Diagram 8 RF Path Loss
Example: one pairs of ZA-5000-I, the space between bridges is 3km.
Tx Power ＝ 18dBm
Cable loss ＝ 1dBi
Antenna Gain ＝ 23dBi
Path loss ＝ 116dBm
Local receive signal strengthens（dBm）＝ 18－1＋23－116＋23－1 ＝ －54（dBm）
Q 4. Why the throughput is not high?
You should adjust antenna to get highest signal strengthens. if can not get higher signal
