Note:
1
．
Noted that higher radio data rate causes of shorter communication disdance.
2
．
Noted that higher radio data rate causes of lower sensitivity.
3
．
Noted that lower input voltage causes of lower output power.
4
．
Noted that the operate temperature out of range -40℃
～
85℃ will influence the center frequency.
5
．
Be sure to use a match antenna and mount it in the right way.
6
．
The environment will influence the communication disdance much.
