The influence of elevation angle on 60 GHz near-body path gain

Indoor millimeter-wave wireless access points will necessarily be placed relatively high on walls and ceilings to reduce shadowing and blocking effects and to improve coverage. This means that the access point will be at a range of elevation angles with respect to the user equipment. A series of experiments were conducted in an anechoic chamber to investigate the influence of elevation angle on non-line-of-sight near-body path gain at 60 GHz. An analysis of the measurement results shows that, compared to low elevation angle scenarios, high elevation angles of incidence provide better performance at 60 GHz with between 10 dB and 15 dB higher path gain.
