WLAN 802.11a/b/g/n/ac 4x4 MU-MIMO WiFi Traffic Generator supporting 1200 Virtual STA Interfaces.

The CT524 wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The CT524 uses a modified Wireless driver for WiFi NICs based on the Qualcomm/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 64 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 ath10k a/b/g/n/ac 4x4 MU-MIMO and one ath9k a/b/g/n WiFi radios per CT524 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 /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 and 802.11AC, configuring the MCS rates also determines the number of spatial streams (1x1, 2x2, 3x3, 4x4, 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).
