Abstract

We study the temporal fluctuations of a fixed wireless link in an urban environment by characterizing the Ricean K-factor as a function of the positioning of the customer premises antenna. Our main observation is that temporal fluctuation of received power is due mainly to vehicular traffic close to the remote antenna. Furthermore, a strong correlation between average envelope power and K-factor is observed when placing the remote antenna at similar distances to traffic. Therefore, optimizing antenna placement based on received power reduces fade depth at the same time.
