Extension of the ITU-R P.1411-8 urban path loss models to high antennas

This paper presents an extension of the ITU-R P.1411-8 urban low antenna path loss models to higher antennas. The Line-of-Sight (LOS) and non-Line-of-Sight (NLOS) urban canyon models presented in the paper are typically used for street level peer-to peer or cellular communications, but can be more generally used to account for radio waves propagating through urban street canyons. It is shown through comparisons with measurements of varying transmit antenna height and large variations of height difference between transmit and receive antennas, that the presented urban street canyon models are applicable to taller microcellular antennas. The measurements that are used in the comparisons and analysis were obtained in an urban high-rise environment in San Francisco at 850 and 1920 MHz frequencies.
