No sooner have mobile operators started deploying 4G networks, than research and development into 5G has begun, noted Janette Stewart, principal at Analysys Mason. However, the diverging viewpoints emerging from different parties may pose a risk to the harmonised development of 5G, Stewart commented. Various regional research projects have now commenced, such as the EU's Mobile and wireless communications Enablers for the Twenty-twenty Information Society (METIS) project. The widespread interest in 5G is very positive in terms of the level of participation within the various research programmes. However, cooperation with work to define 5G at the International Telecommunication Union (ITU) could help achieve the full 5G vision that is emerging at present. Currently, 5G is a vision and wish-list, rather than a reality. Report
