10. Setting up an Iperf Test
10.1 Required Equipment
• Two laptops with jperf installed. It is beyond the scope of this manual to cover the installation and
operation of these tools. The laptops must be on the same subnet but not necessarily the same
subnet as the radios (172.20.xx.yy). It is not required for the user to set a secondary IP address on
the radio to perform this test. It is recommended the iperf or jperf tests are first conducted
between the laptops using an Ethernet switch or cross-over Ethernet cable between them to
verify the laptops and iperf/jperf tools.
• Two or more StreamCaster radios properly configured.
10.2 Running Iperf Test
• Connect a laptop to one StreamCaster radio using the Ethernet cable.
• Connect the other laptop to another StreamCaster radio.
• Power up the radios and verify the radios are booted and connected wirelessly.
• At the receiver side type the following in a terminal
o iperf –s –u -i 1
• At the transmitter side type the following in a terminal
o iperf –c receiver_laptop_ip_address –u –i 1 –b 1M –t 60
