7. New world of mobile networks
▪ Exponential traffic growth
▪ Linear capacity improvements —
AND not OR
▪ Wi-Fi now a peer to LTE in most
operators’ minds
▪ Subscribers now expect Wi-Fi
▪ Extensive mobile device support
▪ Wi-Fi infrastructure costs a small
fraction of incremental 3G or 4G
RAN
▪ Integrated multi-function devices are
a natural evolution

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

10. Great connectivity.

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

22. Industry roadmap
2011 2012 2013
Offloading what  packet data, via  (UE work happens  selective offload with
“hard offload” here) more operator control
Authentication  802.1x (EAP-modes)  more 802.1x, some
widely available now, I-WLAN
but limited use
Inter-RAT handoff  not a priority  discussing  implementation via
architectures xMIP or GTP
Back-end  limited; WLANs  802.1x-based  more sophisticated
integration usually still separate (primarily), fitting into functionality for HS2.0
existing mobile core support etc.
Hotspot 2.0  802.11u plugfests,  802.11u WFA certs  rolling out into hotspot
marketing  attending to higher networks and UEs in
layers and operator the market
control
MNO focus  thinking, budgeting,  getting started  more large-scale
RFIs (with notable deployments,
more-aggressive integration with LTE
exceptions) hetnets
Wholesaler focus  land grab for sites  establishing multi-
MNO integrations
Wi-Fi  3-stream APs  802.11ac

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

32. Roadmap
▪ 3-stream 802.11n + BeamFlex (including Tx
beamforming where it’s beneficial)
▪ 802.11ac with module upgrade
▪ Small cell backhaul for NLoS situations, with resilient
mesh connections, Wi-Fi optimized for low latency/jitter
▪ Multi-function small cell devices (LTE + Wi-Fi)
▪ More advanced mobile core integration models and
subscriber management functionality
