Intel and Transat Demonstrate Standards Based One-Bill Roaming between WLAN Hotspots and WWAN

SIM Authentication is the leading authentication and billing solution in the cellular industry today, with almost 1 billion GSM subscribers around the world. The IETF EAP-SIM and Protected EAP (PEAP) standards allow notebook computers to use SIM to access WiFi hotspots. Network operators can offer enhanced revenue producing services with secure roaming to their customers using the existing GSM infrastructure enabled by Transat and Intel technology. In most cases today, users must manually enter usernames and passwords or credit-card information to access a public WLAN service. Users typically have several usernames to remember for different services and each service may have different logon procedures. With a notebook enabled with EAP-SIM/PEAP client software and a SIM module, the user can securely log onto an enabled public WLAN hotspot after entering a simple PIN and get a single bill from their service provider. For network operators, the use of SIM technology can provide a trusted, secure solution for authenticating users, verifying roaming relationships, and exchanging billing data with roaming partners. The Transat solution provides an intelligent connection enabling wireless and wireline carriers to intelligently add the access charges to your existing home, office, DSL or even your existing wireless bill. Transat delivers network software to integrate WLAN and wireless carrier networks for single point authentication and billing, without modifying the core network. Transat enables operators to deliver high speed Internet access via their own wireless LAN networks or those of third parties. WLAN operators now interconnect with the worldwide GSM subscriber base. Whether for public access or private networks, Transats uncomplicated approach liberates network design.
