It can be understood that an increased bandwidth, through
the move to mmWave and a better use of unlicensed spectrum
will be needed and the technological challenges it implies
have to be solved, as it should provides a ubiquitous high-rate,
low-latency experience for network users. On the other hand,
increased spectral efficiency and utilization, most through
advanced MIMO, is to be adopted. Extreme densification and
offloading are also key factors of capacity enhancement
