CT521b-2ax4 Economy LANforge WiFIRE 802.11a/b/g/n/AC/AX 2 radio WiFi Traffic Generator Supporting 38 Virtual STA Interfaces
The CT521b-2ax4 wireless traffic generator is an excellent choice for testing Access Points
and other WiFi networks.
The 4x4 MTK7915 /AX (a/b/g/n/ac/AX)
chipset NICs can support 19 virtual 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 independently 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 two MTK7915 /a/b/g/n/AC/AX 2.4/5Ghz WiFi radios per CT521b-2ax4 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 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, /n, or /ax. If
the radio is on a 5Ghz channel, the stations can be /a, /n, ac, or ax. The bandwidth can be
configured for all protocols.
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 CT521b-2ax4 has no fans and is silent. It has 8 antenna.
It will fit into a small travel bag or briefcase for easy portability.
The system should be managed with the LANforge-GUI software installed on
a laptop or PC.
The CT521b-2ax4 can also be managed over a serial console
in text mode. Maximum throughput for the CT521b-2ax4 is about 1Gbps and is bound
by the relatively weak CPU. For faster systems, consider the CT522, CT523c,
and CT525 chassis.

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
CT521b-2ax4 WiFi NIC(s).
- Connect power to standard US or European AC power source. If using external
battery pack, then connect to that instead. Click button to power on the unit.
- The CT521b-2ax4 should now boot. If DHCP is enabled on the Management network,
the CT521b-2ax4 will automatically acquire an IP address. If DHCP is not available,
the IP address will be set to 192.168.1.101.
- Install the LANforge-GUI on a separate management PC or Laptop, or use VNC or remote-desktop
programs to access the LANforge system directly. Windows, MAC-OS and
Linux GUIs are supported: Select the correct one from the web page served from
the LANforge system and install it.
- Start the LANforge-GUI on the management PC and click the 'Discover' button.
It should find the CT521b-2ax4 appliance and add the IP address to the drop-down
box in the Connect widget. Press 'Connect' and you will be connected to
the CT521b-2ax4.
- 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 38 Virtual Station interfaces
per CT521b-2ax4 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 Chamber View window provides some automated test suites.
Contact support if you have suggestions for improvements.
- Any GUI modifications take place immediately after you click 'Submit' or 'OK'.
