Very recent studies showed that the area spectral efficiency (ASE) of downlink cellular
networks will continuously decrease and finally crash to zero as the base station (BS) …

In this paper, we present a new and significant theoretical discovery. If the absolute height
difference between base station (BS) antenna and user equipment (UE) antenna is larger …

The impact of antenna downtilt on the performance of cellular WCDMA network has been
studied by using a radio network planning tool. An optimum downtilt angle has been …

The performance of a cellular network can be significantly improved by employing many
base stations (BSs), which shortens transmission distances. However, there exist no known …

In this letter, we investigate how network densification influences the performance of
downlink cellular network in terms of coverage probability (CP) and area spectral efficiency …

One major factor influencing the coverage and capacity in mobile networks is related to the
configuration of the antennas and especially the antenna tilt angle. By utilizing antenna tilt …

Antenna tilt is one of the most important performance tuning parameters of a cellular
network, since it has a strong impact on the inter-site interference level in the system. In this …

Performance of cellular networks is severely limited by intense inter-cell interference due to
aggressive frequency reuse among cells. How to characterize the dependency of inter-cell …

An optimal vertical antenna tilt in a wireless access network plays a key role for coverage
and capacity in the system. The autonomous (re-) optimization of tilts bears a large saving …

Despite the common belief that substantial capacity gains can be achieved by using more
antennas at the base-station (BS) side in cellular networks, the effect of BS antenna topology …
