DWL-7000ap Signal Strength

[Hristo Ganchev]

Hello, 
 
We have connected 2 access points using them for point-to-point connection 
 
info: 
Output power: 0.1W 
Frequency: 5.850Ghz
Tx antenna line loss:1-2dB
Tx antenna gain: 28dBi 
Path Length: 2.6miles
Rx antenna gain: no info 
Rx transmission line loss: 1-2dB
Rx Signal: no info 
Rx threshold: -73dBm
 
+)Device 1 has bigger and stronger antenna than device 2
+)Device 1 is higher than device 2.

Questions: 
 
1. What is the meaning of RxSignalStrength?
2. What is the meaning of AckSignalStrength?
3. How can I lower the amount of duplicate packets 
4. From the Tx and Rx values, can I draw conclusion for the aligning of the antennas? 
5. Is it possible one of the antennas to be aligned properly, but the other not, so I can get very high ratio of failed ack. packets and the transfer to be slow because of this issue? 
 
Thank you.
