Abstract
Next-generation wireless networks will utilize millimeter-wave (mmWave) frequencies to achieve significantly higher data rates. However, due to the high path loss at mmWave frequencies, accurate channel measurement and modeling for different deployment sites is required. We conducted an extensive mmWave channel measurement campaign with over 2,800 links on 24 sidewalks in the COSMOS testbed deployment area in West Harlem, New York City between March and August 2019, and Fall 2020. Results on the measured path gains, the effective azimuth beamforming gains, and the signal-to-noise ratio (SNR) coverage are presented for various locations and settings. These results can inform future COSMOS testbed development, including the deployment of IBM 28 GHz phased array antenna modules and provide a benchmark for other deployments in dense urban environments.
