  1. In Pursuit of Carrier WiFi A Light Reading Webinar Sponsored by

  2. Today’s Presenters Gabriel Brown Senior Analyst, Heavy Reading Danielle Russell Marketing Director, Alepo Matt MacPherson Board Member, Wireless Broadband Alliance

  3. Agenda Introduction – Towards Carrier WiFi (Heavy Reading) Commercial Drivers for Hotspot Services (Alepo) Next-Generation Hotspot Initiative (WBA) Summary

  4. WiFi in the Smartphone Era Connections to AT&T’s Hotspot Infrastructure Source: AT&T • Between 25% and 50% of smartphone data usage is via WiFi • Based on data volume, time, number of sessions, and so on

  5. Towards Carrier WiFi Phases of WiFi Offload • Offload • Hard offload • User-driven • Unmanaged • Optimize • Auto-login • User identity • Secure • Integrate • Session mobility • Policy-driven • Service transparency 2014 2010 2012 • WiFi has come in from the cold; it is becoming part of mainstream operator-thinking • WiFi integration is user- and services-led; it is not primarily about cost reduction • Ultimately WiFi will be considered a trusted access network on a par with the 2G/3G/LTE RAN

  6. Integrating WiFi into a Cellular Environment? How to decide which network to attach to? How to make operator services available on WiFi? How to integrate with the core network? Operator Services HSPA EPC Router LTE Internet Services • Some services *only* available through the operator core • Core network not aware of radio access conditions • Will ANDSF, policy & NGHI help bridge these gaps? • Device is best-placed to understand local radio conditions; but • May not know which APs it has permission to access • May not know the prevailing performance of each access type WiFi Internet

  7. The Wild West of WiFi Adaptability of WiFi creates diversity of implementation Managed Hotspots are the focus of attention Are Hotspots enough to make a real difference?

  8. Poll Question #1 How important is it to your choice of mobile provider that your smartphone tariff includes bundled WiFi access? Not important at all; I prefer WiFi to be separate Valuable at the margins, but not especially important An important factor, but not decisive Very important; a “must-have” feature

  9. Commercial Drivers for Operator Hotspot Services

  10. Who’s at Your Hotspot? Non-Subscribers Your Existing Subscribers On What Device? SIM Enabled Wi-Fi Only SIM + EAP Enabled Wi-Fi Only How Do They Access Wi-Fi? Web Portal Offload How Frequently? Wi-Fi Subscription User ID / Password One-Time Data Pass Unlimited (Free or Add-On) Counted in Data Cap Charging Options How Do They Pay? Credit Card Voucher Mobile Account Premium SMS

  11. Mobile Data Offload • Objective: • Increase capacity and optimize network resources • Challenges: • How to ensure that subscribers actually utilizing Wi-Fi Hotspot services? • Core Components & Functions: • Automatic EAP Authentication • Wi-Fi to Mobile Authentication Gateway • Pre-Provision SSID in Mobile Devices • Mobile Device Management

  12. Wi-Fi Hotspot Monetization • Objectives: • Generate New Revenue Stream on Wi-Fi Hotspot Network • Offset Investment in Wi-Fi Hotspot Infrastructure • Reach a Broader Audience of Customers, incl. non-subscribers, internet only • Sample Business Plans for Monetized Wi-Fi Hotspots:

  13. Wi-Fi Hotspot Core Network + Mobile Core Integration

  14. How to Grow a Wi-Fi Hotspot Network: MTN Case Study • Tiered Wi-Fi Hotspot Network Model • Facilitates Rapid, Cost-Effective Expansion of Wi-Fi Hotspots • Centralizes All Wi-Fi Hotspot Management • Leverage Partners & Resellers to Set Up Hotspots and Revenue Share

  15. Emerging Wi-Fi Use Cases for Mobile Operators

  16. Poll Question #2 • What is the biggest barrier to integrating WiFi into mobile operator service portfolios? • It is hard to get a large enough WiFi footprint to make a real difference to most users • It is hard to get a consistent device implementation and so difficult to market and support • The back-end tools to mange provisioning and billing of devices are not mature enough

  17. Next-Generation Hotspot Initiative

  18. WBA an Unique Experts Group WBA was founded in 2003 by a unique mix of Wi-Fi, mobile and broadband network operators who viewed public Wi-Fi as a strategic complement to other networks (3G/UMTS, CDMA, WiMAX, Cable, xDSL etc).  Focused on enabling global Wi-Fi roaming Key enablers & strong expertise in Wi-Fi based services StrongOperatorHeritage& EcosystemEngagement

  19. Global footprint of 290,000+ hotspots Collective user base of 360 million+ subscribers

  20. The Problem… Macro2G/3G/4G 26x Growth 1000 Macro Capacity 100 Growth 10 Spectrum 1 Consumer Business Community 1990 1995 2000 2005 2010 2015 Wi-FiFemto Source: Agilent • Overall Capacity Not Keeping Pace with Data Demand • Small Cells Increase Existing Capacity

  21. The Barriers… • Top barriers to wider implementation of Wi-Fi roaming: • Top barriers to further adoption and usage of Wi-Fi: • Network discovery, identification, connection, authentication and security all key for seamless integration of Wi-Fi and cellular

  28. Summary WiFi is now a core part of the smartphone user experience Operators are evaluating how to attract and retain customers through integration of WiFi in their service portfolios and networks Managed hotspots are the most viable starting point because of the ability to influence service quality and monetize usage The Next-Generation Hotspot Initiative makes an important contribution towards making WiFi a carrier-class technology Potential for WiFi to be considered a trusted access network on a par with 3G or LTE
