Abstract:
The location of base stations (BSs) and mobile users
in the cellular network are typically modeled by poison point
process theory considering 2-D environment. These models are
suitable for the less dense rural or suburban environment, but
not suitable for a dense urban environment. Moreover, with
the admittance of Internet of Things (IoT), a large number of
self-operating devices have started connecting over the wireless
network. It necessitates the 5G wireless network to analyze the
performance of the system in a more realistic three dimensions
(3D) environment. In this work, we model and analyze the
performance of fractional frequency reuse (FFR)-aided dense
cellular network in a realistic 3-D environment. The proposed
model applies to any general environment. Based on the proposed
3-D cellular network model, the coverage probability (CP) and
average rate expressions are derived. Compared to traditional
2-D cell deployment, the proposed 3-D cell deployment is more
accurate, and provides a closer bound of CP and average rate.
It is shown that the performance of the cellular network in 2-
D network overestimates the actual performance of the cellular
network in 3-D environment.
