This document describes the determination of the cross-layer interference for a heterogeneous network.HetNet Stands in the statistical parameters using the mathematical tool StoGeo stochastic geometry that is based on the poisson point process, PPP. A two-tiers network with differing power and distribution patterns is proposed, although defined as independent and identically distributed at each tiers in the low power nodes NBP, NHP respectively, and they are presented under the homogenous PPP. Power is considered at each constant tiers and fading and interference distributions are planned under approximation models for gamma distribution.
