93. IxVeriWave Turn up Process
● 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
97. Signal Strength –
Great in both terminals for both tests
Guangzhou Terminal B216
Beijing Terminal 1
RSSI indicated that both terminals had strong signal levels!
98. The Results – Beijing - PEK
Beijing only worked
for locations right
next to access point
This is a dropout of HTTP
The Results – Beijing - PEK
Some areas
have rates as
low as 4kbits
per second!
99. The Result - Guangzhou
Lowest HTTP goodput for
Guangzhou is 348Kbits/s
Greater Quality of
Experience in
Guangzhou – more
consistent application
performance in all
areas with no HTTP
dropouts

• Meets expected SLA
• Meets expected voice support
• Meets expected video support
• Meets expected data rates
Meets expected client mgmt
Beijing
• Poor overall performance
• Limited voice support
• No video support
• Poor in terminal roaming
• Very low data rates supported
• Poor client management

Benefits
Client hosting
WaveAgent
•
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
120. Part 3 – OTA Interoperability Testing
● Interoperability testing & troubleshooting with real client devices (laptops,
mobile phones, scanners, patient monitors, etc.)
● Powered by WaveAgent installed on each device
● Setup and test run within less than 5 minutes
● Results are reported over time
● WaveInsite measures
