Propagation Measurements for Fixed Wireless Loops (FWL) in a Suburban Region with Foliage and Terrain Blockages

We present the results of propagation measurements for Fixed Wireless Loop. Path-loss measurements were performed and characterized at 45 subscriber locations around a base station antenna located on top of Crawford Hill in Holmdel, NJ. This suburban location is characterized by rolling hills, foliage and terrain blockages. Temporal and horizontal motion pathloss fluctuations were found to be uncorelated each characterized by a different Rician distribution. Lower r.m.s delay spreads were obtained with directive subscriber antennas than with omni-directional antennas. No substantial gain loss (less then 2dB) of subscribers' directive antennas was observed. The effects of trees, with foliage, surrounding the base station upon the pathloss and the ratio of scattered power to specular power are also examined.
