  This paper presents a tutorial on stochastic geometry (SG) based analysis for
cellular networks. This tutorial is distinguished by its depth with respect to
wireless communication details and its focus on cellular networks. The paper
starts by modeling and analyzing the baseband interference in a basic cellular
network model. Then, it characterizes signal-to-interference-plus-noise-ratio
(SINR) and its related performance metrics. In particular, a unified approach
to conduct error probability, outage probability, and rate analysis is
presented. Although the main focus of the paper is on cellular networks, the
presented unified approach applies for other types of wireless networks that
impose interference protection around receivers. The paper then extends the
baseline unified approach to capture cellular network characteristics (e.g.,
frequency reuse, multiple antenna, power control, etc.). It also presents
numerical examples associated with demonstrations and discussions. Finally, we
point out future research directions.
