The CT522-264-1ac2-1n wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The CT522-264-1ac2-1n 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.

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.).

 1. Supports real-world protocols::

• Layer 2 : Raw-Ethernet.
• 802.1Q VLANs.
• PPPoE : Integrated PPPoE support.
• Layer 3 : IPv4, IPv6, UDP/IP, IGMP Multicast UDP, TCP/IP.
• Layer 4-7 : FTP, HTTP, HTTPS, TFTP, SFTP, SCP
• 802.11a/b/g/n Wireless Station(up to 200 per machine).
• 802.11a/n/ac wave-2 5Ghz Wireless Station (up to 64 per machine, one MU-MIMO per wave-2 radio).
• Layer 4-7 : TELNET, PING, DNS, SMTP, NMAP (via add-on script).
• File-IO : NFSv3, NFSv4, CIFS, iSCSI.

 2. Supports up to 1000 concurrent TCP connections with base license package.

 3. The CT522-264-1ac2-1n is able to push around 1.2Gbps using the 802.11AC wave-2 radio, depending on the protocols mix,

   wireless mode and environment, and speed of the network under test. Supports at least 60 VoIP (SIP, RTP) calls if appropriate licenses are purchased.    Performance results (this system performs similar to the CT523): Open, wave2 4x4 | TCP-DL-30sta-open wave-1 3x3 | TCP-DL-30sta-wpa2 wave-1 3x3
