Coverage Analysis of Heterogeneous Cellular Networks in Urban Areas

TL;DR

This paper models urban heterogeneous cellular networks considering LOS and NLOS transmissions, revealing that diverse tier deployment improves coverage probability amidst urban blockages.

Contribution

It introduces a network model incorporating LOS and NLOS effects to analyze urban heterogeneous network coverage performance.

Findings

Coexistence of LOS and NLOS significantly impacts network performance.

Deploying multiple tiers enhances coverage probability more than single-tier deployment.

Urban blockages influence the effectiveness of different deployment strategies.

Abstract

In this article, a network model incorporating both line-of-sight (LOS) and non-line-of-sight (NLOS) transmissions is proposed to investigate impacts of blockages in urban areas on heterogeneous network coverage performance. Results show that co-existence of NLOS and LOS transmissions has a significant impact on network performance. We find in urban areas, that deploying more BSs in different tiers is better than merely deploying all BSs in the same tier in terms of coverage probability.
