Chapter 6 FAQ

6.1 Transmission distance

When there is a linear communication barrier, the communication distance will decay accordingly;

Temperature, humidity and the same frequency interference will lead to the increase of communication packet loss

rate;
The ground absorbs and reflects radio waves, and the test results are poor near the ground;

Sea water has a strong ability to absorb radio waves, so the seaside test results are poor;

If there are metal objects near the antenna or placed in a metal shell, the signal attenuation will be very serious;

Power register set wrong, air speed set too high (the higher the air speed, the closer the distance);

At indoor temperature, the power supply low voltage is lower than the recommended value, the lower the voltage,

the smaller the power;
The use of antenna and module matching degree is poor or the quality of the antenna itself.
