voltage, the smaller the power;
The use of antennas is poorly matched with the module or the quality of the antenna itself is a problem.
11.2 Modules are prone to breakage
Please check the power supply to ensure that between the recommended supply voltages, if the maximum value is
exceeded, the module will be permanently damaged;
Please check the stability of the power supply, the voltage can not fluctuate sharply and frequently;
Please ensure that
the
installation and use process anti-static operation, high-frequency device electrostatic sensitivity;
Please ensure that the humidity during installation and use should not be too high, and some components are
humidity-sensitive devices;
If there is no special need, it is not recommended to use it at too high or too low temperature.
11.3 The bit error rate is too high
There is co-frequency signal interference nearby, stay away from the source of interference or modify the frequency and
channel to avoid interference;
The power supply is not ideal, it may also cause garbled codes, and the reliability of the power supply must be
guaranteed;
Poor quality or long extension cables and feeders will also cause high bit error rates.
