Indoor direction diversity at 5.8 GHz

Robert J. Achatz; Yeh Lo; Elizabeth E. Pol

Abstract: Complex impulse response measurements of a warehouse building were made at 5.8 GHz with a sliding correlator channel probe. These measurements were made with vertically and horizontally polarized directional antennas so performance improvement due to polarization- and direction-diversity could be evaluated. Improvement in performance was determined by changes in the radio channel's delay spread. Performance improved with direction diversity; however, adding polarization diversity yielded little improvement over direction diversity alone.

Keywords: delay spread; complex impulse response measurements; direction diversity; polarization diversity; indoor propagation
