This will run a test over the Wi-Fi Link to the Server PC and report back results as seen in Figure 3.
These results show the Bandwidth (Throughput) of the test as 16.2Mbits/sec.
Figure 3
Using the Theoretical throughput calculations in Table 1 you can compare the results with the measured to give an
indication of the difference between expected and measured. Remembering that the theoretical calculations are best case

Table 1
In the command line for the Client mapping we established the Server IP address followed by the –w 65535, -w is the
window size and the maximum TCPIP window size is 65535 bytes.
Another entry that can be added is –t <seconds> to run the test for a specific time period. Example of this is in figure 5
where the same test is run for 30 seconds.
