Massive MIMO has been identified as one of the key
technologies for the 5th generation of mobile cellular networks.
By utilizing 2D antenna arrays with a large number of antenna
elements, it enables to form orthogonal beams towards spatially
separated User Equipments (UEs). In this paper we evaluate the
channel energy and the average throughput of typical indoor- and
outdoor UEs at various heights and distances to the macro site.
Our goal is to demonstrate the achievable spatial resolution of
the beamforming in vertical direction with large antenna arrays.
Existing work on directional beamforming strategies is commonly
based on simplistic signal propagation assumptions under LOS
conditions. This paper considers a realistic 3D channel model that
also accounts for multi-path propagation under NLOS conditions.
Our results exhibit the dependency of the achievable spatial
resolution on both, the size of the antenna array as well as the
channel conditions. They show that depending on whether the
UE is located indoors or outdoors, the channel has an opposing
impact on the achievable spatial resolution.
