  This invited paper discusses the challenging task of assessing the
millmeter-wave spectrum for the use of 5G mobile systems. 3 key KPIs related to
mobile systems, coverage, capacity and mobility are individually assessed and
quantified with a simplistic figure of merit (FoM). The coverage and capacity
KPIs are assessed through simulations while an analytical approach is developed
for mobility. The key message is that the FoM degrades with the higher as the
frequencies increase in this range. This indicates that there will be more
challenges in deploying millimeter wave systems in higher frequencies, but
these are not insurmountable. Many of these challenges are addressed in the
mmMAGIC project and possible solutions are derived.
