Note Note Note 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.
