CT523-232-1ac-1n Expandable LANforge WiFIRE 802.11a/b/g/n/ac 2 radio WiFi Traffic Generator Supporting 232 Virtual STA Interfaces

The CT523-232-1ac-1n has a free slot to add an additional /ac or /n radio. Existing STA licenses may be used or additional STA licenses may be purchased (please contact sales for licensing options). The CT523-232-1ac-1n wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The CT523-232-1ac-1n uses a modified Wireless driver for WiFi NICs based on the Atheros chipset. The ath9k (a/b/g/n) chipset NICs can support up to 200 stations per radio. The ath10k (a/b/g/n/ac) chipset NICs can support up to 32 stations per radio. Each of the Virtual Stations has its own IP address, IP port space, MAC address and routing table. The Virtual Stations can be assigned to communicate to a particular Access Point, use a particular SSID, and Open or WPA/WPA2 authentication assigned. More advanced 802.1X authentication is also included. Each radio can be configured idependently of the other. Transmit power and channel/frequency is configured on a per-radio basis. Most other settings are configurable per virtual station.

There are one ath10k a/b/g/n/ac and one ath9k a/b/g/n WiFi radios per CT523-232-1ac-1n and multiple LANforge systems can be clustered together for even more realistic radio interference patterns and increased traffic generation capability.

All virtual stations on the same radio must be on the same frequency, but as long as the protocol supports that fequency, the multiple protocols can be used concurrently. For instance, if the radio is configured for a 2.4Ghz channel, the stations can be /b, /g, /n, or /ac. If the radio is on a 5Ghz channel, the stations can be /a, /n or /ac. The bandwidth can be configured for all protocols. For 802.11n, configuring the MCS rates also determines the number of streams (1x1, 2x2, 3x3, etc.).

NOTE: ath10k 802.11ac radios and stations may be more limited in rate selection and other features for the initial release.

The Virtual Stations may be configured with all of the virtual interfaces on the same subnet, or different subnets, depending on the testing requirements. When used with something like VoIP, it allows all of the VoIP calls to use the standard IP ports (with one call per virtual interface).

The CT523-232-1ac-1n has no fans and is silent. It has 6 antenna. It will fit into a small travel bag or briefcase for easy portability. No additional hardware or software is required, but it is suggested that you manage the system using the LANforge GUI on a separate machine. The CT523-232-1ac-1n can also be managed over a serial console in text mode or through directly connected monitor, mouse and keyboard.

Quick Start Guide

  1. Connect Management Ethernet port to Management network or management PC. If connecting directly to a PC, an Ethernet cross-over cable should be used.
  2. Connect eth1 wired Ethernet interface to wired Ethernet interface on the AP or network under test. This usually is considered the 'server' side of the network.
  3. The Client side of the network will be the Virtual Stations configured on the CT523-232-1ac-1n WiFi NIC(s).
  4. Connect power brick to standard US or European AC power source.
  5. Install the LANforge-GUI on a separate management PC or Laptop. Windows and Linux GUIs are supported: Select the correct one from the CDROM or Candela Technologies Download page and install it. The CT523-232-1ac-1n appliance has a web server that also provides the LANforge GUIs.
  6. The CT523-232-1ac-1n should now boot. If DHCP is enabled on the Management network, the CT523-232-1ac-1n will automatically acquire an IP address. If DHCP is not available, the IP address will be set to 192.168.1.101 by the LANforge scripts.
  7. Start the LANforge-GUI on the management PC and click the 'Discover' button. It should find the CT523-232-1ac-1n appliance and add the IP address to the drop-down box in the Connect widget. Press 'Connect' and you will be connected to the CT523-232-1ac-1n.
  8. Select the Port Mgr tab in the GUI. Double-click on the device called 'wiphy0'. This is the Radio device, and should be configured for the correct, channel, country-code, etc. Next, select one or more of the Virtual Station interfaces and click 'Modify'. Enter the correct IP address information, SSID and WEP or WPA/WPA2 key (if Enabled). After applying these changes, the Virtual Station interface should associate with the AP and be ready to send traffic. You may create up to 232 Virtual Station interfaces per CT523-232-1ac-1n with the 'Create' button.
  9. Once the interfaces are configured correctly, you can click on the Layer 3, VOIP/RTP and other LANforge-FIRE related GUI tabs and configure/modify/start/stop particular traffic patterns that utilize the virtual stations and wired Ethernet interface. In most cases, you will want one of the FIRE endpoints to be on the wired interface and the other to be on the WiFi Virtual Station interface. It is also valid to generate traffic between two Virtual Station interfaces. The GUI Plugins menu (and right-click on some tables) provides some plugins to do automated testing and reporting. Contact support if you have suggestions for improvements.
  10. Any GUI modifications take place immediately after you click 'Submit'.
