Abstract: The invention refers to a diverging beam wireless network node including multiple bidirectional point-to-point links, which align between a central hub and dispersed clients. Assuming that the hub is limited in size, the receivers may be in close proximity to one another. In this case, the optical signal from two or more clients, which may have spread significantly in diameter due to angular spread in the transmitted light, may overlap spatially at the hub, causing interference and difficulty in separating the data. The invention solves the problems caused by such interference and permits communication links with low error rate.
