What Is Roaming to Us? Current Situation

• Pass-One is concerned with end-user ie. authentication roaming, not with seamless handover between or within technologies/networks.

• No mobile operators offer WLAN services to roaming users based on SIM authentication

• Many service providers offer WLAN services to roaming users based on RADIUS proxying (esp. US)

• No multilateral roaming framework for WLAN based on any authentication method.
