“…These parameters are relevant for the simulation of upper-layer protocols. Our results will also complement [8], [12] and references quoted therein, by reporting the effect of multiple pedestrians (from one to seven) blocking the LOS. This is especially relevant for the design of channel or crosslayer simulators that allow computing performance metrics of upper-layer protocols.…”

“…The STA was installed 5 m away from the AP, at 1.1 m height. In a previous measurement campaign [12], we did not observe significant signal losses when a human walked in the proximity of the link. This was attributed to the spatial filtering of the directional pattern of transmit and receive antennas.…”

“…This means that blocking the vicinity of the LOS only produced very shallow fades. Authors in [12] also observed this phenomenon when using highly directive antennas (12 • ). They concluded that significant fades only occur if the LOS is blocked.…”

“…This setup is similar to the one reported in [20]. However, in our case, the geometry is different (in [20] both AP and STA are at the same height), and we model a wider blockage (References [12] and [20] studied the effect of a single pedestrian crossing the link at different positions).…”

“…In [12], the authors empirically analyzed the impact of a single pedestrian using a 60 GHz indoor-indoor link. They modeled fade depths and decay/rise time of fades, showing more significant losses than those reported in the literature on this topic when only one pedestrian crosses the LOS (up to 48 dB).…”

Satisfying the exponential data growth is one of the main challenges for the design of future wireless networks. Given the abundant spectrum availability at millimeter-wave bands, exploiting these frequencies is a natural choice. WiGig (also known as 60 GHz WiFi) allows multi-gigabit transmissions in short range wireless links. The maximum data transfer rates occur in line of sight (LOS) connections. Given the small operating wavelength, obstructing the LOS causes significant power losses, severely impacting the attainable throughput of each user. This article presents empirical results to parameterize typical small-scale fades caused by pedestrians when blocking the LOS, in areas where a WiGig access point serves indoor users. Our results show that fades can be as large as 21 dB, in average. Furthermore, burst of fades are common, lasting up to 5200 ms in 90% of the observed cases. INDEX TERMS 60 GHz, human blockage, human shadowing events, millimeter wave propagation, pedestrian traffic.

As the millimeter‐wave (mm‐Wave) spectrum is considered to be an essential enabler to the fifth generation (5G) wireless communication systems. Human movements are one of the most significant factors that cause transient blockage in indoor mm‐wave channels. In this letter, human blockage measurements and shadow fading statistics due to human body movements in an indoor office environment are reported for the 28 GHz band. The effect of human bodies on the channel is measured for several scenarios including a variety of population and using diverse antenna heights. The reported shadow fading statistics include both the duration and the depth of the blockage fade, and accordingly, we propose several empirical models that cater for such blockage events. The findings reported in this letter could improve the modeling of indoor radio channels at 28 GHz bands by considering the presence of humans, as well as their movements.
