A quick presentation about Funet WLAN roaming, eduroam in Finland and about Wireless Tampere, which is based on eduroam architecture and technologies. The presentation also contains a short clip from my Terena Networking Conference 2010 presentation about the implementation and the future development of the Finnish Top Level RADIUS roaming server.

2. eduroam today around the world

3. History in Finland
• Funet WLAN Roaming idea
presented first in Autumn 2002 by
TUT DCE at Funet Tech. Days
• Cooperation with CSC led to
working with Terena Mobility from
2003 onwards => first eduroam
tests (NL, FI, PT, CR, UK)
• Terena Mobility work in TUT DCE –
CSC project
• Funet WLAN Roaming and
eduroam Finland to production
service in 2004.

5. Work done
●
A lot of practical architecture and concept development as well as
lobbying, meetings and presentations

Radius-based Public Access Roaming in the Finnish University
Network (FUNET) (PDF), paper presented in the Terena Networking
Conference 2003, Zagreb, Croatia.

6. Funet WLAN Roaming /
eduroam Finland
●
RADIUS based Wi-Fi roaming since 2002, since 2004 in
production use
●
Together with eduroam(tm) Finland the center for Finnish
education and research roaming
●
About 50 realms, roughly 88000 roaming authentications /
year, over 1000 access points in educational institutions
●
Roams with Wireless Tampere and Sparknet community
networks, open for other roaming partners and roaming
research as a part of ICT SHOK Future Internet Testbed

7. Wireless Tampere community
network
●
a cooperative open wireless community network for
companies, consumers, education and research institutions
●
based on the RADIUS based eduroam(tm) technology for
roaming
●
58 realms, 44220 roaming authentications/year (2009), all
major cities and education institutions at Tampere region,
roughly 900 access points (most of them in public places)
●
participates already in Funet WLAN roaming, interested to
roam with also other municipal, community and commercial
Wi-Fi networks

Future directions
• Encouraging organisations to adopt RadSec =>
do not even have to run Radiator, there exists
open source proxy solution radsecproxy from
UNINETT
• Able and willing to test DNS based discovery or
RadSec in general but in search for partners
• Would really like to see DNS based peer-to-peer
roaming replacing hierarchical model and inter-
federation roaming between commercial and
academic worlds
