摘要

Spatio-temporal channel sounding was performed at frequency bands of 15,28 and 60 GHz in the backhaul-link street canyon scenario. Analysis of the measured channels from the sounding show 1) path loss exponents close to the free-space in the line-of-sight condition, with extra losses of 5 to 30 dB in the non-line-of-sight conditions; 2) the azimuth angular and delay spreads mostly less than 25° and 30 ns at the three frequency bands; 3) decreasing angular and delay spreads as the link distance is longer, 4) up to fourth-order specular reflection observed in the 100-m long street canyon when looking at the strongest 30-dB dynamic range of the channels, and finally, 5) no decisive frequency dependency of the angular and delay spreads and the reflection order, though the presence or absence of cars in the street canyon during the measurements seemed to make some impacts on the spread values given the antenna height of our channel sounding.
