  The higher moments of the net charge distributions, e.g. the skewness and
kurtosis, are studied within an infinite hadronic matter calculation in a
transport approach. By dividing the box into several parts, the volume
dependence of the fluctuations is investigated. After confirming that the
initial distributions follow the expectations from a binomial distribution, the
influence of quantum number conservation in this case the net charge in the
system on the higher moments is evaluated. For this purpose, the composition of
the hadron gas is adjusted and only pions and $\rho$ mesons are simulated to
investigate the charge conservation effect. In addition, the effect of imposing
kinematic cuts in momentum space is analysed. The role of resonance excitations
and decays on the higher moments can also be studied within this model. This
work is highly relevant to understand the experimental measurements of higher
moments obtained in the RHIC beam energy scan and their comparison to lattice
results and other theoretical calculations assuming infinite matter.
