Wi-Fi is already built into all these devices and Hotspots are also

being used extensively by users globally!

…as part of the solution!!


The Opportunity The latest data confirms that

Data Offload and Enhance the user Experience are

the must importants benefits for operators More of 50% of smartphones data traffic is offload by

Wi-Fi for more then 10% of Operators

The Opportunity: Unstoppable Wi-Fi

Growth, role and significance of Wi-Fi

The Challenges: Industry Engagement User experience, offload and roaming








End User Devices

Widely available equipments

capable of performing

communications using the latest

Wi-Fi technologies

Information Systens

Operators to withdraw the

maximum potential Wi-Fi need to

have an integration of IS,

regarding provisioning,

authentication and billing.

Network

Implementation of technologies

that allow Wi-Fi to have a

seamless authentication to allow

the Offload.

The networks need to have

enough bandwidth and QoS to

delivery a powerfull experience.

Business Case

Operators must define a clear

strategy for the Wi-Fi, from a

business and technology point of

view

The Challenges How to improve the user experience over Wi-Fi Networks

Interoperability between Networks

The industry must come up with a common approach to address the interoperability

between networks and a framework to develop Wi-Fi international roaming.

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”

• Test & validate NGH

• Engage ecosystem

equipment providers and

roaming hub providers for

Objectives:

• Make Wi-Fi-Wi-Fi

roaming as easy and

transparent as GSM

• Common technical

implementation for

3GPP-WiFi interworking

• 3GPP-WiFi integration

seamless & 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

Our Work WBA NGH Trial: Conclusions

Approximate 25% of the operators actually deployed the NGH

in their existing production network

802.1x protocol for radio link security, EAP-SIM for

authentication and 802.11u for network discovery & selection -

we get an automatic & trusted connection

We bring security and cellular experience to the end customer

• Make Wi-Fi to Wi-Fi Roaming as easy and transparent

as 3GPP roaming, leveraging GSMA experience;

• Define and deliver a common technical implementation

for 3GPP to Wi-Fi interworking for both devices and

networks;

• Ensure 3GPP to Wi-Fi integration is as seamless and

transparent as possible to the customer;

• Promote relevant activities across GSMA and WBA

participants and foster greater awareness in the

different geographic regions around the world;

• Identify gaps in available standards and make

recommendations to address gaps;

• Identify the guidelines and recommendations to GSMA

and WBA member companies to accelerate the Wi-Fi

Roaming solutions based on jointly agreed

requirements and standards.

Objectives In April 2011, GSMA and

WBA formed a joint taskforce

to address Wi-Fi Roaming,

with the intention to bring

together the Wi-Fi and

cellular ecosystems in a

collaborative effort

Kick-off of the

Joint taskforce

WBA-GSMA

Project Roadmap

Achievements

• The joint taskforce had 33 companies from

both organizations participating actively on the

creation of a Roaming Whitepaper.

• All topics identified on the scope of the work

were address and the way of moving forward

was reached.

• From the Roaming Whitepaper were created

41 recommendations for both organizations to

update its specs, guidelines and

recommendations to improve Wi-Fi roaming

and 3G Offload.

Summary

Conclusion

Our Work GSMA-WBA Taskforce: Conclusions

Conclusions

• The Roaming Whitepaper identifies gaps and

requirements to be addressed in GSMA & WBA

• Some topics should be liaised to WFA and 3GPP

• The Wi-Fi Roaming Whitepaper identifies the

‘best practices’ that exist currently for Roaming

and recommends that additional work is required

to allow these practices to be transferred into Wi-

Fi Roaming.

• Following the completion of the Whitepaper,

GSMA and WBA will continue to work

collaboratively
