TeliaSonera tests SIM card roaming for a simpler and safer W-LAN

During 3GSM World Congress in Cannes, TeliaSonera presents as the first
operator in the world, testing of SIM card-roaming in W-LAN networks.
The type of SIM card used in mobile phones could become the standard for
identifying users of wireless W-LAN services such as TeliaSonera's
HomeRun. TeliaSonera has recently carried out a successful testing of
this new technology between networks in Sweden and Finland.

Roaming between two W-LAN operators who use SIM card authentication
where operators have different W-LAN systems and different system
suppliers was tested.

Today W-LAN network users are identified by user names and passwords.
The new SIM card standard would benefit both the users and operators by
providing a simpler and safer method for logging in, enabling joint
subscription and invoicing of GSM/3G and W-LAN, offering improved
roaming capabilities between different operators, and by providing
effective solutions for combined multi access (W-LAN, GSM, UMTS)
systems. The SIM card solution, based on the security protocol 802.1x
and the standard EAP-SIM, can be employed as soon as the GSM Association
has accepted and recommended the standard for its members to be used for
SIM card based logging-in within one's network and roaming between other

The SIM card can be placed into a computer either via an adapter in the
computer´s PC card holder or via an adapter attached to the computer's
PC card slot.

TeliaSonera will demonstrate this new technology with roaming via EAP-
SIM in TeliaSonera´s Press Room in Palais des festivals at the 3GSM
World Congress in Cannes, February 23-25.
