Measurements of large-scale variations caused by vehicular traffic in small-cells

Abstract

This paper presents and characterizes large-scale variations of received power generated by vehicular traffic crossing a radio link. Measurements in the 2 GHz band for several small-cell configurations involve various transmitter heights, link distances and urban densities. Observations showed that stronger losses up to 30 dB are due to medium to high vehicles. Lower vehicles have a smaller impact in links perpendicular to traffic, but amplitude variations and duration can reach larger values when the receiver is at cell radius limits.
