There is growing interest in using millimeter wave (mmWave) frequencies for future access communications based on the enormous amount of available spectrum. To characterize the mmWave channel in urban areas, wideband propagation measurements at 73 GHz have recently been made in New York City. Using the measurements, a ray-tracing study has been conducted using databases for the same environments as the measurements, allowing a simple ray-tracer to predict measured statistics such as path loss and angles of arrival in the same physical environment of the measurements. In this paper a preliminary 3GPP-style 3D mmWave channel model is developed with special emphasis on using the ray tracer to determine elevation model parameters. The channel model includes distance-dependent elevation modeling which is critical for the expected 2D arrays which will be employed at mmWave.
