Path loss measurements for a non-line-of-sight mobile-to-mobile environment

This paper shows results of narrowband path loss measurements in a typical urban and suburban mobile-to-mobile radio environment at 900 MHz band. The measurements were made with two omni-directional antennas with a transmitter and a receiver antenna height of 1.5 meters. The results of measurements provide practical values for path loss exponent and standard deviation of shadowing in a non-line-of-sight radio environment. These parameters can be used with a simple power law path loss model to predict reliable communication ranges for future communication systems operating in a mobile-to-mobile environment, such as a relay extended cellular networks, non-line-of-sight vehicle-to-vehicle communications or relay assisted positioning applications.
