“iperf –c <IP address of Server PC> -w 65535”
See Figure 102.

This will run a test over the Wi-Fi link to the server PC and report back results as seen in Figure 103. These
results show the bandwidth (throughput) of the test as 16.2 Mbits/sec.

4. Using the theoretical throughput calculations in the following table you can compare the results with the
measured to give an indication of the difference between expected and measured. Keep in mind that the
theoretical calculations are best-case possible results.

In the command line for the client mapping you established the server IP address followed by the –w 65535,
where -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. Figure 105 provides
an example where the same test is run for 30 seconds.
