Abstract

Overview

The study emphasizes the utilization of the 60 GHz unlicensed band for public WiFi setups in urban settings, facilitated by mounting access points on light poles. This initiative is strongly supported by the Telecom Infra Project.

Findings

Despite numerous measurements of 60 GHz urban channels previously focusing on path loss models or RMS delay spreads, there is a significant need for a model that accommodates the unique propagation behaviors at millimeter-wave frequencies such as sparsity and rough surface scattering. The Quasi-Deterministic model introduced in this letter addresses these aspects.

Utilizing channel measurements taken at various antenna heights (4 m, 6 m, and 9 m), the study explores the interplay between antenna placement height and channel propagation features. These measurements were systematically fitted into the proposed model showcasing high correlation with large-scale channel metrics.

Conclusion

The correspondence between the channel metrics from the implemented model and recorded measurements underscores the model’s robustness in simulating real-world urban electromagnetic environments, highlighting implications for electromagnetic field health risks.
