PAGE 7
STA 1 2 3 2.3 Connecting to STA You can control the STA by connecting an Ethernet cable to one of its four LAN ports on the AP router or to a single LAN port on a dongle STA. 6 The CLI-based applications are run from the shell on the STA. The shell is accessible through any of the four LAN ports using telnet. The LAN ports’ default IP address is 192.168.1.253 with a subnet mask of 255.255.255.0. 7 Telnet login is “root” with no password. 4 5 8 2.3.

The AP can be configured using aniSdkTool, a CLI-based utility application. Note that many common broadband gateway functions are not included in this release (NAT, firewall, etc.). 3.2 AP hardware 8 One device in your hardware kit should be clearly labeled as AP.

1 2 3 4 5 4 Feature Configuration This chapter provides information related to configuring the client and AP for performance testing. 4.1 Configuring the AP AP configuration is accomplished via a telnet and CLI. 7 To telnet into the AP, use following commands at the Windows command prompt on the Agent PC: 8 1. Telnet 192.168.1.254. 9 2. The login is “root” (no password is required). 6 11 aniSdk Tool is a CLI that uses the Application Programming Interface (API) provided with the AP SDK.

Feature Configuration Command Description aniSdkTool –g rad Provides current channel and bandwidth information aniSdkTool –s chn 0 X Y 1 Sets the channel; channel X is the primary channel and Y is the secondary channel. Channel Y must equal X +/- 4; the primary channel will be used in 20 MHz mode, and for beacons and management traffic in 40 MHz modes.

Feature Configuration 1 4.3 Making the connection 4 The AP and STA both come configured with Open mode security (no security) and SSID set to Qualcomm. The user has to only clone MAC address of the device connected to the Qualcomm STA in order to get the link up and running: 5 1. On STA – iwpriv set_clone_addr 6 For example, iwpriv set_clone_addr 00:de:ad:be:ef:00 2 3 8 2.

1 2 3 4 5 Performance Test Configuration This chapter provides some guidelines for throughput performance testing of Qualcomm WCN1320-based reference designs. 5.1 Qualcomm recommendations for best performance 7 TCP/IP settings on systems sourcing and syncing data may impact throughput performance.
PAGE 14
Performance Test Configuration 1 5.3 Connecting wired device to AP and STA 4 The typical throughput test configuration is to have one wired device connected to the AP and one to the STA, and measure throughput between the two wired devices. These devices can be PCs, STBs, etc. 5 Figure 5-1 shows how to connect the wired device to the AP and STA.

Qualcomm tests extensively with two of these tools: Chariot (available for purchase from Ixia) and IPerf (free). Configuration considerations for each are provided below. 5.4.
