This Report provides information on many of the technology trends concerning radio access networks foreseen at the time of preparation of Recommendation ITU-R M.1645. The Report addresses technology topics that appear relevant to some lesser or greater degree to the future development of IMT-2000 and systems beyond IMT-2000. The Report considers these topics in three broad categories: ?C technologies which have an impact on spectrum@ its utilization and/or efficiency in this context; ?C technologies which relate to access networks and radio interfaces; ?C technologies which relate to mobile terminals.
