Wideband mobile propagation measurements at 3.7 GHz in an urban environment

An experimental mobile broadband communication system has been developed for the purpose of implementing and evaluating candidate physical-layer technologies in a mobile cellular environment (Batariere, M.D. et al., Proc. Mobile and Portable Radio Research Group Wireless Symposium, 200 1; Proc. IEEE VTC-2002/Spring, 2002; Kepler, J.F. et al., Proc. IEEE VTC-2002/Fall, 2002). The data collected by this experimental system can also be used to characterize the path loss, delay spread, and other channel characteristics in a 20 MHz bandwidth at 3.676 GHz. The paper describes these statistics for a dense, urban environment for two base antenna heights transmitting to handheld and vehicle rooftop receive antennas.
