  9. 9. Key carrier Wi-Fi requirements ▪ Great connectivity in challenging environments (high client density, pervasive interference, NLoS) ▪ Seamless subscriber experience (authentication first, session continuity later) ▪ Clean, efficient integration into existing mobile core entities / data plans / marketing RUCKUS WIRELESS PROPRIETARY AND CONFIDENTIAL 9
  11. 11. Clarity▪ Radio performance matters more than ever (high density, interference, ubiquity)▪ Conventional approach (70-90% of the market): off-the-shelf Wi-Fi chipset + reference design implementation + nice marketing about channel changing▪ Result: Pervasive view that Wi-Fi is flaky and mediocre (50% of Cisco’s customers report dissatisfaction with radio performance. The other 50% don’t know what they’re missing.)▪ It doesn’t have to be like that RUCKUS WIRELESS PROPRIETARY AND CONFIDENTIAL 11

  29. 29. A word on Hotspot 2.0 ▪ WBA operators angling for better control and seamless user experience with Wi-Fi + cellular ▪ Recognition that Wi-Fi Alliance is the best place to get handset & infrastructure changes made ▪ Hotspot 2.0 initiative launched in 2010 ▪ First, most straightforward step is implementation of 802.11u, enabling AP to client communication about available services ▪ Next steps will be more challenging: ▪ common framework for policy definition and provisioning — where does this get worked out? ▪ UE hand-off behavior within Wi-Fi networks (what the Wi-Fi community calls “roaming”) ▪ operator control over UE hardware ▪ application-specific selective offload RUCKUS WIRELESS PROPRIETARY AND CONFIDENTIAL 29
