 I'm very happy to welcome the public of the ITU telecom world in Busan for visiting the joint ITUR and ITUD pavilion. Concerning the ITUR pavilion, I mean the part of this pavilion which relates to ITUR activities, this exhibition shows the role of the ITUR sector in shaping the global ecosystem for regular communications which includes mobile broadband, satellites, television broadcasting and many other services which make our life easier and more pleasant and more efficient as well and the role of the radio sector of the ITU, the ITUR is to develop international regulations and global standards which enable huge economies of scale and worldwide interoperability and roaming of equipment. So we are this year celebrating the 90th anniversary of the ITUR study groups which started their work in 1927 contributing by their studies to enable new technologies as they were appearing in radio communications to be implemented in networks and equipment so that we have built over these 90 years a globally harmonized ecosystem which is sustainable and I think the longevity of the system is also highlighting the sustainability of what is produced by the ITUR process So today we are working on 5G, we are working on many new technologies in satellites and balloons and drones and if you visit this joint pavilion of ITUR and ITUD you will be able to see how in the last 90 years the ITU has been shaping the global ecosystem for regular communications The public at ITU Telecom World will also see this joint pavilion exhibition of members of the ITUR and ITUD sector to present their realizations, their achievements in past years as members of ITU
