Director of the Radiocommunication Bureau (BR)

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​"Telecommunications/ICT are a key enabler to achieve the Sustainable Development Goals (SDGs) and to build a world where social, economic, environmental, and technological development is sustainable and available for everyone, everywhere. Technologies such as mobile communications, the Internet of Things, connected cars and cities, the fourth industrial revolution and artificial intelligence, all depend on telecommunication networks, services and applications, and increasingly rely on radiocommunications to provide the basis for ubiquitous connectivity. The ITU Radiocommu​nication Sector plays a vital role in this ecosystem: managing frequency spectrum and satellite orbits, as well as developing globally harmonized regulations and standards, are fundamental in order to ensure accessible and affordable telecommunications to all."
