Abstract :
In this reported work, the blockage probability for the 60GHz radio links is analysed in typical indoor environments with random human activities. With up to Q random distributed human bodies, the average blockage possibility is calculated in the sense of statistics for the radio links between the user devices and the ceiling-mounted access point (AP) in a typical wireless LAN architecture. Also, the blockage impact to the effective channel capacity is quantified as a reduction related to the blockage probability. Numerical simulations show that the blockage probability increases almost linearly as the user devices are moving towards the edge of the service area, and the increasing rate is largely affected by the height of the AP and the human density.
