This paper aims to show the effect of macrocellular
network densification on the capacity, energy and
cost
efficiency. The presented results are based on radi
o propagation simulations that consider macrocellul
ar
network with different intersite distances, i.e. d
ifferent site densities, and also take into account
the
presence of indoor receiver points by varying outdo
or and indoor receiver distribution. It is observed
that
as a result of densifying the network, the cell spe
ctral efficiency reduces due to increasing level of
intercell
interference. However, as a result of densification
, the network area capacity can be improved since t
he
area spectral efficiency increases. Nevertheless, t
he densification efficiency decreases because of th
e
reduction of cell spectral efficiency, especially w
hen indoor receiver points are taken into account.
The
results hence indicate that densification of macroc
ellular network suffers from inefficiency which res
ults in
higher energy and cost per bit per Hertz, and thus
calls for alternative methods to deploy networks, o
r
alternatively, more sophisticated methods, such as
base station coordination or intercell interferenc
e
cancellation techniques, to be implemented for futu
re cellular networks.
