Can you explain what the following is on Throughput Test

[ 3] local 192.168.156.254 port 46863 connected with 192.168.156.19 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0- 5.0 sec 28.9 MBytes 48.5 Mbits/sec
[ 3] Sent 20226 datagrams
[ 3] Server Report:
[ 3] 0.0- 5.5 sec 17.2 MBytes 26.2 Mbits/sec 15.055 ms 8237/20227 (41%)

What does the 48.5 Mbits/sec value mean?
What does the 26.2 Value mean?
What is the 41%?

By the way the SM is 3mi from the tower and the following:
156
00:04:56:c1:4b:56
5835 MHz
20 MHz
28 dB
-67 dBm

Tom,
To answer your question:

What does the 48.5 Mbits/sec value mean?
It is the rate at which iperf Client is sending the data.

What does the 26.2 Value mean?
It is the avg. receive data rate at Server, at the end of test duration.

What is the 41%?
It is the packet loss %, at the end of test duration

We recommend that you not use provided throughput test from within the GUI of the AP. This uses processing power from the radio to perform the test which affects the accuracy of the data from the internal test. A more accurate test would be to use iperf between a PC above the AP and PC below the Station.
