Summary
At present, every network operator is looking for a cost‐effective and spectrally efficient solution not only for better coverage but also to offer higher data rates. Stochastic‐based heterogeneous cellular networks have taken over the thoroughly planned traditional hexagonal grid networks. Heterogeneous networks typically include multiple tiers of base stations and small cells. This paper presents an analysis of a cellular network with cell‐edge, uncovered, and hotspot (HS) users based on spatial bivariate Poisson Point Process. The work compares the relationship between small cell intensity for cell‐edge and HS user's intensity within macrocell area. The variations in small cell intensity for uncovered and HS users outside macrocells are also presented. The simulation results depict higher small cell intensity in cell‐edge areas as compared with HS areas within the macrocells, while for outside of macrocells, small cell intensity in HS areas is much higher than that for uncovered areas. The expected numbers of small cell inside and outside macrocells are obtained along with the total new cells required for the proposed model.
