Why Wi-Fi.


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


Does more. Costs less.

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


Great connectivity.


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 dissatisfactionwith radio performance. The other 50% don’t

knowwhat they’re missing.)

▪It doesn’t have to be like that


Radio performance innovation

▪Ample customer experience shows...

▪2x better range, capacity, reliability, and self-adapting autonomy

▪1/2 the capex and operating costs

Industry roadmap2011 2012 2013

Offloading what packet data, via “hard offload”

(UE work happens here)

selective offload with more operator control

Authentication 802.1x (EAP-modes) widely available now, but limited use

more 802.1x, some I-WLAN

Inter-RAT handoff not a priority discussing architectures

implementation via xMIP or GTP

Back-end integration

limited; WLANs usually still separate

802.1x-based (primarily), fitting into existing mobile core

more sophisticated functionality for HS2.0 support etc.

Hotspot 2.0 802.11u plugfests, marketing

802.11u WFA certs attending to higher

layers and operator control

rolling out into hotspot networks and UEs in the market

MNO focus thinking, budgeting, RFIs (with notable more-aggressive exceptions)

getting started more large-scale deployments, integration with LTE hetnets

Wholesaler focus land grab for sites establishing multi-MNO integrations

WSG architecture options


■ Massively scalable■ 10k APs, 100k clients, 2/20/40Gbps

throughput per gateway■ N+1 A/A clustering (distributed database)

for linear scalability

■ Mobile Internet gateway■ 3GPP WLAN Access Gateway (WAG), with integrated TTG/PDG option■ AAA Proxy, northbound datapath gateway and NMS/OSS API■ Flexible forwarding (local breakout or tunneling)

■ Mobility/caching services

■ WLAN controller/service gateway■ Wi-Fi EMS (capacity management, SLA monitoring and troubleshooting)

■ Controller services (RF, meshing, client load-balancing, …)

■ Auto-provisioning of SIM and non-SIM clients ■ Captive portal (local or WISPr)

■ HotSpot 2.0 / 802.11u

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


How HS 2.0 Works1. 802.11u-capable AP beacons

with HS2.0 support

2. Device probes with HS2.0 support

3. Device selects AP and performs ANQP request to determine what providers are supported, capabilities of the AP, etc.

4. AP responds to ANQP query with requested information

5. Device compiles provisioned profile information against HS2.0 data from APs and associates to the best BSSID

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
