Title:	5 GHz Wireless Channel Characteristics on The Ohio University Campus
Author:	Pai, Guruprasad
Description:	This thesis presents a wideband statistical wireless channel characterization for a campus environment in the band around 5120 MHz (just below the Unlicensed National Information Infrastructure (UNII) bands), based upon measurements. To accomplish these measurements, the stationary transmitter was placed on the rooftop of three separate buildings, and the receiver was moved along the ground at pedestrian velocities. The measurement locations chosen were segregated into line of sight (LOS) and non line of sight (NLOS) regions. Important channel parameters, including delay spread and coherence bandwidth, were obtained from power delay profiles, collected using the 50 MHz bandwidth signal. From the measured data, the thesis provides channel models for a 50 MHz bandwidth and other smaller values of bandwidth, by specifying the number of “taps” in the common tapped delay line model, and the tap’s amplitude statistics and relative energies. The channel models are validated by comparing our simulated channel output statistics to those of the measured data; agreement between model and data is reasonable.
