ITU Journal: ICT Discoveries, Vol. 2(1), December 2019



               Editor-in-Chief's message

               The ITU Journal: ICT Discoveries is a prime example of
               how  ITU  and  academia  can  work  together  towards  a
               shared  goal,  through  research  and  publication.  This
               collaborative  effort  is  of  mutual  benefit  to  ITU  and
               academia,  offering  research  communities the  chance  to
               influence the decisions of thought leaders in the public
               and private sector.
               Advances  in  radiowave  propagation  make  a  key
               contribution  to  the  efficient  use  of  the  radio-frequency
               spectrum.  This  third  special  issue  tackles  an  issue  of
               critical importance to the development of the global ICT
               ecosystem.

               In this issue of the ITU Journal, we find papers on topics
               including  a  comparison  of  site  diversity  experiments
               between  Greece  and  the  United  Kingdom  at  Ka  band,
               frequency  band  jamming  in  Paris,  directional  antenna  channel  modelling  in  urban  areas  using  ray
               tracing, and channel models for future networks and IMT-2020/5G systems.
               21  papers  were  submitted  and  underwent  an  extensive,  single-blind  review  process,  resulting  in  a
               publication offering a global view on radiowave propagation.
               I would like to thank ITU Secretary-General Houlin Zhao for entrusting me with the role of ITU Journal
               Editor-in-Chief.  I  would  also  like  to  thank  Chaesub  Lee,  Director  of  the  ITU  Telecommunication
               Standardization Bureau, for the support that I have received from his bureau, in particular the ITU
               Journal’s editorial team.

               I express my gratitude to all of our authors for their valuable contributions to this third special issue.
               I am also grateful to the many reviewers that ensured an efficient review process as well as our Guest
               Editors, Christopher R. Anderson, United States Naval Academy; Leke Lin, China Research Institute
               of Radio Wave Propagation; Carlo Riva, Politecnico di Milano; Sana Salous, Durham University; and
               Zhen-Wei Zhao, China Research Institute of Radio Wave Propagation.

               For their continued support to the ITU Journal, I would like to thank our Associate Editors-in-Chief,
               Rajkumar Buyya, University of Melbourne; Jun Kyun Choi, Korea Advanced Institute of Technology;
               Xiaolin Fu, University of Oxford; Mostafa Hashem Sherif; as well as our Outreach Chairman, Stephen
               Ibaraki.
               The fourth special issue of the ITU Journal will address the ‘future of video and immersive media’. We
               can look forward to papers highlighting the state of the art in multimedia as well as the new possibilities
               and associated challenges appearing on the horizon.
