Abstract: Method for managing a wireless passive optical network, including a plurality of access points, APs, and a plurality of customer premises equipments, CPEs. The method includes configuring an AP to CPE association based on a load balancing algorithm such that each CPE is associated with at least one AP; configuring for each AP an AP beamforming codebook based on the configured association, wherein the AP beamforming codebook includes entries, wherein each entry is representative for a beam pattern to be transmitted by the AP, and wherein the AP beamforming codebook includes for each CPE associated with the AP—a line of sight, LoS, entry representative for a beam pattern to be transmitted to the respective CPE via a LoS path; and at least one back-up entry representative for a beam pattern to be transmitted to the respective CPE via a back-up path different from the LoS path.
