Abstract

Overview

Recent initiatives by the Telecom Infra Project aim to leverage the 60 GHz unlicensed band for providing public WiFi in urban settings. This involves setting up access points on light poles to enable communication.

Findings

Prior studies have focused mainly on path loss models or RMS delay spreads at similar frequencies. This study introduces a Quasi-Deterministic model fitted specifically to urban channel measurements for 60 GHz. Measurements were taken at various heights (4 m, 6 m, 9 m) to explore the impact of light pole heights on transmission.

• Implementation of a spatially consistent channel model for millimeter-wave frequencies was critical.
• The characteristics of the model include sparsity and rough surface scattering, relevant for beamtracking applications.
• The comparison between the model and real urban environment measurements shows a high degree of accuracy in channel metrics.

Conclusion

The study successfully fits a novel Quasi-Deterministic model to urban electromagnetic fields at 60 GHz, which aligns closely with experimental data, potentially enhancing the safety and efficacy of urban WiFi systems through improved understanding of EMF propagation and its health implications.
