using modules under too high or too low temperature.
