Cisco WLAN Passpoint Configuration Guide
Last Updated: December, 2014
Overview
The purpose of this document is to describe the necessary set-up procedures for demonstrating an
automated network discovery and connection using WiFi Alliance Passpoint Certified Access Point and
client devices. Using this document’s instructions, you will be able to configure Cisco APs/WLCs as
Passpoint 1.0 certified system. Access Points (APs) and phone client devices that are certified for WiFi
Alliance’s Passpoint 1.0 specification are able to work together providing the functionality listed in this
document. This is achieved by AP which supports IEEE 802.11u-based network information and the
phone client device that gathers necessary information by using Access Network Query Protocol
(ANQP) messages.

The 802.11u enabled phone client devices discover and select target AP based on the information
gathered during the pre-association stage from an 802.11u-enabled AP/Wireless LAN Controller
(WLC). A phone client device has pre-provisioned network information such as home OI Information,
realm name and domain name, presented as configuration file inside the phone client device. In addition,
the phone client device may obtain home network information using the IMSI data derived from the
inserted SIM/USIM card.

The 802.11u AP provides various information listings that provide the HotSpot owner details, roaming
partners, realm list, 3GPP cellular information, and domain name. The realm list also provides listings
of the realm name and its associated EAP authentication type mappings. Knowing this information is
essential for the phone client device so that correct EAP credential exchange may take place.

Currently, there are many WiFi Passpoint Certified devices, such as Samsung Galaxy-S4 and Intel
Centrino 6230 WiFi chipset, and various types of phone client devices. This document uses Galaxy S4
(OS v4.2.2) as the device to demonstrate a “Wi-Fi CERTIFIED Passpoint” device, as well as an iPhone
5 running iOS7 to demonstrate its configuration according to the Wi-Fi Alliance Hotspot 2.0
Specification.

The procedures described in this document provide a means of demonstrating the advantage of a
seamless authentication process between the Passpoint supported phone client device and AP in an intra-
or inter-operator roaming environment. Through this hassle free process, an end user will experience the
same ease of use regarding network connectivity as is present and expected with 3G or cellular-based
services.
