The CT523c-192-2ac2-1ac-10g-cu has one free slot to support additional NICs. Existing STA licenses may be used or additional STA licenses may be purchased (please contact sales for licensing options). The CT523c-2ac2-db-10g-cu wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The CT523c-2ac2-db-10g-cu uses a modified Wireless driver for WiFi NICs based on the Qualcomm/Atheros chipset. The ath10k (a/b/g/n/ac) chipset NICs can support up to 64 stations per radio.

 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 128 per machine).
• 802.11a/b/g/n/ac Wireless Station (up to 64).
• 802.11a/n/ac Wireless Station (up to 128 per machine).
• 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 CT523c-2ac2-db-10g-cu 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
