● Each VeriWave Stateful Client implements
� Carrier deference
� Collision sensing
� Random back-off
� Retransmission
� Collision emulation
● VeriWave client is a highly stateful entity
� Each client supports the full MAC per 802.11 standard
� 802.1X supplicant supports full EAP stack per client
� Upper layer protocols (e.g., DHCP and TCP) are also implemented using independent protocol state machines
� All state machines for all clients run concurrently
� Every client independently updates its state based on channel conditions e.g. 802.11g clients using protected-mode when .11b is detected
● Multi-level scheduler enables optimum channel utilization, multiple traffic flows per client, and mixing of Constant Bit Rate voice/video traffic with Best Effort data traffic

� Benefits• Enables performance testing of the client’s 802.11 subsystem (device driver and
integration) independently of the application
• Enables performance testing during silicon qualification (on eval boards), post driver integration on client hardware, and on integrated client during troubleshooting
• Works over any network interface (Ethernet, WLAN, MoCA, WiMAX, LTE, etc.)
• Allows testing to occur earlier in the development cycle
