Note:
1. The module transmission data rate will affect Transmission distance ,the higher the data rate , the closer the
distance, and the lower the receiving sensitivity.
2. The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the
voltage, the lower the TX power.
3. The module central frequency will change as the operating temperature change, use it under suggest temperature,
the module can work well.
4. The antenna will strongly affect the communication distance, please select matched antenna and connect it
correctly.
5. The module mount will affect the communication distance.
