Updated 20 Oct 2010: Clarify test setup
Ixia's IxChariot network peformance evaluation program is used with the test configuration shown in Figure 5 to run tests in each of the test locations. Testing is done using the SNB standard wireless test client, an Intel Wi-Fi Link 5300 AGN mini-PCIe card in a Dell Mini 12 running WinXP Home SP3.
Figure 5: Wireless test setup
All routers / APs are generally reset to factory defaults. On wireless routers, all testing is done on the LAN side of the router so that the product's routing performance does not affect wireless performance results, i.e. the Ethernet client is connected to a router LAN port.
At each test location, the IxChariot Throughput.scr script (which is an adaptation of the Filesndl.scr long file send script) is run for 1 minute in real-time mode using TCP/IP in both uplink (client to AP) and downlink (AP to client) directions. The only modification made to the IxChariot script is typically to change the file size from its default of 100,000 Bytes to 300,000 Bytes of data for each file send for 802.11g products and to 1,000,000 Bytes for draft 802.11n products.
