Urban millimeter wave networks

Millimeter wave networks are sensitive to blockages due to densely distributed buildings in urban areas. This is critical for vehicle-to-infrastructure networks, which are cellular networks designed to support emerging vehicular applications. Most popular pathloss models use only the Euclidean distance between the transmitter and the receiver to characterize the channel, but in urban environments where severe blockages caused by buildings is often encountered, Euclidean distance does not provide enough information to characterize the pathloss.
