Abstract

Measured channel characterization results are provided for six stairwells in the 5-GHz band, for two distinct stairwell types and two antenna polarizations. The stairwell channel is of interest for several applications, including Wi-Fi and public safety. Although other authors have reported stairwell path loss for other frequency bands (900 MHz, 2.4, 5.8 GHz), to our knowledge, ours is the first work at 5 GHz. More significantly, we report on floor attenuation factors and delay spread, which prior work has not thoroughly addressed. We measured power delay profiles and from these estimated propagation path loss and root-mean square delay spread (RMS-DS). Path loss exponents were between 5.5 and 8.3, and vertically polarized monopoles yield larger path loss and path loss exponents than horizontal polarization. Mean RMS-DS values ranged from 15 to 57 ns for link distances covering up to three flights of stairs. Copyright © 2015 John Wiley & Sons, Ltd.
