LANforge-WiFIRE 802.11a/b/g/n dual-radio WiFi Traffic Generator supporting 400 Virtual STA Interfaces
TThe CT521-400 wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The CT521-400 uses a modified Wireless driver for WiFi NICs based on the Atheros chipset. It can support up to 400 Virtual Stations(Up to 200 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 ESSID and Nickname, and have a WEP (64 or 128bit) or WPA key assigned. There are two WiFi radios per CT521-400 and multiple CT521-400 systems can be clustered together for even more realistic radio interference patterns and increased traffic generation capability. Each radio can be configured idependently of the other, and supports 802.11 a, b, g or n mode. The radio's channel, frequency, sensitivity, rate, RTS and Tx-Power can also be configured.
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, 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, configuring the MCS rates also determines the number of streams (1x1, 2x2, 3x3 etc).
