Abstract: The present invention relates to a communication device and an access node. The communication device (100) comprises: a processor (102), and directional antennas (104); wherein the directional antennas (104) are configured to receive a first signal S1 indicating a calibration request (CR) for an access node (300); wherein the processor (102) is configured to generate directional beacon signals SDB in response to the calibration request (CR); wherein the directional antennas (104) further are configured to transmit the directional beacon signals SDB towards the access node (300). The access node (300) comprises: a processor (302), and an antenna array (304); wherein the antenna array (304) is configured to receive directional beacon signals SDB from at least one communication device (100); wherein the processor (302) is configured to calibrate the antenna array (304) based on the directional beacon signals SDB.

Abstract: A computing apparatus configured to communicate with nodes of a wireless communication system. The computing apparatus includes a processor configured to receive a radio link measurement corresponding to a user node. The processor determines a physical disturbance based on the radio link measurement and determines an at risk user node and a time at which the at risk user node is likely to experience a radio link disturbance, based on the physical disturbance. The processor then determines a connectivity adjustment for the at risk user node, and sends the determined connectivity adjustment to the wireless communication system.
