  • 89. Signal Strength – Great in both terminals for both tests Guangzhou Terminal B216 Beijing Terminal 1 RSSI indicated that both terminals had strong signal levels!
  • 90. 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!
  • 91. 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
  • 92. The Result - Guangzhou 802.11 n AP deployed by carrier
  • 93. The Results – Beijing - PEK New version of 802.11n AP deployed in PEK
  • 94. WaveTest - Application Results Guangzhou • 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

WaveAgent™ Small SW utility loaded on remote client WiFi Eco-system traffic Ethernet 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
  • 111. 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 UDP throughput, TCP Goodput, Loss Voice MOS and R-Value All results compared to user defined Service Level Requirements (SLRs)
