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

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 operators 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.
