Coverage Analysis in Millimeter Wave Cellular Networks with Reflections

TL;DR

This paper models and analyzes the impact of reflectors on mmWave cellular network coverage using stochastic geometry, finding that reflections have minimal effect on coverage probability.

Contribution

It introduces a novel stochastic geometry model to evaluate the influence of reflectors on mmWave coverage, a topic not previously addressed.

Findings

Reflections have negligible impact on coverage probability.

The model shows that line-of-sight paths dominate coverage.

Reflections do not significantly improve coverage in mmWave networks.

Abstract

The coverage probability of a user in a mmwave system depends on the availability of line-of-sight paths or reflected paths from any base station. Many prior works modelled blockages using random shape theory and analyzed the SIR distribution with and without interference. While, it is intuitive that the reflected paths do not significantly contribute to the coverage (because of longer path lengths), there are no works which provide a model and study the coverage with reflections. In this paper, we model and analyze the impact of reflectors using stochastic geometry. We observe that the reflectors have very little impact on the coverage probability.
