CT522-128 LANforge WiFIRE Chromebook 802.11a/b/g/n WiFi Traffic Generator with 128 Virtual STA Interfaces
The CT522-128 wireless traffic generator is an excellent choice for testing Access Points
and other WiFi networks. The chassis is a Chromebook with single WiFi radio.
The radio's max theoretical speed is 450 Mbps (3x3 MIMO). The CT522-128
uses a modified Wireless driver for WiFi NICs based on the Atheros chipset. It
can support up to 128 Virtual Stations. 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 have a WEP (64 or 128bit)
or WPA/WPA2 key assigned. The radio supports 802.11 a, b, g or n mode.
The radio's frequency and Tx-Power can also be configured.
There is a single WiFi radio per CT522-128 but multiple CT522-128 systems or any other CT52x systems can
be clustered together for more realistic radio interference patterns and increased
traffic generation capability. Clustering and management can be performed over
an auxiliary 2.4 GHz 802.11 b/g/n USB WiFi NIC (as shown in picture) as well as the
built-in Ethernet port.
All virtual stations must be on the same frequency, but as long as the protocol
supports that frequency, 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, or n. If
the radio is on a 5Ghz channel, the stations can be a or n. The bandwidth can be
configured for all protocols. For 802.11n and 802.11AC, configuring the MCS rates also determines
the number of spatial streams (1x1, 2x2, etc).
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 CT522-128 will fit into standard laptop carrying cases
for easy portability. No additional hardware or software is required, but you may wish
to manage the system using the LANforge GUI on a separate machine.

Quick Start Guide
- Connect Management Ethernet port to Management network or management PC. If
connecting directly to a PC, an Ethernet cross-over cable should be used.
- 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.
- The Client side of the network will be the Virtual Stations configured on the
CT522-128 WiFi NIC(s).
- Connect power to standard US or European AC power source. If using external
battery pack, then connect to that instead.
- 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 CT522-128 appliance has a web
server that also provides the LANforge GUIs.
- The CT522-128 should now boot. If DHCP is enabled on the Management network,
the CT522-128 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.
- Start the LANforge-GUI on the management PC and click the 'Discover' button.
It should find the CT522-128 appliance and add the IP address to the drop-down
box in the Connect widget. Press 'Connect' and you will be connected to
the CT522-128.
- 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
WPA/WPA2 password (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 128 Virtual Station interfaces
per CT522-128 with the 'Create' button.
- 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.
- Any GUI modifications take place immediately after you click 'Submit'.
