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;

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 2.5V, the lower the voltage, the lower the

transmitting power;
Due to antenna quality or poor matching between antenna and module.
