Phases of WiFi Offload
• 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

Operator Services
How to decide which network to
attach to?
How to integrate with the core
network?
•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
•Some services *only* available through the operator core
•Core network not aware of radio access conditions
•Will ANDSF, policy & NGHI help bridge these gaps?

• Adaptability of WiFi creates diversity of implementation• Managed Hotspots are the focus of attention• Are Hotspots enough to make a real difference?
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

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

Best practices guide for operators• Implement seamless
authentication over Wi-Fi networks based on NGH
• Transition from legacy to NGH networks
• Implement 3G/4G data offload over NGH networks
• Use lessons from past WBA seamless authentication trials & the NGH Trial
End-to-end “Real-World” Wi-Fi roaming trial to • Test & validate NGH
• Engage ecosystem including operators, equipment providers and roaming hub providers for end-to-end testing
• Provide detailed instructions for NGH based roaming lifecycle and feedback on the Wi-Fi Alliance specifications
NGH TrialNGH Operators Guide Joint Taskforce Cooperation Framework
Objectives:• Make WiFi-WiFi roaming
as easy and transparent as GSM
• Common technical implementation for 3GPP-WiFi interworking
• 3GPP-WiFi integration seamless and transparent to the customer
Objectives:• Have a complementary
focus and cooperation that maximizes the benefits of innovation for end users, manufacturers and service providers within the Wi-Fi industry
• Join effort to promote the benefits of WBA’s NGH program & Wi-Fi Alliance HS 2.0 program among the wide ecosystem associated with the Wi-Fi industryEnhancement to support NGH Roaming
Summary
