Abstract :
In this outdoor propagation study low antenna heights of 1.7 m are used at both the transmitter and the receiver to measure wideband (100 MHz baseband) power-delay profiles (PDPs) of the channel for a peer-to-peer communications system operating at 1.8 GHz. Rural and urban areas are studied in 22 different transmitter-receiver links, and the path loss and delay spread characteristics are presented. The small-scale multipath fading characteristics are measured in detail by recording 160 PDPs within each local area. This paper shows the measurement setup for calculation of the fading rate variance and the estimation of the angular spread of each multipath component. The accuracy of the angular spread is discussed
