Chapter 6 Frequently asked questions
6.1 Unsatisfactory transmission distance
 When there is a straight-line communication barrier, the communication distance is attenuated accordingly;

Temperature, humidity, and co-channel interference can lead to increased communication packet loss;

The ground absorbs and reflects radio waves and is less effective when tested close to the ground;
 Seawater has a very strong ability to absorb radio waves, so the results of the seaside test are poor;

Signal attenuation can be very severe with metal objects near the antenna, or when placed in a metal case;
 The power register is set incorrectly, the air rate is set too high (the higher the air rate, the closer
the distance);

The low voltage of the power supply at room temperature is lower than recommended, the lower the voltage
the lower the transmit power;

Using an antenna that is poorly matched to the module or the quality of the antenna itself.
6.2 Vulnerability of modules

Please check the power supply to ensure that it is between the recommended supply voltages, exceeding the
maximum value can cause permanent damage to the module;

Please check the stability of the power supply, the voltage should not fluctuate significantly and frequently;
 Please ensure that the installation and use of the process of anti-static operation, high-frequency devices
electrostatic sensitivity;

Please make sure that the humidity during installation and use is not too high, as some of the components
are humidity sensitive;

It is not recommended to use it at too high or too low a temperature if there is no special need.
6.3 BER too high

There is co-channel signal interference in the vicinity, stay away from the interference source or modify
the frequency or channel to avoid the interference;

An unsatisfactory power supply may also cause garbled code, be sure to ensure the reliability of the power
supply;

Poor quality or too long extension cords and feeder cables can also cause high BER.
