Toni Stadelmann, Board Member of Comfone AG, graduated in Electrical Engineering in 1975. From 1975 to 1987 he held a number of management positions at Swisscom. After further extending his knowledge in the telecommunications industry and taking part in many mobile-service-related advanced training sessions, he took over various executive positions at Swisscom Mobile, including Head of Planning, Chief Technical Officer (CTO), Director of International Business and deputy Director.

From the very inception of the GSM standard in mobile communications, Mr. Stadelmann has been an active member in organisations associated with the international standardisation of GSM and its worldwide promotion. He played an important part in the foundation of the GSM Association and he was elected to the Executive Committee of the GSMA from 1996 to 2002.

The focus of his activities has been to make the implementation of worldwide roaming quicker and easier. Among other things, as chairman of the Inter-Standard Roaming Task Force he introduced the controlled opening of the GSM Association to roaming to other mobile standards, which with the formation of the GSM Global Roaming Forum represents an important milestone in the development of worldwide mobile communications.

It is Mr. Stadelmann's vision to achieve seamless, secure and open roaming between all mobile standards (GSM, 3G, WLAN, etc), bringing the entire industry to a new and profitable surge in development.
