Wideband Measurement and Analysis of Human Blocking on the Indoor Radio Channel at 60 GHz

Overview & Synopsis

In millimeter band used for wireless communication systems, there is a strong blocking impact introduced by the human body. At 60 GHz, the coverage of these systems is relatively limited due to high propagation losses. Hence, the use of the beamforming makes it possible to find a reflective path to replace the blocked one. The objective of this work focuses on the impact of a human blocker in a meeting room, to evaluate the blocking losses introduced by the human body at 60 GHz. The results obtained both by calculating the path loss and the impulse response of the channel show that the attenuation due to the human body is between 24 and 26 dB. In addition, the results show that the use of beamforming make it possible to exploit the reflected paths to overcome the cutoff of the radio link due to human blocking.
