Abstract
A method for alignment of a first node with a second node in a wireless communication network. The method comprises directing a first node first antenna beam at a first pointing angle, using a second node antenna beam for scanning a first volume with objects being able to generate signal reflections/diffraction, detecting a first signal property of reflected/diffracted signals; and saving scan angles resulting in said first signal property exceeding a first threshold level. The method further comprises directing the second node antenna beam at said saved angles, and, for each such angle: using a first node second antenna beam for scanning; and detecting at least a second signal property of reflected/diffracted signals; exchanging information between the nodes comprising first node second antenna beam pointing direction angles resulting in said second signal property exceeding a second threshold level and said saved angles; and selecting angles for communication.
