Summary:This paper presents details of indoor wideband directional propagation measurements at 26 GHz, in which a wideband channel sounder using a millimeter wave (mmWave) signal analyzer and vector signal generator was employed. The setup provided 2 GHz bandwidth, and the mechanically steerable directional lens antenna with a narrow beamwidth provided 5 degrees of resolution in the azimuth direction. Measurements include the path loss, delay spread and spatial spread of the channel. Angular and delay dispersion are presented for line-of-sight (LoS) and non-line-of-sight (NLoS) scenarios. When the receiving antenna was close to the edge of a wall, significant NLoS components were received, demonstrating that signal coverage can be achieved outside of LoS at mmWave frequencies.
