WISPr
and the Ruckus Wireless ZoneFlex
A first step toward standardizing
hotspot
authentication WISPr is a protocol
from the Wi-Fi
Alliance that allows users to roam
between wireless
internet service providers. WISPr
addresses how to
authenticate users via the Universal
Access Method
(UAM), a browser-based login at a
captive portal
hotspot. It requires that RADIUS
be used for AAA
and defines the required RADIUS
attributes.
Once redirected, users are presented
with a terms
and conditions page. This information
is then
passed back to the RADIUS server
through the
ZoneFlex 2942. Upon successful authentication,
the Ruckus ZoneFlex 2942 redirects
the user to
HarborLink’s SmartSpot engine,
a service platform
that provides accounting, advertisement
and
content insertion.
Constant communication between the
ZoneFlex
2942s, using WISPr, and the remote
RADIUS server
tells the AP the status of each client
session. DOWNLOAD
THE COMPLETE WHITE PAPER
WISPr and the Wi-Fi Alliance
WISPr was chartered by the Wi-Fi
Alliance to describe the recommended
operational practices, technical
architecture, and Authentication,
Authorization, and Accounting (AAA)
framework needed to enable subscriber
roaming among Wi-Fi based Wireless
Internet Service Providers (WISPs).
This roaming framework allows using
Wi-Fi compliant devices to roam into
Wi-Fi enabled hotspots for public
access and services. User can be
authenticated and billed (if appropriate)
for service by their Home Entity
(such as another service provider
or corporation).
In order to facilitate compatibility
with the widest possible range of
legacy Wi-Fi products, it is recommended
that WISPs or Hotspot Operators adopt
a browser-based Universal Access
Method (UAM) for Public Access Networks.
The UAM allows a subscriber to access
WISP services with only a Wi-Fi network
interface and Internet browser on
the user’s device.
RADIUS is the recommended backend
AAA protocol to support the access,
authentication, and accounting requirements
of WISP roaming. This document describes
a minimum set of RADIUS attributes
needed to support basic services,
fault isolation, and session/transaction
accounting.

WISPr
Deployment Around the World
According to
research, on average 58 per cent
of ISPs already have a network that
is fully compliant with the WISPr
(Wireless Internet Service Provider
roaming) specification that aims
to facilitate simple, one-click access
to wireless hotspots. Of those whose
network is not compliant, 60 per
cent plan to do so within 12 months.
However, this figure masks some substantial
discrepancies. In Europe a far higher
number are committed to WISPr, with
67 per cent being fully compliant
compared to only 42 per cent in the
US and 44 per cent in Asia.
"We are delighted the research shows
that WISPr has been fully adopted
by so many operators in Europe. The
specification is all about removing
the burden of connecting from the
end user and providing them with
the customer experience they want
- fast and easy connectivity. In
fact, our HotSpotter software shows
the benefits of being compliant with
WISPr. Our end users can connect
to any of our hotspots with a mere
click of a button! On the operator
side, it will make it easier for
operators to establish roaming agreements
with one another. Both of these factors
will help increase usage, so it is
in everyone's interest for operators
to become compliant. It is a shame
that in regions such as the US and
Far East, at present, many operators
don't really know enough about WISPr
or understand the benefits," concludes
Jan Streefland, managing director
and co-founder of Trustive, and international
wireless hotspot access provider.
[Note: At Connect802, we're pleased
to be one of the few Wi-Fi integrators
in the United States that has WISPr
expertise and that brings that expertise
to the marketplace in a "productized"
form: the FREEPASS service!

The
WISPr Technical Specification
This
is the WISPr attribute documentation
presented here for more technically-oriented
readers. Individual vendor implementations
of the WISPr protocol differ but
the goal is to allow "across-the-Internet"
connectivity and roaming for HotSpot
access points.
