About the Author

Jean-Marc Chaduc was born in 1943. He is a graduate of the Ecole Polytechnique and of the Ecole nationale supérieure des telecommunications. His first professional activity was as the technical director of the early french satellite telecommunication center at Pleumeur-Bodou where he contributed to operate the first generations of satellites. Later he moved towards a more administrative career in different ministries where he has been in charge of promoting new radio networks. Then, at the Ministère de l'Industrie, he worked at the new legislation for telecommunications. In 1996, he was in charge of designing the new french Agence nationale des frequences and was appointed its general director from 1997.

Gérard Pogorel is Professor of Economics and Management at the Ecole Nationale Supérieure des Télécommunications, (ENST, Paris).Beforehand, he has acted as an evaluator, auditor, and reviewer for the NSF, Harvard Business Review, Research Policy and EU research programs in Information and Communications Technologies. He also has been a frequent member of government-level committees shaping spectrum policies in Europe and internationally, a member of monitoring committees (composed of independent experts) of the EU Framework Research Programme, Chair of the Monitoring Panel, Chair of the Monitoring Committee of the European Union Information Society and Technologies Research Programme.
