Throughput Test
The performance of a wireless link is best measured in terms of the maximum throughput that can be achieved. The
recommended method of measuring throughput is with the "Iperf" utility. Iperf has client and server functionality,
where the server waits for a client connection. For wireless links, it is recommended that Iperf throughput testing is
performed on point to point links while the remainder of the wireless network is inactive (i.e. not sending any data).
Iperf is built into the modems for convenience, and allows measurement of TCP throughput with default Iperf
parameters. The internal Iperf utility always gives a lower result than running Iperf externally because of the additional
load placed on the internal microprocessor. Even so, the throughput results still gives an excellent indication of link
performance as long as you compare the measured result against the expected result in the table. See Appendix D -

Iperf Throughput for details on running this application externally.
Internal Throughput Test
Before testing ensure that the end node of the Wi-Fi Link that you wish to test has the Iperf Server enabled under the
Advanced Radio Settings page and Saved to Flash and the module has been reset. See 3.9
