  In this paper, we use the percentage blockage as a metric when an opaque disc
obstructs the Line-of-Sight link from the access point to the receiver in an
optical wireless indoor communication system. The effect of the different
parameters of the obstructing object are studied, these are the radius, the
height, and the horizontal distance from the receiver in the positive y
direction. The percentage of blocked room locations to the total number of room
locations when varying the disc parameters is studied assuming a single serving
link. It was found that depending on the dimensions of the obstructing object
and the distance from the receiver in addition to which access point is serving
the user, that blockage can vary between 0% up to 100%. Furthermore, the
service received by a user, in terms of beam blockage depends on the access
point they are connected to. The resulting fairness challenges will be
addressed in resource allocation optimization in future work.
