Abstract

Quasi-Deterministic Channel Propagation Model for 60 GHz Urban WiFi Access from Light Poles S.Y. Jun, C. Lai, D. Caudill, J. Wang, J. Senic, N. Varshney, C. Gentile. Quasi-Deterministic Channel Propagation Model for 60 GHz Urban WiFi Access from Light Poles. IEEE Antennas and Wireless Propagation Letters. Published online Apr 29, 2022. doi: 10.1109/LAWP.2022.3171503. Abstract There is strong impetus by the Telecom Infra Project to exploit the 60 GHz unlicensed band for public WiFi in urban environments, by installing access points on light poles. Although many 60 GHz urban channel measurements have been recorded to date, they have resulted only in path loss models or RMS delay spreads. What is needed at millimeter-wave is a spatially consistent channel model for beamtracking that embodies the characteristics of these short wavelengths sparsity and rough surface scattering such as the Quasi-Deterministic model. In this letter, we fit the model to channel measurements we recorded in an urban environment. The measurements were recorded at 4 m, 6 m, and 9 m antenna heights to investigate the tradeoffs between light pole heights. The large-scale channel metrics between the model and the measurements were shown to match very well. ieeexplore.ieee.org
