CT520-abg LANforge WiFIRE 802.11a/b/g WiFi Traffic Generator with 32 Virtual STA Interfaces
The CT520-abg wireless traffic generator is an excellent choice for testing Access Points
and other WiFi networks. The CT520-abg
uses a modified Wireless driver for WiFi NICs based on the Atheros chipset. It
can support up to 32 Virtual Stations. Each of the
Virtual Stations has it's 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 ESSID and Nickname, and have a WEP (64 or 128bit)
or WPA key assigned. There is a single WiFi radio per CT520-abg but multiple CT520-abg systems can
be clustered together for more realistic radio interference patterns and increased
traffic generation capability. The radio supports 802.11 a, b, or g mode.
The radio's channel, frequency, sensitivity, rate, RTS and Tx-Power can
also be configured.
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 CT520-abg has no moving parts (other than the three removable external antenna on swivel mounts)
and will fit into a small travel bag or briefcase for easy portability.
It is also completely silent, so you can include it in your customer demos and presentations.
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 CT520-abg can also be managed over a serial console
in text mode or through directly connected VGA monitor and keyboard.

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
CT520-abg WiFi NIC(s).
- Connect power brick to standard US or European AC power source.
- 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 CT520-abg appliance has a web
server that also provides the LANforge GUIs.
- The CT520-abg should now boot. If DHCP is enabled on the Management network,
the CT520-abg 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 CT520-abg appliance and add the IP address to the drop-down
box in the Connect widget. Press 'Connect' and you will be connected to
the CT520-abg.
- 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 32 Virtual Station interfaces
per CT520-abg 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'.
