Make connecting to Wi-Fi services as easy, seamless
and secure as todays 3G cellular experience
The challenge
Today
Connecting to a Wi-Fi hotspot is completely manual Login process tedious, error prone
No consistent roaming between networks
Many steps to gain Internet access
Difficult to connect to Web portal with phones
Carriers lose opportunity for their roaming polices
to affect network selection
Tomorrow
Device and network negotiate capabilities Device auto selects best Wi-Fi network
Users do nothing
Policies pushed to phone
New revenue source for carriers
Carriers gain opportunity for their roaming
polices to affect network selection

The solution The industry has come together on a plan calledHotspot 2.0 (WI-FI CERTIFIED PasspointTM)
Release 1
Allows an AP to advertise capabilities pre-association
Capabilities include roaming arrangements amongst other
things
Supports seamless authentication via 802.1x
Standard complete
Release 2
Automate the process of configuring EAP on the device Download an operator policy
Introduce support for non SIM-based devices
Standard will emerge in mid 2013
802.11u, HotSpot 2.0 and Next Gen HotSpots

ORGANIZATION INITIATIVE DETAILS
IEEE 802.11U
IEEE standard published in Feb. 2011 Used to enable faster (automated) discovery and
selection of Wi-Fi APs
Required on APs and mobile devices
Wi-Fi
Alliance
HotSpot
2.0
Capabilities including enhanced discovery and
automated device provisioning that enables a
3G type experience for Wi-Fi users
Certification program driven by the Wi-Fi Alliance
Leverages 802.11u and adds extensions
Covers SIM and non-SIM devices (e.g. laptops),
utilizes 802.1X as the core authentication protocol
Wireless
Broadband
Alliance
(WBA)
Next
Generation
Hotspot
(NGH)
WBA operator trials to develop a commoncommercial technical framework for interoperability
across networks, technologies and devices.
Leverages HotSpot 2.0, 802.11u and adds
extensions

How it 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 todetermine what providers are
supported, capabilities of the
AP, etc.
4. AP responds to ANQP query
with requested information
5. Device compares provisioned
profile information against
HS2.0 data from APs and
associates to the best BSSID
